Definitions

As used herein, the term “pectin”, or “pectic polysaccharide” refers to a polysaccharide, e.g., a polysaccharide occurring in a plant cell wall or a middle lamella, e.g., a galacturonic acid-rich polysaccharide. Exemplary pectins include homogalacturonans, rhamnogalacturonan I, and the substituted galacturonans rhamnogalacturonan II (RG-II) and xylogalacturonan (XGA). Pectins may be classified as low-methoxyl pectins or high-methoxyl pectins based on the degree of methyl esterification.

In some aspects, the degree of methyl esterification is at least 5%, at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or 100% methyl esterification.

In one example, the pectin is low-methoxyl pectin, e.g., a pectin having less than 50% methyl esterification. Gelation (e.g., increased viscosity of a preparation or solution comprising pectin) of low-methoxyl pectin results from ionic linkage between two carboxyl groups belonging to two different pectin chains via calcium bridges. Gelation of low-methoxyl pectin is increased in the presence of calcium, e.g., Ca²⁺ ions.

In another example, the pectin is high-methoxyl pectin, e.g., a pectin having 50% or more methyl esterification. Gelation of high-methoxyl pectin results from cross-linking of pectin molecules, involving a combination of hydrogen bonds and hydrophobic interactions between the pectin molecules.

In some aspects, the pectin is a high molecular weight pectin. Pectins having higher molecular weight have higher viscosity. Viscosity may be measured, for example, as described in Sayah et al., PLoS ONE, 11(9), e0161751, 2016.

The presence and amount of pectin in a substance (e.g., a plant preparation) may be detected using any known assay for pectins. For example, the assay may be performed using a Pectin Identification Assay Kit (Megazyme; K-PECID). The assay may involve treating the substance with an enzyme, e.g., a pectinase, and measuring the level of an enzymatic product of pectin, e.g., a sugar. The assay may be a colorimetric assay, e.g., a colorimeteric assay to detect galacturonic acid, a component of pectin, following contacting the substance with a pectinase and 3,5-dinitrosalicylic acid (DNS).

As used herein, the term “pectin-rich” refers to a substance, e.g., a plant preparation, comprising more than 0.01%, more than 0.05%, more than 0.1%, more than 0.5%, more than 1%, more than 5%, or more than 10% pectin. In other examples, a “pectin-rich” preparation may include between 0.1%-10% pectin, for example, between 0.5%-5% pectin.

As used herein, the term “pectinase” or “pectic enzyme” refers to an enzyme or a mixture of enzymes capable of degrading a pectin. Exemplary pectinases include pectolyase (pectin lyase) and polygalacturonase (pectin depolymerase).

As used herein, the term “plant preparation” refers to a product resulting from preparing or processing of a plant or a plant part. The plant preparation may be a liquid, a gel, or a gel-like solution. In one example, the viscosity of the plant preparation is 1.4 cP at 20° C. In other examples, the plant preparation is a blended plant or a blended plant part (e.g., a blended citrus fruit or a blended juice sac of a citrus fruit). In other aspects, the plant preparation is the product of a plant or a plant part (e.g., a citrus fruit or a juice sac of a citrus fruit) being mashed through a strainer. In other examples, the plant preparation is the product of cold pressing a plant or a plant part (e.g., a citrus fruit or a juice sac of a citrus fruit). A plant preparation may contain, without limitation, plant cell wall components; pectin; plant organelles (e.g., mitochondria; plastids such as chloroplasts, leucoplasts or amyloplasts; and nuclei); plant chromatin (e.g., a chromosome from the nucleus); or plant molecular aggregates (e.g., protein aggregates, protein-nucleic acid aggregates, lipoprotein aggregates, or lipido-proteic structures), or any other cellular or apoplastic component found in a plant or a plant part.

As used herein, the term “chelation” refers to the process of treating a preparation, solution, or system comprising a metal ion with a chelating agent (chelator). Typically, the chelating agent binds the metal ion to form a chelate (i.e., a compound having a metal ion covalently bound to two or more non-metallic ions in the compound), thus diminishing the chemical effect (e.g., reactivity) of the metal ion in the preparation, solution, or system. In some aspects, the metal ion is a calcium ion (e.g., Ca²⁺), a magnesium ion (e.g., Mg²⁺), an iron ion, a lead ion, or a copper ion. Chelating agents include, but are not limited to ethylenediaminetetraacetic acid (EDTA) and ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetraacetic acid (EGTA). The chelating agent may be formulated with sodium hydroxide (NaOH). In other examples, the chelating agent is formulated with 2-(N-morpholino)ethanesulfonic acid (MES), tris(hydroxymethyl)aminomethane (Tris), or phosphate buffered saline (PBS).

As used herein, the term “chelated preparation” or “chelated solution” refers to a preparation or solution treated with a chelating agent in an amount and for a time sufficient to diminish the reactivity of a metal ion in the solution by at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or 100%. In some aspects, the reactivity of the metal ion is quantified as esterification of pectins, e.g., in an assay for viscosity or turbidity of the solution.

As used herein, the term “juice sac” or “juice vesicle” refers to a juice-containing membrane-bound component of the endocarp (carpel) of a hesperidium, e.g., a citrus fruit. In some aspects, the juice sacs are separated from other portions of the fruit, e.g., the rind (exocarp or flavedo), the inner rind (mesocarp, albedo, or pith), the central column (placenta), the segment walls, or the seeds. In some aspects, the juice sacs are juice sacs of a grapefruit, a lemon, a lime, or an orange.

As used herein, the term “turbidity” or “turbid” refers to the relative opacity or cloudiness of a liquid, solution, or preparation (e.g., a PMP preparation), e.g., due to particulate matter suspended in the solution (e.g., pectin). Turbidity may be measured by, e.g., measuring the absorbance or optical density of a liquid, solution, or preparation at 650 nm (A_{650 nm} or OD650). Other wavelengths (e.g., wavelengths greater than 650 nm) may also be appropriate for measuring turbidity.

PMPs may optionally include additional agents, such as heterologous functional agents, e.g., pesticidal agents, fertilizing agents, plant-modifying agents, therapeutic agents, polynucleotides, polypeptides, or small molecules. The PMPs can carry or associate with additional agents (e.g., heterologous functional agents) in a variety of ways to enable delivery of the agent to a target plant, e.g., by encapsulating the agent, incorporation of the agent in the lipid bilayer structure, or association of the agent (e.g., by conjugation) with the surface of the lipid bilayer structure. Heterologous functional agents can be incorporated into the PMPs either in vivo (e.g., in planta) or in vitro (e.g., in tissue culture, in cell culture, or synthetically incorporated).

DETAILED DESCRIPTION OF THE INVENTION

Featured herein are methods for manufacturing of industrial and scaled preparations of PMPs, e.g., methods of manufacturing commercially acceptable and/or pharmaceutically acceptable preparations of PMPs, e.g., Good Manufacturing Practices (GMP) preparations of PMPs. Such methods may include one or more of chelation, enzymatic digestion, and differential separation (e.g., by centrifugation or tangential flow filtration), which will, e.g., clarify the solution, reduce its viscosity, reduce undesired components or contaminants, and/or enrich the preparations in PMPs so as to enable utilization at higher volume/mass scales. The PMPs manufactured using the methods herein are useful in a variety of agricultural and therapeutic compositions and methods.

I. PMP Production Methods

A plant messenger pack (PMP) is a lipid (e.g., lipid bilayer, unilamellar, or multilamellar structure) structure that includes a plant EV, or segment, portion, or extract (e.g., lipid extract) thereof. A plant EV is an enclosed lipid-bilayer structure that naturally occurs in a plant. Plant EVs may be about 5-2000 nm in diameter. Plant EVs can originate from a variety of plant biogenesis pathways. In nature, plant EVs can be found in the intracellular and extracellular compartments of plants, such as the plant apoplast, the compartment located outside the plasma membrane and formed by a continuum of cell walls and the extracellular space. Alternatively, PMPs can be enriched plant EVs found in cell culture media upon secretion from plant cells. Plant EVs can be separated from plants (e.g., from the apoplastic fluid), thereby providing PMPs, by a variety of methods further described herein. Further, the PMPs can optionally include a heterologous functional agent (e.g., a heterologous agricultural agent (e.g., pesticidal agent, fertilizing agent, herbicidal agent, plant-modifying agent) or a heterologous therapeutic agent (e.g., a pathogen control agent such as an antifungal agent, an antibacterial agent, a virucidal agent, an anti-viral agent, an insecticidal agent, a nematicidal agent, an antiparasitic agent, or an insect repellent)), which may be introduced (e.g., loaded into or onto the PMP) in vivo or in vitro.

As such, the PMPs can include a heterologous functional agent that is loaded into or onto the PMP by the plant from which the PMP is produced. For example, the pesticidal agent loaded in to the PMP in vivo may be a factor endogenous to the plant or a factor exogenous to the plant (e.g., as expressed by a heterologous genetic construct in a genetically engineered plant). Alternatively, the PMPs may be loaded with a heterologous functional agent in vitro (e.g., following production by a variety of methods further described herein).

PMPs can include plant EVs, or segments, portions, or extracts, thereof, in which the plant EVs are about 5-2000 nm in diameter.

A variety of methods (e.g., a dynamic light scattering method) standard in the art can be used to measure the particle diameter of the plant EV, or segment, portion, or extract thereof.

In some instances, the PMP may include a plant EV, or segment, portion, or extract thereof, that has a mean surface area of 77 nm² to 3.2×10⁶ nm² (e.g., 77-100 nm², 100-1000 nm², 1000-1×10⁴ nm², 1×10⁴-1×10⁵ nm², 1×10⁵-1×10⁶ nm², or 1×10⁶-3.2×10⁶ nm²). In some instances, the PMP may include a plant EV, or segment, portion, or extract thereof, that has a mean volume of 65 nm³ to 5.3×10⁸ nm³ (e.g., 65-100 nm³, 100-1000 nm³, 1000-1×10⁴ nm³, 1×10⁴-1×10⁵ nm³, 1×10⁵-1×10⁶ nm³, 1×10⁶-1×10⁷ nm³, 1×10⁷-1×10⁸ nm³, 1×10⁸-5.3×10⁸ nm³).

In some instances, the PMP can have the same size as the plant EV or segment, extract, or portion thereof. Alternatively, the PMP may have a different size than the initial plant EV from which the PMP is produced. For example, the PMP may have a diameter of about 5-2000 nm in diameter. For example, the PMP can have a mean diameter of about 5-50 nm, about 50-100 nm, about 100-150 nm, about 150-200 nm, about 200-250 nm, about 250-300 nm, about 300-350 nm, about 350-400 nm, about 400-450 nm, about 450-500 nm, about 500-550 nm, about 550-600 nm, about 600-650 nm, about 650-700 nm, about 700-750 nm, about 750-800 nm, about 800-850 nm, about 850-900 nm, about 900-950 nm, about 950-1000 nm, about 1000-1200 nm, about 1200-1400 nm, about 1400-1600 nm, about 1600-1800 nm, or about 1800-2000 nm.

A variety of methods (e.g., a dynamic light scattering method) standard in the art can be used to measure the particle diameter of the PMPs. In some instances, the size of the PMP is determined following loading of heterologous functional agents, or following other modifications to the PMPs.

In some instances, the PMP may have a mean surface area of 77 nm² to 1.3×10⁷ nm² (e.g., 77-100 nm², 100-1000 nm², 1000-1×10⁴ nm², 1×10⁴-1×10⁵ nm², 1×10⁵-1×10⁶ nm², or 1×10⁶-1.3×10⁷ nm²).

In some instances, the PMP may have a mean volume of 65 nm³ to 4.2×10⁹ nm³ (e.g., 65-100 nm³, 100-1000 nm³, 1000-1×10⁴ nm³, 1×10⁴-1×10⁵ nm³, 1×10⁵-1×10⁶ nm³, 1×10⁶-1×10⁷ nm³, 1×10⁷-1×10⁸ nm³, 1×10⁸-1×10⁹ nm³, or 1×10⁹-4.2×10⁹ nm³). In some instances, the PMP has a mean surface area of at least 77 nm², (e.g., at least 77 nm², at least 100 nm², at least 1000 nm², at least 1×10⁴ nm², at least 1×10⁵ nm², at least 1×10⁶ nm², or at least 1×10⁷ nm²).

In some instances, the PMP may include an intact plant EV. Alternatively, the PMP may include a segment, portion, or extract of the full surface area of the vesicle (e.g., a segment, portion, or extract including less than 100% (e.g., less than 90%, less than 80%, less than 70%, less than 60%, less than 50%, less than 40%, less than 30%, less than 20%, less than 10%, less than 10%, less than 5%, or less than 1%) of the full surface area of the vesicle) of a plant EV. The segment, portion, or extract may be any shape, such as a circumferential segment, spherical segment (e.g., hemisphere), curvilinear segment, linear segment, or flat segment. In instances where the segment is a spherical segment of the vesicle, the spherical segment may represent one that arises from the splitting of a spherical vesicle along a pair of parallel lines, or one that arises from the splitting of a spherical vesicle along a pair of non-parallel lines. Accordingly, the plurality of PMPs can include a plurality of intact plant EVs, a plurality of plant EV segments, portions, or extracts, or a mixture of intact and segments of plant EVs. One skilled in the art will appreciate that the ratio of intact to segmented plant EVs will depend on the particular isolation method used. For example, grinding or blending a plant, or part thereof, may produce PMPs that contain a higher percentage of plant EV segments, portions, or extracts than a non-destructive extraction method, such as vacuum-infiltration.

In instances where, the PMP includes a segment, portion, or extract of a plant EV, the EV segment, portion, or extract may have a mean surface area less than that of an intact vesicle, e.g., a mean surface area less than 77 nm², 100 nm², 1000 nm², 1×10⁴ nm², 1×10⁵ nm², 1×10⁶ nm², or 3.2×10⁶ nm²). In some instances, the EV segment, portion, or extract has a surface area of less than 70 nm², 60 nm², 50 nm², 40 nm², 30 nm², 20 nm², or 10 nm²). In some instances, the PMP may include a plant EV, or segment, portion, or extract thereof, that has a mean volume less than that of an intact vesicle, e.g., a mean volume of less than 65 nm³, 100 nm³, 1000 nm³, 1×10⁴ nm³, 1×10⁵ nm³, 1×10⁶ nm³, 1×10⁷ nm³, 1×10⁸ nm³, or 5.3×10⁸ nm³).

The PMPs in the plurality may include plant EV segments and/or plant EV-extracted lipids or a mixture thereof.

A. Production Methods

PMPs may be produced from plant EVs, or a segment, portion or extract (e.g., lipid extract) thereof, that occur naturally in plants, or parts thereof, including plant tissues or plant cells.

One exemplary method for producing PMPs includes (a) providing a pectin-rich preparation from a plant comprising extracellular vesicles (EVs), the preparation having a turbidity of 0.8 AU or greater at an absorbance of 650 nm; (b) treating the preparation to reduce the turbidity of the preparation or a fraction thereof; and (c) separating PMPs from the preparation or fraction thereof, thereby producing PMPs. In some examples, the turbidity of the preparation of step (a) is 0.5, 0.6, 0.7, 0.8, 0.81, 0.82, 0.83, 0.84, 0.85, 0.86, 0.87, 0.88, 0.89, 0.9, 1.0, 2.0, 3.0, or 4.0 AU or greater. In some examples, the turbidity of the preparation of step (a) is 0.86 or greater. In some examples, the preparation of step (a) has a percent light transmittance of 18% or lower, 17% or lower, 16% or lower, 15% or lower, 14% or lower, 13% or lower, 12% or lower, 11% or lower, 10% or lower, 9% or lower, 8% or lower, 7% or lower, 6% or lower, 5% or lower, 4% or lower, 3% or lower, 2% or lower, or 1% or lower at an absorbance of 650 nm.

A second exemplary method for producing PMPs includes (a) providing a pectin-rich preparation having a viscosity of at least 1.4 cP at 20° C. from a plant comprising EVs; (b) treating the preparation to reduce the viscosity of the preparation or a fraction thereof; and (c) separating PMPs from the preparation or fraction thereof, thereby producing PMPs.

A third exemplary method for producing PMPs includes (a) providing a pectin-rich preparation from a plant comprising EVs; (b) treating the preparation with an agent that reduces pectin gelation; (c) concentrating the preparation, wherein the viscosity of the concentrated preparation is reduced by at least 10% relative to a concentrated preparation that has not been treated with the agent that reduces pectin gelation; and (d) separating PMPs from the preparation or fraction thereof, thereby producing PMPs.

In some examples, the viscosity of the concentrated preparation is reduced by at least 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99%, or 100% relative to a concentrated preparation that has not been treated with the agent that reduces pectin gelation. Viscosity of the concentrated preparation may be measured during the concentration or after the concentration, e.g., 5 minutes, 10 minutes, 20 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, or more than 24 hours after the concentration.

The viscosity of the concentrated preparation that has not been treated with the agent that produces pectin gelation may be e.g., 1.4 cP when viscosity is measured at 20° C. In some examples, the viscosity of the concentrated preparation that has not been treated with the agent that produces pectin gelation is 1.01 cP, 1.1 cP, 1.2 cP, 1.3 cP, 1.4 cP, 1.5 cP, 1.6 cP, 1.7 cP, 1.8 cP, 1.9 cP, 2 cP, 3 cP, 4 cP, 5 cP, 6 cP, 7 cP, 8 cP, 9 cP, 10 cP, 20 cP, 50 cP, 100 cP, 250 cP, 500 cP, 750 cP, 1000 cP, 2000 cP, 5000 cP, 10,000 cP, 20,000 cP, 50,000 cP, 75,000 cP, or more than 75,000 cP at 20° C.

A fourth exemplary method for producing PMPs includes (a) providing a pectin-rich preparation from a plant comprising EVs; (b) treating the preparation to reduce high molecular weight pectin in the preparation or a fraction thereof; and (c) separating PMPs from the preparation or fraction thereof, thereby producing PMPs.

A fifth exemplary method for producing PMPs includes (a) providing a pectin-rich preparation from a plant comprising EVs; (b) contacting the preparation or a fraction thereof with a chelating agent; and (c) separating PMPs from the chelated preparation or fraction thereof, thereby producing PMPs.

A sixth exemplary method for producing PMPs includes (a) processing at least 500 g of a pectin-rich plant or plant part comprising EVs into a preparation; (b) contacting the preparation or a fraction thereof with a chelating agent; and (c) processing the chelated preparation or fraction thereof to separate PMPs, wherein the contacting is performed in an amount and for a time sufficient to reduce high molecular weight pectin in the chelated preparation or fraction thereof by at least 10%. The processing of step (c) may comprise separating the PMPs from the chelated preparation or fraction thereof.

In some examples of the fourth and fifth methods, the chelating agent reduces gelation of pectin in the chelated preparation or fraction thereof,

The chelating agent may be, e.g., ethylenediaminetetraacetic acid (EDTA) or ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetraacetic acid (EGTA). The chelating agent may act by chelating (e.g., binding to and diminishing the reactivity of) a metal ion, e.g., a calcium ion (e.g., Ca²⁺) in the plant preparation, and may diminish the reactivity of the metal ion in the solution by, e.g., at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or 100%. The reactivity of the metal ion in the solution may be quantified as esterification of pectins, e.g., in an assay for viscosity or turbidity of the solution. The chelating agent, e.g., EDTA or EGTA, may be formulated with a buffer, e.g., 2-(N-morpholino)ethanesulfonic acid (MES), tris(hydroxymethyl)aminomethane (Tris), or phosphate buffered saline (PBS). The chelating agent may be formulated with sodium hydroxide (NaOH).

The contacting of the preparation or fraction thereof with the chelating agent may be performed in an amount and for a time sufficient to reduce high molecular weight pectin in the chelated preparation or fraction thereof, e.g., reduce high molecular weight pectin by at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or 100%. The preparation may be contacted with the chelating agent for any suitable amount of time, e.g., 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 40 minutes, 50 minutes, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 3.5 hours, 4 hours, 4.5 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 10 hours, 11 hours, 12 hours, 24 hours, or more than 24 hours. The preparation or fraction thereof may be contacted with the chelating agent at any stage in the production process, e.g., contacted with the chelating agent at more than one stage in the production process.

Any one of the above-described methods may further comprise treating the plant preparation with a pectinase enzyme. The pectinase enzyme may be any enzyme or a mixture of enzymes capable of degrading a pectin (e.g., a high molecular weight pectin), e.g., a pectolyase (pectin lyase) enzyme or a polygalacturonase (pectin depolymerase) enzyme.

A seventh exemplary method for producing PMPs includes (a) providing a pectin-rich preparation from a plant comprising EVs; (b) contacting the preparation or a fraction thereof with a pectinase enzyme (e.g., an enzyme or a mixture of enzymes capable of degrading a pectin, e.g., a pectolyase enzyme or a polygalacturonase enzyme; and (c) separating PMPs from the preparation or fraction thereof, thereby producing PMPs.

The contacting of the preparation or fraction thereof with the pectinase enzyme may be performed in an amount and for a time sufficient to reduce high molecular weight pectin in the chelated preparation or fraction thereof, e.g., reduce high molecular weight pectin by at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or 100%. The preparation may be contacted with the pectinase enzyme for any suitable amount of time, e.g., 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 40 minutes, 50 minutes, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 3.5 hours, 4 hours, 4.5 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 10 hours, 11 hours, 12 hours, 24 hours, or more than 24 hours. The preparation or fraction thereof may be contacted with the pectinase enzyme at any stage in the production process, e.g., contacted with the pectinase enzyme at more than one stage in the production process.

The method may further involve removal or inactivation of the pectinase enzyme, e.g., inactivation of the pectinase enzyme by exposing the preparation to a temperature and for a time sufficient to deactivate the enzyme.

The PMPs provided herein can include a plant EV, or segment, portion, or extract thereof, isolated from a variety of plants or plant parts. The plant or plant part may be pectin-rich.

In some examples, the pectin-rich plant preparation derived from the plant part has a pectin concentration of at least 0.01%, e.g., has a pectin concentration of at least 0.02%, 0.04%, 0.06%, 0.08%, 0.1%, 0.2%, 0.4%, 0.6%, 0.8%, 1%, 2%, or more than 2%. In some examples, the pectin-rich plant preparation derived from the plant part has a pectin concentration of at least 0.1%. In some examples, the pectin concentration in the PMPs of step (c) is reduced by at least 1% relative to PMPs produced from a preparation that has not been treated, e.g., reduced by at least 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%. In some examples, the pectin concentration in the PMPs of step (c) is reduced by at least 10% relative to PMPs produced from a preparation that has not been treated.

In some examples, the pectin-rich plant preparation derived from the plant part has a viscosity of at least 1.01 cP at 20° C., e.g., has a viscosity of at least 1.01 cP, 1.02 cP, 1.03 cP, 1.04 cP, 1.05 cP, 1.1 cP, 1.2 cP, 1.3 cP, 1.4 cP, 1.5 cP, 2 cP, 3 cP, 4 cP, 5 cP, 6 cP, 7 cP, 8 cP, 9 cP, 10 cP, 20 cP, 50 cP, 100 cP, 250 cP, 500 cP, 750 cP, 1000 cP, 2000 cP, 5000 cP, 10,000 cP, 20,000 cP, 50,000 cP, 75,000 cP, or more than 75,000 cP at 20° C. In some examples, the pectin-rich plant preparation derived from the plant part has a viscosity of at least 1.4 cP.

In some examples, the viscosity of the preparation is reduced by at least 1% relative to a preparation that has not been treated (e.g., has not been treated to reduce viscosity, e.g., has not been treated with a chelating agent or a pectinase), e.g., is reduced by at least 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%. In some examples, the viscosity of the preparation is reduced by at least 5% relative to a preparation that has not been treated.

The viscosity of the preparation may be monitored. An exemplary method for producing PMPs includes (a) providing a pectin-rich preparation from a plant comprising EVs; (b) (i) treating the preparation to reduce the turbidity of the preparation or a fraction thereof; (ii) treating the preparation to reduce the viscosity of the preparation or a fraction thereof; (iii) treating the preparation to reduce high molecular weight pectin in the preparation or a fraction thereof; (iv) contacting the preparation or a fraction thereof with a chelating agent; or (v) contacting the preparation or a fraction thereof with a pectinase enzyme; (c) intermittently or continuously measuring the viscosity of the preparation or fraction thereof during step (b); (d) ending step (b) when the viscosity of the preparation or fraction thereof is below a predetermined level that informs that the preparation or fraction thereof of step (e) will have reduced gelation relative to a preparation or fraction thereof that has not been treated; and (e) separating PMPs from the preparation or fraction thereof.

Viscosity may be measured using any method known in the art, e.g., measured using a viscometer (e.g., a U-tube viscometer, a falling-sphere viscometer, a falling-piston viscometer, an oscillating-piston viscometer, a vibrational viscometer, a rotational viscometer, a bubble viscometer, or a rectangular slit viscometer) or a rheometer. Viscosity may be measured in-process (e.g., in-process during step (b) of the above-described method). Viscosity may be measured intermittently or continuously, e.g., continuously during all or a portion of step (b) of the above-described method.

The predetermined level of viscosity of step (d) may be, e.g., 1.4 cP when viscosity is measured at 20° C. In some examples, the predetermined level of viscosity of step (d) is 1.0 cP, 1.1 cP, 1.2 cP, 1.3 cP, 1.4 cP, 1.5 cP, 1.6 cP, 1.7 cP, 1.8 cP, 1.9 cP, 2 cP, 3 cP, 4 cP, 5 cP, 6 cP, 7 cP, 8 cP, 9 cP, 10 cP, 20 cP, 50 cP, 100 cP, 250 cP, 500 cP, 750 cP, 1000 cP, 2000 cP, 5000 cP, 10,000 cP, 20,000 cP, 50,000 cP, 75,000 cP, or more than 75,000 cP at 20° C.

The turbidity of the preparation may be monitored. An exemplary method for producing PMPs includes (a) providing a pectin-rich preparation from a plant comprising EVs; (b) (i) treating the preparation to reduce the turbidity of the preparation or a fraction thereof; (ii) treating the preparation to reduce the viscosity of the preparation or a fraction thereof; (iii) treating the preparation to reduce high molecular weight pectin in the preparation or a fraction thereof; (iv) contacting the preparation or a fraction thereof with a chelating agent; or (v) contacting the preparation or a fraction thereof with a pectinase enzyme; (c) intermittently or continuously measuring the turbidity of the preparation or fraction thereof during step (b); (d) ending step (b) when the turbidity of the preparation or fraction thereof is below a predetermined level that informs that the preparation or fraction thereof of step (e) will have reduced gelation relative to a preparation or fraction thereof that has not been treated; and (e) separating PMPs from the preparation or fraction thereof.

Turbidity may be measured using any method known in the art, e.g., measured based on absorbance of light (e.g., absorbance at 650 nm), light scattering (e.g., using a nephelometer), attenuation of a light beam (e.g., a Jackson Candle method), or visibility of a marker (e.g., a Secchi disk). Turbidity may be measured in-process (e.g., in-process during step (b) of the above-described method). Turbidity may be measured intermittently or continuously, e.g., continuously during all or a portion of step (b) of the above-described method. In some instances, turbidity is measured in a diluted sample.

The predetermined level of turbidity of step (d) may be, e.g., 0.8 arbitrary units (AU) absorbance as measured at 650 nm. In some examples, the predetermined level of turbidity of step (d) is 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, or 5.0 AU at an absorbance of 650 nm.

Upon isolating the plant EVs, thereby producing PMPs, the PMPs can be separated or collected into a crude PMP fraction. For instance, the separating step may involve separating the plurality of PMPs into a crude PMP fraction using centrifugation (e.g., differential centrifugation or ultracentrifugation) and/or filtration to separate the PMP-containing fraction from large contaminants, including plant tissue debris, plant cells, or plant cell organelles (e.g., nuclei or chloroplasts). As such, the crude PMP fraction will have a decreased number of large contaminants, including plant tissue debris, plant cells, or plant cell organelles (e.g., nuclei, mitochondria or chloroplasts), as compared to the initial sample from the source plant or plant part.

In some examples of the above methods, the separating or processing step involves centrifugation. The centrifugation may be differential centrifugation, e.g., differential centrifugation using a sucrose gradient. The centrifugation may be ultracentrifugation. The centrifugation step may separate the PMP-containing fraction from plant cells or cellular debris in the preparation or fraction thereof. In such instances, the PMP fraction will have a decreased number of plant cells or cellular debris, as compared to the initial preparation or fraction thereof.

In some examples of the above methods, the separating or processing step involves one or more filtration steps. The filtration may be tangential flow filtration. In some examples, the tangential flow filtration involves exchanging the volume of the preparation at least 2 times, e.g., exchanging the volume of the preparation at least 3 times, at least 4 times, at least 5 times, at least 6 times, at least 7 times, at least 8 times, at least 9 times, or at least 10 times. In some examples, the tangential flow filtration involves exchanging the volume of the preparation at least 10 times.

In some examples of the above methods, the separating or processing step involves size exclusion chromatography (SEC). In some examples, the SEC is performed using an SEC column that separates molecules having a size between 10 and 1000 nm, e.g., between 35 and 350 nm. In some examples, the SEC column has a resin pore size of at least 10 nm, 15 nm, 20 nm, 25 nm, 30 nm, 35 nm, 40 nm, 45 nm, 50 nm, 55 nm, 60 nm, 65 nm, 70 nm, 75 nm, or 80 nm, e.g., has a resin pore size of between 20 nm and 50 nm.

In some examples of the above methods, the separating or processing step involves one, two, or all three of centrifugation (e.g., differential centrifugation), tangential flow filtration, and size exclusion chromatography, e.g., involves centrifugation; involves tangential flow filtration; involves size exclusion chromatography; involves centrifugation and tangential flow filtration; involves centrifugation and size exclusion chromatography; involves tangential flow filtration and size exclusion chromatography; or involves centrifugation, tangential flow filtration, and size exclusion chromatography.

The separating or processing step of the method may comprise one or more of a wash step, dilution, pH modification, dialysis, and removal of contaminants.

The plant preparation or fraction thereof or the PMP fraction may be further purified by additional purification methods to produce a plurality of pure PMPs. For example, the crude PMP fraction can be separated from other plant components by ultracentrifugation, e.g., using a density gradient (iodixanol or sucrose) and/or use of other approaches to remove aggregated components (e.g., precipitation or size-exclusion chromatography). The resulting pure PMPs may have a decreased level of contaminants or undesired components from the source plant (e.g., one or more non-PMP components, such as protein aggregates, nucleic acid aggregates, protein-nucleic acid aggregates, free lipoproteins, lipido-proteic structures), nuclei, cell wall components, cell organelles, or a combination thereof) relative to one or more fractions generated during the earlier separation steps, or relative to a pre-established threshold level, e.g., a commercial release specification. For example, the pure PMPs may have a decreased level (e.g., by about 5%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%; or by about 2× fold, 4× fold, 5× fold, 10× fold, 20× fold, 25× fold, 50× fold, 75× fold, 100× fold, or more than 100× fold) of plant organelles or cell wall components relative to the level in the initial sample. In some instances, the pure PMPs are substantially free (e.g., have undetectable levels) of one or more non-PMP components, such as protein aggregates, nucleic acid aggregates, protein-nucleic acid aggregates, free lipoproteins, lipido-proteic structures), nuclei, cell wall components, cell organelles, or a combination thereof. Further examples of the releasing and separation steps can be found in Example 1. The PMPs may be at a concentration of, e.g., 1×10⁹, 5×10⁹, 1×10¹⁰, 5×10¹⁰, 5×10¹⁰, 1×10¹¹, 2×10¹¹, 3×10¹¹, 4×10¹¹, 5×10¹¹, 6×10¹¹, 7×10¹¹, 8×10¹¹, 9×10¹¹, 1×10¹², 2×10¹², 3×10¹², 4×10¹², 5×10¹², 6×10¹², 7×10¹², 8×10¹², 9×10¹², 1×10¹³, or more than 1×10¹³ PMPs/mL.

For example, protein aggregates may be removed from isolated PMPs. For example, the isolated PMP solution can be taken through a range of pHs (e.g., as measured using a pH probe) to precipitate out protein aggregates in solution. The pH can be adjusted to, e.g., pH 3, pH 5, pH 7, pH 9, or pH 11 with the addition of, e.g., sodium hydroxide or hydrochloric acid. Once the solution is at the specified pH, it can be filtered to remove particulates. Alternatively, the isolated PMP solution can be flocculated using the addition of charged polymers, such as Polymin-P or Praestol 2640. Briefly, Polymin-P or Praestol 2640 is added to the solution and mixed with an impeller. The solution can then be filtered to remove particulates. Alternatively, aggregates can be solubilized by increasing salt concentration. For example NaCl can be added to the isolated PMP solution until it is at, e.g., 1 mol/L. The solution can then be filtered to isolate the PMPs. Alternatively, aggregates are solubilized by increasing the temperature. For example, the isolated PMPs can be heated under mixing until the solution has reached a uniform temperature of, e.g., 50° C. for 5 minutes. The PMP mixture can then be filtered to isolate the PMPs. Alternatively, soluble contaminants from PMP solutions can be separated by size-exclusion chromatography column according to standard procedures, where PMPs elute in the first fractions, whereas proteins and ribonucleoproteins and some lipoproteins are eluted later. The efficiency of protein aggregate removal can be determined by measuring and comparing the protein concentration before and after removal of protein aggregates via BCA/Bradford protein quantification.

Any of the production methods described herein can be supplemented with any quantitative or qualitative methods known in the art to characterize or identify the PMPs at any step of the production process. PMPs may be characterized by a variety of analysis methods to estimate PMP yield, PMP concentration, PMP purity, PMP composition, or PMP sizes. PMPs can be evaluated by a number of methods known in the art that enable visualization, quantitation, or qualitative characterization (e.g., identification of the composition) of the PMPs, such as microscopy (e.g., transmission electron microscopy), dynamic light scattering, nanoparticle tracking, spectroscopy (e.g., Fourier transform infrared analysis), or mass spectrometry (protein and lipid analysis). In certain instances, methods (e.g., mass spectroscopy) may be used to identify plant EV markers present on the PMP, such as markers disclosed in the Appendix. To aid in analysis and characterization, of the PMP fraction, the PMPs can additionally be labelled or stained. For example, the PMPs can be stained with 3,3′-dihexyloxacarbocyanine iodide (DIOC₆), a fluorescent lipophilic dye, PKH67 (Sigma Aldrich); Alexa Fluor® 488 (Thermo Fisher Scientific), or DyLight™ 800 (Thermo Fisher). In the absence of sophisticated forms of nanoparticle tracking, this relatively simple approach quantifies the total membrane content and can be used to indirectly measure the concentration of PMPs (Rutter and Innes, Plant Physiol. 173(1): 728-741, 2017; Rutter et al, Bio. Protoc. 7(17): e2533, 2017). For more precise measurements, and to assess the size distributions of PMPs, nanoparticle tracking can be used.

