Process for altering the host range or increasing the toxicity of Bacillus thuringiensis lepidoteran toxins, and recombinant DNA sequences therefor

Abstract

The invention concerns an in vitro process for altering the insect host range (spectrum) or increasing the toxicity of lepidopteran active B.t. crystal protein toxins. The process comprises recombining in vitro the variable region(s) (non-homologous) of two or more genes encoding lepidopteran active B.t. crystal protein toxins. Specifically exemplified is the recombining of the variable regions of two genes obtained from well-known strains of Bacillus thuringiensis var. kurstaki. The resulting products are chimeric toxins which are shown to have an expanded and/or amplified lepidopteran insect host range as compared to the parent toxins.

Description

BACKGROUND OF THE INVENTION

The most widely used microbial pesticides are derived from the bacterium Bacillus thuringiensis. This bacterial agent is used to control a wide range of leaf-eating caterpillars, Japanese beetles and mosquitos. Bacillus thuringiensis produces a proteinaceous paraspore or crystal which is toxic upon ingestion by a susceptible insect host. For example, B. thuringiensis var. kurstaki HD-1 produces a crystal called a delta toxin which is toxic to the larvae of a number of lepidopteran insects. The cloning and expression of this B.t. crystal protein gene in Escherichia coli has been described in the published literature (Schnepf, H. E. and Whiteley, H. R. [1981] Proc. Natl. Acad. Sci. USA 78:2893-2897). U.S. Pat. No. 4,448,885 and U.S. Pat. No. 4,467,036 both disclose the expression of B.t. crystal protein in E. coli. In U.S. Pat. No. 4,467,036 B. thuringiensis var. kurstaki HD-1 is disclosed as being available from the well-known NRRL culture repository at Peoria, Ill. Its accession number there is NRRL B-3792. B. thuringiensis var. kurstaki HD-73 is also available from NRRL. Its accession number is NRRL B-4488.

SUMMARY OF THE INVENTION

The subject invention concerns a novel process for altering the insect host range of Bacillus thuringiensis toxins, and novel toxins produced as exemplification of this useful process. This alteration can result in expansion of the insect host range of the toxin, and/or, amplification of host toxicity. The process comprises recombining in vitro the variable region(s) of two or more .delta.-endotoxin genes. Specifically exemplified is the recombining of portions of two Bacillus thuringiensis var. kurstaki DNA sequences, i.e., referred to herein as k-1 and k-73, to produce chimeric B.t. toxins with expanded host ranges as compared to the toxins produced by the parent DNA's.

"Variable regions," used herein, refers to the non-homologous regions of two or more DNA sequences. As shown by the examples presented herein, the recombining of such variable regions from two different B.t. DNA sequences yields, unexpectedly, a DNA sequence encoding a .delta.-endotoxin with an expanded insect host range. In a related example, the recombining of two variable regions of two different B.t. toxin genes results in the creation of a chimeric toxin molecule with increased toxicity toward the target insect. The utility of this discovery by the inventors is clearly broader than the examples disclosed herein. From this discovery, it can be expected that a large number of new and useful toxins will be produced. Thus, though the subject process is exemplified by construction of chimeric toxin-producing DNA sequences from two well-known B.t. kurstaki DNA sequences, it should be understood that the process is not limited to these starting DNA sequences. The invention process also can be used to construct chimeric toxins from any B. thuringiensis toxin-producing DNA sequence.

DETAILED DESCRIPTION OF THE INVENTION

Upon recombining in vitro the variable region(s) of two or more .delta.-endotoxin genes, there is obtained a gene(s) encoding a chimeric toxin(s) which has an expanded and/or amplified host toxicity as compared to the toxin produced by the starting genes. This recombination is done using standard well-known genetic engineering techniques.

The restriction enzymes disclosed herein can be purchased from Bethesda Research Laboratories, Gaithersburg, Md., or New England Biolabs, Beverly, Ma. The enzymes are used according to the instructions provided by the supplier.

The various methods employed in the preparation of the plasmids and transformation of host organisms are well known in the art. These procedures are all described in Maniatis, T., Fritsch, E. F., and Sambrook, J. (1982) Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, New York.

It should be understood that the availability of these deposits does not constitute a license to practice the subject invention in derogation of patent rights granted for the subject invention by governmental action.

As disclosed above, any B. thuringiensis toxin-producing DNA sequence can be used as starting material for the subject invention. Examples of B. thuringiensis organisms, other than those previously given, are as follows:

Though the main thrust of the subject invention is directed toward a process for altering the host range of B. thuringiensis toxins, the process is also applicable in the same sense to other Bacillus toxin-producing microbes. Examples of such Bacillus organisms which can be used as starting material are as follows:

Bacillus cereus--ATCC 21281 Bacillus moritai--ATCC 21282 Bacillus popilliae--ATCC 14706 Bacillus lentimorbus--ATCC 14707 Bacillus sphaericus--ATCC 33203

Bacillus thuringiensis M-7, exemplified herein, is a Bacillus thuringiensis isolate which, surprisingly, has activity against beetles of the order Coleoptera but not against Trichoplusia ni, Spodoptera exigua or Aedes aegypti. Included in the Coleoptera are various Diabrotica species (family Chrysomelidae) that are responsible for large agricultural losses, for example, D. undecimpuctata (western spotted cucumber beetle), D. longicornis (northern corn rootworm), D. virgitera (western corn rootworm), and D. undecimpunctata howardi (southern corn rootworm).

B. thuringiensis M-7 is unusual in having a unique parasporal body (crystal) which under phase contrast microscopy is dark in appearance with a flat, square configuration.

The pesticide encoded by the DNA sequence used as starting material for the invention process can be any toxin produced by a microbe. For example, it can be a polypeptide which has toxic activity toward a eukaryotic multicellular pest, such as insects, e.g., coleoptera, lepidoptera, diptera, hemiptera, dermaptera, and orthoptera; or arachnids; gastropods; or worms, such as nematodes and platyhelminths. Various susceptible insects include beetles, moths, flies, grasshoppers, lice, and earwigs.

Further, it can be a polypeptide produced in active form or a precursor or proform requiring further processing for toxin activity, e.g., the novel crystal toxin of B. thuringiensis var. kurstaki, which requires processing by the pest.

The constructs produced by the process of the invention, containing chimeric toxin-producing DNA sequences, can be transformed into suitable hosts by using standard procedures, Illustrative host cells may include either prokaryotes or eukaryotes, normally being limited to those cells which do not produce substances toxic to higher organisms, such as mammals. However, organisms which produce substances toxic to higher organisms could be used, where the toxin is unstable or the level of application sufficiently low as to avoid any possibility of toxicity to a mammalian host. As hosts, of particular interest will be the prokaryotes and lower eukaryotes, such as fungi. Illustrative prokaryotes, both Gram-negative and -positive, include Enerobacteriaceae, such as Escherichia, Erwinia, Shigella, Salmonella, and Proteus; Bacillaceae; Rhizobiaceae, such as Rhizobrium; Spirillaceae, such as photobacterium, Zymomonas, Serratia, Aeromonas, Vibrio, Desulfovibrio, Spirillum; Lactobacillaceae; Pseudomonadaceae, such as Pseudomonas and Acetobacter; Azotobacteraceae and Nitrobacteraceae. Among eukaryotes are fungi, such as Phycomycetes and Ascomycetes, which includes yeast, such as Saccharomyces and Schizosaccharomyces; and Basidiomycetes yeast, such as Rhodotorula, Aureobasidium, Sporobolomyces, and the like.

Characteristics of particular interest in selecting a host cell for purposes of production include ease of introducing the chimeric toxin-producing gene into the host, availability of expression systems, efficiency of expression, stability of the pesticide in the host, and the presence of auxiliary genetic capabilities. Characteristics of interest for use as a pesticide microcapsule include protective qualities for the pesticide, such as thick cell walls, pigmentation, and intracellular packaging or formation of inclusion bodies; leaf affinity; lack of mammalian toxicity; attractiveness to pests for ingestion; ease of killing and fixing without damage to the toxin; and the like. Other consideration include ease of formulation and handling, economics, storage stability, and the like.