In some examples of any of the above methods, the PMPs of step (c) may be concentrated at least 2× relative to the preparation of step (a) or relative to a control sample, e.g., are concentrated at least 3×, 4×, 5×, 6×, 7×, 8×, 9×, 10×, 11×, 12×, 13×, 14×, 15×, 16×, 17×, 18×, 19×, 20×, 25×, 50×, 75×, or more than 100×. In some examples of any of the above methods, the PMPs of step (c) are concentrated at least 10× relative to the preparation of step (a). The PMPs in the composition may be at a concentration of at least 1, 10, 50, 100, 250, 500, or 750 μg PMP protein/ml, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, or 10 mg PMP protein/ml.

The isolated PMPs may make up about 0.1% to about 100% of the composition, such as any one of about 0.01% to about 100%, about 1% to about 99.9%, about 0.1% to about 10%, about 1% to about 25%, about 10% to about 50%, about 50% to about 99%, or about 75% to about 100%. In some instances, the composition includes at least any of 0.1%, 0.5%, 1%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or more PMPs, e.g., as measured by wt/vol, percent PMP protein composition, and/or percent lipid composition (e.g., by measuring fluorescently labelled lipids); See, e.g., Example 3). In some instances, the concentrated agents are used as commercial products, e.g., the final user may use diluted agents, which have a substantially lower concentration of active ingredient. In some embodiments, the composition is formulated as a pest control concentrate formulation, e.g., an ultra-low-volume concentrate formulation.

Providing the pectin-rich plant preparation may comprise processing a plant or a plant part (e.g., a pectin-rich plant or pectin-rich plant part) to release EVs, thereby producing PMPs. For example, the processing may include or consist of blending a plant part, mashing a plant or plant part through a strainer, or cold pressing a plant or plant part.

PMPs can be produced from a plant, or part thereof, by a variety of methods. Any method that allows release of the EV-containing apoplastic fraction of a plant, or an otherwise extracellular fraction that contains PMPs comprising secreted EVs (e.g., cell culture media) is suitable in the present methods. EVs can be separated from the plant or plant part by either destructive (e.g., grinding or blending of a plant, or any plant part) or non-destructive (washing or vacuum infiltration of a plant or any plant part) methods. For instance, the plant, or part thereof, can be vacuum-infiltrated, ground, blended, or a combination thereof to isolate EVs from the plant or plant part, thereby producing PMPs. For instance, the isolating step may involve (b) isolating a crude PMP fraction from the initial sample (e.g., a plant, a plant part, or a sample derived from a plant or plant part), wherein the isolating step involves vacuum infiltrating the plant (e.g., with a vesicle isolation buffer) to release and collect the apoplastic fraction. Alternatively, the isolating step may involve grinding or blending the plant to release the EVs, thereby producing PMPs.

As illustrated by Example 1, PMPs can be produced from a variety of plants, or parts thereof (e.g., the leaf apoplast, seed apoplast, root, fruit, vegetable, pollen, phloem, or xylem sap). For example, PMPs can be isolated from the apoplastic fraction of a plant, such as the apoplast of a leaf (e.g., apoplast Arabidopsis thaliana leaves) or the apoplast of seeds (e.g., apoplast of sunflower seeds). Other exemplary PMPs are produced from roots (e.g., ginger roots), fruit juice (e.g., grapefruit juice), vegetables (e.g., broccoli), pollen (e.g., olive pollen), phloem sap (e.g., Arabidopsis phloem sap), xylem sap (e.g., tomato plant xylem sap), or cell culture supernatant (e.g. BY2 tobacco cell culture supernatant). In other examples, PMPs are produced from a citrus plant, e.g., a grapefruit or a lemon, or a juice sac of a citrus plant, e.g., a juice sac of a grapefruit or a lemon. In other examples, PMPs are produced from a flowering plant such as a pomegranate, a blueberry, duckweed (e.g., Wolffia globosa), broccoli, avocado, grape, tomato fruit, or onion.

PMPs may be isolated from any genera of plants (vascular or nonvascular), including but not limited to angiosperms (monocotyledonous and dicotyledonous plants), gymnosperms, ferns, selaginellas, horsetails, psilophytes, lycophytes, algae (e.g., unicellular or multicellular, e.g., archaeplastida), or bryophytes. In certain instances, PMPs can be produced from a vascular plant, for example monocotyledons or dicotyledons or gymnosperms. For example, PMPs can be produced from alfalfa, apple, Arabidopsis, banana, barley, canola, castor bean, chicory, chrysanthemum, clover, cocoa, coffee, cotton, cottonseed, corn, crambe, cranberry, cucumber, dendrobium, dioscorea, eucalyptus, fescue, flax, gladiolus, liliacea, linseed, millet, muskmelon, mustard, oat, oil palm, oilseed rape, papaya, peanut, pineapple, ornamental plants, Phaseolus, potato, rapeseed, rice, rye, ryegrass, safflower, sesame, sorghum, soybean, sugarbeet, sugarcane, sunflower, strawberry, tobacco, tomato, turfgrass, wheat or vegetable crops such as lettuce, celery, broccoli, cauliflower, cucurbits; fruit and nut trees, such as apple, pear, peach, orange, grapefruit, lemon, lime, almond, pecan, walnut, hazel; vines, such as grapes, kiwi, hops; fruit shrubs and brambles, such as raspberry, blackberry, gooseberry; forest trees, such as ash, pine, fir, maple, oak, chestnut, popular; with alfalfa, canola, castor bean, corn, cotton, crambe, flax, linseed, mustard, oil palm, oilseed rape, peanut, potato, rice, safflower, sesame, soybean, sugarbeet, sunflower, tobacco, tomato, or wheat.

PMPs may be produced from a whole plant (e.g., a whole rosettes or seedlings) or alternatively from one or more plant parts (e.g., a pectin-rich plant part, e.g., a leaf, seed, root, fruit, vegetable, pollen, phloem sap, or xylem sap). For example, PMPs can be produced from shoot vegetative organs/structures (e.g., leaves, stems, or tubers), roots, flowers and floral organs/structures (e.g., pollen, bracts, sepals, petals, stamens, carpels, anthers, or ovules), seed (including embryo, endosperm, or seed coat), fruit (the mature ovary), sap (e.g., phloem or xylem sap), plant tissue (e.g., vascular tissue, ground tissue, tumor tissue, or the like), and cells (e.g., single cells, protoplasts, embryos, callus tissue, guard cells, egg cells, or the like), or progeny of same. For instance, the isolation step may involve (a) providing a plant, or a part thereof. In some examples, the plant part is an Arabidopsis leaf. The plant may be at any stage of development. For example, the PMP can be produced from seedlings, e.g., 1 week, 2 week, 3 week, 4 week, 5 week, 6 week, 7 week, or 8 week old seedlings (e.g., Arabidopsis seedlings). Other exemplary PMPs can include PMPs produced from roots (e.g., ginger roots), fruit juice (e.g., grapefruit juice), vegetables (e.g., broccoli), pollen (e.g., olive pollen), phloem sap (e.g., Arabidopsis phloem sap), or xylem sap (e.g., tomato plant xylem sap).

PMPs may be produced from plant cultures, e.g., a plant cell culture or tissue culture or a culture comprising entire plants or plant parts (e.g., a hydroponic culture). As used herein, the term “plant culture” refers to a plurality of plant cells, plant parts, plants (e.g., entire plants), or plant tissue that is propagated in or on a liquid, gel, semi-solid, or solid medium. Plant cultures include, but are not limited to, cultures of naturally occurring plants, plant parts, plant cells, or plant tissue or genetically modified plants, plant parts, plant cells, or plant tissues.

As illustrated by Example 2, PMPs can be purified by a variety of methods, for example, by using a density gradient (iodixanol or sucrose) in conjunction with ultracentrifugation and/or methods to remove aggregated contaminants, e.g., precipitation or size-exclusion chromatography. For instance, Example 2 illustrates purification of PMPs that have been obtained via the separation steps outlined in Example 1. Further, PMPs can be characterized in accordance with the methods illustrated in Example 3.

In some instances, the PMPs of the present compositions and methods can be isolated from a plant, or part thereof, and used without further modification to the PMP. In other instances, the PMP can be modified prior to use, as outlined further herein.

B. Plant EV Markers

The PMPs of the present compositions and methods may have a range of markers that identify the PMP as being produced from a plant EV, and/or including a segment, portion, or extract thereof. As used herein, the term “plant EV marker” refers to a component that is naturally associated with a plant and incorporated into or onto the plant EV in planta, such as a plant protein, a plant nucleic acid, a plant small molecule, a plant lipid, or a combination thereof. Examples of plant EV markers can be found, for example, in Rutter and Innes, Plant Physiol. 173(1): 728-741, 2017; Raimondo et al., Oncotarget. 6(23): 19514, 2015; Ju et al., Mol. Therapy. 21(7):1345-1357, 2013; Wang et al., Molecular Therapy. 22(3): 522-534, 2014; and Regente et al, J of Exp. Biol. 68(20): 5485-5496, 2017; each of which is incorporated herein by reference. Additional examples of plant EV markers are listed in the Appendix, and are further outlined herein.

The plant EV marker can include a plant lipid. Examples of plant lipid markers that may be found in the PMP include phytosterol, campesterol, β-sitosterol, stigmasterol, avenasterol, glycosyl inositol phosphoryl ceramides (GIPCs), glycolipids (e.g., monogalactosyldiacylglycerol (MGDG) or digalactosyldiacylglycerol (DGDG)), or a combination thereof. For instance, the PMP may include GIPCs, which represent the main sphingolipid class in plants and are one of the most abundant membrane lipids in plants. Other plant EV markers may include lipids that accumulate in plants in response to abiotic or biotic stressors (e.g., bacterial or fungal infection), such as phosphatidic acid (PA) or phosphatidylinositol-4-phosphate (PI4P).

Alternatively, the plant EV marker may include a plant protein. In some instances, the protein plant EV marker may be an antimicrobial protein naturally produced by plants, including defense proteins that plants secrete in response to abiotic or biotic stressors (e.g., bacterial or fungal infection). Plant pathogen defense proteins include soluble N-ethylmalemide-sensitive factor association protein receptor protein (SNARE) proteins (e.g., Syntaxin-121 (SYP121; GenBank Accession No.: NP_187788.1 or NP_974288.1), Penetration1 (PEN1; GenBank Accession No: NP_567462.1)) or ABC transporter Penetration3 (PEN3; GenBank Accession No: NP_191283.2). Other examples of plant EV markers includes proteins that facilitate the long-distance transport of RNA in plants, including phloem proteins (e.g., Phloem protein2-A1 (PP2-A1), GenBank Accession No: NP_193719.1), calcium-dependent lipid-binding proteins, or lectins (e.g., Jacalin-related lectins, e.g., Helianthus annuus jacalin (Helja; GenBank: AHZ86978.1). For example, the RNA binding protein may be Glycine-Rich RNA Binding Protein-7 (GRP7; GenBank Accession Number: NP_179760.1). Additionally, proteins that regulate plasmodesmata function can in some instances be found in plant EVs, including proteins such as Synap-Totgamin A A (GenBank Accession No: NP_565495.1). In some instances, the plant EV marker can include a protein involved in lipid metabolism, such as phospholipase C or phospholipase D. In some instances, the plant protein EV marker is a cellular trafficking protein in plants. In certain instances where the plant EV marker is a protein, the protein marker may lack a signal peptide that is typically associated with secreted proteins. Unconventional secretory proteins seem to share several common features like (i) lack of a leader sequence, (ii) absence of PTMs specific for ER or Golgi apparatus, and/or (iii) secretion not affected by brefeldin A which blocks the classical ER/Golgi-dependent secretion pathway. One skilled in the art can use a variety of tools freely accessible to the public (e.g., SecretomeP Database; SUBA3 (SUBcellular localization database for Arabidopsis proteins)) to evaluate a protein for a signal sequence, or lack thereof.

In instances where the plant EV marker is a protein, the protein may have an amino acid sequence having at least 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to a plant EV marker, such as any of the plant EV markers listed in the Appendix. For example, the protein may have an amino acid sequence having at least 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to PEN1 from Arabidopsis thaliana (GenBank Accession Number: NP_567462.1).

In some instances, the plant EV marker includes a nucleic acid encoded in plants, e.g., a plant RNA, a plant DNA, or a plant PNA. For example, the PMP may include dsRNA, mRNA, a viral RNA, a microRNA (miRNA), or a small interfering RNA (siRNA) encoded by a plant. In some instances, the nucleic acid may be one that is associated with a protein that facilitates the long-distance transport of RNA in plants, as discussed herein. In some instances, the nucleic acid plant EV marker may be one involved in host-induced gene silencing (HIGS), which is the process by which plants silence foreign transcripts of plant pests (e.g., pathogens such as fungi). For example, the nucleic acid may be one that silences bacterial or fungal genes. In some instances, the nucleic acid may be a microRNA, such as miR159 or miR166, which target genes in a fungal pathogen (e.g., Verticillium dahliae). In some instances, the protein may be one involved in carrying plant defense compounds, such as proteins involved in glucosinolate (GSL) transport and metabolism, including Glucosinolate Transporter-1-1 (GTR1; GenBankAccesion No: NP_566896.2), Glucosinolate Transporter-2 (GTR2; NP_201074.1), or Epithiospecific Modifier 1 (ESM1; NP_188037.1).

In instances where the plant EV marker is a nucleic acid, the nucleic acid may have a nucleotide sequence having at least 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to a plant EV marker, e.g., such as those encoding the plant EV markers listed in the Appendix. For example, the nucleic acid may have a polynucleotide sequence having at least 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99%, or 100% sequence identity to miR159 or miR166.

In some instances, the plant EV marker includes a compound produced by plants. For example, the compound may be a defense compound produced in response to abiotic or biotic stressors, such as secondary metabolites. One such secondary metabolite that be found in PMPs are glucosinolates (GSLs), which are nitrogen and sulfur-containing secondary metabolites found mainly in Brassicaceae plants. Other secondary metabolites may include allelochemicals.

In some instances, the PMP may also be identified as being produced from a plant EV based on the lack of certain markers (e.g., lipids, polypeptides, or polynucleotides) that are not typically produced by plants, but are generally associated with other organisms (e.g., markers of animal EVs, bacterial EVs, or fungal EVs). For example, in some instances, the PMP lacks lipids typically found in animal EVs, bacterial EVs, or fungal EVs. In some instances, the PMP lacks lipids typical of animal EVs (e.g., sphingomyelin). In some instances, the PMP does not contain lipids typical of bacterial EVs or bacterial membranes (e.g., LPS). In some instances, the PMP lacks lipids typical of fungal membranes (e.g., ergosterol).

Plant EV markers can be identified using any approaches known in the art that enable identification of small molecules (e.g., mass spectroscopy, mass spectrometry), lipds (e.g., mass spectroscopy, mass spectrometry), proteins (e.g., mass spectroscopy, immunoblotting), or nucleic acids (e.g., PCR analysis). In some instances, a PMP composition described herein includes a detectable amount, e.g., a pre-determined threshold amount, of a plant EV marker described herein.

C. Loading of Agents

PMPs manufactured in accordance with the methods herein can be modified to include a heterologous functional agent (e.g., a heterologous agricultural agent (e.g., pesticidal agent, fertilizing agent, herbicidal agent, plant-modifying agent) or a heterologous therapeutic agent (e.g., a pathogen control agent such as an antifungal agent, an antibacterial agent, a virucidal agent, an anti-viral agent, an insecticidal agent, a nematicidal agent, an antiparasitic agent, or an insect repellent)), such as those described herein. The PMPs can carry or associate with such agents in a variety of ways to enable delivery of the agent to a target organism, e.g., by encapsulating the agent, incorporation of the component in the lipid bilayer structure, or association of the component (e.g., by conjugation) with the surface of the lipid bilayer structure of the PMP.

The heterologous functional agent can be incorporated or loaded into or onto the PMP by any methods known in the art that allow association, directly or indirectly, between the PMP and agent. Heterologous functional agent agents can be incorporated into the PMP by an in vivo method (e.g., in planta, e.g., through production of PMPs from a transgenic plant that comprises the heterologous agent), or in vitro (e.g., in tissue culture, or in cell culture), or both in vivo and in vitro methods.

In instances where the PMPs are loaded with a heterologous functional agent in vivo, the PMP may be produced from an EV, or segment, portion, or extract thereof, that has been loaded in planta, in tissue culture, or in cell culture. In planta methods include expression of the heterologous functional agent in a plant that has been genetically modified to express the heterologous functional agent. In some instances, the heterologous functional agent is exogenous to the plant. Alternatively, the heterologous functional agent may be naturally found in the plant, but expressed at an elevated level relative to that found in a non-genetically modified plant.

In some instances, the PMP can be loaded in vitro. The heterologous functional agent may be loaded onto or into (e.g., may be encapsulated by) the PMPs using, but not limited to, physical, chemical, and/or biological methods. For example, the heterologous functional agent may be introduced into PMP by one or more of electroporation, sonication, passive diffusion, stirring, lipid extraction, or extrusion. Loaded PMPs can be assessed to confirm the presence or level of the loaded agent using a variety methods, such as HPLC (e.g., to assess small molecules); immunoblotting (e.g., to assess proteins); and quantitative PCR (e.g., to assess nucleotides). However, it should be appreciated by those skilled in the art that the loading of a substance of interest into PMPs is not limited to the above-illustrated methods.

In some instances, the heterologous functional agent can be conjugated to the PMP, e.g., connected or joined, indirectly or directly, to the PMP. For instance, one or more pesticidal agents can be chemically linked to a PMP, such that the one or more pesticidal agents are joined (e.g., by covalent or ionic bonds) directly to the lipid bilayer of the PMP. In some instances, the conjugation of the heterologous functional agent to the PMPs can be achieved by first mixing the one or more heterologous functional agents with an appropriate cross-linking agent (e.g., N-ethylcarbo-diimide (“EDC”), which is generally utilized as a carboxyl activating agent for amide bonding with primary amines and also reacts with phosphate groups) in a suitable solvent. After a period of incubation sufficient to allow the heterologous functional agent to attach to the cross-linking agent, the cross-linking agent/heterologous functional agent mixture can then be combined with the PMPs and, after another period of incubation, subjected to a sucrose gradient (e.g., and 8, 30, 45, and 60% sucrose gradient) to separate the free heterologous functional agent and free PMPs from the heterologous functional agent conjugated to the PMPs. As part of combining the mixture with a sucrose gradient, and an accompanying centrifugation step, the PMPs conjugated to the heterologous functional agent are then seen as a band in the sucrose gradient, such that the conjugated PMPs can then be collected, washed, and dissolved in a suitable solution for use as described herein.

In some instances, the PMP is stably associated with the heterologous functional agent prior to and following delivery of the PMP, e.g., to a plant or to a pest. In other instances, the PMP is associated with the heterologous functional agent such that the heterologous functional agent becomes dissociated from the PMP following delivery of the PMP, e.g., to a plant or to a pest.

The PMP can be further modified with other components (e.g., lipids, e.g., sterols, e.g., cholesterol; or small molecules) to further alter the functional and structural characteristics of the PMP. For example, the PMPs can be further modified with stabilizing molecules that increase the stability of the PMP (e.g., for at least one day at room temperature, and/or stable for at least one week at 4° C.).

The PMPs can be loaded with various concentrations of the heterologous functional agent, depending on the particular agent or use. For example, in some instances, the PMPs are loaded such that the composition disclosed herein includes about 0.001, 0.01, 0.1, 1.0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, or 95 (or any range between about 0.001 and 95) or more wt % of a heterologous functional agent. In some instances, the PMPs are loaded such that the composition includes about 95, 90, 80, 70, 60, 50, 40, 30, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1.0, 0.1, 0.01, 0.001 (or any range between about 95 and 0.001) or less wt % of a heterologous functional agent. For example, the pest control (e.g., biopesticide or biorepellent) composition can include about 0.001 to about 0.01 wt %, about 0.01 to about 0.1 wt %, about 0.1 to about 1 wt %, about 1 to about 5 wt %, or about 5 to about 10 wt %, about 10 to about 20 wt % of the heterologous functional agent. In some instances, the PMP can be loaded with about 1, 5, 10, 50, 100, 200, or 500, 1,000, 2,000 (or any range between about 1 and 2,000) or more μg/ml of a heterologous functional agent. A liposome of the invention can be loaded with about 2,000, 1,000, 500, 200, 100, 50, 10, 5, 1 (or any range between about 2,000 and 1) or less μg/ml of a heterologous functional agent.

In some instances, the PMPs are loaded such that the composition disclosed herein includes at least 0.001 wt %, at least 0.01 wt %, at least 0.1 wt %, at least 1.0 wt %, at least 2 wt %, at least 3 wt %, at least 4 wt %, at least 5 wt %, at least 6 wt %, at least 7 wt %, at least 8 wt %, at least 9 wt %, at least 10 wt %, at least 15 wt %, at least 20 wt %, at least 30 wt %, at least 40 wt %, at least 50 wt %, at least 60 wt %, at least 70 wt %, at least 80 wt %, at least 90 wt %, or at least 95 wt % of a heterologous functional agent. In some instances, the PMP can be loaded with at least 1 μg/ml, at least 5 μg/ml, at least 10 μg/ml, at least 50 μg/ml, at least 100 μg/ml, at least 200 μg/ml, at least 500 μg/ml, at least 1,000 μg/ml, at least 2,000 μg/ml of a heterologous functional agent.

Examples of particular agents that can be loaded into the PMP are further outlined in the section entitled “Heterologous Functional Agents.”

D. Pharmaceutical Formulations

Included herein are compositions that can be formulated into pharmaceutical compositions, e.g., for administration to an animal, such as a human or a non-human agricultural animal (e.g., a cow, steer, pig, chicken, or turkey). The pharmaceutical composition may be administered to an animal with a pharmaceutically acceptable diluent, carrier, and/or excipient. Depending on the mode of administration and the dosage, the pharmaceutical composition of the methods described herein will be formulated into suitable pharmaceutical compositions to permit facile delivery. The single dose may be in a unit dose form as needed.

A pharmaceutical composition may be formulated for e.g., oral administration, intravenous administration (e.g., injection or infusion), or subcutaneous administration to an animal. For injectable formulations, various effective pharmaceutical carriers are known in the art (See, e.g., Remington: The Science and Practice of Pharmacy, 22^nd ed., (2012) and ASHP Handbook on Injectable Drugs, 18^th ed., (2014)).

Pharmaceutically acceptable carriers and excipients in the present compositions are nontoxic to recipients at the dosages and concentrations employed. Acceptable carriers and excipients may include buffers such as phosphate, citrate, HEPES, and TAE, antioxidants such as ascorbic acid and methionine, preservatives such as hexamethonium chloride, octadecyldimethylbenzyl ammonium chloride, resorcinol, and benzalkonium chloride, proteins such as human serum albumin, gelatin, dextran, and immunoglobulins, hydrophilic polymers such as polyvinylpyrrolidone, amino acids such as glycine, glutamine, histidine, and lysine, and carbohydrates such as glucose, mannose, sucrose, and sorbitol. The compositions may be formulated according to conventional pharmaceutical practice. The concentration of the compound in the formulation will vary depending upon a number of factors, including the dosage of the active agent (e.g., PMP) to be administered, and the route of administration.

For oral administration to an animal, the pharmaceutical composition can be prepared in the form of an oral formulation. Formulations for oral use can include tablets, caplets, capsules, syrups, or oral liquid dosage forms containing the active ingredient(s) in a mixture with non-toxic pharmaceutically acceptable excipients. These excipients may be, for example, inert diluents or fillers (e.g., sucrose, sorbitol, sugar, mannitol, microcrystalline cellulose, starches including potato starch, calcium carbonate, sodium chloride, lactose, calcium phosphate, calcium sulfate, or sodium phosphate); granulating and disintegrating agents (e.g., cellulose derivatives including microcrystalline cellulose, starches including potato starch, croscarmellose sodium, alginates, or alginic acid); binding agents (e.g., sucrose, glucose, sorbitol, acacia, alginic acid, sodium alginate, gelatin, starch, pregelatinized starch, microcrystalline cellulose, magnesium aluminum silicate, carboxymethylcellulose sodium, methylcellulose, hydroxypropyl methylcellulose, ethylcellulose, polyvinylpyrrolidone, or polyethylene glycol); and lubricating agents, glidants, and antiadhesives (e.g., magnesium stearate, zinc stearate, stearic acid, silicas, hydrogenated vegetable oils, or talc). Other pharmaceutically acceptable excipients can be colorants, flavoring agents, plasticizers, humectants, buffering agents, and the like. Formulations for oral use may also be provided in unit dosage form as chewable tablets, non-chewable tablets, caplets, capsules (e.g., as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium). The compositions disclosed herein may also further include an immediate-release, extended release or delayed-release formulation.

For parenteral administration to an animal, the pharmaceutical compositions may be formulated in the form of liquid solutions or suspensions and administered by a parenteral route (e.g., subcutaneous, intravenous, or intramuscular). The pharmaceutical composition can be formulated for injection or infusion. Pharmaceutical compositions for parenteral administration can be formulated using a sterile solution or any pharmaceutically acceptable liquid as a vehicle. Pharmaceutically acceptable vehicles include, but are not limited to, sterile water, physiological saline, or cell culture media (e.g., Dulbecco's Modified Eagle Medium (DMEM), α-Modified Eagles Medium (α-MEM), F-12 medium). Formulation methods are known in the art, see e.g., Gibson (ed.) Pharmaceutical Preformulation and Formulation (2nd ed.) Taylor & Francis Group, CRC Press (2009).

E. Agricultural Formulations

To allow ease of application, handling, transportation, storage, and activity, the active agent, here PMPs, can be formulated with other substances. PMPs can be formulated into, for example, baits, concentrated emulsions, dusts, emulsifiable concentrates, fumigants, gels, granules, microencapsulations, seed treatments, suspension concentrates, suspoemulsions, tablets, water soluble liquids, water dispersible granules or dry flowables, wettable powders, and ultra-low volume solutions. For further information on formulation types see “Catalogue of Pesticide Formulation Types and International Coding System” Technical Monograph n° 2, 5th Edition by CropLife International (2002).

Active agents (e.g., PMPs, additional pesticides) can be applied as aqueous suspensions or emulsions prepared from concentrated formulations of such agents. Such water-soluble, water-suspendable, or emulsifiable formulations are either solids, usually known as wettable powders, or water dispersible granules, or liquids usually known as emulsifiable concentrates, or aqueous suspensions. Wettable powders, which may be compacted to form water dispersible granules, comprise an intimate mixture of the pesticide, a carrier, and surfactants. The carrier is usually selected from among the attapulgite clays, the montmorillonite clays, the diatomaceous earths, or the purified silicates. Effective surfactants, including from about 0.5% to about 10% of the wettable powder, are found among sulfonated lignins, condensed naphthalenesulfonates, naphthalenesulfonates, alkylbenzenesulfonates, alkyl sulfates, and non-ionic surfactants such as ethylene oxide adducts of alkyl phenols.

Emulsifiable concentrates can comprise a suitable concentration of PMPs, such as from about 50 to about 500 grams per liter of liquid dissolved in a carrier that is either a water miscible solvent or a mixture of water-immiscible organic solvent and emulsifiers. Useful organic solvents include aromatics, especially xylenes and petroleum fractions, especially the high-boiling naphthalenic and olefinic portions of petroleum such as heavy aromatic naphtha. Other organic solvents may also be used, such as the terpenic solvents including rosin derivatives, aliphatic ketones such as cyclohexanone, and complex alcohols such as 2-ethoxyethanol. Suitable emulsifiers for emulsifiable concentrates are selected from conventional anionic and non-ionic surfactants.

Aqueous suspensions comprise suspensions of water-insoluble pesticides dispersed in an aqueous carrier at a concentration in the range from about 5% to about 50% by weight. Suspensions are prepared by finely grinding the pesticide and vigorously mixing it into a carrier comprised of water and surfactants. Ingredients, such as inorganic salts and synthetic or natural gums may also be added, to increase the density and viscosity of the aqueous carrier.

PMPs may also be applied as granular compositions that are particularly useful for applications to the soil. Granular compositions usually contain from about 0.5% to about 10% by weight of the pesticide, dispersed in a carrier that comprises clay or a similar substance. Such compositions are usually prepared by dissolving the formulation in a suitable solvent and applying it to a granular carrier which has been pre-formed to the appropriate particle size, in the range of from about 0.5 to about 3 mm. Such compositions may also be formulated by making a dough or paste of the carrier and compound and crushing and drying to obtain the desired granular particle size.

Dusts containing the present PMP formulation are prepared by intimately mixing PMPs in powdered form with a suitable dusty agricultural carrier, such as kaolin clay, ground volcanic rock, and the like. Dusts can suitably contain from about 1% to about 10% of the packets. They can be applied as a seed dressing or as a foliage application with a dust blower machine.

It is equally practical to apply the present formulation in the form of a solution in an appropriate organic solvent, usually petroleum oil, such as the spray oils, which are widely used in agricultural chemistry.

PMPs can also be applied in the form of an aerosol composition. In such compositions the packets are dissolved or dispersed in a carrier, which is a pressure-generating propellant mixture. The aerosol composition is packaged in a container from which the mixture is dispensed through an atomizing valve.

Another embodiment is an oil-in-water emulsion, wherein the emulsion comprises oily globules which are each provided with a lamellar liquid crystal coating and are dispersed in an aqueous phase, wherein each oily globule comprises at least one compound which is agriculturally active, and is individually coated with a monolamellar or oligolamellar layer including: (1) at least one non-ionic lipophilic surface-active agent, (2) at least one non-ionic hydrophilic surface-active agent and (3) at least one ionic surface-active agent, wherein the globules having a mean particle diameter of less than 800 nanometers. Further information on the embodiment is disclosed in U.S. patent publication 20070027034 published Feb. 1, 2007. For ease of use, this embodiment will be referred to as “OIWE.”

Additionally, generally, when the molecules disclosed above are used in a formulation, such formulation can also contain other components. These components include, but are not limited to, (this is a non-exhaustive and non-mutually exclusive list) wetters, spreaders, stickers, penetrants, buffers, sequestering agents, drift reduction agents, compatibility agents, anti-foam agents, cleaning agents, and emulsifiers. A few components are described forthwith.

A wetting agent is a substance that when added to a liquid increases the spreading or penetration power of the liquid by reducing the interfacial tension between the liquid and the surface on which it is spreading. Wetting agents are used for two main functions in agrochemical formulations: during processing and manufacture to increase the rate of wetting of powders in water to make concentrates for soluble liquids or suspension concentrates; and during mixing of a product with water in a spray tank to reduce the wetting time of wettable powders and to improve the penetration of water into water-dispersible granules. Examples of wetting agents used in wettable powder, suspension concentrate, and water-dispersible granule formulations are: sodium lauryl sulfate; sodium dioctyl sulfosuccinate; alkyl phenol ethoxylates; and aliphatic alcohol ethoxylates.

A dispersing agent is a substance which adsorbs onto the surface of particles and helps to preserve the state of dispersion of the particles and prevents them from reaggregating. Dispersing agents are added to agrochemical formulations to facilitate dispersion and suspension during manufacture, and to ensure the particles redisperse into water in a spray tank. They are widely used in wettable powders, suspension concentrates and water-dispersible granules. Surfactants that are used as dispersing agents have the ability to adsorb strongly onto a particle surface and provide a charged or steric barrier to reaggregation of particles. The most commonly used surfactants are anionic, non-ionic, or mixtures of the two types. For wettable powder formulations, the most common dispersing agents are sodium lignosulfonates. For suspension concentrates, very good adsorption and stabilization are obtained using polyelectrolytes, such as sodium naphthalene sulfonate formaldehyde condensates. Tristyrylphenol ethoxylate phosphate esters are also used. Non-ionics such as alkylarylethylene oxide condensates and EO-PO block copolymers are sometimes combined with anionics as dispersing agents for suspension concentrates. In recent years, new types of very high molecular weight polymeric surfactants have been developed as dispersing agents. These have very long hydrophobic ‘backbones’ and a large number of ethylene oxide chains forming the ‘teeth’ of a ‘comb’ surfactant. These high molecular weight polymers can give very good long-term stability to suspension concentrates because the hydrophobic backbones have many anchoring points onto the particle surfaces. Examples of dispersing agents used in agrochemical formulations are: sodium lignosulfonates; sodium naphthalene sulfonate formaldehyde condensates; tristyrylphenol ethoxylate phosphate esters; aliphatic alcohol ethoxylates; alkyl ethoxylates; EO-PO (ethylene oxide-propylene oxide) block copolymers; and graft copolymers.

An emulsifying agent is a substance which stabilizes a suspension of droplets of one liquid phase in another liquid phase. Without the emulsifying agent the two liquids would separate into two immiscible liquid phases. The most commonly used emulsifier blends contain alkylphenol or aliphatic alcohol with twelve or more ethylene oxide units and the oil-soluble calcium salt of dodecylbenzenesulfonic acid. A range of hydrophile-lipophile balance (“HLB”) values from 8 to 18 will normally provide good stable emulsions. Emulsion stability can sometimes be improved by the addition of a small amount of an EO-PO block copolymer surfactant.

A solubilizing agent is a surfactant which will form micelles in water at concentrations above the critical micelle concentration. The micelles are then able to dissolve or solubilize water-insoluble materials inside the hydrophobic part of the micelle. The types of surfactants usually used for solubilization are non-ionics, sorbitan monooleates, sorbitan monooleate ethoxylates, and methyl oleate esters.

Surfactants are sometimes used, either alone or with other additives such as mineral or vegetable oils as adjuvants to spray-tank mixes to improve the biological performance of the pesticide on the target. The types of surfactants used for bioenhancement depend generally on the nature and mode of action of the pesticide. However, they are often non-ionics such as: alkyl ethoxylates; linear aliphatic alcohol ethoxylates; aliphatic amine ethoxylates.