Host organisms of particular interest include yeast, such as Rhodotorula sp., Aeurobasidium sp., Saccharomyces sp., and Sporobolomyces sp.; phylloplane organisms such Pseudomonas sp., Erwinia sp. and Flavobacterium sp.; or such other organisms as Escherichia, Lactobacillus sp., Bacillus sp., and the like. Specific organisms include Pseudomonas aeruginosa, Pseudomonas fluorescens, Saccharomyces cerevisiae, Bacillus thuringiensis, Escherichia coli, Bacillus subtilis, and the like.

The chimeric toxin-producing gene(s) can be introduced into the host in any convenient manner, either providing for extrachromosomal maintenance or integration into the host game.

Various constructs may be used, which include replication systems from plasmids, viruses, or centromeres in combination with an autonomous replicating segment (ars) for stable maintenance. Where only integration is desired, constructs can be used which may provide for replication, and are either transposons or have transposon-like insertion activity or provide for homology with the genome of the host. DNA sequences can be employed having the chimeric toxin-producing gene between sequences which are homologous with sequences in the genome of the host, either chromosomal or plasmid. Desirably, the chimeric toxin-producing gene(s) will be present in multiple copies. See for example, U.S. Pat. No. 4,399,216. Thus, conjugation, transduction, transfection and transformation may be employed for introduction of the gene.

A large number of vectors are presently available which depend upon eukaryotic and prokaryotic replication systems, such as ColEl, P-1 incompatibility plasmids, e.g., pRK290, yeast 2m .mu. plasmid, lembda, and the like.

Where an extrachromosomal element is employed, the DNA construct will desirably include a marker which allows for a selection of those host cells containing the construct. The marker is commonly one which provides for biocide resistance, e.g., antibiotic resistance or heavy metal resistance, complementation providing prototrophy to an auxotrophic host, or the like. The replication systems can provide special properties, such as runaway replication, can involve cos cells, or other special feature.

Where the chimeric toxin-producing gene(s) has transcriptional and translational initiation and termination regulatory signals recognized by the host cell, it will frequently be satisfactory to employ those regulatory features in conjunction with the gene. However, in those situations where the chimeric toxin-producing gene is modified, as for example, removing a leader sequence or providing a sequence which codes for the mature form of the pesticide, where the entire gene encodes for a precursor, it will frequently be necessary to manipulate the DNA sequence, so that a transcriptional initiation regulatory sequence may be provided which is different from the natural one.

A wide variety of transcriptional initiation sequences exist for a wide variety of hosts. The sequence can provide for constitutive expression of the pesticide or regulated expression, where the regulation may be inducible by a chemical, e.g., a metabolite, by temperature, or by a regulatable repressor. See for example, U.S. Pat. No. 4,374,927. The particular choice of the promoter will depend on a number of factors, the strength of the promoter, the interference of the promoter with the viability of the cells, the effect of regulatory mechanisms endogenous to the cell on the promoter, and the like. A large number of promoters are available from a variety of sources, including commercial sources.

The cellular host containing the chimeric toxin-producing pesticidal gene may be grown in any convenient nutrient medium, where the DNA construct provides a selective advantage, providing for a selective medium so that substantially all or all of the cells retain the chimeric toxin-producing gene. These cells may then be harvested in accordance with conventional ways and modified in the various manners described above. Alternatively, the cells can be fixed prior to harvesting.

Host cells transformed to contain chimeric toxin-producing DNA sequences can be treated to prolong pesticidal activity when the cells are applied to the environment of a target pest. This treatment can involve the killing of the host cells under protease deactivating or cell wall strengthening conditions, while retaining pesticidal activity.

The cells may be inhibited from proliferation in a variety of ways, so long as the technique does not deleteriously affect the properties of the pesticide, nor diminish the cellular capability in protecting the pesticide. The techniques may involve physical treatment, chemical treatment, changing the physical character of the cell or leaving the physical character of the cell substantially intact, or the like.

Various techniques for inactivating the host cells include heat, usually 50.degree. C. to 70.degree. C.; freezing; UV irradiation; lyophilization; toxins, e.g., antibiotics; phenols; anilides, e.g., carbanilide and salicylanilide; hydroxyurea; quaternaries; alcohols, antibacterial dyes; EDTA and amidines; non-specific organic and inorganic chemicals, such as halogenating agents, e.g., chlorinating, brominating or iodinating agents; aldehydes, e.g., glutaraldehyde or formaldehyde; toxic gases, such as ozone and ethylene oxide; peroxide; psoralens; desiccating agents; or the like, which may be used individually or in combination. The choice of agent will depend upon the particular pesticide, the nature of the host cell, the nature of the modification of the cellular structure, such as fixing and preserving the cell wall with crosslinking agents, or the like.