A carrier or diluent in an agricultural formulation is a material added to the pesticide to give a product of the required strength. Carriers are usually materials with high absorptive capacities, while diluents are usually materials with low absorptive capacities. Carriers and diluents are used in the formulation of dusts, wettable powders, granules, and water-dispersible granules.

Organic solvents are used mainly in the formulation of emulsifiable concentrates, oil-in-water emulsions, suspoemulsions, and ultra low volume formulations, and to a lesser extent, granular formulations. Sometimes mixtures of solvents are used. The first main groups of solvents are aliphatic paraffinic oils such as kerosene or refined paraffins. The second main group (and the most common) comprises the aromatic solvents such as xylene and higher molecular weight fractions of C9 and C10 aromatic solvents. Chlorinated hydrocarbons are useful as cosolvents to prevent crystallization of pesticides when the formulation is emulsified into water. Alcohols are sometimes used as cosolvents to increase solvent power. Other solvents may include vegetable oils, seed oils, and esters of vegetable and seed oils.

Thickeners or gelling agents are used mainly in the formulation of suspension concentrates, emulsions, and suspoemulsions to modify the rheology or flow properties of the liquid and to prevent separation and settling of the dispersed particles or droplets. Thickening, gelling, and anti-settling agents generally fall into two categories, namely water-insoluble particulates and water-soluble polymers. It is possible to produce suspension concentrate formulations using clays and silicas. Examples of these types of materials, include, but are not limited to, montmorillonite, bentonite, magnesium aluminum silicate, and attapulgite. Water-soluble polysaccharides have been used as thickening-gelling agents for many years. The types of polysaccharides most commonly used are natural extracts of seeds and seaweeds or are synthetic derivatives of cellulose. Examples of these types of materials include, but are not limited to, guar gum; locust bean gum; carrageenam; alginates; methyl cellulose; sodium carboxymethyl cellulose (SCMC); hydroxyethyl cellulose (HEC). Other types of anti-settling agents are based on modified starches, polyacrylates, polyvinyl alcohol, and polyethylene oxide. Another good anti-settling agent is xanthan gum.

Microorganisms can cause spoilage of formulated products. Therefore preservation agents are used to eliminate or reduce their effect. Examples of such agents include, but are not limited to: propionic acid and its sodium salt; sorbic acid and its sodium or potassium salts; benzoic acid and its sodium salt; p-hydroxybenzoic acid sodium salt; methyl p-hydroxybenzoate; and 1,2-benzisothiazolin-3-one (BIT).

The presence of surfactants often causes water-based formulations to foam during mixing operations in production and in application through a spray tank. In order to reduce the tendency to foam, anti-foam agents are often added either during the production stage or before filling into bottles. Generally, there are two types of anti-foam agents, namely silicones and non-silicones. Silicones are usually aqueous emulsions of dimethyl polysiloxane, while the non-silicone anti-foam agents are water-insoluble oils, such as octanol and nonanol, or silica. In both cases, the function of the anti-foam agent is to displace the surfactant from the air-water interface.

“Green” agents (e.g., adjuvants, surfactants, solvents) can reduce the overall environmental footprint of crop protection formulations. Green agents are biodegradable and generally derived from natural and/or sustainable sources, e.g., plant and animal sources. Specific examples are: vegetable oils, seed oils, and esters thereof, also alkoxylated alkyl polyglucosides.

In some instances, PMPs can be freeze-dried or lyophilized. See U.S. Pat. No. 4,311,712. The PMPs can later be reconstituted on contact with water or another liquid. Other components can be added to the lyophilized or reconstituted liposomes, for example, other pesticidal agents, agriculturally acceptable carriers, or other materials in accordance with the formulations described herein.

Other optional features of the composition include carriers or delivery vehicles that protect the pest control (e.g., biopesticide or biorepellent) composition against UV and/or acidic conditions. In some instances, the delivery vehicle contains a pH buffer. In some instances, the composition is formulated to have a pH in the range of about 4.5 to about 9.0, including for example pH ranges of about any one of 5.0 to about 8.0, about 6.5 to about 7.5, or about 6.5 to about 7.0.

The composition may additionally be formulated with an attractant (e.g., a chemoattractant) that attracts a pest to the vicinity of the composition. Attractants include pheromones, a chemical that is secreted by an animal, especially a pest, or chemoattractants which influences the behavior or development of others of the same species. Other attractants include sugar and protein hydrolysate syrups, yeasts, and rotting meat. Attractants also can be combined with an active ingredient and sprayed onto foliage or other items in the treatment area. Various attractants are known which influence a pest's behavior as a pest's search for food, oviposition, or mating sites, or mates. Attractants useful in the methods and compositions described herein include, for example, eugenol, phenethyl propionate, ethyl dimethylisobutyl-cyclopropane carboxylate, propyl benszodioxancarboxylate, cis-7,8-epoxy-2-methyloctadecane, trans-8,trans-0-dodecadienol, cis-9-tetradecenal (with cis-11-hexadecenal), trans-11-tetradecenal, cis-11-hexadecenal, (Z)-11,12-hexadecadienal, cis-7-dodecenyl acetate, cis-8-dodecenyul acetate, cis-9-dodecenyl acetate, cis-9-tetradecenyl acetate, cis-11-tetradecenyl acetate, trans-11-tetradecenyl acetate (with cis-11), cis-9,trans-11-tetradecadienyl acetate (with cis-9,trans-12), cis-9,trans-12-tetradecadienyl acetate, cis-7,cis-11-hexadecadienyl acetate (with cis-7,trans-11), cis-3,cis-13-octadecadienyl acetate, trans-3,cis-13-octadecadienyl acetate, anethole and isoamyl salicylate.

II. Heterologous Functional Agents

The PMPs manufactured herein can further include a heterologous functional agent (e.g., a heterologous agricultural agent (e.g., pesticidal agent, fertilizing agent, herbicidal agent, plant-modifying agent) or a heterologous therapeutic agent (e.g., a pathogen control agent, such as an antifungal agent, an antibacterial agent, a virucidal agent, an anti-viral agent, an insecticidal agent, a nematicidal agent, an antiparasitic agent, or an insect repellent)). For example, the PMP may encapsulate the heterologous functional agent. Alternatively, the heterologous functional agent can be embedded on or conjugated to the surface of the PMP. In some instances, the PMPs include two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different heterologous functional agents. Heterologous functional agents may be added at any step during the manufacturing process effective to introduce the agent into the manufactured PMPs.

In certain instances, the heterologous functional agent (e.g., a heterologous agricultural agent (e.g., pesticidal agent, fertilizing agent, herbicidal agent, plant-modifying agent, a heterologous nucleic acid, a heterologous polypeptide, or a heterologous small molecule) or a heterologous therapeutic agent (e.g., a pathogen control agent such as an antifungal agent, an antibacterial agent, a virucidal agent, an anti-viral agent, a nematicidal agent, an antiparasitic agent, or an insect repellent)) can be modified. For example, the modification can be a chemical modification, e.g., conjugation to a marker, e.g., fluorescent marker or a radioactive marker. In other examples, the modification can include conjugation or operational linkage to a moiety that enhances the stability, delivery, targeting, bioavailability, or half-life of the agent, e.g., a lipid, a glycan, a polymer (e.g., PEG), a cation moiety.

Examples of heterologous functional agents that can be loaded into the PMPs manufactured herein are outlined below.

A. Heterologous Agricultural Agents

The PMPs manufactured herein can include a heterologous agricultural agent (e.g., an agent that effects a plant or an organism that associates with a plant and can be loaded into a PMP), such as a pesticidal agent, herbicidal agent, fertilizing agent, or a plant-modifying agent.

For example, in some instances, the PMPs may include a pesticidal agent. The pesticidal agent can be an antifungal agent, an antibacterial agent, an insecticidal agent, a molluscicidal agent, a nematicidal agent, a virucidal agent, or a combination thereof. The pesticidal agent can be a chemical agent, such as those well known in the art. Alternatively or additionally, the pesticidal agent can be a peptide, a polypeptide, a nucleic acid, a polynucleotide, or a small molecule. The pesticidal agent may be an agent that can decrease the fitness of a variety of plant pests or can be one that targets one or more specific target plant pests (e.g., a specific species or genus of plant pests).

In some instances, the PMPs may include one or more heterologous fertilizing agents. Examples of heterologous fertilizing agents include plant nutrients or plant growth regulators, such as those well known in the art. Alternatively, or additionally, the fertilizing agent can be a peptide, a polypeptide, a nucleic acid, or a polynucleotide that can increase the fitness of a plant symbiont. The fertilizing agent may be an agent that can increase the fitness of a variety of plants or plant symbionts or can be one that targets one or more specific target plants or plant symbionts (e.g., a specific species or genera of plants or plant symbionts).

In other instances, the PMPs may include one or more heterologous plant-modifying agents. In some instances, the plant-modifying agent can include a peptide or a nucleic acid.

i. Antibacterial Agents

The PMP compositions described herein can further include an antibacterial agent. In some instances, the PMP compositions include two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different antibacterial agents. For example, the antibacterial agent can decrease the fitness of (e.g., decrease growth or kill) a bacterial plant pest (e.g., a bacterial plant pathogen). A PMP composition including an antibiotic as described herein can be contacted with a target pest, or plant infested thereof, in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of antibiotic concentration inside or on the target pest; and (b) decrease fitness of the target pest. The antibacterials described herein may be formulated in a PMP composition for any of the methods described herein, and in certain instances, may be associated with the PMP thereof.

As used herein, the term “antibacterial agent” refers to a material that kills or inhibits the growth, proliferation, division, reproduction, or spread of bacteria, such as phytopathogenic bacteria, and includes bactericidal (e.g., disinfectant compounds, antiseptic compounds, or antibiotics) or bacteriostatic agents (e.g., compounds or antibiotics). Bactericidal antibiotics kill bacteria, while bacteriostatic antibiotics only slow their growth or reproduction.

Bactericides can include disinfectants, antiseptics, or antibiotics. The most used disinfectants can comprise: active chlorine (i.e., hypochlorites (e.g., sodium hypochlorite), chloramines, dichloroisocyanurate and trichloroisocyanurate, wet chlorine, chlorine dioxide etc.), active oxygen (peroxides, such as peracetic acid, potassium persulfate, sodium perborate, sodium percarbonate and urea perhydrate), iodine (iodpovidone (povidone-iodine, Betadine), Lugol's solution, iodine tincture, iodinated nonionic surfactants), concentrated alcohols (mainly ethanol, 1-propanol, called also n-propanol and 2-propanol, called isopropanol and mixtures thereof; further, 2-phenoxyethanol and 1- and 2-phenoxypropanols are used), phenolic substances (such as phenol (also called carbolic acid), cresols (called Lysole in combination with liquid potassium soaps), halogenated (chlorinated, brominated) phenols, such as hexachlorophene, triclosan, trichlorophenol, tribromophenol, pentachlorophenol, Dibromol and salts thereof), cationic surfactants, such as some quaternary ammonium cations (such as benzalkonium chloride, cetyl trimethylammonium bromide or chloride, didecyldimethylammonium chloride, cetylpyridinium chloride, benzethonium chloride) and others, non-quaternary compounds, such as chlorhexidine, glucoprotamine, octenidine dihydrochloride etc.), strong oxidizers, such as ozone and permanganate solutions; heavy metals and their salts, such as colloidal silver, silver nitrate, mercury chloride, phenylmercury salts, copper sulfate, copper oxide-chloride, copper hydroxide, copper octanoate, copper oxychloride sulfate, copper sulfate, copper sulfate pentahydrate, etc. Heavy metals and their salts are the most toxic, and environment-hazardous bactericides and therefore, their use is strongly oppressed or canceled; further, also properly concentrated strong acids (phosphoric, nitric, sulfuric, amidosulfuric, toluenesulfonic acids) and alkalis (sodium, potassium, calcium hydroxides).

As antiseptics (i.e., germicide agents that can be used on human or animal body, skin, mucoses, wounds and the like), few of the above mentioned disinfectants can be used, under proper conditions (mainly concentration, pH, temperature and toxicity toward man/animal). Among them, important are: properly diluted chlorine preparations (i.e., Daquin's solution, 0.5% sodium or potassium hypochlorite solution, pH-adjusted to pH 7-8, or 0.5-1% solution of sodium benzenesulfochloramide (chloramine B)), some iodine preparations, such as iodopovidone in various galenics (ointment, solutions, wound plasters), in the past also Lugol's solution, peroxides as urea perhydrate solutions and pH-buffered 0.1-0.25% peracetic acid solutions, alcohols with or without antiseptic additives, used mainly for skin antisepsis, weak organic acids such as sorbic acid, benzoic acid, lactic acid and salicylic acid some phenolic compounds, such as hexachlorophene, triclosan and Dibromol, and cation-active compounds, such as 0.05-0.5% benzalkonium, 0.5-4% chlorhexidine, 0.1-2% octenidine solutions.

The PMP composition described herein may include an antibiotic. Any antibiotic known in the art may be used. Antibiotics are commonly classified based on their mechanism of action, chemical structure, or spectrum of activity.

The antibiotic described herein may target any bacterial function or growth processes and may be either bacteriostatic (e.g., slow or prevent bacterial growth) or bactericidal (e.g., kill bacteria). In some instances, the antibiotic is a bactericidal antibiotic. In some instances, the bactericidal antibiotic is one that targets the bacterial cell wall (e.g., penicillins and cephalosporins); one that targets the cell membrane (e.g., polymyxins); or one that inhibits essential bacterial enzymes (e.g., rifamycins, lipiarmycins, quinolones, and sulfonamides). In some instances, the bactericidal antibiotic is an aminoglycoside (e.g., kasugamycin). In some instances, the antibiotic is a bacteriostatic antibiotic. In some instances the bacteriostatic antibiotic targets protein synthesis (e.g., macrolides, lincosamides, and tetracyclines). Additional classes of antibiotics that may be used herein include cyclic lipopeptides (such as daptomycin), glycylcyclines (such as tigecycline), oxazolidinones (such as linezolid), or lipiarmycins (such as fidaxomicin). Examples of antibiotics include rifampicin, ciprofloxacin, doxycycline, ampicillin, and polymyxin B. The antibiotic described herein may have any level of target specificity (e.g., narrow- or broad-spectrum). In some instances, the antibiotic is a narrow-spectrum antibiotic, and thus targets specific types of bacteria, such as gram-negative or gram-positive bacteria. Alternatively, the antibiotic may be a broad-spectrum antibiotic that targets a wide range of bacteria.

Other non-limiting examples of antibiotics are found in Table 1. One skilled in the art will appreciate that a suitable concentration of each antibiotic in the composition depends on factors such as efficacy, stability of the antibiotic, number of distinct antibiotics, the formulation, and methods of application of the composition.

A PMP composition including an herbicide as described herein can be contacted with a target weed in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of herbicide concentration on the plant and (b) decrease the fitness of the weed. The herbicides described herein may be formulated in a PMP composition for any of the methods described herein, and in certain instances, may be associated with the PMP thereof.

viii. Repellents

The PMP compositions described herein can further include a repellent. In some instances, the PMP compositions include two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different repellents. For example, the repellent can repel any of the pests described herein (e.g., insects, nematodes, or mollusks); microorganisms (e.g., phytopathogens or endophytes, such as bacteria, fungi, or viruses); or weeds. A PMP composition including a repellent as described herein can be contacted with a target plant, or plant infested therewith, in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of repellent concentration; and (b) decrease the levels of the pest on the plant relative to an untreated plant. The repellent described herein may be formulated in a PMP composition for any of the methods described herein, and in certain instances, may be associated with the PMP thereof.

In some instances, the repellent is an insect repellent. Some examples of well-known insect repellents include: benzil; benzyl benzoate; 2,3,4,5-bis(butyl-2-ene)tetrahydrofurfural (MGK Repellent 11); butoxypolypropylene glycol; N-butylacetanilide; normal-butyl-6,6-dimethyl-5,6-dihydro-1,4-pyrone-2-carboxylate (Indalone); dibutyl adipate; dibutyl phthalate; di-normal-butyl succinate (Tabatrex); N,N-diethyl-meta-toluamide (DEET); dimethyl carbate (endo,endo)-dimethyl bicyclo[2.2.1] hept-5-ene-2,3-dicarboxylate); dimethyl phthalate; 2-ethyl-2-butyl-1,3-propanediol; 2-ethyl-1,3-hexanediol (Rutgers 612); di-normal-propyl isocinchomeronate (MGK Repellent 326); 2-phenylcyclohexanol; p-methane-3,8-diol, and normal-propyl N,N-diethylsuccinamate. Other repellents include citronella oil, dimethyl phthalate, normal-butylmesityl oxide oxalate and 2-ethyl hexanediol-1,3 (See, Kirk-Othmer Encyclopedia of Chemical Technology, 2nd Ed., Vol. 11: 724-728; and The Condensed Chemical Dictionary, 8th Ed., p 756).

An insect repellent may be a synthetic or nonsynthetic insect repellent. Examples of synthetic insect repellents include methyl anthranilate and other anthranilate-based insect repellents, benzaldehyde, DEET (N,N-diethyl-m-toluamide), dimethyl carbate, dimethyl phthalate, icaridin (i.e., picaridin, Bayrepel, and KBR 3023), indalone (e.g., as used in a “6-2-2” mixture (60% Dimethyl phthalate, 20% Indalone, 20% Ethylhexanediol), IR3535 (3-[N-Butyl-N-acetyl]-aminopropionic acid, ethyl ester), metofluthrin, permethrin, SS220, or tricyclodecenyl allyl ether. Examples of natural insect repellents include beautyberry (Callicarpa) leaves, birch tree bark, bog myrtle (Myrica Gale), catnip oil (e.g., nepetalactone), citronella oil, essential oil of the lemon eucalyptus (Corymbia citriodora; e.g., p-menthane-3,8-diol (PMD)), neem oil, lemongrass, tea tree oil from the leaves of Melaleuca alternifolia, tobacco, or extracts thereof.

ix. Fertilizing Agents

The PMP compositions described herein can further include a heterologous fertilizing agent. In some instances, the heterologous fertilizing agent is associated with the PMPs. For example, a PMP may encapsulate the heterologous fertilizing agent. Additionally, or alternatively, the heterologous fertilizing agent can be embedded on or conjugated to the surface of the PMP.

Examples of heterologous fertilizing agents include plant nutrients or plant growth regulators, such as those well known in the art. Alternatively, or additionally, the fertilizing agent can be a peptide, a polypeptide, a nucleic acid, or a polynucleotide that can increase the fitness of a plant symbiont. The fertilizing agent may be an agent that can increase the fitness of a variety of plants or plant symbionts or can be one that targets one or more specific target plants or plant symbionts (e.g., a specific species or genera of plants or plant symbionts).

In some instances, the heterologous fertilizing agent can be modified. For example, the modification can be a chemical modification, e.g., conjugation to a marker, e.g., fluorescent marker or a radioactive marker. In other examples, the modification can include conjugation or operational linkage to a moiety that enhances the stability, delivery, targeting, bioavailability, or half-life of the agent, e.g., a lipid, a glycan, a polymer (e.g., PEG), a cation moiety.

Examples of heterologous fertilizing agents that can be used in the presently disclosed PMP compositions and methods are outlined below.

In some instances, the heterologous fertilizing agent includes any material of natural or synthetic origin that is applied to soils or to plant tissues to supply one or more plant nutrients essential to the growth of plants. The plant nutrient may include a macronutrient, micronutrient, or a combination thereof. Plant macronutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and/or sulfur. Plant micronutrients include copper, iron, manganese, molybdenum, zinc, boron, silicon, cobalt, and/or vanadium. Examples of plant nutrient fertilizers include a nitrogen fertilizer including, but not limited to urea, ammonium nitrate, ammonium sulfate, non-pressure nitrogen solutions, aqua ammonia, anhydrous ammonia, ammonium thiosulfate, sulfur-coated urea, urea-formaldehydes, IBDU, polymer-coated urea, calcium nitrate, ureaform, or methylene urea, phosphorous fertilizers such as diammonium phosphate, monoammonium phosphate, ammonium polyphosphate, concentrated superphosphate and triple superphosphate, or potassium fertilizers such as potassium chloride, potassium sulfate, potassium-magnesium sulfate, potassium nitrate. Such compositions can exist as free salts or ions within the composition. Fertilizers may be designated by the content of one or more of its components, such as nitrogen, phosphorous, or potassium. The content of these elements in a fertilizer may be indicated by the N—P—K value (where N=nitrogen content by weight percentage, P=phosphorous content by weight percentage, and K=potassium content by weight percentage).

Inorganic fertilizers, on the other hand, are manufactured from non-living materials and include, for example, ammonium nitrate, ammonium sulfate, urea, potassium chloride, potash, ammonium phosphate, anhydrous ammonia, and other phosphate salts. Inorganic fertilizers are readily commercially available and contain nutrients in soluble form that are immediately available to the plant. Inorganic fertilizers are generally inexpensive, having a low unit cost for the desired element. One skilled in the art will appreciate that the exact amount of a given element in a fertilizing agent may be calculated and administered to the plant or soil.

Fertilizers may be further classified as either organic fertilizers or inorganic fertilizers. Organic fertilizers include fertilizers having a molecular skeleton with a carbon backbone, such as in compositions derived from living matter. Organic fertilizers are made from materials derived from living things. Animal manures, compost, bonemeal, feather meal, and blood meal are examples of common organic fertilizers. Organic fertilizers, on the other hand, are typically not immediately available to plants and require soil microorganisms to break the fertilizer components down into simpler structures prior to use by the plants. In addition, organic fertilizers may not only elicit a plant growth response as observed with common inorganic fertilizers, but natural organic fertilizers may also stimulate soil microbial population growth and activities. Increased soil microbial population (e.g., plant symbionts) may have significant beneficial effects on the physical and chemical properties of the soil, as well as increasing disease and pest resistance.

In one aspect, a PMP composition including a plant nutrient as described herein can be contacted with the plant in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of plant nutrient concentration inside or on the plant, and (b) increase the fitness of the plant relative to an untreated plant.

In another aspect, a PMP composition including a plant nutrient as described herein can be contacted with the plant symbiont in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of plant nutrient concentration inside or on the plant symbiont (e.g., a bacterial or fungal endosymbiont), and (b) increase the fitness of the plant symbiont relative to an untreated plant symbiont.

The heterologous fertilizing agent may include a plant growth regulator. Exemplary plant growth regulators include auxins, cytokinins, gibberellins, and abscisic acid. In some instances, the plant growth regulator is abscisic cacid, amidochlor, ancymidol, 6-benzylaminopurine, brassinolide, butralin, chlormequat (chlormequat chloride), choline chloride, cyclanilide, daminozide, dikegulac, dimethipin, 2,6-dimethylpuridine, ethephon, flumetralin, flurprimidol, fluthiacet, forchlorfenuron, gibberellic acid, inabenfide, indole-3-acetic acid, maleic hydrazide, mefluidide, mepiquat (mepiquat chloride), naphthaleneacetic acid, N-6-benzyladenine, paclobutrazol, prohexadione (prohexadione-calcium), prohydrojasmon, thidiazuron, triapenthenol, tributyl phosphorotrithioate, 2,3,5-tri-iodobenzoic acid, trinexapac-ethyl and uniconazole. Other plant growth regulators that can be incorporated seed coating compositions are described in US 2012/0108431, which is incorporated by reference in its entirety.

x. Plant-Modifying Agents

The PMP compositions described herein include one or more heterologous plant-modifying agents. For example, the PMPs may encapsulate the heterologous plant-modifying agent. Alternatively or additionally, the heterologous plant-modifying agent can be embedded on or conjugated to the surface of the PMP.

In some instances, the plant-modifying agent can include a peptide or a nucleic acid. The plant-modifying agent may be an agent that increases the fitness of a variety of plants or can be one that targets one or more specific plants (e.g., a specific species or genera of plants). Additionally, in some instances, the PMP compositions include two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different plant-modifying agents.

Further, in some instances, the heterologous plant-modifying agent (e.g., an agent including a nucleic acid molecule or peptide) can be modified. For example, the modification can be a chemical modification, e.g., conjugation to a marker, e.g., fluorescent marker or a radioactive marker. In other examples, the modification can include conjugation or operational linkage to a moiety that enhances the stability, delivery, targeting, bioavailability, or half-life of the agent, e.g., a lipid, a glycan, a polymer (e.g., PEG), a cation moiety.

Examples of heterologous plant-modifying agents (e.g., peptides or nucleic acids) that can be used in the presently disclosed PMP compositions and methods are outlined below.

B. Polypeptides

The PMP composition (e.g., PMPs) described herein may include a heterologous polypeptide. In some instances, the PMP composition described herein includes a polypeptide or functional fragments or derivative thereof that modifies an animal (e.g., a mammal) or a plant (e.g., increases the fitness of the animal or plant). For example, the polypeptide can increase the fitness of an animal or a plant. A PMP composition including a polypeptide as described herein can be contacted with an animal or a plant in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of polypeptide concentration; and (b) modify the animal or plant (e.g., increase the fitness of the animal or plant).

Examples of polypeptides that can be used herein can include an enzyme (e.g., a metabolic recombinase, a helicase, an integrase, a RNAse, a DNAse, or an ubiquitination protein), a pore-forming protein, a signaling ligand, a cell penetrating peptide, a transcription factor, a receptor, an antibody, a nanobody, a peptide or protein therapeutic, a gene editing protein (e.g., CRISPR-Cas system, TALEN, or zinc finger), riboprotein, a protein aptamer, or a chaperone.

Polypeptides included herein may include naturally occurring polypeptides or recombinantly produced variants. In some instances, the polypeptide may be a functional fragments or variants thereof (e.g., an enzymatically active fragment or variant thereof). For example, the polypeptide may be a functionally active variant of any of the polypeptides described herein with at least 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% identity, e.g., over a specified region or over the entire sequence, to a sequence of a polypeptide described herein or a naturally occurring polypeptide. In some instances, the polypeptide may have at least 50% (e.g., at least 50%, 60%, 70%, 80%, 90%, 95%, 97%, 99%, or greater) identity to a protein of interest.

The polypeptides described herein may be formulated in a composition for any of the uses described herein. The compositions disclosed herein may include any number or type (e.g., classes) of polypeptides, such as at least about any one of 1 polypeptide, 2, 3, 4, 5, 10, 15, 20, or more polypeptides. A suitable concentration of each polypeptide in the composition depends on factors such as efficacy, stability of the polypeptide, number of distinct polypeptides in the composition, the formulation, and methods of application of the composition. In some instances, each polypeptide in a liquid composition is from about 0.1 ng/mL to about 100 mg/mL. In some instances, each polypeptide in a solid composition is from about 0.1 ng/g to about 100 mg/g.

Methods of making a polypeptide are routine in the art. See, in general, Smales & James (Eds.), Therapeutic Proteins: Methods and Protocols (Methods in Molecular Biology), Humana Press (2005); and Crommelin, Sindelar & Meibohm (Eds.), Pharmaceutical Biotechnology: Fundamentals and Applications, Springer (2013).

Methods for producing a polypeptide involve expression in plant cells, although recombinant proteins can also be produced using insect cells, yeast, bacteria, mammalian cells, or other cells under the control of appropriate promoters. Mammalian expression vectors may comprise nontranscribed elements such as an origin of replication, a suitable promoter and enhancer, and other 5′ or 3′ flanking nontranscribed sequences, and 5′ or 3′ nontranslated sequences such as necessary ribosome binding sites, a polyadenylation site, splice donor and acceptor sites, and termination sequences. DNA sequences derived from the SV40 viral genome, for example, SV40 origin, early promoter, enhancer, splice, and polyadenylation sites may be used to provide the other genetic elements required for expression of a heterologous DNA sequence. Appropriate cloning and expression vectors for use with bacterial, fungal, yeast, and mammalian cellular hosts are described in Green & Sambrook, Molecular Cloning: A Laboratory Manual (Fourth Edition), Cold Spring Harbor Laboratory Press (2012).

Various mammalian cell culture systems can be employed to express and manufacture a recombinant polypeptide agent. Examples of mammalian expression systems include CHO cells, COS cells, HeLA and BHK cell lines. Processes of host cell culture for production of protein therapeutics are described in, e.g., Zhou and Kantardjieff (Eds.), Mammalian Cell Cultures for Biologics Manufacturing (Advances in Biochemical Engineering/Biotechnology), Springer (2014). Purification of proteins is described in Franks, Protein Biotechnology: Isolation, Characterization, and Stabilization, Humana Press (2013); and in Cutler, Protein Purification Protocols (Methods in Molecular Biology), Humana Press (2010). Formulation of protein therapeutics is described in Meyer (Ed.), Therapeutic Protein Drug Products: Practical Approaches to formulation in the Laboratory, Manufacturing, and the Clinic, Woodhead Publishing Series (2012).

In some instances, the PMP composition includes an antibody or antigen binding fragment thereof. For example, an agent described herein may be an antibody that blocks or potentiates activity and/or function of a component of the plant. The antibody may act as an antagonist or agonist of a polypeptide (e.g., enzyme or cell receptor) in the plant. The making and use of antibodies against a target antigen is known in the art. See, for example, Zhiqiang An (Ed.), Therapeutic Monoclonal Antibodies: From Bench to Clinic, 1st Edition, Wiley, 2009 and also Greenfield (Ed.), Antibodies: A Laboratory Manual, 2nd Edition, Cold Spring Harbor Laboratory Press, 2013, for methods of making recombinant antibodies, including antibody engineering, use of degenerate oligonucleotides, 5′-RACE, phage display, and mutagenesis; antibody testing and characterization; antibody pharmacokinetics and pharmacodynamics; antibody purification and storage; and screening and labeling techniques.

C. Nucleic Acids

Numerous nucleic acids are useful in the PMP compositions and methods described herein. The PMP compositions disclosed herein may include any number or type (e.g., classes) of heterologous nucleic acids (e.g., DNA molecule or RNA molecule, e.g., mRNA, guide RNA (gRNA), or inhibitory RNA molecule (e.g., siRNA, shRNA, or miRNA), or a hybrid DNA-RNA molecule), such as at least about 1 class or variant of a nucleic acid, 2, 3, 4, 5, 10, 15, 20, or more classes or variants of nucleic acids. A suitable concentration of each nucleic acid in the composition depends on factors such as efficacy, stability of the nucleic acid, number of distinct nucleic acids, the formulation, and methods of application of the composition.

A PMP composition including a nucleic acid as described herein can be contacted with a plant in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of nucleic acid concentration; and (b) modify the plant (e.g., increase the fitness of the plant).

i. Nucleic Acid Encoding Peptides

In some instances, the PMP composition includes a heterologous nucleic acid encoding a polypeptide. Nucleic acids encoding a polypeptide may have a length from about 10 to about 50,000 nucleotides (nts), about 25 to about 100 nts, about 50 to about 150 nts, about 100 to about 200 nts, about 150 to about 250 nts, about 200 to about 300 nts, about 250 to about 350 nts, about 300 to about 500 nts, about 10 to about 1000 nts, about 50 to about 1000 nts, about 100 to about 1000 nts, about 1000 to about 2000 nts, about 2000 to about 3000 nts, about 3000 to about 4000 nts, about 4000 to about 5000 nts, about 5000 to about 6000 nts, about 6000 to about 7000 nts, about 7000 to about 8000 nts, about 8000 to about 9000 nts, about 9000 to about 10,000 nts, about 10,000 to about 15,000 nts, about 10,000 to about 20,000 nts, about 10,000 to about 25,000 nts, about 10,000 to about 30,000 nts, about 10,000 to about 40,000 nts, about 10,000 to about 45,000 nts, about 10,000 to about 50,000 nts, or any range therebetween.

The PMP composition may also include functionally active variants of a nucleic acid sequence of interest. In some instances, the variant of the nucleic acids has at least 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% identity, e.g., over a specified region or over the entire sequence, to a sequence of a nucleic acid of interest. In some instances, the invention includes a functionally active polypeptide encoded by a nucleic acid variant as described herein. In some instances, the functionally active polypeptide encoded by the nucleic acid variant has at least 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% identity, e.g., over a specified region or over the entire amino acid sequence, to a sequence of a polypeptide of interest or the naturally derived polypeptide sequence.

Certain methods for expressing a nucleic acid encoding a protein may involve expression in cells, including insect, yeast, plant, bacteria, or other cells under the control of appropriate promoters. Expression vectors may include nontranscribed elements, such as an origin of replication, a suitable promoter and enhancer, and other 5′ or 3′ flanking nontranscribed sequences, and 5′ or 3′ nontranslated sequences such as necessary ribosome binding sites, a polyadenylation site, splice donor and acceptor sites, and termination sequences. DNA sequences derived from the SV40 viral genome, for example, SV40 origin, early promoter, enhancer, splice, and polyadenylation sites may be used to provide the other genetic elements required for expression of a heterologous DNA sequence. Appropriate cloning and expression vectors for use with bacterial, fungal, yeast, and mammalian cellular hosts are described in Green et al., Molecular Cloning: A Laboratory Manual, Fourth Edition, Cold Spring Harbor Laboratory Press, 2012.

Genetic modification using recombinant methods is generally known in the art. A nucleic acid sequence coding for a desired gene can be obtained using recombinant methods known in the art, such as, for example by screening libraries from cells expressing the gene, by deriving the gene from a vector known to include the same, or by isolating directly from cells and tissues containing the same, using standard techniques. Alternatively, a gene of interest can be produced synthetically, rather than cloned.

Expression of natural or synthetic nucleic acids is typically achieved by operably linking a nucleic acid encoding the gene of interest to a promoter, and incorporating the construct into an expression vector. Expression vectors can be suitable for replication and expression in bacteria. Expression vectors can also be suitable for replication and integration in eukaryotes. Typical cloning vectors contain transcription and translation terminators, initiation sequences, and promoters useful for expression of the desired nucleic acid sequence.

Additional promoter elements, e.g., enhancers, regulate the frequency of transcriptional initiation. Typically, these are located in the region 30-110 basepairs (bp) upstream of the start site, although a number of promoters have recently been shown to contain functional elements downstream of the start site as well. The spacing between promoter elements frequently is flexible, so that promoter function is preserved when elements are inverted or moved relative to one another. In the thymidine kinase (tk) promoter, the spacing between promoter elements can be increased to 50 bp apart before activity begins to decline. Depending on the promoter, it appears that individual elements can function either cooperatively or independently to activate transcription.