The cells generally will have enhanced structural stability which will enhance resistance to environmental degredation in the field. Where the pesticide is in a proform, the method of inactivation should be selected so as not to inhibit processing of the proform to the mature form of the pesticide by the target pest pathogen. For example, formaldehyde will crosslink proteins and could inhibit processing of the proform of a polypeptide pesticide. The method of inactivation or killing retains at least a substantial portion of the bioavailability or bioactivity of the toxin.

The method of treating the organism can fulfill a number of functions. First, it may enhance structural integrity. Second, it may provide for enhanced proteolytic stability of the toxin, by modifying the toxin so as to reduce its susceptibility to proteolytic degradation and/or by reducing the proteolytic activity of proteases naturally present in the cell. The cells are preferably modified at an intact stage and when there has been a substantial build-up of the toxin protein. These modifications can be achieved in a variety of ways, such as by using chemical reagents having a broad spectrum of chemical reactivity. The intact cells can be combined with a liquid reagent medium containing the chemical reagents, with or without agitation at temperatures in the range of about -10 to 60.degree. C. The reaction time may be determined empirically and will vary widely with the reagents and reaction conditions. Cell concentrations will vary form about 10E2 to 10E10 per ml.

Of particular interest as chemical reagents are halogenating agents, particularly halogens of atomic no. 17-80. More particularly, iodine can be used under mild conditions and for sufficient time to achieve the desired results. Other suitable techniques include treatment with aldehydes, such as formaldehyde and glutaraldehyde; anti-infectives, such as zephiran chloride and cetylpyridinium chloride; alcohols, such as isopropyl and ethanol; various histologic fixatives, such as Bouin's fixative and Helly's fixative (See: Humason, Gretchen L., Animal Tissue Techniques, W.H. Freeman and Company, 1967); or a combination of physical (heat) and chemical agents that prolong the activity of the toxin produced in the cell when the cell is applied to the environment of the target pest(s).

For halogenation with iodine, temperatures will generally range from about 0 to 50.degree. C., but the reaction can be conveniently carried out at room temperature. Conveniently, the iodination may be performed using triiodide or iodine at 0.5 to 5% in an acidic aqueous medium, particularly an aqueous carboxylic acid solution that may vary from about 0.5-5M. Conveniently, acetic acid may be used, although other carboxylic acids, generally of from about 1 to 4 carbon atoms, may also be employed. The time for the reaction will generally range from less than a minute to about 24 hrs, usually from about 1 to 6 hrs. Any residual iodine may be removed by reaction with a reducing agent, such as dithionite, sodium thiosulfate, or other reducing agent compatible with ultimate usage in the field. In addition, the modified cells may be subjected to further treatment, such as washing to remove all of the reaction medium, isolation in dry form, and formulation with typical stickers, spreaders, and adjuvants generally utilized in agricultural applications, as is well known to those skilled in the art.

Of particular interest are reagents capable of crosslinking the cell wall. A number of reagents are known in the art for this purpose. The treatment should result in enhanced stability of the pesticide. That is, there should be enhanced persistence or residual activity of the pesticide under field conditions. Thus, under conditions where the pesticidal activity of untreated cells diminishes, the activity of treated cells remains for periods of from 1 to 3 times longer.

The cells can be formulated for use in the environment in a variety of ways. They can be employed as wettable powders, granules, or dusts, by mixing with various inert materials, such as inorganic minerals (phyllosilicates, carbonates, sulfates, or phosphates) or botanical materials (powdered corncobs, rice hulls, or walnut shells). The formulations can include spreader/sticker adjuvants, stabilizing agents, other pesticidal additives, or surfactants. Liquid formulations can be aqueous-based or non-aqueous and employed as foams, gels, suspensions, emulsifiable concentrates, and the like. The ingredients can include rheological agents, surfactants, emulsifiers, dispersants, polymers, and the like.

The pesticidal concentration will vary depending upon the nature of the particular formulation, e.g., whether it is a concentrate or to be used undiluted. The pesticide will generally be present at a concentration of at least about 1% by weight, but can be up to 100% by weight. The dry formulations will have from about 1 to 95% by weight of the pesticide, while the liquid formulations will generally be from about 1 to 60% by weight of the solids in the liquid phase. The formulations will generally have from about 1E2 to 1E8 cells/mg.

The formulations can be applied to the environment of the pest(s), e.g., plants, soil or water, by spraying, dusting, sprinkling, or the like. These formulations can be administered at about 2 oz (liquid or dry) to 2 or more pounds per hectare, as required.

Following are examples which illustrate procedures, including the best mode, for practicing the invention. These examples should not be construed as limiting. All percentages are by weight and all solvent mixture proportions are by volume unless otherwise noted.

EXAMPLE 1

Construction of plasmid pEW1

The k-1 gene is the hd-1 gene described by Schnepf et al. (J. Biol. Chem. 260:6264-6272 1985). The k-1 gene was resected from the 5' end with Bal31 up to position 54. To this position was added a SalI linker (5'GTCCGACC3'). The 3' end of the gene was cleaved at position 4211 with the enzyme NdeI and blunt ended with the Klenow fragment of DNA polymerase.

The cloning vector pUC8 (Messing, J. and Vieira, J. [1982] Gene 19:269-276) which can be purchased from Pharmacia, Piscataway, N.J., was cleaved with SalI and EcoRI and cloned into plasmid pBR322 which had been cut with the same enzymes. The trp promoter (Genblock, available from Pharmacia) was blunt ended at the 5' end with Klenow and inserted into this hybrid vector by blunt end ligation of the 5' end to the SmaI site of the vector, and by insertion of the 3' end at the SalI site of the vector. The k-1 gene was then inserted using the SalI site at the 5' end and by blunt end ligation of the 3' end to the PvuII site of the vector. A schematic drawing of this construct, called pEW1, is shown in FIG. 1 of the drawings.

Plasmid pEW1 contains the DNA sequence encoding Bacillus thuringiensis toxin k-1.

EXAMPLE 2

Construction of plasmid pEW2

The k-73 gene is the HD-73 gene described by Adang et al. (Gene 36:289-300 1985). The k-73 gene was cleaved at position 176 with NsiI. The sequence was then cleaved at position 3212 with HindIII and the 3036 base fragment consisting of residues 176-3212 was isolated by agarose gel electrophoresis.

Plasmid pEW1, prepared as described in Example 1, was also cleaved with HindIII (position 33456 in Table 1, SEQ ID NO:1) and partially digested with NsiI (position 556 in Table 1, SEQ ID NO:1). The 3036 base fragment from k-73, disclosed above, was inserted into the NsiI to HindIII region of pEW1 replacing the comparable fragment of the k-1 gene, and creating plasmid pEW2. A schematic diagram of pEW2 is shown in FIG. 2 of the drawings.

Plasmid pEW2 contains the DNA sequence encoding Bacillus thuringiensis toxin k-73.

EXAMPLE 3

Construction of plasmid pEW3

The k-1 gene was cut with SacI at position 1873.

The gene was then submitted to partial digestion with HindIII and the 1427 base fragment consisting of residues 1873 to 3345 was isolated by agarose gel electrophoresis. Plasmid pEW2 was cut with SacI and HindIII and the large fragment representing the entire plasmid minus the SacI to HindIII fragment of the k-73 gene was isolated by agarose gel electrophoresis. The 1427 base fragment from the k-1 gene was then ligated into the SacI to HindIII region of pEW2, creating plasmid pEW3. A schematic diagram of pEW3 is shown in FIG. 3 of the drawings.

Plasmid pEW3 contains the DNA sequence encoding Bacillus thuringiensis chimeric toxin k-73/k-1 (pHY).

The nucleotide sequence encoding the chimeric toxin is shown in Table 1 (SEQ ID NO:1). The deduced amino acid sequence is shown in Table 1A (SEQ ID NO:2).