One example of a suitable promoter is the immediate early cytomegalovirus (CMV) promoter sequence. This promoter sequence is a strong constitutive promoter sequence capable of driving high levels of expression of any polynucleotide sequence operatively linked thereto. Another example of a suitable promoter is Elongation Growth Factor-1α (EF-1α). However, other constitutive promoter sequences may also be used, including, but not limited to the simian virus 40 (SV40) early promoter, mouse mammary tumor virus (MMTV), human immunodeficiency virus (HIV) long terminal repeat (LTR) promoter, MoMuLV promoter, an avian leukemia virus promoter, an Epstein-Barr virus immediate early promoter, a Rous sarcoma virus promoter, as well as human gene promoters such as, but not limited to, the actin promoter, the myosin promoter, the hemoglobin promoter, and the creatine kinase promoter.

Alternatively, the promoter may be an inducible promoter. The use of an inducible promoter provides a molecular switch capable of turning on expression of the polynucleotide sequence which it is operatively linked when such expression is desired, or turning off the expression when expression is not desired. Examples of inducible promoters include, but are not limited to a metallothionine promoter, a glucocorticoid promoter, a progesterone promoter, and a tetracycline promoter.

The expression vector to be introduced can also contain either a selectable marker gene or a reporter gene or both to facilitate identification and selection of expressing cells from the population of cells sought to be transfected or infected through viral vectors. In other aspects, the selectable marker may be carried on a separate piece of DNA and used in a co-transfection procedure. Both selectable markers and reporter genes may be flanked with appropriate regulatory sequences to enable expression in the host cells. Useful selectable markers include, for example, antibiotic-resistance genes, such as neo and the like.

Reporter genes may be used for identifying potentially transformed cells and for evaluating the functionality of regulatory sequences. In general, a reporter gene is a gene that is not present in or expressed by the recipient source and that encodes a polypeptide whose expression is manifested by some easily detectable property, e.g., enzymatic activity. Expression of the reporter gene is assayed at a suitable time after the DNA has been introduced into the recipient cells. Suitable reporter genes may include genes encoding luciferase, beta-galactosidase, chloramphenicol acetyl transferase, secreted alkaline phosphatase, or the green fluorescent protein gene (e.g., Ui-Tei et al., FEBS Letters 479:79-82, 2000). Suitable expression systems are well known and may be prepared using known techniques or obtained commercially. In general, the construct with the minimal 5′ flanking region showing the highest level of expression of reporter gene is identified as the promoter. Such promoter regions may be linked to a reporter gene and used to evaluate agents for the ability to modulate promoter-driven transcription.

In some instances, an organism may be genetically modified to alter expression of one or more proteins. Expression of the one or more proteins may be modified for a specific time, e.g., development or differentiation state of the organism. In one instances, the invention includes a composition to alter expression of one or more proteins, e.g., proteins that affect activity, structure, or function. Expression of the one or more proteins may be restricted to a specific location(s) or widespread throughout the organism.

ii. Synthetic mRNA

The PMP composition may include a synthetic mRNA molecule, e.g., a synthetic mRNA molecule encoding a polypeptide. The synthetic mRNA molecule can be modified, e.g., chemically. The mRNA molecule can be chemically synthesized or transcribed in vitro. The mRNA molecule can be disposed on a plasmid, e.g., a viral vector, bacterial vector, or eukaryotic expression vector. In some examples, the mRNA molecule can be delivered to cells by transfection, electroporation, or transduction (e.g., adenoviral or lentiviral transduction).

In some instances, the modified RNA agent of interest described herein has modified nucleosides or nucleotides. Such modifications are known and are described, e.g., in WO 2012/019168. Additional modifications are described, e.g., in WO 2015/038892; WO 2015/038892; WO 2015/089511; WO 2015/196130; WO 2015/196118 and WO 2015/196128 A2.

In some instances, the modified RNA encoding a polypeptide of interest has one or more terminal modification, e.g., a 5′ cap structure and/or a poly-A tail (e.g., of between 100-200 nucleotides in length). The 5′ cap structure may be selected from the group consisting of CapO, Capl, ARCA, inosine, NI-methyl-guanosine, 2′fluoro-guanosine, 7-deaza-guanosine, 8-oxo-guanosine, 2-amino-guanosine, LNA-guanosine, and 2-azido-guanosine. In some cases, the modified RNAs also contain a 5′ UTR including at least one Kozak sequence, and a 3′ UTR. Such modifications are known and are described, e.g., in WO 2012/135805 and WO 2013/052523. Additional terminal modifications are described, e.g., in WO 2014/164253 and WO 2016/011306, WO 2012/045075, and WO 2014/093924. Chimeric enzymes for synthesizing capped RNA molecules (e.g., modified mRNA) which may include at least one chemical modification are described in WO 2014/028429.

In some instances, a modified mRNA may be cyclized, or concatemerized, to generate a translation competent molecule to assist interactions between poly-A binding proteins and 5′-end binding proteins. The mechanism of cyclization or concatemerization may occur through at least 3 different routes: 1) chemical, 2) enzymatic, and 3) ribozyme catalyzed. The newly formed 5′-/3′-linkage may be intramolecular or intermolecular. Such modifications are described, e.g., in WO 2013/151736.

Methods of making and purifying modified RNAs are known and disclosed in the art. For example, modified RNAs are made using only in vitro transcription (IVT) enzymatic synthesis. Methods of making IVT polynucleotides are known in the art and are described in WO 2013/151666, WO 2013/151668, WO 2013/151663, WO 2013/151669, WO 2013/151670, WO 2013/151664, WO 2013/151665, WO 2013/151671, WO 2013/151672, WO 2013/151667 and WO 2013/151736. Methods of purification include purifying an RNA transcript including a polyA tail by contacting the sample with a surface linked to a plurality of thymidines or derivatives thereof and/or a plurality of uracils or derivatives thereof (polyT/U) under conditions such that the RNA transcript binds to the surface and eluting the purified RNA transcript from the surface (WO 2014/152031); using ion (e.g., anion) exchange chromatography that allows for separation of longer RNAs up to 10,000 nucleotides in length via a scalable method (WO 2014/144767); and subjecting a modified mRNA sample to DNAse treatment (WO 2014/152030).

Formulations of modified RNAs are known and are described, e.g., in WO 2013/090648. For example, the formulation may be, but is not limited to, nanoparticles, poly(lactic-co-glycolic acid)(PLGA) microspheres, lipidoids, lipoplex, liposome, polymers, carbohydrates (including simple sugars), cationic lipids, fibrin gel, fibrin hydrogel, fibrin glue, fibrin sealant, fibrinogen, thrombin, rapidly eliminated lipid nanoparticles (reLNPs) and combinations thereof.

Modified RNAs encoding polypeptides in the fields of human disease, antibodies, viruses, and a variety of in vivo settings are known and are disclosed in for example, Table 6 of International Publication Nos. WO 2013/151666, WO 2013/151668, WO 2013/151663, WO 2013/151669, WO 2013/151670, WO 2013/151664, WO 2013/151665, WO 2013/151736; Tables 6 and 7 International Publication No. WO 2013/151672; Tables 6, 178 and 179 of International Publication No. WO 2013/151671; Tables 6, 185 and 186 of International Publication No WO 2013/151667. Any of the foregoing may be synthesized as an IVT polynucleotide, chimeric polynucleotide or a circular polynucleotide, and each may include one or more modified nucleotides or terminal modifications.

iii. Inhibitory RNA

In some instances, the PMP composition includes an inhibitory RNA molecule, e.g., that acts via the RNA interference (RNAi) pathway. In some instances, the inhibitory RNA molecule decreases the level of gene expression in a plant and/or decreases the level of a protein in the plant. In some instances, the inhibitory RNA molecule inhibits expression of a plant gene. For example, an inhibitory RNA molecule may include a short interfering RNA, short hairpin RNA, and/or a microRNA that targets a gene in the plant. Certain RNA molecules can inhibit gene expression through the biological process of RNA interference (RNAi). RNAi molecules include RNA or RNA-like structures typically containing 15-50 base pairs (such as about 18-25 base pairs) and having a nucleobase sequence identical (complementary) or nearly identical (substantially complementary) to a coding sequence in an expressed target gene within the cell. RNAi molecules include, but are not limited to: short interfering RNAs (siRNAs), double-strand RNAs (dsRNA), short hairpin RNAs (shRNA), meroduplexes, dicer substrates, and multivalent RNA interference (U.S. Pat. Nos. 8,084,599 8,349,809, 8,513,207 and 9,200,276). A shRNA is a RNA molecule including a hairpin turn that decreases expression of target genes via RNAi. shRNAs can be delivered to cells in the form of plasmids, e.g., viral or bacterial vectors, e.g., by transfection, electroporation, or transduction). A microRNA is a non-coding RNA molecule that typically has a length of about 22 nucleotides. MiRNAs bind to target sites on mRNA molecules and silence the mRNA, e.g., by causing cleavage of the mRNA, destabilization of the mRNA, or inhibition of translation of the mRNA. In some instances, the inhibitory RNA molecule decreases the level and/or activity of a negative regulator of function. In other instances, the inhibitor RNA molecule decreases the level and/or activity of an inhibitor of a positive regulator of function. The inhibitory RNA molecule can be chemically synthesized or transcribed in vitro.

In some instances, the nucleic acid is a DNA, a RNA, or a PNA. In some instances, the RNA is an inhibitory RNA. In some instances, the inhibitory RNA inhibits gene expression in a plant. In some instances, the nucleic acid is an mRNA, a modified mRNA, or a DNA molecule that, in the plant, increases expression of an enzyme (e.g., a metabolic recombinase, a helicase, an integrase, a RNAse, a DNAse, or an ubiquitination protein), a pore-forming protein, a signaling ligand, a cell penetrating peptide, a transcription factor, a receptor, an antibody, a nanobody, a gene editing protein (e.g., CRISPR-Cas system, TALEN, or zinc finger), riboprotein, a protein aptamer, or a chaperone. In some instances, the nucleic acid is an mRNA, a modified mRNA, or a DNA molecule that increases the expression of an enzyme (e.g., a metabolic enzyme, a recombinase enzyme, a helicase enzyme, an integrase enzyme, a RNAse enzyme, a DNAse enzyme, or an ubiquitination protein), a pore-forming protein, a signaling ligand, a cell penetrating peptide, a transcription factor, a receptor, an antibody, a nanobody, a gene editing protein (e.g., a CRISPR-Cas system, a TALEN, or a zinc finger), a riboprotein, a protein aptamer, or a chaperone. In some instances, the increase in expression in the plant is an increase in expression of about 5%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100% relative to a reference level (e.g., the expression in an untreated plant). In some instances, the increase in expression in the plant is an increase in expression of about 2× fold, about 4× fold, about 5× fold, about 10× fold, about 20× fold, about 25× fold, about 50× fold, about 75× fold, or about 100× fold or more, relative to a reference level (e.g., the expression in an untreated plant).

In some instances, the nucleic acid is an antisense RNA, a siRNA, a shRNA, a miRNA, an aiRNA, a PNA, a morpholino, a LNA, a piRNA, a ribozyme, a DNAzyme, an aptamer (DNA, RNA), a circRNA, a gRNA, or a DNA molecules (e.g., an antisense polynucleotide) to reduces, in the plant, expression of, e.g., an enzyme (a metabolic enzyme, a recombinase enzyme, a helicase enzyme, an integrase enzyme, a RNAse enzyme, a DNAse enzyme, a polymerase enzyme, a ubiquitination protein, a superoxide management enzyme, or an energy production enzyme), a transcription factor, a secretory protein, a structural factor (actin, kinesin, ortubulin), a riboprotein, a protein aptamer, a chaperone, a receptor, a signaling ligand, or a transporter. In some instances, the decrease in expression in the plant is a decrease in expression of about 5%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100% relative to a reference level (e.g., the expression in an untreated plant). In some instances, the decrease in expression in the plant is a decrease in expression of about 2× fold, about 4× fold, about 5× fold, about 10× fold, about 20× fold, about 25× fold, about 50× fold, about 75× fold, or about 100× fold or more, relative to a reference level (e.g., the expression in an untreated plant).

RNAi molecules include a sequence substantially complementary, or fully complementary, to all or a fragment of a target gene. RNAi molecules may complement sequences at the boundary between introns and exons to prevent the maturation of newly-generated nuclear RNA transcripts of specific genes into mRNA for transcription. RNAi molecules complementary to specific genes can hybridize with the mRNA for a target gene and prevent its translation. The antisense molecule can be DNA, RNA, or a derivative or hybrid thereof. Examples of such derivative molecules include, but are not limited to, peptide nucleic acid (PNA) and phosphorothioate-based molecules such as deoxyribonucleic guanidine (DNG) or ribonucleic guanidine (RNG).

RNAi molecules can be provided as ready-to-use RNA synthesized in vitro or as an antisense gene transfected into cells which will yield RNAi molecules upon transcription. Hybridization with mRNA results in degradation of the hybridized molecule by RNAse H and/or inhibition of the formation of translation complexes. Both result in a failure to produce the product of the original gene.

The length of the RNAi molecule that hybridizes to the transcript of interest may be around 10 nucleotides, between about 15 or 30 nucleotides, or about 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 or more nucleotides. The degree of identity of the antisense sequence to the targeted transcript may be at least 75%, at least 80%, at least 85%, at least 90%, or at least 95.

RNAi molecules may also include overhangs, i.e., typically unpaired, overhanging nucleotides which are not directly involved in the double helical structure normally formed by the core sequences of the herein defined pair of sense strand and antisense strand. RNAi molecules may contain 3′ and/or 5′ overhangs of about 1-5 bases independently on each of the sense strands and antisense strands. In some instances, both the sense strand and the antisense strand contain 3′ and 5′ overhangs. In some instances, one or more of the 3′ overhang nucleotides of one strand base pairs with one or more 5′ overhang nucleotides of the other strand. In other instances, the one or more of the 3′ overhang nucleotides of one strand base do not pair with the one or more 5′ overhang nucleotides of the other strand. The sense and antisense strands of an RNAi molecule may or may not contain the same number of nucleotide bases. The antisense and sense strands may form a duplex wherein the 5′ end only has a blunt end, the 3′ end only has a blunt end, both the 5′ and 3′ ends are blunt ended, or neither the 5′ end nor the 3′ end are blunt ended. In another instance, one or more of the nucleotides in the overhang contains a thiophosphate, phosphorothioate, deoxynucleotide inverted (3′ to 3′ linked) nucleotide or is a modified ribonucleotide or deoxynucleotide.

Small interfering RNA (siRNA) molecules include a nucleotide sequence that is identical to about 15 to about 25 contiguous nucleotides of the target mRNA. In some instances, the siRNA sequence commences with the dinucleotide AA, includes a GC-content of about 30-70% (about 30-60%, about 40-60%, or about 45%-55%), and does not have a high percentage identity to any nucleotide sequence other than the target in the genome in which it is to be introduced, for example as determined by standard BLAST search.

siRNAs and shRNAs resemble intermediates in the processing pathway of the endogenous microRNA (miRNA) genes (Bartel, Cell 116:281-297, 2004). In some instances, siRNAs can function as miRNAs and vice versa (Zeng et al., Mol. Cell 9:1327-1333, 2002; Doench et al., Genes Dev. 17:438-442, 2003). Exogenous siRNAs downregulate mRNAs with seed complementarity to the siRNA (Birmingham et al., Nat. Methods 3:199-204, 2006). Multiple target sites within a 3′ UTR give stronger downregulation (Doench et al., Genes Dev. 17:438-442, 2003).

Known effective siRNA sequences and cognate binding sites are also well represented in the relevant literature. RNAi molecules are readily designed and produced by technologies known in the art. In addition, there are computational tools that increase the chance of finding effective and specific sequence motifs (Pei et al., Nat. Methods 3(9):670-676, 2006; Reynolds et al., Nat. Biotechnol. 22(3):326-330, 2004; Khvorova et al., Nat. Struct. Biol. 10(9):708-712, 2003; Schwarz et al., Cell 115(2):199-208, 2003; Ui-Tei et al., Nucleic Acids Res. 32(3):936-948, 2004; Heale et al., Nucleic Acids Res. 33(3):e30, 2005; Chalk et al., Biochem. Biophys. Res. Commun. 319(1):264-274, 2004; and Amarzguioui et al., Biochem. Biophys. Res. Commun. 316(4):1050-1058, 2004).

The RNAi molecule modulates expression of RNA encoded by a gene. Because multiple genes can share some degree of sequence homology with each other, in some instances, the RNAi molecule can be designed to target a class of genes with sufficient sequence homology. In some instances, the RNAi molecule can contain a sequence that has complementarity to sequences that are shared amongst different gene targets or are unique for a specific gene target. In some instances, the RNAi molecule can be designed to target conserved regions of an RNA sequence having homology between several genes thereby targeting several genes in a gene family (e.g., different gene isoforms, splice variants, mutant genes, etc.). In some instances, the RNAi molecule can be designed to target a sequence that is unique to a specific RNA sequence of a single gene.

An inhibitory RNA molecule can be modified, e.g., to contain modified nucleotides, e.g., 2′-fluoro, 2′-o-methyl, 2′-deoxy, unlocked nucleic acid, 2′-hydroxy, phosphorothioate, 2′-thiouridine, 4′-thiouridine, 2′-deoxyuridine. Without being bound by theory, it is believed that such modifications can increase nuclease resistance and/or serum stability, or decrease immunogenicity.

In some instances, the RNAi molecule is linked to a delivery polymer via a physiologically labile bond or linker. The physiologically labile linker is selected such that it undergoes a chemical transformation (e.g., cleavage) when present in certain physiological conditions, (e.g., disulfide bond cleaved in the reducing environment of the cell cytoplasm). Release of the molecule from the polymer, by cleavage of the physiologically labile linkage, facilitates interaction of the molecule with the appropriate cellular components for activity.

The RNAi molecule-polymer conjugate may be formed by covalently linking the molecule to the polymer. The polymer is polymerized or modified such that it contains a reactive group A. The RNAi molecule is also polymerized or modified such that it contains a reactive group B. Reactive groups A and B are chosen such that they can be linked via a reversible covalent linkage using methods known in the art.

Conjugation of the RNAi molecule to the polymer can be performed in the presence of an excess of polymer. Because the RNAi molecule and the polymer may be of opposite charge during conjugation, the presence of excess polymer can reduce or eliminate aggregation of the conjugate. Alternatively, an excess of a carrier polymer, such as a polycation, can be used. The excess polymer can be removed from the conjugated polymer prior to administration of the conjugate. Alternatively, the excess polymer can be co-administered with the conjugate.

The making and use of inhibitory agents based on non-coding RNA such as ribozymes, RNAse P, siRNAs, and miRNAs are also known in the art, for example, as described in Sioud, RNA Therapeutics: Function, Design, and Delivery (Methods in Molecular Biology). Humana Press (2010).

iv. Gene Editing

The PMP compositions described herein may include a component of a gene editing system. For example, the agent may introduce an alteration (e.g., insertion, deletion (e.g., knockout), translocation, inversion, single point mutation, or other mutation) in a gene in the plant. Exemplary gene editing systems include the zinc finger nucleases (ZFNs), Transcription Activator-Like Effector-based Nucleases (TALEN), and the clustered regulatory interspaced short palindromic repeat (CRISPR) system. ZFNs, TALENs, and CRISPR-based methods are described, e.g., in Gaj et al., Trends Biotechnol. 31(7):397-405, 2013.

In a typical CRISPR/Cas system, an endonuclease is directed to a target nucleotide sequence (e.g., a site in the genome that is to be sequence-edited) by sequence-specific, non-coding guide RNAs that target single- or double-stranded DNA sequences. Three classes (I-III) of CRISPR systems have been identified. The class II CRISPR systems use a single Cas endonuclease (rather than multiple Cas proteins). One class II CRISPR system includes a type II Cas endonuclease such as Cas9, a CRISPR RNA (crRNA), and a trans-activating crRNA (tracrRNA). The crRNA contains a guide RNA, i.e., typically an about 20-nucleotide RNA sequence that corresponds to a target DNA sequence. The crRNA also contains a region that binds to the tracrRNA to form a partially double-stranded structure which is cleaved by RNase III, resulting in a crRNA/tracrRNA hybrid. The RNAs serve as guides to direct Cas proteins to silence specific DNA/RNA sequences, depending on the spacer sequence. See, e.g., Horvath et al., Science 327:167-170, 2010; Makarova et al., Biology Direct 1:7, 2006; Pennisi, Science 341:833-836, 2013. The target DNA sequence must generally be adjacent to a protospacer adjacent motif (PAM) that is specific for a given Cas endonuclease; however, PAM sequences appear throughout a given genome. CRISPR endonucleases identified from various prokaryotic species have unique PAM sequence requirements; examples of PAM sequences include 5′-NGG (SEQ ID NO: 78) (Streptococcus pyogenes), 5′-NNAGAA (SEQ ID NO: 79) (Streptococcus thermophilus CRISPR1), 5′-NGGNG (SEQ ID NO: 80) (Streptococcus thermophilus CRISPR3), and 5′-NNNGATT (SEQ ID NO: 81) (Neisseria meningiditis).

Some endonucleases, e.g., Cas9 endonucleases, are associated with G-rich PAM sites, e.g., 5′-NGG (SEQ ID NO: 78), and perform blunt-end cleaving of the target DNA at a location 3 nucleotides upstream from (5′ from) the PAM site. Another class II CRISPR system includes the type V endonuclease Cpf1, which is smaller than Cas9; examples include AsCpf1 (from Acidaminococcus sp.) and LbCpf1 (from Lachnospiraceae sp.). Cpf1-associated CRISPR arrays are processed into mature crRNAs without the requirement of a tracrRNA; in other words a Cpf1 system requires only the Cpf1 nuclease and a crRNA to cleave the target DNA sequence. Cpf1 endonucleases, are associated with T-rich PAM sites, e.g., 5′-TTN. Cpf1 can also recognize a 5′-CTA PAM motif. Cpf1 cleaves the target DNA by introducing an offset or staggered double-strand break with a 4- or 5-nucleotide 5′ overhang, for example, cleaving a target DNA with a 5-nucleotide offset or staggered cut located 18 nucleotides downstream from (3′ from) from the PAM site on the coding strand and 23 nucleotides downstream from the PAM site on the complimentary strand; the 5-nucleotide overhang that results from such offset cleavage allows more precise genome editing by DNA insertion by homologous recombination than by insertion at blunt-end cleaved DNA. See, e.g., Zetsche et al., Cell 163:759-771, 2015.

For the purposes of gene editing, CRISPR arrays can be designed to contain one or multiple guide RNA sequences corresponding to a desired target DNA sequence; see, for example, Cong et al., Science 339:819-823, 2013; Ran et al., Nature Protocols 8:2281-2308, 2013. At least about 16 or 17 nucleotides of gRNA sequence are required by Cas9 for DNA cleavage to occur; for Cpf1 at least about 16 nucleotides of gRNA sequence is needed to achieve detectable DNA cleavage. In practice, guide RNA sequences are generally designed to have a length of between 17-24 nucleotides (e.g., 19, 20, or 21 nucleotides) and complementarity to the targeted gene or nucleic acid sequence. Custom gRNA generators and algorithms are available commercially for use in the design of effective guide RNAs. Gene editing has also been achieved using a chimeric single guide RNA (sgRNA), an engineered (synthetic) single RNA molecule that mimics a naturally occurring crRNA-tracrRNA complex and contains both a tracrRNA (for binding the nuclease) and at least one crRNA (to guide the nuclease to the sequence targeted for editing). Chemically modified sgRNAs have also been demonstrated to be effective in genome editing; see, for example, Hendel et al., Nature Biotechnol. 985-991, 2015.

Whereas wild-type Cas9 generates double-strand breaks (DSBs) at specific DNA sequences targeted by a gRNA, a number of CRISPR endonucleases having modified functionalities are available, for example: a nickase version of Cas9 generates only a single-strand break; a catalytically inactive Cas9 (dCas9) does not cut the target DNA but interferes with transcription by steric hindrance. dCas9 can further be fused with an effector to repress (CRISPRi) or activate (CRISPRa) expression of a target gene. For example, Cas9 can be fused to a transcriptional repressor (e.g., a KRAB domain) or a transcriptional activator (e.g., a dCas9-VP64 fusion). A catalytically inactive Cas9 (dCas9) fused to Fokl nuclease (dCas9-Fokl) can be used to generate DSBs at target sequences homologous to two gRNAs. See, e.g., the numerous CRISPR/Cas9 plasmids disclosed in and publicly available from the Addgene repository (Addgene, 75 Sidney St., Suite 550A, Cambridge, Mass. 02139; addgene.org/crispr/). A double nickase Cas9 that introduces two separate double-strand breaks, each directed by a separate guide RNA, is described as achieving more accurate genome editing by Ran et al., Cell 154:1380-1389, 2013.

CRISPR technology for editing the genes of eukaryotes is disclosed in US Patent Application Publications US 2016/0138008 A1 and US 2015/0344912 A1, and in U.S. Pat. Nos. 8,697,359, 8,771,945, 8,945,839, 8,999,641, 8,993,233, 8,895,308, 8,865,406, 8,889,418, 8,871,445, 8,889,356, 8,932,814, 8,795,965, and 8,906,616. Cpf1 endonuclease and corresponding guide RNAs and PAM sites are disclosed in US Patent Application Publication 2016/0208243 A1.

In some instances, the desired genome modification involves homologous recombination, wherein one or more double-stranded DNA breaks in the target nucleotide sequence is generated by the RNA-guided nuclease and guide RNA(s), followed by repair of the break(s) using a homologous recombination mechanism (homology-directed repair). In such instances, a donor template that encodes the desired nucleotide sequence to be inserted or knocked-in at the double-stranded break is provided to the cell or subject; examples of suitable templates include single-stranded DNA templates and double-stranded DNA templates (e.g., linked to the polypeptide described herein). In general, a donor template encoding a nucleotide change over a region of less than about 50 nucleotides is provided in the form of single-stranded DNA; larger donor templates (e.g., more than 100 nucleotides) are often provided as double-stranded DNA plasmids. In some instances, the donor template is provided to the cell or subject in a quantity that is sufficient to achieve the desired homology-directed repair but that does not persist in the cell or subject after a given period of time (e.g., after one or more cell division cycles). In some instances, a donor template has a core nucleotide sequence that differs from the target nucleotide sequence (e.g., a homologous endogenous genomic region) by at least 1, at least 5, at least 10, at least 20, at least 30, at least 40, at least 50, or more nucleotides. This core sequence is flanked by homology arms or regions of high sequence identity with the targeted nucleotide sequence; in some instances, the regions of high identity include at least 10, at least 50, at least 100, at least 150, at least 200, at least 300, at least 400, at least 500, at least 600, at least 750, or at least 1000 nucleotides on each side of the core sequence. In some instances where the donor template is in the form of a single-stranded DNA, the core sequence is flanked by homology arms including at least 10, at least 20, at least 30, at least 40, at least 50, at least 60, at least 70, at least 80, or at least 100 nucleotides on each side of the core sequence. In instances, where the donor template is in the form of a double-stranded DNA, the core sequence is flanked by homology arms including at least 500, at least 600, at least 700, at least 800, at least 900, or at least 1000 nucleotides on each side of the core sequence. In one instance, two separate double-strand breaks are introduced into the cell or subject's target nucleotide sequence with a double nickase Cas9 (see Ran et al., Cell 154:1380-1389, 2013), followed by delivery of the donor template.

In some instances, the composition includes a gRNA and a targeted nuclease, e.g., a Cas9, e.g., a wild type Cas9, a nickase Cas9 (e.g., Cas9 D10A), a dead Cas9 (dCas9), eSpCas9, Cpf1, C2C1, or C2C3, or a nucleic acid encoding such a nuclease. The choice of nuclease and gRNA(s) is determined by whether the targeted mutation is a deletion, substitution, or addition of nucleotides, e.g., a deletion, substitution, or addition of nucleotides to a targeted sequence. Fusions of a catalytically inactive endonuclease e.g., a dead Cas9 (dCas9, e.g., D10A; H840A) tethered with all or a portion of (e.g., biologically active portion of) an (one or more) effector domain create chimeric proteins that can be linked to the polypeptide to guide the composition to specific DNA sites by one or more RNA sequences (sgRNA) to modulate activity and/or expression of one or more target nucleic acids sequences.

In instances, the agent includes a guide RNA (gRNA) for use in a CRISPR system for gene editing. In some instances, the agent includes a zinc finger nuclease (ZFN), or a mRNA encoding a ZFN, that targets (e.g., cleaves) a nucleic acid sequence (e.g., DNA sequence) of a gene in the plant. In some instances, the agent includes a TALEN, or an mRNA encoding a TALEN, that targets (e.g., cleaves) a nucleic acid sequence (e.g., DNA sequence) in a gene in the plant.

For example, the gRNA can be used in a CRISPR system to engineer an alteration in a gene in the plant. In other examples, the ZFN and/or TALEN can be used to engineer an alteration in a gene in the plant. Exemplary alterations include insertions, deletions (e.g., knockouts), translocations, inversions, single point mutations, or other mutations. The alteration can be introduced in the gene in a cell, e.g., in vitro, ex vivo, or in vivo. In some examples, the alteration increases the level and/or activity of a gene in the plant. In other examples, the alteration decreases the level and/or activity of (e.g., knocks down or knocks out) a gene in the plant. In yet another example, the alteration corrects a defect (e.g., a mutation causing a defect), in a gene in the plant.

In some instances, the CRISPR system is used to edit (e.g., to add or delete a base pair) a target gene in the plant. In other instances, the CRISPR system is used to introduce a premature stop codon, e.g., thereby decreasing the expression of a target gene. In yet other instances, the CRISPR system is used to turn off a target gene in a reversible manner, e.g., similarly to RNA interference. In some instances, the CRISPR system is used to direct Cas to a promoter of a gene, thereby blocking an RNA polymerase sterically.

In some instances, a CRISPR system can be generated to edit a gene in the plant, using technology described in, e.g., U.S. Publication No. 20140068797, Cong, Science 339: 819-823, 2013; Tsai, Nature Biotechnol. 32:6 569-576, 2014; U.S. Pat. Nos. 8,871,445; 8,865,406; 8,795,965; 8,771,945; and 8,697,359.

In some instances, the CRISPR interference (CRISPRi) technique can be used for transcriptional repression of specific genes in the plant. In CRISPRi, an engineered Cas9 protein (e.g., nuclease-null dCas9, or dCas9 fusion protein, e.g., dCas9-KRAB or dCas9-SID4X fusion) can pair with a sequence specific guide RNA (sgRNA). The Cas9-gRNA complex can block RNA polymerase, thereby interfering with transcription elongation. The complex can also block transcription initiation by interfering with transcription factor binding. The CRISPRi method is specific with minimal off-target effects and is multiplexable, e.g., can simultaneously repress more than one gene (e.g., using multiple gRNAs). Also, the CRISPRi method permits reversible gene repression.

In some instances, CRISPR-mediated gene activation (CRISPRa) can be used for transcriptional activation of a gene in the plant. In the CRISPRa technique, dCas9 fusion proteins recruit transcriptional activators. For example, dCas9 can be fused to polypeptides (e.g., activation domains) such as VP64 or the p65 activation domain (p65D) and used with sgRNA (e.g., a single sgRNA or multiple sgRNAs), to activate a gene or genes in the plant. Multiple activators can be recruited by using multiple sgRNAs—this can increase activation efficiency. A variety of activation domains and single or multiple activation domains can be used. In addition to engineering dCas9 to recruit activators, sgRNAs can also be engineered to recruit activators. For example, RNA aptamers can be incorporated into a sgRNA to recruit proteins (e.g., activation domains) such as VP64. In some examples, the synergistic activation mediator (SAM) system can be used for transcriptional activation. In SAM, MS2 aptamers are added to the sgRNA. MS2 recruits the MS2 coat protein (MCP) fused to p65AD and heat shock factor 1 (HSF1).

The CRISPRi and CRISPRa techniques are described in greater detail, e.g., in Dominguez et al., Nat. Rev. Mol. Cell Biol. 17:5-15, 2016, incorporated herein by reference. In addition, dCas9-mediated epigenetic modifications and simultaneous activation and repression using CRISPR systems, as described in Dominguez et al., can be used to modulate a gene in the plant.

D. Heterologous Therapeutic Agents

The PMPs manufactured herein can include a heterologous therapeutic agent (e.g., an agent that affects an animal (e.g., human), an animal pathogen, or a pathogen vector thereof, and can be loaded into a PMP), such as a pathogen control agent (e.g., antifungal agent, an antibacterial agent, a virucidal agent, an anti-viral agent, an insecticidal agent, a nematicidal agent, an antiparasitic agent, or an insect repellent). PMPs loaded with such agents can be formulated with a pharmaceutically acceptable carrier for delivery to an animal, an animal pathogen, or a pathogen vector thereof.

i. Antibacterial Agents

The PMP compositions described herein can further include an antibacterial agent. For example, a PMP composition including an antibiotic as described herein can be administered to an animal in an amount and for a time sufficient to: reach a target level (e.g., a predetermined or threshold level) of antibiotic concentration inside or on the animal; and/or treat or prevent a bacterial infection in the animal. The antibacterials described herein may be formulated in a PMP composition for any of the methods described herein, and in certain instances, may be associated with the PMP thereof. In some instances, the PMP compositions includes two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different antibacterial agents.

As used herein, the term “antibacterial agent” refers to a material that kills or inhibits the growth, proliferation, division, reproduction, or spread of bacteria, such as phytopathogenic bacteria, and includes bactericidal (e.g., disinfectant compounds, antiseptic compounds, or antibiotics) or bacteriostatic agents (e.g., compounds or antibiotics). Bactericidal antibiotics kill bacteria, while bacteriostatic antibiotics only slow their growth or reproduction.

Bactericides can include disinfectants, antiseptics, or antibiotics. The most used disinfectants can comprise: active chlorine (i.e., hypochlorites (e.g., sodium hypochlorite), chloramines, dichloroisocyanurate and trichloroisocyanurate, wet chlorine, chlorine dioxide etc.), active oxygen (peroxides, such as peracetic acid, potassium persulfate, sodium perborate, sodium percarbonate and urea perhydrate), iodine (iodpovidone (povidone-iodine, Betadine), Lugol's solution, iodine tincture, iodinated nonionic surfactants), concentrated alcohols (mainly ethanol, 1-propanol, called also n-propanol and 2-propanol, called isopropanol and mixtures thereof; further, 2-phenoxyethanol and 1- and 2-phenoxypropanols are used), phenolic substances (such as phenol (also called carbolic acid), cresols (called Lysole in combination with liquid potassium soaps), halogenated (chlorinated, brominated) phenols, such as hexachlorophene, triclosan, trichlorophenol, tribromophenol, pentachlorophenol, Dibromol and salts thereof), cationic surfactants, such as some quaternary ammonium cations (such as benzalkonium chloride, cetyl trimethylammonium bromide or chloride, didecyldimethylammonium chloride, cetylpyridinium chloride, benzethonium chloride) and others, non-quaternary compounds, such as chlorhexidine, glucoprotamine, octenidine dihydrochloride etc.), strong oxidizers, such as ozone and permanganate solutions; heavy metals and their salts, such as colloidal silver, silver nitrate, mercury chloride, phenylmercury salts, copper sulfate, copper oxide-chloride, copper hydroxide, copper octanoate, copper oxychloride sulfate, copper sulfate, copper sulfate pentahydrate, etc. Heavy metals and their salts are the most toxic, and environment-hazardous bactericides and therefore, their use is strongly oppressed or canceled; further, also properly concentrated strong acids (phosphoric, nitric, sulfuric, amidosulfuric, toluenesulfonic acids) and alkalis (sodium, potassium, calcium hydroxides). As antiseptics (i.e., germicide agents that can be used on human or animal body, skin, mucoses, wounds and the like), few of the above mentioned disinfectants can be used, under proper conditions (mainly concentration, pH, temperature and toxicity toward man/animal). Among them, important are: properly diluted chlorine preparations (i.e., Daquin's solution, 0.5% sodium or potassium hypochlorite solution, pH-adjusted to pH 7-8, or 0.5-1% solution of sodium benzenesulfochloramide (chloramine B)), some iodine preparations, such as iodopovidone in various galenics (ointment, solutions, wound plasters), in the past also Lugol's solution, peroxides as urea perhydrate solutions and pH-buffered 0.1-0.25% peracetic acid solutions, alcohols with or without antiseptic additives, used mainly for skin antisepsis, weak organic acids such as sorbic acid, benzoic acid, lactic acid and salicylic acid some phenolic compounds, such as hexachlorophene, triclosan and Dibromol, and cation-active compounds, such as 0.05-0.5% benzalkonium, 0.5-4% chlorhexidine, 0.1-2% octenidine solutions.

The PMP composition described herein may include an antibiotic. Any antibiotic known in the art may be used. Antibiotics are commonly classified based on their mechanism of action, chemical structure, or spectrum of activity.

The antibiotic described herein may target any bacterial function or growth processes and may be either bacteriostatic (e.g., slow or prevent bacterial growth) or bactericidal (e.g., kill bacteria). In some instances, the antibiotic is a bactericidal antibiotic. In some instances, the bactericidal antibiotic is one that targets the bacterial cell wall (e.g., penicillins and cephalosporins); one that targets the cell membrane (e.g., polymyxins); or one that inhibits essential bacterial enzymes (e.g., rifamycins, lipiarmycins, quinolones, and sulfonamides). In some instances, the bactericidal antibiotic is an aminoglycoside (e.g., kasugamycin). In some instances, the antibiotic is a bacteriostatic antibiotic. In some instances the bacteriostatic antibiotic targets protein synthesis (e.g., macrolides, lincosamides, and tetracyclines). Additional classes of antibiotics that may be used herein include cyclic lipopeptides (such as daptomycin), glycylcyclines (such as tigecycline), oxazolidinones (such as linezolid), or lipiarmycins (such as fidaxomicin). Examples of antibiotics include rifampicin, ciprofloxacin, doxycycline, ampicillin, and polymyxin B. The antibiotic described herein may have any level of target specificity (e.g., narrow- or broad-spectrum). In some instances, the antibiotic is a narrow-spectrum antibiotic, and thus targets specific types of bacteria, such as gram-negative or gram-positive bacteria. Alternatively, the antibiotic may be a broad-spectrum antibiotic that targets a wide range of bacteria.

Examples of antibacterial agents suitable for the treatment of animals include Penicillins (Amoxicillin, Ampicillin, Bacampicillin, Carbenicillin, Cloxacillin, Dicloxacillin, Flucloxacillin, Mezlocillin, Nafcillin, Oxacillin, Penicillin G, Crysticillin 300 A.S., Pentids, Permapen, Pfizerpen, Pfizerpen-AS, Wycillin, Penicillin V, Piperacillin, Pivampicillin, Pivmecillinam, Ticarcillin), Cephalosporins (Cefacetrile (cephacetrile), Cefadroxil (cefadroxyl), Cefalexin (cephalexin), Cefaloglycin (cephaloglycin), Cefalonium (cephalonium), Cefaloridine (cephaloradine), Cefalotin (cephalothin), Cefapirin (cephapirin), Cefatrizine, Cefazaflur, Cefazedone, Cefazolin (cephazolin), Cefradine (cephradine), Cefroxadine, Ceftezole, Cefaclor, Cefamandole, Cefmetazole, Cefonicid, Cefotetan, Cefoxitin, Cefprozil (cefproxil), Cefuroxime, Cefuzonam, Cefcapene, Cefdaloxime, Cefdinir, Cefditoren, Cefetamet, Cefixime, Cefmenoxime, Cefodizime, Cefotaxime, Cefpimizole, Cefpodoxime, Cefteram, Ceftibuten, Ceftiofur, Ceftiolene, Ceftizoxime, Ceftriaxone, Cefoperazone, Ceftazidime, Cefclidine, Cefepime, Cefluprenam, Cefoselis, Cefozopran, Cefpirome, Cefquinome, Ceftobiprole, Ceftaroline, Cefaclomezine, Cefaloram, Cefaparole, Cefcanel, Cefedrolor, Cefempidone, Cefetrizole, Cefivitril, Cefmatilen, Cefmepidium, Cefovecin, Cefoxazole, Cefrotil, Cefsumide, Cefuracetime, Ceftioxide, Combinations, Ceftazidime/Avibactam, Ceftolozane/Tazobactam), Monobactams (Aztreonam), Carbapenems (Imipenem, Imipenem/cilastatin, Doripenem, Ertapenem, Meropenem, Meropenem/vaborbactam), Macrolide (Azithromycin, Erythromycin, Clarithromycin, Dirithromycin, Roxithromycin, Telithromycin), Lincosamides (Clindamycin, Lincomycin), Streptogramins (Pristinamycin, Quinupristin/dalfopristin), Aminoglycoside (Amikacin, Gentamicin, Kanamycin, Neomycin, Netilmicin, Paromomycin, Streptomycin, Tobramycin), Quinolone (Flumequine, Nalidixic acid, Oxolinic acid, Piromidic acid, Pipemidic acid, Rosoxacin, Second Generation, Ciprofloxacin, Enoxacin, Lomefloxacin, Nadifloxacin, Norfloxacin, Ofloxacin, Pefloxacin, Rufloxacin, Balofloxacin, Gatifloxacin, Grepafloxacin, Levofloxacin, Moxifloxacin, Pazufloxacin, Sparfloxacin, Temafloxacin, Tosufloxacin, Besifloxacin, Delafloxacin, Clinafloxacin, Gemifloxacin, Prulifloxacin, Sitafloxacin, Trovafloxacin), Sulfonamides (Sulfamethizole, Sulfamethoxazole, Sulfisoxazole, Trimethoprim-Sulfamethoxazole), Tetracycline (Demeclocycline, Doxycycline, Minocycline, Oxytetracycline, Tetracycline, Tigecycline), Other (Lipopeptides, Fluoroquinolone, Lipoglycopeptides, Cephalosporin, Macrocyclics, Chloramphenicol, Metronidazole, Tinidazole, Nitrofurantoin, Glycopeptides, Vancomycin, Teicoplanin, Lipoglycopeptides, Telavancin, Oxazolidinones, Linezolid, Cycloserine 2, Rifamycins, Rifampin, Rifabutin, Rifapentine, Rifalazil, Polypeptides, Bacitracin, Polymyxin B, Tuberactinomycins, Viomycin, Capreomycin).

One skilled in the art will appreciate that a suitable concentration of each antibiotic in the composition depends on factors such as efficacy, stability of the antibiotic, number of distinct antibiotics, the formulation, and methods of application of the composition.

ii. Antifungal Agents

The PMP compositions described herein can further include an antifungal agent. For example, a PMP composition including an antifungal as described herein can be administered to an animal in an amount and for a time sufficient to reach a target level (e.g., a predetermined or threshold level) of antifungal concentration inside or on the animal; and/or treat or prevent a fungal infection in the animal. The antifungals described herein may be formulated in a PMP composition for any of the methods described herein, and in certain instances, may be associated with the PMP thereof. In some instances, the PMP compositions includes two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different antifungal agents.

As used herein, the term “fungicide” or “antifungal agent” refers to a substance that kills or inhibits the growth, proliferation, division, reproduction, or spread of fungi, such as fungi that are pathogenic to animals. Many different types of antifungal agent have been produced commercially. Non limiting examples of antifungal agents include: Allylamines (Amorolfin, Butenafine, Naftifine, Terbinafine), Imidazoles ((Bifonazole, Butoconazole, Clotrimazole, Econazole, Fenticonazole, Ketoconazole, Isoconazole, Luliconazole, Miconazole, Omoconazole, Oxiconazole, Sertaconazole, Sulconazole, Tioconazole, Terconazole); Triazoles (Albaconazole, Efinaconazole, Fluconazole, Isavuconazole, Itraconazole, Posaconazole, Ravuconazole, Terconazole, Voriconazole), Thiazoles (Abafungin), Polyenes (Amphotericin B, Nystatin, Natamycin, Trichomycin), Echinocandins (Anidulafungin, Caspofungin, Micafungin), Other (Tolnaftate, Flucytosine, Butenafine, Griseofulvin, Ciclopirox, Selenium sulfide, Tavaborole). One skilled in the art will appreciate that a suitable concentration of each antifungal in the composition depends on factors such as efficacy, stability of the antifungal, number of distinct antifungals, the formulation, and methods of application of the composition.

iii. Insecticides

The PMP compositions described herein can further include an insecticide. For example, the insecticide can decrease the fitness of (e.g., decrease growth or kill) an insect vector of an animal pathogen. A PMP composition including an insecticide as described herein can be contacted with an insect, in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of insecticide concentration inside or on the insect; and (b) decrease fitness of the insect. In some instances, the insecticide can decrease the fitness of (e.g., decrease growth or kill) a parasitic insect. A PMP composition including an insecticide as described herein can be contacted with a parasitic insect, or an animal infected therewith, in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of insecticide concentration inside or on the parasitic insect; and (b) decrease the fitness of the parasitic insect. The insecticides described herein may be formulated in a PMP composition for any of the methods described herein, and in certain instances, may be associated with the PMP thereof. In some instances, the PMP compositions include two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different insecticide agents.

As used herein, the term “insecticide” or “insecticidal agent” refers to a substance that kills or inhibits the growth, proliferation, reproduction, or spread of insects, such as insect vectors of animal pathogens or parasitic insects. Non limiting examples of insecticides are shown in Table 4. Additional non-limiting examples of suitable insecticides include biologics, hormones or pheromones such as azadirachtin, Bacillus species, Beauveria species, codlemone, Metarrhizium species, Paecilomyces species, thuringiensis, and Verticillium species, and active compounds having unknown or non-specified mechanisms of action such as fumigants (such as aluminium phosphide, methyl bromide and sulphuryl fluoride) and selective feeding inhibitors (such as cryolite, flonicamid and pymetrozine). One skilled in the art will appreciate that a suitable concentration of each insecticide in the composition depends on factors such as efficacy, stability of the insecticide, number of distinct insecticides, the formulation, and methods of application of the composition.

The PMP compositions described herein can further include a nematicide. In some instances, the PMP composition includes two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different nematicides. For example, the nematicide can decrease the fitness of (e.g., decrease growth or kill) a parasitic nematode. A PMP composition including a nematicide as described herein can be contacted with a parasitic nematode, or an animal infected therewith, in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of nematicide concentration inside or on the target nematode; and (b) decrease fitness of the parasitic nematode. The nematicides described herein may be formulated in a PMP composition for any of the methods described herein, and in certain instances, may be associated with the PMP thereof.

As used herein, the term “nematicide” or “nematicidal agent” refers to a substance that kills or inhibits the growth, proliferation, reproduction, or spread of nematodes, such as a parasitic nematode. Non limiting examples of nematicides are shown in Table 5. One skilled in the art will appreciate that a suitable concentration of each nematicide in the composition depends on factors such as efficacy, stability of the nematicide, number of distinct nematicides, the formulation, and methods of application of the composition.

The PMP compositions described herein can further include an antiparasitic agent. For example, the antiparasitic can decrease the fitness of (e.g., decrease growth or kill) a parasitic protozoan. A PMP composition including an antiparasitic as described herein can be contacted with a protozoan in an amount and for a time sufficient to: (a) reach a target level (e.g., a predetermined or threshold level) of antiparasitic concentration inside or on the protozoan, or animal infected therewith; and (b) decrease fitness of the protozoan. This can be useful in the treatment or prevention of parasites in animals. For example, a PMP composition including an antiparasitic agent as described herein can be administered to an animal in an amount and for a time sufficient to: reach a target level (e.g., a predetermined or threshold level) of antiparasitic concentration inside or on the animal; and/or treat or prevent a parasite (e.g., parasitic nematode, parasitic insect, or protozoan) infection in the animal. The antiparasitic described herein may be formulated in a PMP composition for any of the methods described herein, and in certain instances, may be associated with the PMP thereof. In some instances, the PMP composition includes two or more (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10) different antiparasitic agents.

As used herein, the term “antiparasitic” or “antiparasitic agent” refers to a substance that kills or inhibits the growth, proliferation, reproduction, or spread of parasites, such as parasitic protozoa, parasitic nematodes, or parasitic insects. Examples of antiparasitic agents include Antihelmintics (Bephenium, Diethylcarbamazine, Ivermectin, Niclosamide, Piperazine, Praziquantel, Pyrantel, Pyrvinium, Benzimidazoles, Albendazole, Flubendazole, Mebendazole, Thiabendazole, Levamisole, Nitazoxanide, Monopantel, Emodepside, Spiroindoles), Scabicides (Benzyl benzoate, Benzyl benzoate/disulfiram, Lindane, Malathion, Permethrin), Pediculicides (Piperonyl butoxide/pyrethrins, Spinosad, Moxidectin), Scabicides (Crotamiton), Anticestodes (Niclosamide, Pranziquantel, Albendazole), Antiamoebics (Rifampin, Apmphotericin B); or Antiprotozoals (Melarsoprol, Eflornithine, Metronidazole, Tinidazole, Miltefosine, Artemisinin). In certain instances, the antiparasitic agent may be use for treating or prevening infections in livestock animals, e.g., Levamisole, Fenbendazole, Oxfendazole, Albendazole, Moxidectin, Eprinomectin, Doramectin, Ivermectin, or Clorsulon. One skilled in the art will appreciate that a suitable concentration of each antiparasitic in the composition depends on factors such as efficacy, stability of the antiparasitic, number of distinct antiparasitics, the formulation, and methods of application of the composition.

III. Methods of Use

The PMPs manufactured herein are useful in a variety of agricultural or therapeutic methods. Examples of methods of using PMPs are described further below.

A. Delivery to a Plant

Provided herein are methods of delivering a PMP composition (e.g., manufactured in accordance with the methods or bioreactors herein) to a plant, e.g., by contacting the plant, or part thereof, with the PMP composition. In some instances, plants may be treated with unloaded PMPs. In other instances, the PMPs include a heterologous functional agent, e.g., pesticidal agents (e.g., antibacterial agents, antifungal agents, nematicides, molluscicides, virucides, herbicides), pest control agents (e.g., repellents), fertilizing agents, or plant-modifying agents. PMPs intended for delivery to a plant may be formulated with an agriculturally acceptable carrier, e.g., formulated for delivery to a plant.

In one aspect, provided herein is a method of increasing the fitness of a plant, the method including delivering to the plant the PMP composition described herein (e.g., in an effective amount and duration) to increase the fitness of the plant relative to an untreated plant (e.g., a plant that has not been delivered the PMP composition).

An increase in the fitness of the plant as a consequence of delivery of a PMP composition can manifest in a number of ways, e.g., thereby resulting in a better production of the plant, for example, an improved yield, improved vigor of the plant or quality of the harvested product from the plant. An improved yield of a plant relates to an increase in the yield of a product (e.g., as measured by plant biomass, grain, seed or fruit yield, protein content, carbohydrate or oil content or leaf area) of the plant by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without the application of the instant compositions or compared with application of conventional agricultural agents. For example, yield can be increased by at least about 0.5%, about 1%, about 2%, about 3%, about 4%, about 5%, about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, about 100%, or more than 100%. Yield can be expressed in terms of an amount by weight or volume of the plant or a product of the plant on some basis. The basis can be expressed in terms of time, growing area, weight of plants produced, or amount of a raw material used. For example, such methods may increase the yield of plant tissues including, but not limited to: seeds, fruits, kernels, bolls, tubers, roots, and leaves.

An increase in the fitness of a plant as a consequence of delivery of a PMP composition can also be measured by other methods, such as an increase or improvement of the vigor rating, the stand (the number of plants per unit of area), plant height, stalk circumference, stalk length, leaf number, leaf size, plant canopy, visual appearance (such as greener leaf color), root rating, emergence, protein content, increased tillering, bigger leafs, more leaves, less dead basal leaves, stronger tillers, less fertilizer needed, less seeds needed, more productive tillers, earlier flowering, early grain or seed maturity, less plant verse (lodging), increased shoot growth, earlier germination, or any combination of these factors, by a measurable or noticeable amount over the same factor of the plant produced under the same conditions, but without the administration of the instant compositions or with application of conventional agricultural agents.

Provided herein is a method of modifying or increasing the fitness of a plant, the method including delivering to the plant an effective amount of a PMP composition provided herein, wherein the method modifies the plant and thereby introduces or increases a beneficial trait in the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) relative to an untreated plant. In particular, the method may increase the fitness of the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) relative to an untreated plant.

In some instances, the increase in plant fitness is an increase (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) in disease resistance, drought tolerance, heat tolerance, cold tolerance, salt tolerance, metal tolerance, herbicide tolerance, chemical tolerance, water use efficiency, nitrogen utilization, resistance to nitrogen stress, nitrogen fixation, pest resistance, herbivore resistance, pathogen resistance, yield, yield underwater-limited conditions, vigor, growth, photosynthetic capability, nutrition, protein content, carbohydrate content, oil content, biomass, shoot length, root length, root architecture, seed weight, or amount of harvestable produce.

In some instances, the increase in fitness is an increase (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) in development, growth, yield, resistance to abiotic stressors, or resistance to biotic stressors. An abiotic stress refers to an environmental stress condition that a plant or a plant part is subjected to that includes, e.g., drought stress, salt stress, heat stress, cold stress, and low nutrient stress. A biotic stress refers to an environmental stress condition that a plant or plant part is subjected to that includes, e.g. nematode stress, insect herbivory stress, fungal pathogen stress, bacterial pathogen stress, or viral pathogen stress. The stress may be temporary, e.g. several hours, several days, several months, or permanent, e.g. for the life of the plant.

In some instances, the increase in plant fitness is an increase (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) in quality of products harvested from the plant. For example, the increase in plant fitness may be an improvement in commercially favorable features (e.g., taste or appearance) of a product harvested from the plant. In other instances, the increase in plant fitness is an increase in shelf-life of a product harvested from the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%).

Alternatively, the increase in fitness may be an alteration of a trait that is beneficial to human or animal health, such as a reduction in allergen production. For example, the increase in fitness may be a decrease (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) in production of an allergen (e.g., pollen) that stimulates an immune response in an animal (e.g., human).

The modification of the plant (e.g., increase in fitness) may arise from modification of one or more plant parts. For example, the plant can be modified by contacting leaf, seed, pollen, root, fruit, shoot, flower, cells, protoplasts, or tissue (e.g., meristematic tissue) of the plant. As such, in another aspect, provided herein is a method of increasing the fitness of a plant, the method including contacting pollen of the plant with an effective amount of a PMP composition herein, wherein the method increases the fitness of the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) relative to an untreated plant.

In yet another aspect, provided herein is a method of increasing the fitness of a plant, the method including contacting a seed of the plant with an effective amount of a PMP composition disclosed herein, wherein the method increases the fitness of the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) relative to an untreated plant.

In another aspect, provided herein is a method including contacting a protoplast of the plant with an effective amount of a PMP composition herein, wherein the method increases the fitness of the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) relative to an untreated plant.

In a further aspect, provided herein is a method of increasing the fitness of a plant, the method including contacting a plant cell of the plant with an effective amount of a PMP composition herein, wherein the method increases the fitness of the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) relative to an untreated plant.

In another aspect, provided herein is a method of increasing the fitness of a plant, the method including contacting meristematic tissue of the plant with an effective amount of a PMP composition herein, wherein the method increases the fitness of the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) relative to an untreated plant.

In another aspect, provided herein is a method of increasing the fitness of a plant, the method including contacting an embryo of the plant with an effective amount of a PMP composition herein, wherein the method increases the fitness of the plant (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100%) relative to an untreated plant.

In cases where an herbicide is included in the PMP, or compositions thereof, the methods may be further used to decrease the fitness of or kill weeds. In such instances, the method may be effective to decrease the fitness of the weed by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more in comparison to an untreated weed (e.g., a weed to which the PMP composition has not been administered). For example, the method may be effective to kill the weed, thereby decreasing a population of the weed by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more in comparison to an untreated weed. In some instances, the method substantially eliminates the weed. Examples of weeds that can be treated in accordance with the present methods are further described herein.

The details of each of these methods are described further below.

B. Delivery to a Plant Pest

Provided herein are methods of delivering a PMP composition (e.g., manufactured in accordance with the methods or bioreactors herein) to a plant pest, e.g., by contacting the plant pest with the PMP composition. In some instances, plant pest may be treated with unloaded PMPs. In other instances, the PMPs include a heterologous functional agent, e.g., pesticidal agents (e.g., antibacterial agents, antifungal agents, nematicides, molluscicides, virucides, or herbicides) or pest control agents (e.g., repellents). For example, the methods can be useful for decreasing the fitness of a pest, e.g., to prevent or treat a pest infestation as a consequence of delivery of a PMP composition.

In one aspect, provided herein is a method of decreasing the fitness of a pest, the method including delivering to the pest the PMP composition described herein (e.g., in an effective amount and for an effective duration) to decrease the fitness of the pest relative to an untreated pest (e.g., a pest that has not been delivered the PMP composition).

In one aspect, provided herein is a method of decreasing a fungal infection in (e.g., treating) a plant having a fungal infection, wherein the method includes delivering to the plant pest a PMP composition including a plurality of PMPs (e.g., a PMP composition described herein).

In another aspect, provided herein is a method of decreasing a fungal infection in (e.g., treating) a plant having a fungal infection, wherein the method includes delivering to the plant pest a PMP composition including a plurality of PMPs (e.g., a PMP composition described herein), and wherein the plurality of PMPs include an antifungal agent. In some instances, the antifungal agent is a nucleic acid that inhibits expression of a gene (e.g., dc/1 and dc/2 (i.e., dc/1/2) in a fungus that causes the fungal infection. In some instances, the fungal infection is caused be a fungus belonging to a Sclerotinia spp. (e.g., Sclerotinia sclerotiorum), a Botrytis spp. (e.g., Botrytis cinerea), an Aspergillus spp., a Fusarium spp., or a Penicillium spp. In some instances, the composition includes a PMP produced from an Arabidopsis apoplast EV.

In some instances, the weed is an Indian goosegrass (Eleusine indica). In some instances, the method decreases the fitness of the weed relative to an untreated weed.

A decrease in the fitness of the pest as a consequence of delivery of a PMP composition can manifest in a number of ways. In some instances, the decrease in fitness of the pest may manifest as a deterioration or decline in the physiology of the pest (e.g., reduced health or survival) as a consequence of delivery of the PMP composition. In some instances, the fitness of an organism may be measured by one or more parameters, including, but not limited to, reproductive rate, fertility, lifespan, viability, mobility, fecundity, pest development, body weight, metabolic rate or activity, or survival in comparison to a pest to which the PMP composition has not been administered. For example, the methods or compositions provided herein may be effective to decrease the overall health of the pest or to decrease the overall survival of the pest. In some instances, the decreased survival of the pest is about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% greater relative to a reference level (e.g., a level found in a pest that does not receive a PMP composition). In some instances, the methods and compositions are effective to decrease pest reproduction (e.g., reproductive rate, fertility) in comparison to a pest to which the PMP composition has not been administered. In some instances, the methods and compositions are effective to decrease other physiological parameters, such as mobility, body weight, life span, fecundity, or metabolic rate, by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a pest that does not receive a PMP composition).

In some instances, the decrease in pest fitness may manifest as a decrease in the production of one or more nutrients in the pest (e.g., vitamins, carbohydrates, amino acids, or polypeptides) in comparison to a pest to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to decrease the production of nutrients in the pest (e.g., vitamins, carbohydrates, amino acids, or polypeptides) by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a pest that does not receive a PMP composition).

In some instances, the decrease in pest fitness may manifest as an increase in the pest's sensitivity to a pesticidal agent and/or a decrease in the pest's resistance to a pesticidal agent in comparison to a pest to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to increase the pest's sensitivity to a pesticidal agent by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a pest that does not receive a PMP composition). The pesticidal agent may be any pesticidal agent known in the art, including insecticidal agents. In some instances, the methods or compositions provided herein may increase the pest's sensitivity to a pesticidal agent by decreasing the pest's ability to metabolize or degrade the pesticidal agent into usable substrates in comparison to a pest to which the PMP composition has not been administered.

In some instances, the decrease in pest fitness may manifest as an increase in the pest's sensitivity to an allelochemical agent and/or a decrease in the pest's resistance to an allelochemical agent in comparison to a pest to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to decrease the pest's resistance to an allelochemical agent by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a pest that does not receive a PMP composition). In some instances, the allelochemical agent is caffeine, soyacystatin, fenitrothion, monoterpenes, diterpene acids, or phenolic compounds (e.g., tannins, flavonoids). In some instances, the methods or compositions provided herein may increase the pest's sensitivity to an allelochemical agent by decreasing the pest's ability to metabolize or degrade the allelochemical agent into usable substrates in comparison to a pest to which the PMP composition has not been administered.

In some instances, the methods or compositions provided herein may be effective to decease the pest's resistance to parasites or pathogens (e.g., fungal, bacterial, or viral pathogens or parasites) in comparison to a pest to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to decrease the pest's resistance to a pathogen or parasite (e.g., fungal, bacterial, or viral pathogens; or parasitic mites) by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a pest that does not receive a PMP composition).

In some instances, the methods or compositions provided herein may be effective to decrease the pest's ability to carry or transmit a plant pathogen (e.g., plant virus (e.g., TYLCV) or a plant bacterium (e.g., Agrobacterium spp)) in comparison to a pest to which the PMP composition has not been administered. For example, the methods or compositions provided herein may be effective to decrease the pest's ability to carry or transmit a plant pathogen (e.g., a plant virus (e.g., TYLCV) or plant bacterium (e.g., Agrobacterium spp)) by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a pest that does not receive a PMP composition).

Additionally or alternatively, in cases where an herbicide is included in the PMP, or compositions thereof, the methods may be further used to decrease the fitness of or kill weeds. In such instances, the method may be effective to decrease the fitness of the weed by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more in comparison to an untreated weed (e.g., a weed to which the PMP composition has not been administered). For example, the method may be effective to kill the weed, thereby decreasing a population of the weed by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more in comparison to an untreated weed. In some instances, the method substantially eliminates the weed. Examples of weeds that can be treated in accordance with the present methods are further described herein.

In some instances, the decrease in pest fitness may manifest as other fitness disadvantages, such as a decreased tolerance to certain environmental factors (e.g., a high or low temperature tolerance), a decreased ability to survive in certain habitats, or a decreased ability to sustain a certain diet in comparison to a pest to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to decrease pest fitness in any plurality of ways described herein. Further, the PMP composition may decrease pest fitness in any number of pest classes, orders, families, genera, or species (e.g., 1 pest species, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 200, 250, 500, or more pest species). In some instances, the PMP composition acts on a single pest class, order, family, genus, or species.

Pest fitness may be evaluated using any standard methods in the art. In some instances, pest fitness may be evaluated by assessing an individual pest. Alternatively, pest fitness may be evaluated by assessing a pest population. For example, a decrease in pest fitness may manifest as a decrease in successful competition against other insects, thereby leading to a decrease in the size of the pest population.

ii. Bacteria

The PMP compositions and related methods can be useful for decreasing the fitness of a bacterium, e.g., to prevent or treat a bacterial infection in a plant. Included are methods for delivering a PMP composition to a bacterium by contacting the bacteria with the PMP composition. Additionally or alternatively, the methods include delivering the biopesticide to a plant at risk of or having a bacterial infection, by contacting the plant with the PMP composition.

The PMP compositions and related methods are suitable for delivery to bacteria, or a plant infected therewith, including any bacteria described further below. For example, the bacteria may be one belonging to Actinobacteria or Proteobacteria, such as bacteria in the families of the Burkholderiaceae, Xanthomonadaceae, Pseudomonadaceae, Enterobacteriaceae, Microbacteriaceae, and Rhizobiaceae.

iii. Insects

The PMP compositions and related methods can be useful for decreasing the fitness of an insect, e.g., to prevent or treat an insect infestation in a plant. The term “insect” includes any organism belonging to the phylum Arthropoda and to the class Insecta or the class Arachnida, in any stage of development, i.e., immature and adult insects. Included are methods for delivering a PMP composition to an insect by contacting the insect with the PMP composition. Additionally or alternatively, the methods include delivering the biopesticide to a plant at risk of or having an insect infestation, by contacting the plant with the PMP composition.

iv. Mollusks

The PMP compositions and related methods can be useful for decreasing the fitness of a mollusk, e.g., to prevent or treat a mollusk infestation in a plant. The term “mollusk” includes any organism belonging to the phylum Mollusca. Included are methods for delivering a PMP composition to a mollusk by contacting the mollusk with the PMP composition. Additionally or alternatively, the methods include delivering the biopesticide to a plant at risk of or having a mollusk infestation, by contacting the plant with the PMP composition.

The PMP compositions and related methods are suitable for preventing or treating infestation by terrestrial Gastropods (e.g., slugs and snails) in agriculture and horticulture. They include all terrestrial slugs and snails which mostly occur as polyphagous pests on agricultural and horticultural crops. For example, the mollusk may belong to the family Achatinidae, Agriolimacidae, Ampullariidae, Arionidae, Bradybaenidae, Helicidae, Hydromiidae, Lymnaeidae, Milacidae, Urocyclidae, or Veronicellidae.

For example, in some instances, the mollusk is Achatina spp., Archachatina spp. (e.g., Archachatina marginata), Agriolimax spp., Anon spp. (e.g., A. ater, A. circumscriptus, A. distinctus, A. fasciatus, A. hortensis, A. intermedius, A. rufus, A. subfuscus, A. silvaticus, A. lusitanicus), Arliomax spp. (e.g., Ariolimax columbianus), Biomphalaria spp., Bradybaena spp. (e.g., B. fruticum), Bulinus spp., Cantareus spp. (e.g., C. asperses), Cepaea spp. (e.g., C. hortensis, C. nemoralis, C. hortensis), Cernuella spp., Cochlicella spp., Cochlodina spp. (e.g., C. laminata), Deroceras spp. (e.g., D. agrestis, D. empiricorum, D. laeve, D. panornimatum, D. reticulatum), Discus spp. (e.g., D. rotundatus), Euomphalia spp., Galba spp. (e.g., G. trunculata), Helicella spp. (e.g., H. itala, H. obvia), Helicigona spp. (e.g., H. arbustorum), Helicodiscus spp., Helix spp. (e.g., H. aperta, H. aspersa, H. pomatia), Limax spp. (e.g., L. cinereoniger, L. flavus, L. marginatus, L. maximus, L. tenellus), Limicolaria spp. (e.g., Limicolaria aurora), Lymnaea spp. (e.g., L. stagnalis), Mesodon spp. (e.g., Meson thyroidus), Monadenia spp. (e.g., Monadenia fidelis), Milax spp. (e.g., M. gagates, M. marginatus, M. sowerbyi, M. budapestensis), Oncomelania spp., Neohelix spp. (e.g., Neohelix albolabris), Opeas spp., Otala spp. (e.g., Otala lacteal), Oxyloma spp. (e.g., O. pfeiffen), Pomacea spp. (e.g., P. canaliculata), Succinea spp., Tandonia spp. (e.g., T. budapestensis, T. sowerbyi), Theba spp., Vallonia spp., or Zonitoides spp. (e.g., Z. nitidus).

v. Nematodes

The PMP compositions and related methods can be useful for decreasing the fitness of a nematode, e.g., to prevent or treat a nematode infestation in a plant. The term “nematode” includes any organism belonging to the phylum Nematoda. Included are methods for delivering a PMP composition to a nematode by contacting the nematode with the PMP composition. Additionally or alternatively, the methods include delivering the biopesticide to a plant at risk of or having a nematode infestation, by contacting the plant with the PMP composition.

The PMP compositions and related methods are suitable for preventing or treating infestation by nematodes that cause damage plants including, for example, Meloidogyne spp. (root-knot), Heterodera spp., Globodera spp., Pratylenchus spp., Helicotylenchus spp., Radopholus similis, Ditylenchus dipsaci, Rotylenchulus reniformis, Xiphinema spp., Aphelenchoides spp. and Belonolaimus longicaudatus. In some instances, the nematode is a plant parasitic nematodes or a nematode living in the soil. Plant parasitic nematodes include, but are not limited to, ectoparasites such as Xiphinema spp., Longidorus spp., and Trichodorus spp.; semiparasites such as Tylenchulus spp.; migratory endoparasites such as Pratylenchus spp., Radopholus spp., and Scutellonema spp.; sedentary parasites such as Heterodera spp., Globodera spp., and Meloidogyne spp., and stem and leaf endoparasites such as Ditylenchus spp., Aphelenchoides spp., and Hirshmaniella spp. Especially harmful root parasitic soil nematodes are such as cystforming nematodes of the genera Heterodera or Globodera, and/or root knot nematodes of the genus Meloidogyne. Harmful species of these genera are for example Meloidogyne incognita, Heterodera glycines (soybean cyst nematode), Globodera pallida and Globodera rostochiensis (potato cyst nematode), which species are effectively controlled with the PMP compositions described herein. However, the use of the PMP compositions described herein is in no way restricted to these genera or species, but also extends in the same manner to other nematodes.