EXAMPLE 4

Construction of plasmid pEW4

The k-1 gene was cut at position 556 with NsiI. The gene was then cut with SacI at position 1873 and the 1317 base fragment from NsiI to SacI was isolated by agarose gel electrophoresis. Plasmid pEW2 was cut with SacI and then submitted to partial digestion with NsiI. The large fragment representing the entire plasmid, minus the NsiI to SacI region of the k-73 gene, was isolated by agarose gel electrophoresis. The 1317 base NsiI to SacI fragment of gene k-1 was then ligated into NsiI to SacI region of pEW2 to create plasmid pEW4. A schematic diagram of pEW4 is shown in FIG. 4 of the drawings.

The nucleotide sequence encoding the chimeric toxin is shown in Table 2 (SEQ ID NO:3). The deduced amino acid sequence is shown in Table 2A (SEQ ID NO:4).

Plasmid pEW4 contains the DNA sequence encoding Bacillus thuringiensis chimeric toxin k-1/k-73 (PYH).

EXAMPLE 5

Insertion of Chimeric Toxin Genes Into Plants

Genes coding for chimeric insecticidal toxins, as disclosed herein, can be inserted into plant cells using the Ti plasmid from Agrobacter tumefaciens. Plant cells can then be caused to regenerate into plants (Zambryski, P., Joos, H., Gentello, C., Leemans, J., Van Montague, M. and Schell, J. [1983] EMBO J. 2:2143-2150; Bartok, K., Binns, A., Matzke, A. and Chilton, M. D. [1983] Cell 32:1033-1043). A particularly useful vector in this regard is pEND4K (Klee, H. J., Yanofsky, M. F. and Nester, E. W. [1985] Bio/Technology 3:637-642). This plasmid can replicate both in plant cells and in bacteria and has multiple cloning sites for passenger genes. Toxin genes, for example, can be inserted into the BamHI site of pEND4K, propagated in E. coli, and transformed into appropriate plant cells.

EXAMPLE 6

Cloning of B. thuringiensis genes into baculoviruses

Genes coding for Bacillus thuringiensis Chimeric toxins, as disclosed herein, can be cloned into baculoviruses such as Autographa californica nuclear polyhedrosis virus (AcNPV). Plasmids can be constructed that contain the AcNPV genome cloned into a commercial cloning vector such as pUC8. The AcNPV genome is modified so that the coding region of the polyhedrin gene is removed and a unique cloning site for a passenger gene is placed directly behind the polyhedrin promoter. Examples of such vectors are pGP-B6874, described by Pennock et al. (Pennock, G. D., Shoemaker, C. and Miller, L. K. [1984] Mol. Cell. Biol. 4:399-406), and pAC380, described by Smith et al. (Smith, G. E., Summers, M. D. and Fraser, M. J. [1983] Mol. Cell. Biol. 3:2156-2165). The genes coding for k-1, k-73, k-73/k-1, k-1/k-73, or other B.t. genes can be modified with BamHI linkers at appropriate regions both upstream and downstream from the coding regions and inserted into the passenger site of one of the AcNPV vectors.

EXAMPLE 7

Chimeric Toxin Denoted ACB-1

Enhanced toxicity against all three insects tested was shown by a toxin denoted ACB-1. The toxin ACB-1 (Table 3A, SEQ ID NO:6) is encoded by plasmid pACB-1 (Table 3, SEQ ID NO:5). The insecticidal activity encoded by pACB-1, in comparison with pEW3 (Example 3), is as follows:

______________________________________ LC.sub.50 (O.D..sub.575 /ml)Clone T. ni H. zea S. exigua______________________________________pEW3 4.3 23.0 12.3pACB-1 1.2 3.9 1.2______________________________________ The above test was conducted using the conditions described previously.

The above results show that the ACB-1 toxin has the best composite activity as compared to the other toxins tested herein against all three insects.

Plasmid pACB-1 was constructed between the variable region of MTX-36, a wild B. thuringiensis strain, having the deposit accession number NRRL B-18101, and the variable region of HD-73 as follows: MTX-36; N-terminal to SacI site. HD-73; SacI site to C-terminal.

Total plasmid DNA was prepared from strain MTX-36 by standard procedures. The DNA was submitted to complete digestion by restriction enzymes SpeI and DraI. The digest was separated according to size by agarose gel electrophoresis and a 1962 bp fragment was purified by electroelution using standard procedures.