Provided herein are methods of delivering to a plant symbiont a PMP composition disclosed herein. Included are methods for delivering a PMP composition to a symbiont (e.g., a bacterial endosymbiont, a fungal endosymbiont, or an insect) by contacting the symbiont with a PMP composition. The methods can be useful for increasing the fitness of plant symbiont, e.g., a symbiont that is beneficial to the fitness of a plant. In some instances, plant symbiont may be treated with unloaded PMPs. In other instances, the PMPs include a heterologous functional agent, e.g., fertilizing agents.

As such, the methods can be used to increase the fitness of a plant symbiont. In one aspect, provided herein is a method of increasing the fitness of a symbiont, the method including delivering to the symbiont the PMP composition described herein (e.g., in an effective amount and for an effective duration) to increase the fitness of the symbiont relative to an untreated symbiont (e.g., a symbiont that has not been delivered the PMP composition).

In one aspect, provided herein is a method of increasing the fitness of a fungus (e.g., a fungal endosymbiont of a plant), wherein the method includes delivering to the endosymbiont a PMP composition including a plurality of PMPs (e.g., a PMP composition described herein). For example, the plant symbiont may be an endosymbiotic fungus, such as a fungus of the genus Aspergillaceae, Ceratobasidiaceae, Coniochaetaceae, Cordycipitaceae, Corticiaceae, Cystofilobasidiaceae, Davidiellaceae, Debaryomycetaceae, Dothioraceae, Erysiphaceae, Filobasidiaceae, Glomerellaceae, Hydnaceae, Hypocreaceae, Leptosphaeriaceae, Montagnulaceae, Mortierellaceae, Mycosphaerellaceae, Nectriaceae, Orbiliaceae, Phaeosphaeriaceae, Pleosporaceae, Pseudeurotiaceae, Rhizopodaceae, Sclerotiniaceae, Stereaceae, or Trichocomacea.

In another aspect, provided herein is a method of increasing the fitness of a bacterium (e.g., a bacterial endosymbiont of a plant), wherein the method includes delivering to the bacteria a PMP composition including a plurality of PMPs (e.g., a PMP composition described herein). For example, the plant symbiont may be an endosymbiotic bacteria, such as a bacterium of the genus Acetobacteraceae, Acidobacteriaceae, Acidothermaceae, Aerococcaceae, Alcaligenaceae, Alicyclobacillaceae, Alteromonadaceae, Anaerolineaceae, Aurantimonadaceae, Bacillaceae, Bacteriovoracaceae, Bdellovibrionaceae, Bradyrhizobiaceae, Brevibacteriaceae, Brucellaceae, Burkholderiaceae, Carboxydocellaceae, Caulobacteraceae, Cellulomonadaceae, Chitinophagaceae, Chromatiaceae, Chthoniobacteraceae, Chthonomonadaceae, Clostridiaceae, Comamonadaceae, Corynebacteriaceae, Coxiellaceae, Cryomorphaceae, Cyclobacteriaceae, Cytophagaceae, Deinococcaceae, Dermabacteraceae, Dermacoccaceae, Enterobacteriaceae, Enterococcaceae, Erythrobacteraceae, Fibrobacteraceae, Flammeovirgaceae, Flavobacteriaceae, Frankiaceae, Fusobacteriaceae, Gaiellaceae, Gemmatimonadaceae, Geodermatophilaceae, Gly corny cetaceae, Haliangiaceae, Halomonadaceae, Holosporaceae, Hyphomicrobiaceae, lamiaceae, Intrasporangiaceae, Kineosporiaceae, Koribacteraceae, Lachnospiraceae, Lactobacillaceae, Legionellaceae, Leptospiraceae, Leuconostocaceae, Methylobacteriaceae, Methylocystaceae, Methylophilaceae, Microbacteriaceae, Micrococcaceae, Micromonosporaceae, Moraxellaceae, Mycobacteriaceae, Mycoplasmataceae, Myxococcaceae, Nakamurellaceae, Neisseriaceae, Nitrosomonadaceae, Nocardiaceae, Nocardioidaceae, Oceanospirillaceae, Opitutaceae, Oxalobacteraceae, Paenibacillaceae, Parachlamydiaceae, Pasteurellaceae, Patulibacteraceae, Peptostreptococcaceae, Phyllobacteriaceae, Piscirickettsiaceae, Planctomycetaceae, Planococcaceae, Polyangiaceae, Porphyromonadaceae, Prevotellaceae, Promicromonosporaceae, Pseudomonadaceae, Pseudonocardiaceae, Rhizobiaceae, Rhodobacteraceae, Rhodospirillaceae, Roseiflexaceae, Rubrobacteriaceae, Sandaracinaceae, Sanguibacteraceae, Saprospiraceae, Segniliparaceae, Shewanellaceae, Sinobacteraceae, Solibacteraceae, Solimonadaceae, Solirubrobacteraceae, Sphingobacteriaceae, Sphingomonadaceae, Spiroplasmataceae, Sporichthyaceae, Sporolactobacillaceae, Staphylococcaceae, Streptococcaceae, Streptomycetaceae, Syntrophobacteraceae, Veillonellaceae, Verrucomicrobiaceae, Weeksellaceae, Xanthobacteraceae, or Xanthomonadaceae.

In yet another aspect, provided herein is a method of increasing the fitness of an insect (e.g., an insect symbiont of a plant), wherein the method includes delivering to the insect a PMP composition including a plurality of PMPs (e.g., a PMP composition described herein). In some instances, the insect is a plant pollinator. For example, the insect may be of the genus Hymenoptera or Diptera. In some instances, the insect of the genus Hymenoptera is a bee. In other instances, the insect of the genus Diptera is a fly.

In some instances, the increase in symbiont fitness may manifest as an improvement in the physiology of the symbiont (e.g., improved health or survival) as a consequence of administration of the PMP composition. In some instances, the fitness of an organism may be measured by one or more parameters, including, but not limited to, reproductive rate, lifespan, mobility, fecundity, body weight, metabolic rate or activity, or survival in comparison to a symbiont to which the PMP composition has not been delivered. For example, the methods or compositions provided herein may be effective to improve the overall health of the symbiont or to improve the overall survival of the symbiont in comparison to a symbiont organism to which the PMP composition has not been administered. In some instances, the improved survival of the symbiont is about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% greater relative to a reference level (e.g., a level found in a symbiont that does not receive a PMP composition). In some instances, the methods and compositions are effective to increase symbiont reproduction (e.g., reproductive rate) in comparison to a symbiont organism to which the PMP composition has not been administered. In some instances, the methods and compositions are effective to increase other physiological parameters, such as mobility, body weight, life span, fecundity, or metabolic rate, by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a symbiont that does not receive a PMP composition).

In some instances, the increase in symbiont fitness may manifest as an increase in the frequency or efficacy of a desired activity carried out by the symbiont (e.g., pollination, predation on pests, seed spreading, or breakdown of waste or organic material) in comparison to a symbiont organism to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to increase the frequency or efficacy of a desired activity carried out by the symbiont (e.g., pollination, predation on pests, seed spreading, or breakdown of waste or organic material) by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a symbiont that does not receive a PMP composition).

In some instances, the increase in symbiont fitness may manifest as an increase in the production of one or more nutrients in the symbiont (e.g., vitamins, carbohydrates, amino acids, or polypeptides) in comparison to a symbiont organism to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to increase the production of nutrients in the symbiont (e.g., vitamins, carbohydrates, amino acids, or polypeptides) by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a symbiont that does not receive a PMP composition). In some instances, the methods or compositions provided herein may increase nutrients in an associated plant by increasing the production or metabolism of nutrients by one or more microorganisms (e.g., endosymbiont) in the symbiont.

In some instances, the increase in symbiont fitness may manifest as a decrease in the symbiont's sensitivity to a pesticidal agent and/or an increase in the symbiont's resistance to a pesticidal agent in comparison to a symbiont organism to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to decrease the symbiont's sensitivity to a pesticidal agent by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a symbiont that does not receive a PMP composition).

In some instances, the increase in symbiont fitness may manifest as a decrease in the symbiont's sensitivity to an allelochemical agent and/or an increase in the symbiont's resistance to an allelochemical agent in comparison to a symbiont organism to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to increase the symbiont's resistance to an allelochemical agent by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a symbiont that does not receive a PMP composition). In some instances, the allelochemical agent is caffeine, soyacystatin N, monoterpenes, diterpene acids, or phenolic compounds. In some instances, the methods or compositions provided herein may decrease the symbiont's sensitivity to an allelochemical agent by increasing the symbiont's ability to metabolize or degrade the allelochemical agent into usable substrates.

In some instances, the methods or compositions provided herein may be effective to increase the symbiont's resistance to parasites or pathogens (e.g., fungal, bacterial, or viral pathogens; or parasitic mites (e.g., Varroa destructor mite in honeybees)) in comparison to a symbiont organism to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to increase the symbiont's resistance to a pathogen or parasite (e.g., fungal, bacterial, or viral pathogens; or parasitic mites (e.g., Varroa destructor mite in honeybees)) by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a symbiont that does not receive a PMP composition).

In some instances, the increase in symbiont fitness may manifest as other fitness advantages, such as improved tolerance to certain environmental factors (e.g., a high or low temperature tolerance), improved ability to survive in certain habitats, or an improved ability to sustain a certain diet (e.g., an improved ability to metabolize soy vs corn) in comparison to a symbiont organism to which the PMP composition has not been administered. In some instances, the methods or compositions provided herein may be effective to increase symbiont fitness in any plurality of ways described herein. Further, the PMP composition may increase symbiont fitness in any number of symbiont classes, orders, families, genera, or species (e.g., 1 symbiont species, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 200, 250, 500, or more symbiont species). In some instances, the PMP composition acts on a single symbiont class, order, family, genus, or species.

Symbiont fitness may be evaluated using any standard methods in the art. In some instances, symbiont fitness may be evaluated by assessing an individual symbiont. Alternatively, symbiont fitness may be evaluated by assessing a symbiont population. For example, an increase in symbiont fitness may manifest as an increase in successful competition against other insects, thereby leading to an increase in the size of the symbiont population.

D. Delivery to an Animal Pathogen

Provided herein are methods of delivering a PMP composition (e.g., manufactured in accordance with the methods or bioreactors herein) to an animal (e.g., human) pathogen, such as one disclosed herein, by contacting the pathogen with a PMP composition. As used herein the term “pathogen” refers to an organism, such as a microorganism or an invertebrate, which causes disease or disease symptoms in an animal by, e.g., (i) directly infecting the animal, (ii) by producing agents that causes disease or disease symptoms in an animal (e.g., bacteria that produce pathogenic toxins and the like), and/or (iii) that elicit an immune (e.g., inflammatory response) in animals (e.g., biting insects, e.g., bedbugs). As used herein, pathogens include, but are not limited to bacteria, protozoa, parasites, fungi, nematodes, insects, viroids and viruses, or any combination thereof, wherein each pathogen is capable, either by itself or in concert with another pathogen, of eliciting disease or symptoms in animals, such as humans.

In some instances, animal (e.g., human) pathogen may be treated with unloaded PMPs. In other instances, the PMPs include a heterologous functional agent, e.g., a heterologous therapeutic agent (e.g., antibacterial agent, antifungal agent, insecticide, nematicide, antiparasitic agent, antiviral agent, or a repellent). The methods can be useful for decreasing the fitness of an animal pathogen, e.g., to prevent or treat a pathogen infection or control the spread of a pathogen as a consequence of delivery of the PMP composition.

Examples of pathogens that can be targeted in accordance with the methods described herein include bacteria (e.g., Streptococcus spp., Pneumococcus spp., Pseudomonas spp., Shigella spp, Salmonella spp., Campylobacter spp., or an Escherichia spp), fungi (Saccharomyces spp. or a Candida spp), parasitic insects (e.g., Cimex spp), parasitic nematodes (e.g., Heligmosomoides spp), or parasitic protozoa (e.g., Trichomoniasis spp).

For example, provided herein is a method of decreasing the fitness of a pathogen, the method including delivering to the pathogen a PMP composition described herein, wherein the method decreases the fitness of the pathogen relative to an untreated pathogen. In some embodiments, the method includes delivering the composition to at least one habitat where the pathogen grows, lives, reproduces, feeds, or infests. In some instances of the methods described herein, the composition is delivered as a pathogen comestible composition for ingestion by the pathogen. In some instances of the methods described herein, the composition is delivered (e.g., to a pathogen) as a liquid, a solid, an aerosol, a paste, a gel, or a gas.

Also provided herein is a method of decreasing the fitness of a parasitic insect, wherein the method includes delivering to the parasitic insect a PMP composition including a plurality of PMPs. In some instances, the method includes delivering to the parasitic insect a PMP composition including a plurality of PMPs, wherein the plurality of PMPs includes an insecticidal agent. For example, the parasitic insect may be a bedbug. Other non-limiting examples of parasitic insects are provided herein. In some instances, the method decreases the fitness of the parasitic insect relative to an untreated parasitic insect.

Additionally provided herein is a method of decreasing the fitness of a parasitic nematode, wherein the method includes delivering to the parasitic nematode a PMP composition including a plurality of PMPs. In some instances, the method includes delivering to the parasitic nematode a PMP composition including a plurality of PMPs, wherein the plurality of PMPs includes a nematicidal agent. For example, the parasitic nematode is Heligmosomoides polygyrus. Other non-limiting examples of parasitic nematodes are provided herein. In some instances, the method decreases the fitness of the parasitic nematode relative to an untreated parasitic nematode.

Further provided herein is a method of decreasing the fitness of a parasitic protozoan, wherein the method includes delivering to the parasitic protozoan a PMP composition including a plurality of PMPs. In some instances, the method includes delivering to the parasitic protozoan a PMP composition including a plurality of PMPs, wherein the plurality of PMPs includes an antiparasitic agent. For example, the parasitic protozoan may be T. vaginalis. Other non-limiting examples of parasitic protozoans are provided herein. In some instances, the method decreases the fitness of the parasitic protozoan relative to an untreated parasitic protozoan.

A decrease in the fitness of the pathogen as a consequence of delivery of a PMP composition can manifest in a number of ways. In some instances, the decrease in fitness of the pathogen may manifest as a deterioration or decline in the physiology of the pathogen (e.g., reduced health or survival) as a consequence of delivery of the PMP composition. In some instances, the fitness of an organism may be measured by one or more parameters, including, but not limited to, reproductive rate, fertility, lifespan, viability, mobility, fecundity, pathogen development, body weight, metabolic rate or activity, or survival in comparison to a pathogen to which the PMP composition has not been administered. For example, the methods or compositions provided herein may be effective to decrease the overall health of the pathogen or to decrease the overall survival of the pathogen. In some instances, the decreased survival of the pathogen is about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% greater relative to a reference level (e.g., a level found in a pathogen that does not receive a PMP composition. In some instances, the methods and compositions are effective to decrease pathogen reproduction (e.g., reproductive rate, fertility) in comparison to a pathogen to which the PMP composition has not been administered. In some instances, the methods and compositions are effective to decrease other physiological parameters, such as mobility, body weight, life span, fecundity, or metabolic rate, by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a pathogen that does not receive a PMP composition).

In some instances, the decrease in pest fitness may manifest as an increase in the pathogen's sensitivity to an antipathogen agent and/or a decrease in the pathogen's resistance to an antipathogen agent in comparison to a pathogen to which the PMP composition has not been delivered. In some instances, the methods or compositions provided herein may be effective to increase the pathogen's sensitivity to a pesticidal agent by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a pest that does not receive a PMP composition).

In some instances, the decrease in pathogen fitness may manifest as other fitness disadvantages, such as a decreased tolerance to certain environmental factors (e.g., a high or low temperature tolerance), a decreased ability to survive in certain habitats, or a decreased ability to sustain a certain diet in comparison to a pathogen to which the PMP composition has not been delivered. In some instances, the methods or compositions provided herein may be effective to decrease pathogen fitness in any plurality of ways described herein. Further, the PMP composition may decrease pathogen fitness in any number of pathogen classes, orders, families, genera, or species (e.g., 1 pathogen species, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 200, 250, 500, or more pathogen species). In some instances, the PMP composition acts on a single pest class, order, family, genus, or species.

Pathogen fitness may be evaluated using any standard methods in the art. In some instances, pest fitness may be evaluated by assessing an individual pathogen.

As used herein, the term “vector” refers to an insect that can carry or transmit an animal pathogen from a reservoir to an animal. Exemplary vectors include insects, such as those with piercing-sucking mouthparts, as found in Hemiptera and some Hymenoptera and Diptera such as mosquitoes, bees, wasps, midges, lice, tsetse fly, fleas and ants, as well as members of the Arachnidae such as ticks and mites.

In some instances, the vector of the animal (e.g., human) pathogen may be treated with unloaded PMPs. In other instances, the PMPs include a heterologous functional agent, e.g., a heterologous therapeutic agent (e.g., antibacterial agent, antifungal agent, insecticide, nematicide, antiparasitic agent, antiviral agent, or a repellent). The methods can be useful for decreasing the fitness of a pathogen vector, e.g., to control the spread of a pathogen as a consequence of delivery of the PMP composition. Examples of pathogen vectors that can be targeted in accordance with the present methods include insects, such as those described herein.

For example, provided herein is a method of decreasing the fitness of an animal pathogen vector, the method including delivering to the vector an effective amount of the PMP compositions described herein, wherein the method decreases the fitness of the vector relative to an untreated vector. In some instances, the method includes delivering the composition to at least one habitat where the vector grows, lives, reproduces, feeds, or infests. In some instances, the composition is delivered as a comestible composition for ingestion by the vector. In some instances, the vector is an insect. In some instances, the insect is a mosquito, a tick, a mite, or a louse. In some instances, the composition is delivered (e.g., to the pathogen vector) as a liquid, a solid, an aerosol, a paste, a gel, or a gas.

For example, provided herein is a method of decreasing the fitness of an insect vector of an animal pathogen, wherein the method includes delivering to the vector a PMP composition including a plurality of PMPs. In some instances, the method includes delivering to the vector a PMP composition including a plurality of PMPs, wherein the plurality of PMPs includes an insecticidal agent. For example, the insect vector may be a mosquito, tick, mite, or louse. Other non-limiting examples of pathogen vectors are provided herein. In some instances, the method decreases the fitness of the vector relative to an untreated vector.

In some instances, the decrease in vector fitness may manifest as a deterioration or decline in the physiology of the vector (e.g., reduced health or survival) as a consequence of administration of a composition. In some instances, the fitness of an organism may be measured by one or more parameters, including, but not limited to, reproductive rate, lifespan, mobility, fecundity, body weight, metabolic rate or activity, or survival in comparison to a vector organism to which the composition has not been delivered. For example, the methods or compositions provided herein may be effective to decrease the overall health of the vector or to decrease the overall survival of the vector. In some instances, the decreased survival of the vector is about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% greater relative to a reference level (e.g., a level found in a vector that does not receive a composition). In some instances, the methods and compositions are effective to decrease vector reproduction (e.g., reproductive rate) in comparison to a vector organism to which the composition has not been delivered. In some instances, the methods and compositions are effective to decrease other physiological parameters, such as mobility, body weight, life span, fecundity, or metabolic rate, by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a vector that is not delivered the composition).

In some instances, the decrease in vector fitness may manifest as an increase in the vector's sensitivity to a pesticidal agent and/or a decrease in the vector's resistance to a pesticidal agent in comparison to a vector organism to which the composition has not been delivered. In some instances, the methods or compositions provided herein may be effective to increase the vector's sensitivity to a pesticidal agent by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or greater than 100% relative to a reference level (e.g., a level found in a vector that does not receive a composition). The pesticidal agent may be any pesticidal agent known in the art, including insecticidal agents. In some instances, the methods or compositions provided herein may increase the vector's sensitivity to a pesticidal agent by decreasing the vector's ability to metabolize or degrade the pesticidal agent into usable substrates in comparison to a vector to which the composition has not been delivered.

In some instances, the decrease in vector fitness may manifest as other fitness disadvantages, such as decreased tolerance to certain environmental factors (e.g., a high or low temperature tolerance), decreased ability to survive in certain habitats, or a decreased ability to sustain a certain diet in comparison to a vector organism to which the composition has not been delivered. In some instances, the methods or compositions provided herein may be effective to decrease vector fitness in any plurality of ways described herein. Further, the composition may decrease vector fitness in any number of vector classes, orders, families, genera, or species (e.g., 1 vector species, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 200, 250, 500, or more vector species). In some instances, the composition acts on a single vector class, order, family, genus, or species.

Vector fitness may be evaluated using any standard methods in the art. In some instances, vector fitness may be evaluated by assessing an individual vector. Alternatively, vector fitness may be evaluated by assessing a vector population. For example, a decrease in vector fitness may manifest as a decrease in successful competition against other vectors, thereby leading to a decrease in the size of the vector population.

By decreasing the fitness of vectors that carry animal pathogens, the compositions provided herein are effective to reduce the spread of vector-borne diseases. The composition may be delivered to the insects using any of the formulations and delivery methods described herein, in an amount and for a duration effective to reduce transmission of the disease, e.g., reduce vertical or horizontal transmission between vectors and/or reduce transmission to animals. For example, the composition described herein may reduce vertical or horizontal transmission of a vector-borne pathogen by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more in comparison to a vector organism to which the composition has not been delivered. As another example, the composition described herein may reduce vectorial competence of an insect vector by about 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more in comparison to a vector organism to which the composition has not been delivered.

F. Application Methods

A plant described herein can be exposed to a PMP composition described herein in any suitable manner that permits delivering or administering the composition to the plant. The PMP composition may be delivered either alone or in combination with other active (e.g., fertilizing agents) or inactive substances and may be applied by, for example, spraying, injection (e.g., microinjection), through plants, pouring, dipping, in the form of concentrated liquids, gels, solutions, suspensions, sprays, powders, pellets, briquettes, bricks and the like, formulated to deliver an effective concentration of the PMP composition. Amounts and locations for application of the compositions described herein are generally determined by the habitat of the plant, the lifecycle stage at which the plant can be targeted by the PMP composition, the site where the application is to be made, and the physical and functional characteristics of the PMP composition.

In some instances, the composition is sprayed directly onto a plant e.g., crops, by e.g., backpack spraying, aerial spraying, crop spraying/dusting etc. In instances where the PMP composition is delivered to a plant, the plant receiving the PMP composition may be at any stage of plant growth. For example, formulated PMP compositions can be applied as a seed-coating or root treatment in early stages of plant growth or as a total plant treatment at later stages of the crop cycle. In some instances, the PMP composition may be applied as a topical agent to a plant.

Further, the PMP composition may be applied (e.g., in the soil in which a plant grows, or in the water that is used to water the plant) as a systemic agent that is absorbed and distributed through the tissues of a plant. In some instances, plants or food organisms may be genetically transformed to express the PMP composition.

Delayed or continuous release can also be accomplished by coating the PMP composition or a composition with the PMP composition(s) with a dissolvable or bioerodable coating layer, such as gelatin, which coating dissolves or erodes in the environment of use, to then make the PMP composition available, or by dispersing the agent in a dissolvable or erodable matrix. Such continuous release and/or dispensing devices may be advantageously employed to consistently maintain an effective concentration of one or more of the PMP compositions described herein.

In some instances, the PMP composition is delivered to a part of the plant, e.g., a leaf, seed, pollen, root, fruit, shoot, or flower, or a tissue, cell, or protoplast thereof. In some instances, the PMP composition is delivered to a cell of the plant. In some instances, the PMP composition is delivered to a protoplast of the plant. In some instances, the PMP composition is delivered to a tissue of the plant. For example, the composition may be delivered to meristematic tissue of the plant (e.g., apical meristem, lateral meristem, or intercalary meristem). In some instances, the composition is delivered to permanent tissue of the plant (e.g., simple tissues (e.g., parenchyma, collenchyma, or sclerenchyma) or complex permanent tissue (e.g., xylem or phloem)). In some instances, the composition is delivered to a plant embryo.

In some instances, the PMP composition may be recommended for field application as an amount of PMPs per hectare (g/ha or kg/ha) or the amount of active ingredient (e.g., PMP with or without a heterologous functional agent) or acid equivalent per hectare (kg a.i./ha or g a.i./ha). In some instances, a lower amount of heterologous functional agent in the present compositions may be required to be applied to soil, plant media, seeds plant tissue, or plants to achieve the same results as where the heterologous functional agent is applied in a composition lacking PMPs. For example, the amount of heterologous functional agent may be applied at levels about 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 50, or 100-fold (or any range between about 2 and about 100-fold, for example about 2- to 10-fold; about 5- to 15-fold, about 10- to 20-fold; about 10- to 50-fold) less than the same heterologous functional agent applied in a non-PMP composition, e.g., direct application of the same heterologous functional agent without PMPs. PMP compositions of the invention can be applied at a variety of amounts per hectare, for example at about 0.0001, 0.001, 0.005, 0.01, 0.1, 1, 2, 10, 100, 1,000, 2,000, 5,000 (or any range between about 0.0001 and 5,000) kg/ha.

As used herein, the term “treatment” refers to administering a pharmaceutical composition to an animal for prophylactic and/or therapeutic purposes. To “prevent” refers to prophylactic treatment of an animal who is not yet ill, but who is susceptible to, or otherwise at risk of, a particular disease. To “treat” refers to administering treatment to an animal already suffering from a disease to improve or stabilize the animal's condition. The present methods involve delivering the PMP compositions described herein to an animal, such as a human.

For example, provided herein is a method of treating an animal having a fungal infection, wherein the method includes administering to the animal an effective amount of a PMP composition including a plurality of PMPs. In some instances, the method includes administering to the animal an effective amount of a PMP composition including a plurality of PMPs, wherein the plurality of PMPs includes an antifungal agent. In some instances, the antifungal agent is a nucleic acid that inhibits expression of a gene in a fungus that causes the fungal infection (e.g., Enhanced Filamentous Growth Protein (EFG1)). In some instances, the fungal infection is caused by Candida albicans. In some instances, composition includes a PMP produced from an Arabidopsis apoplast EV. In some instances, the method decreases or substantially eliminates the fungal infection.

In another aspect, provided herein is a method of treating an animal having a bacterial infection, wherein the method includes administering to the animal an effective amount of a PMP composition including a plurality of PMPs.

The present methods are useful to treat an infection (e.g., as caused by an animal pathogen) in an animal, which refers to administering treatment to an animal already suffering from a disease to improve or stabilize the animal's condition. This may involve reducing colonization of a pathogen in, on, or around an animal by one or more pathogens (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%) relative to a starting amount and/or allow benefit to the individual (e.g., reducing colonization in an amount sufficient to resolve symptoms). In such instances, a treated infection may manifest as a decrease in symptoms (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%). In some instances, a treated infection is effective to increase the likelihood of survival of an individual (e.g., an increase in likelihood of survival by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%) or increase the overall survival of a population (e.g., an increase in likelihood of survival by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%). For example, the compositions and methods may be effective to “substantially eliminate” an infection, which refers to a decrease in the infection in an amount sufficient to sustainably resolve symptoms (e.g., for at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 months) in the animal.

The present methods are useful to prevent an infection (e.g., as caused by an animal pathogen), which refers to preventing an increase in colonization in, on, or around an animal by one or more pathogens (e.g., by about 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, or more than 100% relative to an untreated animal) in an amount sufficient to maintain an initial pathogen population (e.g., approximately the amount found in a healthy individual), prevent the onset of an infection, and/or prevent symptoms or conditions associated with infection. For example, individuals may receive prophylaxis treatment to prevent a fungal infection while being prepared for an invasive medical procedure (e.g., preparing for surgery, such as receiving a transplant, stem cell therapy, a graft, a prosthesis, receiving long-term or frequent intravenous catheterization, or receiving treatment in an intensive care unit), in immunocompromised individuals (e.g., individuals with cancer, with HIV/AIDS, or taking immunosuppressive agents), or in individuals undergoing long term antibiotic therapy.

The PMP composition can be formulated for administration or administered by any suitable method, including, for example, intravenously, intramuscularly, subcutaneously, intradermally, percutaneously, intraarterially, intraperitoneally, intralesionally, intracranially, intraarticularly, intraprostatically, intrapleurally, intratracheally, intrathecally, intranasally, intravaginally, intrarectally, topically, intratumorally, peritoneally, subconjunctivally, intravesicularly, mucosally, intrapericardially, intraumbilically, intraocularly, intraorbitally, orally, topically, transdermally, intravitreally (e.g., by intravitreal injection), by eye drop, by inhalation, by injection, by implantation, by infusion, by continuous infusion, by localized perfusion bathing target cells directly, by catheter, by lavage, in cremes, or in lipid compositions. Oral administration includes delivery of the compositions in food or animal feed, accordingly, the invention includes food and feed compositions comprising the PMP compositions described herein. The compositions utilized in the methods described herein can also be administered systemically or locally. The method of administration can vary depending on various factors (e.g., the compound or composition being administered and the severity of the condition, disease, or disorder being treated). In some instances, PMP composition is administered intravenously, intramuscularly, subcutaneously, topically, orally, transdermally, intraperitoneally, intraorbitally, by implantation, by inhalation, intrathecally, intraventricularly, or intranasally. Dosing can be by any suitable route, e.g., by injections, such as intravenous or subcutaneous injections, depending in part on whether the administration is brief or chronic. Various dosing schedules including but not limited to single or multiple administrations over various time-points, bolus administration, and pulse infusion are contemplated herein.

For the prevention or treatment of an infection or disease or disorder described herein, use of a PMP composition (when used alone or in combination with one or more other additional therapeutic agents) will depend on the type of disease to be treated, the severity and course of the disease, whether the administration for preventive or therapeutic purposes, previous therapy, the patient's clinical history and response to the PMP composition. The PMP composition can be, e.g., administered to the patient at one time or over a series of treatments. For repeated administrations over several days or longer, depending on the condition, the treatment would generally be sustained until a desired suppression of disease symptoms occurs or the infection is no longer detectable. Such doses may be administered intermittently, e.g., every week or every two weeks (e.g., such that the patient receives, for example, from about two to about twenty, doses of the PMP composition. An initial higher loading dose, followed by one or more lower doses may be administered. However, other dosage regimens may be useful. The progress of this therapy is easily monitored by conventional techniques and assays.

In some instances, the amount of the PMP composition administered to individual (e.g., human) may be in the range of about 0.01 mg/kg to about 5 g/kg (e.g., about 0.01 mg/kg-0.1 mg/kg, about 0.1 mg/kg-1 mg/kg, about 1 mg/kg-10 mg/kg, about 10 mg/kg-100 mg/kg, about 100 mg/kg-1 g/kg, or about 1 g/kg-5 g/kg), of the individual's body weight. In some instances, the amount of the PMP composition administered to individual (e.g., human) is at least 0.01 mg/kg (e.g., at least 0.01 mg/kg, at least 0.1 mg/kg, at least 1 mg/kg, at least 10 mg/kg, at least 100 mg/kg, at least 1 g/kg, or at least 5 g/kg), of the individual's body weight. The dose may be administered as a single dose or as multiple doses (e.g., 2, 3, 4, 5, 6, 7, or more than 7 doses). In some instances, the PMP composition administered to the animal may be administered alone or in combination with an additional therapeutic agent. The dose of the antibody administered in a combination treatment may be reduced as compared to a single treatment. The progress of this therapy is easily monitored by conventional techniques.

The seeds are vernalized for 2 d at 4° C. before being moved to short-day conditions (9-h days, 22° C., 150 μEm⁻²). After 1 week, the seedlings are transferred to Pro-Mix PGX. Plants are grown for 4-6 weeks before harvest.