Plasmid pEW3 was purified and digested completely with SpeI and then submitted to partial digestion with DraI. The digest was submitted to agarose gel electrophoresis and a 4,138 bp fragment was purified by electroelution as above.

The two fragments (1962 bp from MTX-36 and 4138 bp from pEW3 were ligated together to form construct pACB.

Plasmid DNA was prepared from pACB, digested completely with SacI and NdeI and a 3760 bp fragment was isolated by electroelution following agarose gel electrophoresis.

Plasmid pEW1 was digested completely with SacI and NdeI and a 2340 bp fragment was isolated by electroelution following agarose gel electrophoresis.

The two fragments (3760 bp from pACB and 2340 from pEW1) were ligated together to form construct pACB-1.

The complete nucleotide sequence of the ACB-1 gene was determined and the deduced amino acid sequence of the toxin was compared with that determined for the toxin encoded by pEW3 (EW3). The result was that the deduced amino acid sequence of the ACB-1 toxin was identical to that of EW3 with two exceptions: (1) Aspartic acid residue 411 in EW3 was changed to asparagine in ACB-1 and (2) glycine residue 425 in EW3 was changed to glutamic acid in ACB-1. These two amino acid changes account for all of the changes in insect toxicity between these strains. The amino acid sequence of the EW3 toxin is as reported in Table 1 (SEQ ID NO:1). A schematic representation of these two toxins is as follows: ##STR1##

The above disclosure is further exemplification of the subject invention process for altering the host range of Bacillus toxins which comprises recombining in vitro the variable region of two or more toxin genes. Once a chimeric toxin is produced, the gene encoding the same can be sequenced by standard procedures, as disclosed above. The sequencing data can be used to alter other DNA by known molecular biology procedures to obtain the desired novel toxin. For example, the above-noted changes in the ACB-1 gene from HD-73, makes it possible to construct the ACB-1 gene as follows:

Plasmid pEW3, NRRL B-18034, was modified by altering the coding sequence for the toxin. The 151 bp DNA fragment bounded by the AccI restriction site at nucleotide residue 1199 in the coding sequence, and the SacI restriction site at residue 1350 were removed by digestion with the indicated restriction endonucleases using standard procedures. The removed 151 bp DNA fragment was replaced with the following synthetic DNA oligomer by standard procedures:

All other amino acids encoded by these genes are identical.

The changes made at positions 411 and 425, discussed above, clearly illustrate the sensitivity of these two positions in toxin EW3. Accordingly, the scope of the invention is not limited to the particular amino acids depicted as participating in the changes. The scope of the invention includes substitution of all 19 other amino acids at these positions. This can be shown by the following schematic: ##STR2## wherein X is one of the 20 common amino acids except Asp when the amino acid at position 425 is Gly; Y is one of the 20 common amino acids except Gly when the amino acids at position 411 is Asp. The 20 common amino acids are as follows: alanine, arginine, asparagine, aspartate, cysteine, glutamine, glutamate, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine.

EXAMPLE 8

Chimeric Toxin Denoted SYW1

Enhanced toxicity against tested insects was shown by a toxin denoted SYW1. The toxin SYW1 (Table 4A, SEQ ID NO:8) is encoded by plasmid pSYW1 (Table 4, SEQ ID NO:7). The insecticidal activity encoded by pSYW1, in comparison with pEW1 (Example 1) and pEW2 (Example 2), is as follows:

______________________________________ LC.sub.50 (O.D..sub.575 /ml)Clone T. ni H. zea S. exigua______________________________________pEW1 3.5 12.3 18.8pEW2 1.4 52.3 5.9pSYW1 0.7 1.9 12.0______________________________________ The above test was conducted using the conditions described previously.

Plasmid pSYW1 was constructed as follows:

Plasmid DNA from pEW2 was prepared by standard procedures and submitted to complete digestion with restriction enzyme AsuII followed by partial digestion with EcoRI. A 5878 bp fragment was purified by electroelution following agarose gel electrophoresis of the digest by standard procedures.

Plasmid DNA from strain HD-1 was prepared and submitted to complete digestion with restriction enzymes AsuII and EcoRI. A 222 bp fragment was purified by electroelution following agarose gel electrophoresis of the digest.