PMPs are isolated from the apoplastic wash of 4-6-week old Arabidopsis rosettes, as described by Rutter and Innes, Plant Physiol. 173(1): 728-741, 2017. Briefly, whole rosettes are harvested at the root and vacuum infiltrated with vesicle isolation buffer (20 mM MES, 2 mM CaCl2), and 0.1 M NaCl, pH6). Infiltrated plants are carefully blotted to remove excess fluid, placed inside 30-mL syringes, and centrifuged in 50 mL conical tubes at 700 g for 20 min at 2° C. to collect the apoplast extracellular fluid containing EVs. Next, the apoplast extracellular fluid is filtered through a 0.85 μm filter to remove large particles, and PMPs are purified as described in Example 2.

b) PMP Isolation from the Apoplast of Sunflower Seeds

Intact sunflower seeds (H. annuus L.), and are imbibed in water for 2 hours, peeled to remove the pericarp, and the apoplastic extracellular fluid is extracted by a modified vacuum infiltration-centrifugation procedure, adapted from Regente et al, FEBS Letters. 583: 3363-3366, 2009. Briefly, seeds are immersed in vesicle isolation buffer (20 mM MES, 2 mM CaCl₂), and 0.1 M NaCl, pH6) and subjected to three vacuum pulses of 10 s, separated by 30 s intervals at a pressure of 45 kPa. The infiltrated seeds are recovered, dried on filter paper, placed in fritted glass filters and centrifuged for 20 min at 400 g at 4° C. The apoplast extracellular fluid is recovered, filtered through a 0.85 μm filter to remove large particles, and PMPs are purified as described in Example 2.

c) PMP Isolation from Ginger Roots

Fresh ginger (Zingiber officinale) rhizome roots are purchased from a local supplier and washed 3× with PBS. A total of 200 grams of washed roots is ground in a mixer (Osterizer 12-speed blender) at the highest speed for 10 min (pause 1 min for every 1 min of blending), and PMPs are isolated as described in Zhuang et al., J Extracellular Vesicles. 4(1):28713, 2015. Briefly, ginger juice is sequentially centrifuged at 1,000 g for 10 min, 3,000 g for 20 min and 10,000 g for 40 min to remove large particles from the PMP-containing supernatant. PMPs are purified as described in Example 2.

d) PMP Isolation from Grapefruit Juice

Fresh grapefruits (Citrus x paradisi) are purchased from a local supplier, their skins are removed, and the fruit is manually pressed, or ground in a mixer (Osterizer 12-speed blender) at the highest speed for 10 min (pause 1 min for every minute of blending) to collect the juice, as described by Wang et al., Molecular Therapy. 22(3): 522-534, 2014 with minor modifications. Briefly, juice/juice pulp is sequentially centrifuged at 1,000 g for 10 min, 3,000 g for 20 min, and 10,000 g for 40 min to remove large particles from the PMP-containing supernatant. PMPs are purified as described in Example 2.

e) PMP Isolation from Broccoli Heads

Broccoli (Brassica oleracea var. italica) PMPs are isolated as previously described (Deng et al., Molecular Therapy, 25(7): 1641-1654, 2017). Briefly, fresh broccoli is purchased from a local supplier, washed three times with PBS, and ground in a mixer (Osterizer 12-speed blender) at the highest speed for 10 min (pause 1 min for every minute of blending). Broccoli juice is then sequentially centrifuged at 1,000 g for 10 min, 3,000 g for 20 min, and 10,000 g for 40 min to remove large particles from the PMP-containing supernatant. PMPs are purified as described in Example 2.

f) PMP Isolation from Olive Pollen

Olive (Olea europaea) pollen PMPs are isolated as previously described in Prado et al., Molecular Plant. 7(3):573-577, 2014. Briefly, olive pollen (0.1 g) is hydrated in a humid chamber at room temperature for 30 min before transferring to petri dishes (15 cm in diameter) containing 20 ml germination medium: 10% sucrose, 0.03% Ca(NO₃)₂, 0.01% KNO₃, 0.02% MgSO₄, and 0.03% H₃BO₃. Pollen is germinated at 30° C. in the dark for 16 h. Pollen grains are considered germinated only when the tube is longer than the diameter of the pollen grain. Cultured medium containing PMPs is collected and cleared of pollen debris by two successive filtrations on 0.85 um filters by centrifugation. PMPs are purified as described in Example 2.

g) PMP Isolation from Arabidopsis Phloem Sap

Arabidopsis (Arabidopsis thaliana Col-0) seeds are surface sterilized with 50% bleach and plated on 0.53 Murashige and Skoog medium containing 0.8% agar. The seeds are vernalized for 2 d at 4° C. before being moved to short-day conditions (9-h days, 22° C., 150 μEm⁻²). After 1 week, the seedlings are transferred to Pro-Mix PGX. Plants are grown for 4-6 weeks before harvest.

Phloem sap from 4-6-week old Arabidopsis rosette leaves is collected as described by Tetyuk et al., JoVE. 80, 2013. Briefly, leaves are cut at the base of the petiole, stacked, and placed in a reaction tube containing 20 mM K2-EDTA for one hour in the dark to prevent sealing of the wound. Leaves are gently removed from the container, washed thoroughly with distilled water to remove all EDTA, put in a clean tube, and phloem sap is collected for 5-8 hours in the dark. Leaves are discarded, phloem sap is filtered through a 0.85 μm filter to remove large particles, and PMPs are purified as described in Example 2.

h) PMP Isolation from Tomato Plant Xylem Sap

Tomato (Solanum lycopersicum) seeds are planted in a single pot in an organic-rich soil, such as Sunshine Mix (Sun Gro Horticulture, Agawam, Mass.) and maintained in a greenhouse between 22° C. and 28° C. About two weeks after germination, at the two true-leaf stage, the seedlings are transplanted individually into pots (10 cm diameter and 17 cm deep) filled with sterile sandy soil containing 90% sand and 10% organic mix. Plants are maintained in a greenhouse at 22-28° C. for four weeks.

Xylem sap from 4-week old tomato plants is collected as described by Kohlen et al., Plant Physiology. 155(2):721-734, 2011. Briefly, tomato plants are decapitated above the hypocotyl, and a plastic ring is placed around the stem. The accumulating xylem sap is collected for 90 min after decapitation. Xylem sap is filtered through a 0.85 μm filter to remove large particles, and PMPs are purified as described in Example 2.

i) PMP Isolation from Tobacco BY-2 Cell Culture Medium

Tobacco BY-2 (Nicotiana tabacum L cv. Bright Yellow 2) cells are cultured in the dark at 26° C., on a shaker at 180 rpm in MS (Murashige and Skoog, 1962) BY-2 cultivation medium (pH 5.8) comprised MS salts (Duchefa, Haarlem, Netherlands, at #M0221) supplemented with 30 g/L sucrose, 2.0 mg/L potassium dihydrogen phosphate, 0.1 g/L myo-inositol, 0.2 mg/L 2,4-dichlorophenoxyacetic acid, and 1 mg/L thiamine HCl. The BY-2 cells are subcultured weekly by transferring 5% (v/v) of a 7-day-old cell culture into 100 mL fresh liquid medium. After 72-96 hours, BY-2 cultured medium is collected and centrifuged at 300 g at 4° C. for 10 minutes to remove cells. The supernatant containing PMPs is collected and cleared of debris by filtration on 0.85 um filter. PMPs are purified as described in Example 2.

Example 2: Production of Purified Plant Messenger Packs (PMPs)

In this example, purified PMPs are produced from crude PMP fractions as described in Example 1, using ultrafiltration combined with size-exclusion chromatography, a density gradient (iodixanol or sucrose), and the removal of aggregates by precipitation or size-exclusion chromatography.

Experimental Design:

a) Production of Purified Grapefruit PMPs Using Ultrafiltration Combined with Size-Exclusion Chromatography

The crude grapefruit PMP fraction from Example 1a is concentrated using 100-kDA molecular weight cut-off (MWCO) Amicon spin filter (Merck Millipore). Subsequently, the concentrated crude PMP solution is loaded onto a PURE-EV size exclusion chromatography column (HansaBioMed Life Sciences Ltd) and isolated according to the manufacturer's instructions. The purified PMP-containing fractions are pooled after elution. Optionally, PMPs can be further concentrated using a 100-kDa MWCO Amicon spin filter, or by Tangential Flow Filtration (TFF). The purified PMPs are analyzed as described in Example 3.

b) Production of Purified Arabidopsis Apoplast PMPs Using an Iodixanol Gradient

Crude Arabidopsis leaf apoplast PMPs are isolated as described in Example 1a, and purified PMPs are produced by using an iodixanol gradient as described in Rutter and Innes, Plant Physiol. 173(1): 728-741, 2017. To prepare discontinuous iodixanol gradients (OptiPrep; Sigma-Aldrich), solutions of 40% (v/v), 20% (v/v), 10% (v/v), and 5% (v/v) iodixanol are created by diluting an aqueous 60% OptiPrep stock solution in vesicle isolation buffer (VIB; 20 mM MES, 2 mM CaCl2, and 0.1 M NaCl, pH6). The gradient is formed by layering 3 ml of 40% solution, 3 mL of 20% solution, 3 mL of 10% solution, and 2 mL of 5% solution. The crude apoplast PMP solution from Example 1a is centrifuged at 40,000 g for 60 min at 4° C. The pellet is resuspended in 0.5 ml of VIB and layered on top of the gradient. Centrifugation is performed at 100,000 g for 17 h at 4° C. The first 4.5 ml at the top of the gradient is discarded, and subsequently 3 volumes of 0.7 ml that contain the apoplast PMPs are collected, brought up to 3.5 mL with VIB and centrifuged at 100,000 g for 60 min at 4° C. The pellets are washed with 3.5 ml of VIB and repelleted using the same centrifugation conditions. The purified PMP pellets are combined for subsequent analysis, as described in Example 3.

c) Production of Purified Grapefruit PMPs Using a Sucrose Gradient

Crude grapefruit juice PMPs are isolated as described in Example 1d, centrifuged at 150,000 g for 90 min, and the PMP-containing pellet is resuspended in 1 ml PBS as described (Mu et al., Molecular Nutrition & Food Research. 58(7):1561-1573, 2014). The resuspended pellet is transferred to a sucrose step gradient (8%/15%/30%/45%/60%) and centrifuged at 150,000 g for 120 min to produce purified PMPs. Purified grapefruit PMPs are harvested from the 30%/45% interface, and subsequently analyzed, as described in Example 3.

d) Removal of Aggregates from Grapefruit PMPs

In order to remove protein aggregates from produced grapefruit PMPs as described in Example 1d or purified PMPs from Example 2a-c, an additional purification step can be included. The produced PMP solution is taken through a range of pHs to precipitate protein aggregates in solution. The pH is adjusted to 3, 5, 7, 9, or 11 with the addition of sodium hydroxide or hydrochloric acid. pH is measured using a calibrated pH probe. Once the solution is at the specified pH, it is filtered to remove particulates. Alternatively, the isolated PMP solution can be flocculated using the addition of charged polymers, such as Polymin-P or Praestol 2640. Briefly, 2-5 g per L of Polymin-P or Praestol 2640 is added to the solution and mixed with an impeller. The solution is then filtered to remove particulates. Alternatively, aggregates are solubilized by increasing salt concentration. NaCl is added to the PMP solution until it is at 1 mol/L. The solution is then filtered to purify the PMPs. Alternatively, aggregates are solubilized by increasing the temperature. The isolated PMP mixture is heated under mixing until it has reached a uniform temperature of 50° C. for 5 minutes. The PMP mixture is then filtered to isolate the PMPs. Alternatively, soluble contaminants from PMP solutions are separated by size-exclusion chromatography column according to standard procedures, where PMPs elute in the first fractions, whereas proteins and ribonucleoproteins and some lipoproteins are eluted later. The efficiency of protein aggregate removal is determined by measuring and comparing the protein concentration before and after removal of protein aggregates via BCA/Bradford protein quantification. The produced PMPs are analyzed as described in Example 3.

Example 3: Plant Messenger Pack Characterization

This example describes the characterization of PMPs produced as described in Example 1 or Example 2.

Experimental Design:

a) Determining PMP Concentration

PMP particle concentration is determined by Nanoparticle Tracking Analysis (NTA) using a Malvern NanoSight, or by Tunable Resistive Pulse Sensing (TRPS) using an iZon qNano, following the manufacturer's instructions. The protein concentration of purified PMPs is determined by using the DC Protein assay (Bio-Rad). The lipid concentration of purified PMPs is determined using a fluorescent lipophilic dye, such as DiOC6 (ICN Biomedicals) as described by Rutter and Innes, Plant Physiol. 173(1): 728-741, 2017. Briefly, purified PMP pellets from Example 2 are resuspended in 100 ml of 10 mM DiOC6 (ICN Biomedicals) diluted with MES buffer (20 mM MES, pH 6) plus 1% plant protease inhibitor cocktail (Sigma-Aldrich) and 2 mM 2,29-dipyridyl disulfide. The resuspended PMPs are incubated at 37° C. for 10 min, washed with 3 mL of MES buffer, repelleted (40,000 g, 60 min, at 4° C.), and resuspended in fresh MES buffer. DiOC6 fluorescence intensity is measured at 485 nm excitation and 535 nm emission.

b) Biophysical and Molecular Characterization of PMPs

PMPs are characterized by electron and cryo-electron microscopy on a JEOL 1010 transmission electron microscope, following the protocol from Wu et al., Analyst. 140(2):386-406, 2015. The size and zeta potential of the PMPs are also measured using a Malvern Zetasizer or iZon qNano, following the manufacturer's instructions. Lipids are isolated from PMPs using chloroform extraction and characterized with LC-MS/MS as demonstrated in Xiao et al. Plant Cell. 22(10): 3193-3205, 2010. Glycosyl inositol phosphorylceramides (GIPCs) lipids are extracted and purified as described by Cacas et al., Plant Physiology. 170: 367-384, 2016, and analyzed by LC-MS/MS as described above. Total RNA, DNA, and protein are characterized using Quant-It kits from Thermo Fisher according to instructions. Proteins on the PMPs are characterized by LC-MS/MS following the protocol in Rutter and Innes, Plant Physiol. 173(1): 728-741, 2017. RNA and DNA are extracted using Trizol, prepared into libraries with the TruSeq Total RNA with Ribo-Zero Plant kit and the Nextera Mate Pair Library Prep Kit from Illumina, and sequenced on an Illumina MiSeq following manufacturer's instructions.

Example 4: Characterization of Plant Messenger Pack Stability

This example describes measuring the stability of PMPs under a wide variety of storage and physiological conditions.

Experimental Design:

PMPs produced as described in Examples 1 and 2 are subjected to various conditions. PMPs are suspended in water, 5% sucrose, or PBS and left for 1, 7, 30, and 180 days at −20° C., 4° C., 20° C., and 37° C. PMPs are also suspended in water and dried using a rotary evaporator system and left for 1, 7, and 30, and 180 days at 4° C., 20° C., and 37° C. PMPs are also suspended in water or 5% sucrose solution, flash-frozen in liquid nitrogen and lyophilized. After 1, 7, 30, and 180 days, dried and lyophilized PMPs are then resuspended in water. The previous three experiments with conditions at temperatures above 0° C. are also exposed to an artificial sunlight simulator in order to determine content stability in simulated outdoor UV conditions. PMPs are also subjected to temperatures of 37° C., 40° C., 45° C., 50° C., and 55° C. for 1, 6, and 24 hours in buffered solutions with a pH of 1, 3, 5, 7, and 9 with or without the addition of 1 unit of trypsin or in other simulated gastric fluids.

After each of these treatments, PMPs are bought back to 20° C., neutralized to pH 7.4, and characterized using some or all of the methods described in Example 3.

Example 5. Uptake of Pectinase-Treated PMPs by Alfalfa Sprouts

This example demonstrates that the removal of pectins during the PMP production process does not impact their in planta uptake and systemic transport. In this example, lemon PMPs were used as model PMPs, and Alfalfa sprouts were used as model plant.

a) Production of Lemon PMPs with or without the Addition of Pectinase

Lemons were obtained from a local market. Lemon juice (1260 ml) was collected using a juice press, and split into two fractions. 630 ml was untreated, and 630 ml was pH adjusted to pH4 with NaOH and incubated with 6 U/ml pectinase (Sigma, 17389) for 1.45 hrs at room temperature. Pectinase treated and untreated juice was subsequently centrifuged at 3000 g for 20 minutes, followed by 10,000 g for 40 minutes to remove large debris. Next, the processed juice was incubated with 500 mM EDTA pH8.6, to a final concentration of 50 mM EDTA, pH 7.19-7.25, for 30 minutes at room temperature to chelate calcium and prevent the formation of pectin macromolecules. Subsequently, the EDTA-treated juice was passaged through an 11 um, 1 um and 0.45 um filter to remove large particles. Filtered juice was washed (260 ml PBS during TFF procedure) and concentrated ˜1.6× to a total volume of 400 ml by Tangential Flow Filtration (TFF), and dialyzed overnight in PBS, pH 7.4 using a 300 kDa dialysis membrane. Subsequently, the dialyzed juice was further concentrated by TFF to a final concentration of 30 ml (˜21×). Next, we used size exclusion chromatography to elute the PMP-containing fractions, and analyzed the 280 nm absorbance (SpectraMax) to determine the PMP-containing fractions from late elution fractions containing contaminants. SEC fractions 4-6 (no pectinase treatment) and SEC fractions 4-7 (with pectinase treatment) containing purified PMPs were pooled together in the individual treatment groups. Pooled SEC fractions were dialyzed o/n in PBS, pH 7.4 using a 300 kDa dialysis membrane. Samples were sterilized by sequential filtration using 0.85 um, 0.4 um and 0.22 um syringe filters, and concentrated further by pelleting PMPs for 1.5 hrs at 40,000× g and finally the pellet is resuspended in Ultrapure water. The final PMP concentration for untreated lemon PMPs was 1.24×10¹² PMPs/ml and median PMP size was 129 nm+/−12 nm SD; for pectinase-treated lemon PMPs the final concentration was 2.2610¹² PMPs/ml and median PMP size was 130 nm+/−11 nm (SD), as determined by nano-flow cytometry (NanoFCM) using concentration and size standards provided by the manufacturer.

b) Labeling of Lemon PMPs with DyLight 800 NHS Ester

Pectinase treated and untreated lemon PMPs were labeled with the DyLight 800 NHS Ester (Life Technologies, #46421) covalent membrane dye (DyL800). Briefly, DyL800 was dissolved in DMSO to a final concentration of 10 mg/ml, 200 ul of PMPs were mixed with 5 ul dye, incubated for 1 h at room temperature on a shaker, and labeled PMPs were washed 2-3 times by ultracentrifugation at 100,000×g for 1 hr at 4° C. and pellets were resuspended with 1.5 ml UltraPure water. To control for the presence of potential dye aggregates, a dye-only control sample was prepared according to the same procedure, adding 200 ul of UltraPure water instead of PMPs. The final DyL800-labeled PMP pellet and DyL800 dye-only control were resuspended in a minimal amount of UltraPure water and characterized by NanoFCM. The final concentration of non-pectinase treated Dyl800-labeled lemon PMPs was 3.2×10¹² PMPs/ml, and of pectinase treated DyL800-labeled was 5.57×10¹² PMPs/ml. The labeling efficiency could not be determined using the nanoFCM, as it cannot detect infrared.

c) Treatment of Alfalfa Sprouts with Pectinase Treated and Untreated DyL800-PMPs

To assess whether the removal of pectin during PMP production impacts PMP uptake, Alfalfa sprouts were obtained from a local supermarket, were treated with pectinase-treated and untreated DyLight800-Lemon PMPs, water (negative control), DyLight800 nm dye only (dye aggregate control) in half-strength Murashige and Skoog (MS), supplemented with 0.5% sucrose and 2.5 mM MES, pH 5.6 for 21 hours at 23° C. (FIG. 9A). Seedlings where then washed 3 times in MS medium, and imaged using an Odyssey infrared imager. There was no difference in uptake and transport of PMPs produced with or without pectinase treatment (FIG. 9B).

Example 6: PMP Production from Blended Fruit Juice Using Ultracentrifugation and Sucrose Gradient Purification

In this example, PMPs were produced from fruit by blending the fruit and using a combination of sequential centrifugation to remove debris, ultracentrifugation to pellet crude PMPs, and using a sucrose density gradient to purify PMPs. Grapefruit was used as a model fruit.

a) Production of Grapefruit PMPs by Ultracentrifugation and Sucrose Density Gradient Purification

An exemplary workflow for grapefruit PMP production using a blender, ultracentrifugation and sucrose gradient purification is shown in FIG. 10A. One red grapefruit was purchased from a local market, and the albedo, flavedo, and segment membranes were removed to collect juice sacs, which were homogenized using a blender at maximum speed for 10 minutes. One hundred mL juice was diluted 5× with PBS, followed by subsequent centrifugation at 1000×g for 10 minutes, 3000× g for 20 minutes, and 10,000× g for 40 minutes to remove large debris. 28 mL of cleared juice was ultracentrifuged on a Sorvall™ MX 120 Plus Micro-Ultracentrifuge at 150,000× g for 90 minutes at 4° C. using a S50-ST (4×7 mL) swing bucket rotor to obtain a crude PMP pellet which was resuspended in PBS pH 7.4. Next, a sucrose gradient was prepared in Tris-HCL pH7.2, crude PMPs were layered on top of the sucrose gradient (from top to bottom: 8, 15, 30, 45 and 60% sucrose), and spun down by ultracentrifugation at 150,000×g for 120 minutes at 4° C. using a S50-ST (4×7 mL) swing bucket rotor. One mL fractions were collected and PMPs were isolated at the 30-45% interface. The fractions were washed with PBS by ultracentrifugation at 150,000×g for 120 minutes at 4° C. and pellets were dissolved in a minimal amount of PBS.

PMP concentration (1×10⁹ PMPs/mL) and median PMP size (121.8 nm) were determined using a Spectradyne nCS1™ particle analyzer, using a TS-400 cartridge (FIG. 10B). The zeta potential was determined using a Malvern Zetasizer Ultra and was −11.5+/−0.357 mV.

In this example, grapefruit PMPs were isolated using ultracentrifugation combined with sucrose gradient purification methods. However, this method induced gelling of the samples at all PMP production steps and in the final PMP solution.

Example 7: PMP Production from Mesh-Pressed Fruit Juice Using Ultracentrifugation and Sucrose Gradient Purification

In this example, cell wall and cell membrane contaminants were reduced during the PMP production process using a milder juicing process (mesh strainer). Grapefruit was used as a model fruit. a) Mild juicing reduces gelling during PMP production from grapefruit PMPs Juice sacs were isolated from a red grapefruit as described in Example 2. To reduce gelling during PMP production, instead of using a destructive blending method, juice sacs were gently pressed against a tea strainer mesh to collect the juice and to reduce cell wall and cell membrane contaminants. After differential centrifugation, the juice was clearer than after using a blender, and one clean PMP-containing sucrose band at the 30-45% intersection was observed after sucrose density gradient centrifugation (FIG. 11). There was overall less gelling during and after PMP production.

Our data shows that use of a mild juicing step reduces gelling caused by contaminants during PMP production when compared to a method comprising blending.

Example 8: PMP Production Using Ultracentrifugation and Size Exclusion Chromatography

This example describes the production of PMPs from fruits by using Ultracentrifugation (UC) and Size Exclusion Chromatography (SEC). In this example, grapefruit is used as a model fruit.

a) Production of Grapefruit PMPs Using UC and SEC

Juice sacs were isolated from a red grapefruit, as described in Example 6a, and were gently pressed against a tea strainer mesh to collect 28 ml juice. The workflow for grapefruit PMP production using UC and SEC is depicted in FIG. 12A. Briefly, juice was subjected to differential centrifugation at 1000×g for 10 minutes, 3000× g for 20 minutes, and 10,000× g for 40 minutes to remove large debris. 28 ml of cleared juice was ultracentrifuged on a Sorvall™ MX 120 Plus Micro-Ultracentrifuge at 100,000× g for 60 minutes at 4° C. using a S50-ST (4×7 mL) swing bucket rotor to obtain a crude PMP pellet which was resuspended in MES buffer (20 mM MES, NaCl, pH 6). After washing the pellets twice with MES buffer, the final pellet was resuspended in 1 ml PBS, pH 7.4. Next, we used size exclusion chromatography to elute the PMP-containing fractions. SEC elution fractions were analyzed by nano-flow cytometry using a NanoFCM to determine PMP size and concentration using concentration and size standards provided by the manufacturer. In addition, absorbance at 280 nm (SpectraMax®) and protein concentration (Pierce™ BCA assay, ThermoFisher) were determined on SEC fractions to identify in which fractions PMPs are eluted (FIGS. 12B-12D). SEC fractions 2-4 were identified as the PMP-containing fractions. Analysis of earlier- and later-eluting fractions indicated that SEC fraction 3 is the main PMP-containing fraction, with a concentration of 2.83×10¹¹ PMPs/mL (57.2% of all particles in the 50-120 nm size range), with a median size of 83.6 nm+/−14.2 nm (SD). While the late elution fractions 8-13 had a very low concentration of particles as shown by NanoFCM, protein contaminants were detected in these fractions by BCA analysis.

Our data shows that TFF and SEC can be used to isolate purified PMPs from late-eluting contaminants, and that a combination of the analysis methods used here can identify PMP fractions from late-eluting contaminants.

Example 9: Scaled PMP Production Using Tangential Flow Filtration and Size Exclusion Chromatography Combined with EDTA/Dialysis to Reduce Contaminants

This example describes the scaled production of PMPs from fruits by using Tangential Flow Filtration (TFF) and Size Exclusion Chromatography (SEC), combined with an EDTA incubation to reduce the formation of pectin macromolecules, and overnight dialysis to reduce contaminants. In this example, grapefruit is used as a model fruit.

a) Production of Grapefruit PMPs Using TFF and SEC

Red grapefruits were obtained from a local market, and 1000 ml juice was isolated using a juice press. The workflow for grapefruit PMP production using TFF and SEC is depicted in FIG. 13A. Juice was subjected to differential centrifugation at 1000×g for 10 minutes, 3000× g for 20 minutes, and 10,000× g for 40 minutes to remove large debris. Cleared grapefruit juice was concentrated and washed once using a TFF (TFF-easy, HansaBioMed Life Sciences) to 2 mL (100×). Next, we used size exclusion chromatography to elute the PMP-containing fractions. SEC elution fractions were analyzed by nano-flow cytometry using a NanoFCM to determine PMP concentration using concentration and size standards provided by the manufacturer. In addition, protein concentration (Pierce™ BCA assay, ThermoFisher) was determined for SEC fractions to identify the fractions in which PMPs are eluted. The scaled production from 1 liter of juice (100× concentrated) also concentrated a high amount of contaminants in the late SEC fractions as can be detected by BCA assay (FIG. 13B, top panel). The overall total PMP yield (FIG. 13B, bottom panel) was lower in the scaled production when compared to single grapefruit isolations, which may indicate loss of PMPs.

b) Reducing Contaminants by EDTA Incubation and Dialysis

Red grapefruits were obtained from a local market, and 800 ml juice was isolated using a juice press. Juice was subjected to differential centrifugation at 1000×g for 10 minutes, 3000× g for 20 minutes, and 10,000× g for 40 minutes to remove large debris, and filtered through a 1 μm and 0.45 μm filter to remove large particles. Cleared grapefruit juice was split into 4 different treatment groups containing 125 ml juice each. Treatment Group 1 was processed as described in Example 9a, concentrated and washed (PBS) to a final concentration of 63×, and subjected to SEC. Prior to TFF, 475 ml juice was incubated with a final concentration of 50 mM EDTA, pH 7.15 for 1.5 hrs at RT to chelate iron and reduce the formation of pectin macromolecules. Afterwards, juice was split in three treatment groups that underwent TFF concentration with either a PBS (without calcium/magnesium) pH 7.4, MES pH 6, or Tris pH 8.6 wash to a final juice concentration of 63×. Next, samples were dialyzed in the same wash buffer overnight at 4° C. using a 300 kDa membrane and subjected to SEC. Compared to the high contaminant peak in the late elution fractions of the TFF only control, EDTA incubation followed by overnight dialysis strongly reduced contaminants, as shown by absorbance at 280 nm (FIG. 13C) and BCA protein analysis (FIG. 13D), which is sensitive to the presence of sugars and pectins. There was no difference in the dialysis buffers used (PBS without calcium/magnesium pH 7.4, MES pH 6, Tris pH 8.6).

Our data indicates that incubation with EDTA followed by dialysis reduces the amount of co-purified contaminants, facilitating scaled PMP production.

Example 10: PMP Production from Plant Cell Culture Medium

In this example, PMPs were produced from plant cell culture. The Zea mays Black Mexican Sweet (BMS) cell line is used as a model plant cell line.

a) Production of Zea mays BMS Cell Line PMPs

The Zea mays Black Mexican sweet (BMS) cell line was purchased from the ABRC and was grown in Murashige and Skoog basal medium pH 5.8, containing 4.3 g/L Murashige and Skoog Basal Salt Mixture (Sigma M5524), 2% sucrose (S0389, Millipore Sigma), 1× MS vitamin solution (M3900, Millipore Sigma), 2 mg/L 2,4-dichlorophenoxyacetic acid (D7299, Millipore Sigma) and 250 ug/L thiamine HCL (V-014, Millipore Sigma), at 24° C. with agitation (110 rpm), and was passaged 20% volume/volume every 7 days.

Three days after passaging, 160 ml BMS cells was collected and spun down at 500× g for 5 min to remove cells, and 10,000×g for 40 min to remove large debris. Medium was passed through a 0.45 μm filter to remove large particles, and filtered medium was concentrated and washed (100 ml MES buffer, 20 mM MES, 100 mM NaCL, pH 6) by TFF (5 nm pore size) to 4 mL (40×). Next, we used size exclusion chromatography to elute the PMP-containing fractions, which were analyzed by NanoFCM for PMP concentration, by absorbance at 280 nm (SpectraMax®), and by a protein concentration assay (Pierce™ BCA assay, ThermoFisher) to verify the PMP-containing fractions and late fractions containing contaminants (FIGS. 14A-14C). SEC fractions 4-6 contained purified PMPs (fractions 9-13 contained contaminants), and were pooled together. The final PMP concentration (2.84×10¹⁰ PMPs/ml) and median PMP size (63.2 nm+/−12.3 nm SD) in the combined PMP containing fractions were determined by NanoFCM, using concentration and size standards provided by the manufacturer (FIGS. 14D-14E).

These data show that PMPs were isolated, purified, and concentrated from plant liquid culture media.

Example 11: Uptake of PMPs by Plant Cells

This example describes the association with and uptake of PMPs by plant cells. In this example, lemon PMPs are used as a model PMP, and soy, wheat and corn cell lines are used as model plant cells.

a) Production of Grapefruit PMPs Using TFF Combined with SEC

Red organic grapefruits (Florida) were obtained from a local market. One liter of grapefruit juice was collected using a juice press, and was subsequently centrifuged at 3000×g for 20 minutes, followed by 10,000× g for 40 minutes to remove large debris. Next, 500 mM EDTA pH 8.6 was added to a final concentration of 50 mM EDTA, pH 7, and the solution was incubated for 30 minutes to chelate calcium and prevent the formation of pectin macromolecules. Subsequently the juice was passaged through 11 μm, 1 μm and 0.45 μm filters to remove large particles. Filtered juice was concentrated and washed (500 ml PBS) by Tangential Flow Filtration (TFF) (pore size 5 nm) to 400 ml (2.5×) and dialyzed overnight in PBS pH 7.4 (with one medium exchange) using a 300 kDa dialysis membrane to remove contaminants. Subsequently, the dialyzed juice was further concentrated by TFF to a final concentration of 50 ml (20×). Next, we used size exclusion chromatography to elute the PMP-containing fractions, which were analyzed by absorbance at 280 nm (SpectraMax®) and a protein concentration assay (Pierce™ BCA assay, ThermoFisher) to verify the PMP-containing fractions and late fractions containing contaminants. SEC fractions 4-6 contained purified PMPs (fractions 8-14 contained contaminants), were pooled together, and were filter sterilized by sequential filtration using 0.8 m, 0.45 m and 0.22 m syringe filters. The final PMP concentration (1.32×10¹¹ PMPs/mL) and median PMP size (71.9 nm+/−14.5 nm) in the combined sterilized PMP-containing fractions were determined by NanoFCM using concentration and size standards provided by the manufacturer.

b) Production of Lemon PMPs Using TFF Combined with SEC

Lemons were obtained from a local market. One liter of lemon juice was collected using a juice press, and was subsequently centrifuged at 3000 g for 20 minutes, followed by 10,000 g for 40 minutes to remove large debris. Next, 500 mM EDTA pH 8.6 was added to a final concentration of 50 mM EDTA, pH 7, and the solution was incubated for 30 minutes to chelate calcium and prevent the formation of pectin macromolecules. Subsequently the juice was passaged through a coffee filter, 1 μm and 0.45 μm filters to remove large particles. Filtered juice was concentrated by Tangential Flow Filtration (TFF) (5 nm pore size) to 400 ml (2.5× concentrated) and dialyzed overnight in PBS pH 7.4 using a 300 kDa dialysis membrane to remove contaminants. Subsequently, the dialyzed juice was further concentrated by TFF to a final concentration of 50 ml (20×). Next, we used size exclusion chromatography to elute the PMP-containing fractions, which were analyzed by absorbance at 280 nm (SpectraMax®) and a protein concentration assay (Pierce™ BCA assay, ThermoFisher) to verify the PMP-containing fractions and late fractions containing contaminants. SEC fractions 4-6 contained purified PMPs (fractions 8-14 contained contaminants), were pooled together, and were filter sterilized by sequential filtration using 0.8 m, 0.45 m and 0.22 m syringe filters. The final PMP concentration (2.7×10¹¹ PMPs/mL) and median PMP size (70.7 nm+/−15.8 nm) in the combined sterilized PMP-containing fractions were determined by NanoFCM, using concentration and size standards provided by the manufacturer.

c) Labeling of Lemon PMPs with Alexa Fluor 488 NHS Ester

Lemon PMPs were produced as described in Example 11b. PMPs were labeled with the Alexa Fluor 488® NHS Ester (Life Technologies, covalent membrane dye (AF488)). Briefly, AF488 was dissolved in DMSO to a final concentration of 10 mg/ml, 200 ul of PMPs (1.53E+13 PMPs/ml) were mixed with 5 ul dye, incubated for 1 h at room temperature on a shaker, and labeled PMPs were washed 2-3 times by ultracentrifuge at 100,000×g for 1 hr at 4° C. Pellets were resuspended with 1.5 ml UltraPure water. To control for the presence of potential dye aggregates, a dye-only control sample was prepared according to the same procedure, adding 200 ul of UltraPure water instead of PMPs. The final AF488-labeled PMP pellet and AF488 dye-only control were resuspended in a minimal amount of UltraPure water and characterized by NanoFCM. The final concentration of lemon 488-labeled PMPs was 2.91×10¹² PMPs/ml with a median AF488-PMP size of 79.4 nm+/−14.7 nm and a labeling efficiency of 89.4% (FIG. 15A).

d) Uptake of AF488-Labeled Lemon PMPs by Plant Cells

Plant cell lines were purchased from the Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSMZ) (Glycine max, #PC-1026; Triticum aestivum, #PC-998) and ABRC (Zea mays, Black Mexican sweet (BMS), and were grown in baffled vented 250 mL flasks in the dark, at 24° C. with agitation (110 rpm). Glycine max and Triticum aestivum were grown in 3.2 g/L Gamborg's B-5 Basal Medium with Minimal Organics supplemented (G5893, Millipore Sigma) pH 5.5, supplemented with 2% sucrose, and 2 mg/L 2,4-dichlorophenoxyacetic acid (2,4D) (D7299, Millipore Sigma) according to the supplier's instructions. BMS cells were grown in Murashige and Skoog basal medium pH 5.8, containing 4.3 g/L Murashige and Skoog Basal Salt Mixture (Sigma M5524), 2% sucrose (S0389, Millipore Sigma), 1× MS vitamin solution (M3900, Millipore Sigma), 2 mg/L 2,4-dichlorophenoxyacetic acid (D7299, Millipore Sigma) and 250 ug/L thiamine HCL (V-014, Millipore Sigma).