The two fragments (5878 bp from pEW2 and 222 bp from HD-1) were ligated together, by standard procedures, to form construct pSYW1.

The amino acid changes (3) in toxin SYW1 from EW3 are as follows: (1) Arginine residue 289 in EW3 was changed to glycine in SWY1, (2) arginine residue 311 in EW3 was changed to lysine in SYW1, and (3) the tyrosine residue 313 was changed to glycine in SYW1. A schematic representation of these two toxins is as follows: ##STR3##

The changes made at positions 289, 311, and 313, discussed above, clearly illustrate the sensitivity of these three positions in toxin EW3. Accordingly, the scope of the invention is not limited to the particular amino acids depicted as participating in the changes. The scope of the invention includes substitution of all the common amino acids at these positions. This can be shown by the following schematic: ##STR4## wherein X is one of the 20 common amino acids except Arg when the amino acid at position 311 is Arg and the amino acid at position 313 is Tyr; Y is one of the 20 common amino acids except Arg when the amino acid at position 289 is Arg and the amino acid at position 313 is Tyr; and Z is one of the 20 common amino acids except Tyr when the amino acid at position 289 is Arg and the amino acid at position 311 is Arg.

Construction of the SYW1 gene can be carried out by procedures disclosed above for the construction of the ACB-1 gene from plasmid pEW3 with appropriate changes in the synthetic DNA oligomer.

As is well known in the art, the amino acid sequence of a protein is determined by the nucleotide sequence of the DNA. Because of the redundancy of the genetic code, i.e., more than one coding nuclotide triplet (codon) can be used for most of the amino acids used to make proteins, different nucleotide sequences can code for a particular amino acid. Thus, the genetic code can be depicted as follows:

______________________________________Phenylalanine (Phe) TTK Histidine (His) CAKLeucine (Leu) XTY Glutamine (Gln) CAJIsoleucine (Ile) ATM Asparagine (Asn) AAKMethionine (Met) ATG Lysine (Lys) AAJValine (Val) GTL Aspartic acid (Asp) GAKSerine (Ser) QRS Glutamic acid (Glu) GAJProline (Pro) CCL Cysteine (Cys) TGKThreonine (Thr) ACL Tryptophan (Trp) TGGAlanine (Ala) GCL Arginine (Arg) WGZTyrosine (Tyr) TAK Glycine (Gly) GGLTermination signal TAJ______________________________________ Key: Each 3-letter deoxynucleotide triplet corresponds to a trinucleotide of mRNA, having a 5'-end on the left and a 3'-end on the right. All DNA sequences given herein are those of the strand whose sequence corresponds to the mRNA sequence, with thymine substituted for uracil. The letters stand for the purine or pyrimidine bases forming the deoxynucleotide sequence. A=Adenine G=guanine C=cytosine T=thymine X=T or C if Y is A or G S=C if Y is C or T Y=A, G, C or T if X is C Y=A or G if X is T W=C or A if Z is A or G W=C if Z is C or T Z=A, G, C or T if W is C Z=A or G if W is A QR=TC if S is A, G, C or T; alternatively QR=AG if S is T or C J=A or G K=T or C L=A, T, C or G M=A, C or T

The above shows that the novel amino acid sequence of the chimeric toxins, and other useful proteins, can be prepared by equivalent nucleotide sequences encoding the same amino acid sequence of the proteins. Accordingly, the subject invention includes such equivalent nucleotide sequences. In addition it has been shown that proteins of identified structure and function may be constructed by changing the amino acid sequence if such changes do not alter the protein secondary structure (Kaiser, E. T. and Kezdy, F. J. [1984] Science 223:249-255). Thus, the subject invention includes muteins of the amino acid sequences depicted herein which do not alter the protein secondary structure.

The one-letter symbol for the amino acids used in Tables 1A and 2A is well known in the art. For convenience, the relationship of the three-letter abbreviation and the one-letter symbol for amino acids is as follows:

______________________________________ Ala A Arg R Asn N Asp D Cys C Gln Q Glu E Gly G His H Ile I Leu L Lys K Met M Phe F Pro P Ser S Thr T Trp W Tyr Y Val V______________________________________