For treatment with AF488-PMPs, 5 mL of the cell suspensions was taken to determine the percent Pack Cell Volume (PCV). The PCV is defined as the volume of cells divided by the total volume of the cell culture aliquot, and expressed as a percentage. Cells were centrifuged for 5 min at 3900 rpm, and the volume of the cell pellet was determined. The % PCV for BMS, Glycine max, and Triticum aestivum were 20%, 15%, and 18%, respectively. For the uptake experiment, the % PCV of the cultures was adjusted to 2%, by diluting cells in their appropriate medium. Next, 125 μl of the plant cell suspensions was added to a 24 well plate, and duplicate samples were treated with 125 μl MES buffer (200 mM MES+10 mM NaCl, pH6) alone (negative control), AF488 dye only (dye only control) or a final concentration of 1×10¹² AF488-PMPs/mL diluted in MES buffer to 125 μl. Cells were incubated for 2 hours at 24° C. in the dark, washed three times with 1 mL MES buffer to remove AF488-PMPs or free dye that had not been taken up, and resuspended in 300 μL of MES buffer for imaging on an epifluorescence microscope (EVOS FL Auto 2, Invitrogen). Compared to the AF488 dye only control which had no detectable fluorescence, a variable fluorescent signal could be detected in all plant cell lines, indicating PMP uptake (FIG. 15B). Triticum aestivum cells displayed the strongest fluorescence signal, indicating that out of the three plant cell lines tested, they had the highest uptake of AF488-labeled lemon PMPs.

Our data shows that PMPs can be taken up by plant cells in vitro.

Example 12: Uptake of PMPs in Plants

In this example, PMPs were taken up and systemically transported in planta. Grapefruit, lemon and Arabidopsis thaliana seedling PMPs are used as model PMPs, and Arabidopsis seedlings and alfalfa sprouts are used as model plants.

a) Labeling of Lemon and Grapefruit PMPs with DyLight 800 NHS Ester

Grapefruit and lemon PMPs were produced as described in Examples 11a and 11b. PMPs were labeled with the DyLight 800 NHS Ester (Life Technologies, #46421) covalent membrane dye (DyL800). Briefly, Dyl800 was dissolved in DMSO to a final concentration of 10 mg/ml, 200 μl of PMPs were mixed with 5 μl dye, incubated for 1 h at room temperature on a shaker, and labeled PMPs were washed 2-3 times by ultracentrifugation at 100,000×g for 1 hr at 4° C. and pellets were resuspended with 1.5 ml UltraPure water. To control for the presence of potential dye aggregates, a dye-only control sample was prepared according to the same procedure, adding 200 μl of UltraPure water instead of PMPs. The final DyL800-labeled PMP pellet and DyL800 dye-only control were resuspended in a minimal amount of UltraPure water and characterized by NanoFCM. The final concentration of grapefruit DyL800-labeled PMPs was 4.44×10¹² PMPs/ml, and of lemon DyL800-labeled PMPs was 5.18×10¹² PMPs/ml. The labeling efficiency could not be determined using the NanoFCM, as it cannot detect infrared.

b) Germination and Growth of Arabidopsis thaliana Seedlings

Wild type Arabidopsis thaliana Col-0 seeds were obtained from the ABRC and were surface sterilized with 70% ethanol, incubation with 50% bleach/0.1% triton X-100 for 10 minutes, and 4 sterile ddH₂O washes to remove the bleach solution. Seeds were stratified for 1 d at 4° C. in the dark. Approximately 250 seeds were germinated per 100 cm² plate (pre-coated with 0.5% fetal calf serum in water), containing 20 mL 0.5× MS medium (2.15 g/L Murashige and Skoog salts, 1% sucrose, pH 5.8), sealed with 3M surgical tape and grown in an incubator with a photoperiod of 16 h light at 23° C./8 h dark at 21° C.

c) Uptake of DyL800-Labeled Grapefruit, Lemon and Ats PMPs by Arabidopsis thaliana and Alfalfa

To assess whether PMPs can be taken up and transported systemically in planta, Arabidopsis seedlings were germinated in liquid culture as described in Example 12b on top of a mesh filter, to allow the roots to grow through the mesh, and to allow partial exposure of At seedlings to a PMP solution. Alfalfa sprouts were obtained from a local supermarket. 9 day-old Arabidopsis seedlings and Alfalfa sprouts were treated with a 0.5 ml solution of water (negative control), DyL800 dye only (dye control) DyL800-labeled grapefruit PMPs (1.6×10¹⁰ PMPs/ml), or lemon (5.1×10¹⁰ PMPs/ml) PMPs in 0.5×MS medium by partial root exposure (At seedlings in a mesh floating in a PMP solution, or in Alfalfa sprouts by partial root exposure in a 1.5 ml Eppendorf tube) for 22 or 24 hours, respectively, at 23° C. Plants where then washed 3 times in MS medium and imaged using an Odyssey® CLx infrared imager (Li-Cor).

Compared to the negative (some autofluorescence in Alfalfa sprout leafs) and dye only control, all PMP sources showed a fluorescence signal (white is high fluorescent signal, black is no signal) in both Arabidopsis seedlings and Alfalfa sprouts, indicating that PMPs are taken up by both plants (FIG. 16). The presence of fluorescence signal in Arabidopsis leafs or Alfalfa stem areas that were not exposed to the PMP solution indicates active transport of the PMPs in planta.

Our data indicate that PMPs derived from various plant sources can be taken up and transported in planta.

Example 13. PMP Preparations Resulting in Gelling

a) Production of PMPs Using a Blender

PMPs were produced from grapefruits using an exemplary workflow including blending, ultracentrifugation, and sucrose gradient purification, as shown in FIG. 1A. Briefly, grapefruit PMPs were produced by blending fruit in a blender at maximum speed for 10 minutes, followed by subsequent centrifugation at 1000×g for 10 minutes, 3000× g for 20 minutes, and 10,000×g for 40 minutes to remove large debris. Crude PMPs were pelleted by ultracentrifugation at 150,000×g for 90 minutes at 4° C. using a swing bucket rotor. PMPs were purified by sucrose density gradient using ultracentrifugation at 150,000×g for 120 minutes at 4° C. PMPs were isolated at the 30-35% interface, and the fraction was washed with PBS by ultracentrifugation. This production process resulted in gelling of the product at all steps of the production process.

b) Production of PMPs Using a Mesh Strainer Juicing Method

PMPs were produced from grapefruits using an exemplary workflow including a milder juice extraction method using a mesh strainer, ultracentrifugation, and sucrose gradient purification, as shown in FIG. 1B. Briefly, grapefruit PMPs were produced by isolating grapefruit juice sacs and gently pressing them through a tea strainer. The juice was collected and subsequently centrifuged at 1000×g for 10 minutes, 3000× g for 20 minutes, and 10,000×g for 40 minutes to remove large debris. Crude PMPs were pelleted by ultracentrifugation at 150,000×g for 90 minutes at 4° C. using a swing bucket rotor. PMPs were purified by sucrose density gradient using ultracentrifugation at 150,000×g for 120 minutes at 4 C. PMPs were isolated at the 30-35% interface, and the fraction was washed with PBS by ultracentrifugation. Compared to the sucrose gradient purification process in FIG. 1A, the gentle juicing process resulted in a whiter and cleaner PMP-containing sucrose band. However, this production process also resulted in gelling at all steps of the production process.

c) Production of PMPs Using a Juice Press

PMPs were produced from grapefruits using an exemplary workflow including a juice press, differential centrifugation to remove large debris, 20× concentration of the juice using tangential flow filtration (TFF), and size exclusion chromatography to isolate the PMP containing fractions, as shown in FIG. 1C. The PMP fractions were analyzed for PMP concentration and particle size using nano flow cytometry (NanoFCM) and for protein concentration using a bicinchoninic acid assay (BCA). PMP concentration in particles/mL is shown in FIG. 1D. PMPs are eluted in SEC fractions 4-6. The majority of PMPs are in SEC fraction 3 (Fr 3), as shown in FIG. 1E and Table 11. PMP production using a juice press resulted in less gelling compared to the methods described in Examples 13a and 13b.

Example 14. Scaled PMP Preparations

a) Production of PMPs from a Large Volume of Grapefruit Juice

PMPs were produced from a large volume of grapefruit juice (1 liter, the juice of about 7 grapefruits) using an exemplary workflow including a juice press, differential centrifugation to remove large debris, 100× concentration of the juice using tangential flow filtration (TFF), and size exclusion chromatography to isolate the PMP-containing fractions, as shown in FIG. 2A. The PMP fractions were analyzed for PMP concentration and particle size using nano flow cytometry (NanoFCM) and for protein concentration using a bicinchoninic acid assay (BCA). In comparison to the PMP product from 150 mL of grapefruit juice (1 grapefruit), the PMP product from 1 L of grapefruit juice had a high amount of contaminants concentrated in the late SEC fractions, as detected using a BCA assay (FIG. 2B). Additionally, the overall PMP yield in particles/mL is lower than expected in the 1000 mL preparation, which may indicate loss of PMPs during the production process (FIG. 2B) as a result of pectin aggregation and gelling.

Example 15. Production of PMPs with Enhanced Removal of Contaminants

a) PMP Production Process Comprising Chelation and Dialysis

The PMP production process was modified to enhance the removal of contaminants. An exemplary workflow is provided in FIG. 3A. In short, a crude PMP preparation was produced from pressed juice, followed by subsequent centrifugation at 3000×g for 20 minutes, followed by centrifugation at 10,000×g for 40 minutes to remove large debris. To purify PMPs, the crude PMP preparation was incubated with 500 mM EDTA (pH 8.6) to a final concentration of 50 mM EDTA (pH 7.2-8) for 30 minutes to chelate calcium and prevent the formation of pectin macromolecules. Subsequently, the EDTA-treated crude PMP fraction was passaged through a 1 μm and a 0.45 μm filter. Filtered juice was washed with PBS and concentrated 5× by Tangential Flow Filtration (TFF). Concentrated juice was dialyzed in PBS overnight at 4° C. using a 300 kDa dialysis membrane to remove contaminants. Subsequently, the dialyzed juice was further concentrated by TFF to a final concentration of 20×. Next, size exclusion chromatography was used to elute the PMP-containing fractions. Combined PMP-containing fractions were further characterized as described below.

Incubation of the crude grapefruit PMP fraction with a final concentration of 50 mM EDTA (pH 7.2-8), followed by overnight dialysis using a 300 kDa membrane, successfully removed contaminants present in the late elution fractions after SEC, as shown by absorbance at 280 nm (FIG. 3B). The peak containing contaminants is indicated by an arrow. There was no difference in effectiveness among the dialysis buffers used (PBS without calcium/magnesium pH 7.4; MES pH 6; and Tris pH 8.6).

The PMP production process also successfully removed contaminants present in the late elution fractions after SEC as shown by BCA protein analysis, which is also sensitive to the presence of sugars and pectins (FIG. 3C). The peak containing contaminants is indicated by an arrow. There was no difference in effectiveness among the dialysis buffers used (PBS without calcium/magnesium pH 7.4; MES pH 6; and Tris pH 8.6).

b) PMP Production Process Comprising Chelation and Dialysis for Citrus Fruit or Plant Cell Culture

Citrus juice or plant cell culture medium is subjected to a PMP production process with enhanced removal of contaminants. An exemplary workflow is provided in FIGS. 4A and 4B. Briefly, juice or culture medium is collected and subsequently centrifuged at 1000×g for 10 minutes, 3000× g for 20 minutes, and 10,000×g for 40 minutes to remove large debris to produce the crude PMP fraction. The crude PMP fraction is incubated in a final concentration of 50 mM EDTA (pH 7) for 30 minutes, and subsequently passaged through a 1 μm and a 0.45 μm filter. Filtered juice or medium is concentrated 5× by Tangential Flow Filtration (TFF) with PBS washing, and dialyzed overnight in PBS using a 300 kDa dialysis membrane to remove contaminants. Subsequently, the dialyzed juice is further concentrated by TFF to a final concentration of 20×. Size exclusion chromatography is then used to elute the PMP-containing fractions, and the PMP-containing fractions are characterized by, e.g., analysis of PMP concentration and particle size using nano flow cytometry (NanoFCM) and of protein concentration using a bicinchoninic acid assay (BCA).

c) PMP Production Process Comprising Pectinase Treatment

A lemon juice preparation and a grapefruit juice preparation were subjected to a PMP production process including treatment with a pectinase.

Lemons were obtained from a local market. 1260 mL of lemon juice was collected using a juice press and was split into two fractions. 860 mL was untreated, and 835 mL was pH adjusted to pH 4 with NaOH and incubated with 6 U/mL pectinase (Sigma, 17389) for 1.45 hours at room temperature. Pectinase-treated and untreated juice was subsequently centrifuged at 3000 g for 20 minutes, followed by centrifugation at 10,000 g for 40 minutes to remove large debris. Turbidity was reduced in the pectinase-treated sample relative to the untreated sample (FIG. 5A).

Red organic grapefruits were obtained from a local market. 1695 mL of grapefruit juice was collected using a juice press and was split into two fractions. 860 mL was untreated, and 835 mL was pH adjusted to pH 4 with NaOH and incubated with 0.5 U/mL pectinase (Sigma, 17389) throughout subsequent processing steps. Pectinase-treated and untreated juice was subsequently centrifuged at 3000 g for 20 minutes, followed by centrifugation at 10,000 g for 40 minutes to remove large debris. Turbidity was reduced in the pectinase-treated sample relative to the untreated sample (FIG. 5B).

Turbidity of the grapefruit juice preparations was quantified as the volume of juice that could be processed per filter. The addition of pectinase during grapefruit PMP production reduced juice turbidity and facilitated sequential filtration of the differentially centrifuged juice prior to TFF, improving the production process. About four times more of the juice preparation can be processed per 1 um or 0.45 um filter when the juice preparation has been treated with a pectinase (FIG. 5C).

PMP concentration in the pectinase-treated grapefruit juice preparation was measured to be about 2.5 times lower than PMP concentration in the grapefruit juice preparation that was not treated with a pectinase (FIG. 6), which likely indicates the removal of pectinase particles with similar size properties as PMPs.

d) PMP Production Process Comprising Pectinase Treatment and Chelation

A grapefruit juice preparation was subjected to a PMP production process including treatment with a pectinase and chelation. An exemplary workflow is provided in FIG. 7A. Four liters of grapefruit juice were isolated using a juice press. The juice preparation was treated with 0.5 U/mL pectinase as described in Example 15c. The pectinase-treated juice preparation was then centrifuged at 1000×g for 10 minutes, 3000× g for 20 minutes, and 10,000×g for 40 minutes to remove large debris. The juice preparation was then treated with EDTA as described in Example 15a. The preparation was then concentrated 5× using a Spectrum® 300 kDa TFF filter module, washed by 6 volume exchanges with PBS, and concentrated to a final concentration of 20×. Next, size exclusion chromatography (maxiPURE-EVs columns, HansaBioMed Life Sciences) was used to elute the PMP-containing fractions.

For each of the nine columns (A-J), the PMP production process efficiently removed pectin, sugars, protein and other contaminants in the late SEC fractions, as measured by absorbance at 280 nm and by using a BCA protein concentration assay, while PMPs were detected in the early SEC fractions 3-7 (FIGS. 7B and 7C).

Example 16. Light Transmittance Spectra of Pectinase-Treated Juice

A light transmittance spectrum was collected for standard concentrations of pectin (0.1-1%), dissolved in ultrapure water. Increased pectin concentration reduced the % transmittance, i.e., increased the turbidity of the solution (FIG. 8A). The transmittance spectrum was measured on a SpectraMax® i3×.

The light transmittance spectra of a grapefruit juice preparation that was treated with a pectinase and a grapefruit juice preparation that was not treated with a pectinase were collected. In brief, a red grapefruit was juiced using a juice press and split into two fractions. One fraction was incubated with 1 U/mL pectinase (Sigma, 17389); as the pH of the juice was 3.5-4, the pH did not have to be adjusted for pectinase treatment. Pectinase-treated and untreated juice was subsequently centrifuged at 3000×g for 20 minutes, followed by centrifugation at 10,000×g for 40 minutes to remove large debris. Clarified supernatant was transferred to fresh tubes and brought to pH 7.5 with NaOH. The crude PMP juice fraction was subjected to transmittance spectrum analysis using a SpectraMax® i3×. Pectinase treatment increased the % transmittance, i.e., reduced the turbidity of the juice preparation (FIG. 8B).

Example 17. Delivery of a Pectinase-Treated PMP Preparation to a Plant

In this example, pectinase-treated PMPs were taken up and systemically transported in planta. Lemon PMPs are used as model PMPs, and alfalfa sprouts are used as model plants.

a) Labeling of Lemon PMPs with DyLight 800 NHS Ester

Pectinase-treated and untreated lemon PMPs were produced as described in Example 15c, using 0.5 U pectinase. PMPs were labeled with the DyLight 800 infrared membrane dye (Invitrogen; DyL800). Briefly, Dyl800 was dissolved in DMSO to a final concentration of 10 mg/ml, 200 μl of PMPs were mixed with 5 μl dye, incubated for 1 h at room temperature on a shaker, and labeled PMPs were washed 2-3 times by ultracentrifugation at 100,000×g for 1 hr at 4° C. and pellets were resuspended with 1.5 ml UltraPure water. To control for the presence of potential dye aggregates, a dye-only control sample was prepared according to the same procedure, adding 200 μl of UltraPure water instead of PMPs. The final DyL800-labeled PMP pellet and DyL800 dye-only control were resuspended in a minimal amount of UltraPure water and characterized by NanoFCM.

b) Uptake of DyL800-Labeled Lemon PMPs by Alfalfa Sprouts

To assess whether pectinase treatment affects uptake and/or systemic transport of PMPs, alfalfa sprouts were obtained from a local supermarket. Alfalfa sprouts were treated with a 0.5 mL solution of water (negative control), DyL800 dye only (dye control), pectinase-treated lemon PMPs, or untreated lemon PMPs in half-strength Murashige and Skoog (MS) medium supplemented with 0.5% sucrose and 2.5 mM MES, pH 5.6 by partial root exposure in a 1.5 ml Eppendorf tube for 21 hours at 23° C. Plants were then washed 3 times in MS medium and imaged using an Odyssey® CLx infrared imager (Li-Cor) (FIG. 9A). There was no difference in uptake and transport of PMPs produced with or without pectinase treatment, as can be observed by the similar infrared signal intensity and height of the signal in the stem of the treated alfalfa sprouts (FIG. 9B).

Example 18: PMP Production from 18 L of Citrus Fruit Juice

This example describes production of PMPs at 18 L scale. During the production process, citrus juice was treated with pectinase enzyme and incubated with EDTA to prevent pectin aggregation. In this example, grapefruit is used as a model fruit.

a) Production of Grapefruit PMPs from 18 Liters of Juice

Red grapefruits were obtained from a local grocery market. Fruits were washed with 1% Liquinox® detergent (Alconox®) and rinsed under warm water. Next, 18 L of juice was isolated using a commercial citrus juicer (Zumex®, Model No. 08826) and processed by progressive clarification. Large pulp fragments were removed by the juicer itself, and a subsequent filtration through a 600 μm nylon screen filter was performed. The juice was brought to pH 4 with 10N sodium hydroxide solution (VWR Chemicals BDH®), before the addition of pectinase enzyme at a final concentration of 0.5 U/mL (Pectinase from Aspergillus niger, TCI P0026-10). The enzymatic digestion of pectin was performed at room temperature (23° C.-25° C.) for at least 2 hours. Then, a series of differential centrifugations at 3000× g for 20 minutes and 10,000× g for 40 minutes was performed to remove large debris. Subsequent juice clarification was performed by vacuum filtration through 11 μm disk filters (Whatman®) set on a funnel-flask system. Further clarification was performed using a 1.2 μm glass fiber depth filter (Glass fiber, Sartopure® GF+1.2 μm, Sartorius) set on a peristaltic pump system (250 liter/m²/hour (LMH)), followed by a 0.8/0.45 μm PES depth filter (PES, Sartopore® 2, 0.8/0.45 um, 250 LMH). EDTA was added to the juice at a final concentration of 50 mM, and pH was brought to pH 7.5. The clarified juice was stored at 4° C. overnight and was then processed using a TFF system (Repligen, KrosFlo® KR2i TFF System) with a TFF mPES hollow fiber filter (mPES, 300 kDa pore size. Repligen), sequentially concentrated 12.5× (1.6 L), washed by diafiltration with 7 diavolumes of filter sterilized PBS pH7.4, and finally concentrated to 60× based on the initial juice volume (300 mL).

Next, we used size exclusion chromatography to elute the PMP-containing fractions (maxiPURE-EVs size exclusion chromatography columns, HansaBioMed Life Sciences). To identify the PMP-containing fractions, SEC elution fractions were analyzed by absorbance measurement at 280 nm (SpectraMax® spectrophotometer), protein quantification was performed by BCA assay (Pierce™ BCA Protein Assay Kit, Thermo Scientific™), and PMP concentration was determined by nano-flow cytometry (nanoFCM) using concentration standards provided by the manufacturer. SEC fractions 4-8, which contained PMPs, were then combined under aseptic conditions in a tissue culture hood and were syringe filter-sterilized through a 1 μm filter (Glass fiber, Acrodisc®, Pall Laboratory), 0.8/0.45 μm set-pore size filter (PES, Sartopore® 2, 0.8/0.45 μm PES) and finally a 0.2 μm set-pore size filter (Sartopore® 2, 0.2 μm PES). After sterilization, PMPs were concentrated in sterile tubes by ultracentrifugation at 40,000×g for 1.5 h at 4° C., and the resulting pellets were resuspended in sterile PBS pH 7.4 (GIBCO) to a final volume of 15 mL, which represents a 1200× concentration from the input juice volume. The PMP suspension was then analyzed by nanoFCM to determine the final PMP concentration (1.98×10¹³ PMPs/mL) and size (78.1 nm±19.6 nm) using concentration and size standards provided by the manufacturer, and protein concentration (8.39 mg/mL) was determined by BCA assay (Pierce™ BCA Protein Assay Kit, Thermo Scientific™).

Example 19: PMP Production from Homogenized Plant Sources

This example describes PMP production from homogenized plant sources, including large fruits, berries, whole plants, and vegetables. In this example, Wolffia globosa is used as a model plant, pomegranate and blueberries as model fruits, and broccoli as a model vegetable.

a) Production of Pomegranate PMPs

Pomegranates were obtained from a local grocery market. Fruits were washed with 1% detergent (Alconox®) and rinsed under warm water. Next, 8 L of juice was isolated using a juicer/mincer machine (Slowstar). Juice went through a progressive clarification process. The juice was brought to pH 4 with 10N sodium hydroxide solution (VWR Chemicals BDH®) before the addition of pectinase enzyme at a final concentration of 0.5 U/mL (Pectinase from Aspergillus niger, Sigma-Aldrich 17389). The enzymatic digestion of pectin was performed at room temperature for at least 2 hours (25° C.). Then, a series of differential centrifugations at 3000× g for 20 minutes and 10,000× g for 40 minutes was performed to remove large debris. Subsequent juice clarification was performed using Miracloth mesh (20-25 μm, Sigma-Aldrich) to remove additional debris. EDTA was added to the juice at a final concentration of 50 mM, and pH was brought to pH 7.5. Further clarification of the juice was performed by vacuum filtration through 11 μm disk filters (Whatman®) set on a funnel-flask system, followed by 1 μm glass fiber depth filter (Glass fiber, Acrodisc®, Pall Laboratory) set on a peristaltic pump system (250 LMH), followed by a 0.8/0.45 μm PES depth filter (PES, Sartopore® 2, 0.8/0.45 um, 250 LMH). The clarified juice was stored at 4° C. overnight. Next, the juice was processed using a TFF system (Repligen, KrosFlo® KR2i TFF System) with a TFF mPES hollow fiber filter (mPES, 300 kDa pore size) sequentially concentrated 10× (1.6 L), washed by diafiltration with 10 diavolumes of filter-sterilized PBS (pH 7.4), and finally concentrated to 70× based on the initial juice volume.

Next, we used size exclusion chromatography to elute the PMP-containing fractions (maxiPURE-EVs size exclusion chromatography columns, HansaBioMed Life Sciences). To identify the PMP-containing fractions, SEC elution fractions were analyzed by absorbance measurement at 280 nm (SpectraMax® spectrophotometer), protein quantification was performed by BCA assay, and PMP concentration was determined by nanoFCM using concentration standards provided by the manufacturer. SEC fractions 4-7, which contained PMPs, were then combined under aseptic conditions in a TC hood and were syringe filter-sterilized through a 1 μm filter (glass fiber 1 μm 37 mm, VWR), 0.45 um filter (PES, Whatman® PURADISC™) and finally through a 0.45/0.2 μm set pore-size filter (Sartopore® 2, 0.2 um PES). After sterilization, PMPs were concentrated by ultracentrifugation at 40,000×g for 1.5 hours at 4° C. The pellet was resuspended in sterile PBS pH7.4 (GIBCO) and final particle concentration (4.33×10¹³ PMPs/mL) and median size (79.3 nm±17.2 nm) were determined by NanoFCM. Protein concentration was determined using a BCA assay (15.8 mg/mL). PMP ultrastructural characterization was performed by cryo-electron microscopy.

b) Production of Blueberry PMPs

Blueberries (2.5 kg) were obtained from a local grocery market. Fruits were washed with 1% detergent (Alconox®) and rinsed under warm water. Next, the blueberry juice was isolated using a juicer/mincer machine (Slowstar). 2.6 L of PBS pH 7.4 buffer was added during the juicing process in order to retrieve the extracted material while reducing juice viscosity to a final volume of 5.2 L. The collected juice went through a progressive clarification process. First, the juice was brought to pH 4 with 10N sodium hydroxide solution (VWR Chemicals BDH®), before the addition of pectinase enzyme at a final concentration of 1 U/mL (Pectinase from Aspergillus niger, Sigma-Aldrich 17389). The enzymatic digestion of pectin was performed at room temperature (23° C.-25° C.) for at least 2 hours. Then, a series of differential centrifugations at 3000× g for 20 minutes and 10,000× g for 40 minutes was carried out to remove large debris. Subsequent juice clarification was performed using a Miracloth mesh (20-25 μm, Sigma-Aldrich) to remove additional debris. EDTA was added to the 4.5 L of juice at a final concentration of 50 mM, and pH was brought to pH 7.5. Further clarification of the juice was performed by vacuum-filtration through 11 μm disk filters (Whatman®) set on a funnel-flask system, followed by 1 μm filtration (Glass fiber, Acrodisc®, Pall Laboratory) set on a peristaltic pump system (250 LMH, liter/m²/hour) and a 0.45 μm filter (PES, CELLTREAT® Scientific Products) set on a vacuum system. The clarified juice was stored at 4° C. overnight. Next, the juice was processed using a TFF system (Repligen, KrosFlo® KR2i TFF System) with a TFF mPES hollow fiber filter (mPES, 300 kDa pore size), sequentially concentrated 10× (1.6 L), washed by diafiltration with 10 diavolumes of filter sterilized PBS pH7.4, and finally concentrated to 70× based on the initial juice volume.

Next, we used size exclusion chromatography to elute the PMP-containing fractions (maxiPURE-EVs size exclusion chromatography columns, HansaBioMed Life Sciences). To identify the PMP-containing fractions, SEC elution fractions were analyzed by absorbance measurement at 280 nm (SpectraMax® spectrophotometer), protein quantification was performed by BCA assay, and PMP concentration was determined by nanoFCM using concentration standards provided by the manufacturer. Based on nanoFCM particle counts, blueberry PMPs were eluted in early SEC fractions 6-8, and a high amount of contaminants are present in late SEC fractions (9-14). SEC fractions 6-8, which contained PMPs, were then combined under aseptic conditions in a TC hood and were syringe filter-sterilized through a 1 μm filter (Glass fiber, Acrodisc®, Pall Laboratory), and finally through a 0.45 μm filter (PES, Whatman® Puradisc). After sterilization, PMPs were concentrated by ultracentrifugation at 40,000×g for 1.5 h at 4° C. The pellet was resuspended in sterile PBS pH 7.4 (GIBCO), and final particle concentration (4.04×10¹¹ PMPs/mL) and median size (77.2 nm+/−17.9 nm) were determined by NanoFCM. Protein concentration was determined by BCA assay (2 μg/mL). PMP ultrastructural characterization was performed by cryo-electron microscopy.

c) Production of Wolffia globosa (Duckweed) PMPs

Wolffia globosa strain 9349-31 was obtained from Rutgers Duckweed Stock Cooperative and cultured in house in frond medium at pH 5.8 (3.2 g/L Schenk & Hildebrandt basal salt mixture, 20 g/L sucrose, pH 5.8 adjusted with KOH) at 25° C. under continuous light and 100 rpm agitation conditions (Percival incubator). Wolffia globosa whole plants were harvested at 5% (weight/volume) density from 400 mL of culture through filtration using a Miracloth mesh (20-25 um, Sigma-Aldrich). Next, approximately 18 g of plants were blended in a food processor (Oster, 2 minutes at maximum speed) with the addition of 135 mL of PBS pH 7.4. The blended plants were processed through a progressive clarification process. First, the blended plants were brought to pH 4 with 10N sodium hydroxide solution (VWR Chemicals BDH®), before the addition of pectinase enzyme at a final concentration of 0.5 U/mL (Pectinase from Aspergillus niger, Sigma-Aldrich 17389). The enzymatic digestion of pectin was performed at room temperature for at least 2 hours (25° C.). Then, a series of differential centrifugations at 3000× g for 20 minutes was carried out to remove large debris. Subsequent clarification was performed using Miracloth mesh (20-25 μm, Sigma-Aldrich) to remove additional debris. EDTA was added to the blended extract at a final concentration of 50 mM, and pH was brought to pH 7.5. Further clarification was done by vacuum-filtration through 11 μm disk filters (Whatman®) set on a funnel-flask system, followed by 1 μm syringe filtration (Glass fiber, Acrodisc®, Pall Laboratory) and a 0.45 μm filter (PES, CELLTREAT® Scientific Products) set on a vacuum system. The clarified blended-plant solution was stored at 4° C. overnight. Samples were then processed successively using a TFF system and size exclusion chromatography. The TFF system (Repligen, KrosFlo® KR2i TFF System) used was set with a TFF mPES hollow fiber filter (mPES, 300 kDa pore size). The samples were sequentially concentrated 12.5×, washed by diafiltration with 7 diavolumes of filter sterilized PBS pH 7.4, and finally concentrated to 50× based on the initial juice volume.

Next, we used size exclusion chromatography to elute the PMP-containing fractions (maxiPURE-EVs size exclusion chromatography columns, HansaBioMed Life Sciences). To identify the PMP-containing fractions, SEC elution fractions were analyzed by absorbance measurement at 280 nm (SpectraMax® spectrophotometer), protein quantification was performed by BCA assay, and PMP concentration was determined by nanoFCM using concentration standards provided by the manufacturer. SEC fractions 4-7, which contained PMPs, were then combined under aseptic conditions in a TC hood and were syringe filter-sterilized through a 1 μm filter (Glass fiber, Acrodisc®, Pall Laboratory), and finally through an 0.45 μm filter (PES, Whatman® Puradisc). After sterilization, PMPs were concentrated by ultracentrifugation at 40,000×g, for 1.5 h at 4° C. The pellet was resuspended in sterile PBS pH7.4 (GIBCO) and final particle concentration (8.79×10¹² PMPs/mL), and size (91.8 nm±23.4 nm) were determined by nanoFCM. Protein concentration was determined by BCA assay (2.99 mg/mL).

d) Production of Broccoli PMPs

Broccoli crowns were obtained from a local grocery market. Broccoli crowns were hand-washed with 1% detergent (Alconox®) and rinsed under warm water. Next, approximately 1.3 kg of broccoli was isolated using a juicer/mincer machine (Slowstar) with the addition of PBS pH 7.4. The resulting juice (800 mL) was processed through a 1 mm mesh metal strainer and Miracloth mesh (20-25 μm) to remove large debris. The broccoli juice was next processed through a progressive clarification process. First, the juice was brought to pH 4 with 10N sodium hydroxide solution (VWR Chemicals BDH®), before the addition of pectinase enzyme at a final concentration of 0.5 U/mL (Pectinase from Aspergillus niger, Sigma-Aldrich 17389). The enzymatic digestion of pectin was performed at room temperature for at least 2 hours (25° C.). Then, a series of differential centrifugations at 3000× g for 20 minutes and 10,000× g for 40 minutes to remove large debris were carried out. EDTA was added to the juice at a final concentration of 50 mM, and pH was brought to pH 7.5.

Further clarification of the juice was performed by vacuum filtration through 11 μm disk filters (Whatman®) set on a funnel-flask system, followed by 1 μm glass fiber syringe filtration (Glass fiber, Acrodisc®, Pall Laboratory) and 0.45 μm filtration (PES, CELLTREAT® Scientific Products). Next, the juice was processed using a TFF system (Repligen, KrosFlo® KR2i TFF System) with a TFF mPES hollow fiber filter (mPES, 300 kDa pore size) sequentially concentrated 10× (1.6 L), washed by diafiltration with 10 diavolumes of filter sterilized PBS (pH 7.4), and finally concentrated to 50× based on the initial juice volume.

Next, we used size exclusion chromatography to elute the PMP-containing fractions (maxiPURE-EVs, HansaBioMed Life Sciences). To identify the PMP-containing fractions, SEC elution fractions were analyzed by absorbance measurement at 280 nm (SpectraMax® spectrophotometer), protein quantification was performed by BCA assay, and PMP concentration was determined by nanoFCM using concentration standards provided by the manufacturer. SEC fractions 3-7, which contained PMPs, were then combined under aseptic conditions in a TC hood and were syringe filter-sterilized through a 1 μm filter (Glass fiber, Acrodisc®, Pall Laboratory), 0.45 μm filter (PES, Whatman® Puradisc) and finally through a 0.2 μm filter (PES, Whatman® Puradisc). After sterilization, PMPs were concentrated by ultracentrifugation at 40,000×g, for 1.5 h at 4° C. The resulting pellet was resuspended in sterile PBS pH7.4 (GIBCO), and final particle concentration (1.69×10¹² PMPs/mL), and size (80.3 nm±20.9 nm) were determined by NanoFCM. Protein concentration was determined by BCA assay (1.25 mg/mL). PMP ultrastructural characterization was performed by cryo-electron microscopy.
