Fusarium head blight disease resistance

FIELD OF THE INVENTION

The current invention relates to resistance to Fusarium head blight disease. In particular, the invention relates to a gene contributing to resistance to Fusarium head blight disease and a recombinant construct including said gene. The invention also relates to plant cells transformed with the gene and plant material, including plant cell cultures, seeds and plants, comprising the transformed plant cells.

BACKGROUND OF THE INVENTION

Fusarium head blight (FHB) is a fungal disease in plants, in particular, in cereals such as wheat, barley and oats. It is caused by a Fusarium fungus, with the species Fusarium graminearum is the predominant causal agent of the disease in most areas of the world. In wheat, the fungus infects the head of the plant and causes the kernels to shrivel up. It can also produce a mycotoxin that further reduces the quality of kernel. These toxins can also be harmful to both animals and humans.

FHB in wheat is an economic presage and its post-harvest grain loss and considerable health risk to animals and humans due to accumulation of mycotoxin deoxynivalenol (DON), are well known. Given the economic concern of FHB, several control strategies have been developed to avert FHB epidemics. These include resistance cultivars and systems for the control of FHB and both chemical and biological control.

The use of host resistance is considered to be an efficacious means to control FHB in wheat and several approaches have been described previously. Breeding and selection of crossed lines for durable resistance to disease and yield stability take time and lines behave differently in different environments. There is also the chance of resistance breakdown in lines developed with this approach.

Definitions

Where used herein and unless specifically indicated otherwise, the following terms are intended to have the following meanings in addition to any broader (or narrower) meanings the terms might enjoy in the art:

Unless otherwise required by context, the use herein of the singular is to be read to include the plural and vice versa. The term “a” or “an” used in relation to an entity is to be read to refer to one or more of that entity. As such, the terms “a” (or “an”), “one or more,” and “at least one” are used interchangeably herein.

In the specification, the terms “comprise, comprises, comprised and comprising” or any variation thereof and the terms “include, includes, included and including” or any variation thereof are considered to be totally interchangeable and they should all be afforded the widest possible interpretation and vice versa.

“TaLRRK-6D” when used here in means a gene that is capable of enhancing or providing resistance to FHB in plants. It is a transmembrane kinase protein belonging to the LRR-RLK family. It has a nucleotide sequence of 3096 nucleotides in length and an amino acid sequence of 1031 amino acids in length and has a signal peptide, leucine rich repeats (LLR) domain, a transmembrane domain and a kinase domain. It has a nucleotide sequence of SEQ ID NO. 1 or a variant thereof.

“FHB resistance” as defined herein is the reduction of FHB growth on or in the plant. FHB resistance may be measured by a decrease, or an absence, of FHB symptoms in plants. This may be determined by the method of Example 2.

The phrase “FHB symptoms” when used herein refers to an effect of infection with FHB and includes, but is not limited to, one or more of damage of spikelets, premature discolouration and/or bleaching of spikelets, deoxynivalenol mycotoxin contamination of grain, and shriveling and/or wrinkling of kernels. Methods of analysing the phenotypic effects are known in the art.

As used herein the term “variant thereof” should be understood to mean a sequence which is substantially identical to a given sequence, but which is altered in respect of one or more amino acid residues or nucleotide residues compared to the given sequence, in such a way so as not to significantly alter the claimed function. Typically, the variant is a (nucleotide or amino acid) sequence having from about 30% to about 99% sequence identity with a given sequence. Generally, the variant is a (nucleotide or amino acid) sequence having from about 70% to about 99% sequence identity, preferably 70, 75, 80, 85, 86, 88, 87, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98 or 99%, sequence identity with a given sequence and which is typically capable of enhancing or providing resistance to FHB in plants, i.e. variant is a functional variant. Such alterations include, insertion, addition, deletion and/or substitution of an amino acid residue(s), or a nucleotide residue(s). There may be 1, 2, 3, 4, or 5 alterations. It will be appreciated that such variants may be naturally occurring variants or may be a non-natural variant. The term variant also includes a fragment of a sequence. In relation to a variant of a peptide, the insertion, addition and substitution with natural and modified amino acids are envisaged. The variant may have conservative amino acid changes, wherein the amino acid being introduced is similar structurally, chemically, or functionally to that being substituted.

The term “functional variant” when used herein is taken to mean a variant of SEQUENCE ID NO. 1 or SEQUENCE ID NO. 2, which is capable of enhancing or providing resistance to FHB in plants.

The term “fragment” means a segment of a given sequence. Typically, the fragment has from about 10 to 1000 contiguous amino acids, preferably about 50, 100, 200, 300, 400, 500, 600, 700, 800, or 900 amino acids. Typically, the fragment has from 10 to 3000 contiguous nucleotides preferably about 100, 250, 500, 750, 1000, 1250, 1500, 1750, 2000, 2250, 2500 or 2750 nucleotides. The fragment is a functional fragment, i.e., it is a segment of SEQUENCE ID NO. 1 or SEQUENCE ID NO. 2 which is capable of enhancing or providing resistance to FHB in plants. Functional fragments of functional variants of the invention are also provided.

In terms of “sequence homology”, the term should be understood to mean that a variant (or homolog) which shares a defined percent similarity or identity with a reference sequence when the percentage of aligned residues of the variant (or homolog) are either identical to, or conservative substitutions of, the corresponding residues in the reference sequence and where the variant (or homolog) shares the same function as the reference sequence.

In this specification, “homology”, “identity” or “similarity” refers to the relationship between two peptides or two nucleotide sequences based on an alignment of the sequences. The term “identity” when used herein means the percentage of identical, or conservative substitutions of, amino acid or nucleotide residues at corresponding positions in two sequences when the sequences are aligned and is across the entire length of the sequence, i.e. a variant (or homolog) that shares 70% sequence identity with a reference sequence is one in which any 70% of aligned residues of the variant (or homolog) are identical to, or conservative substitutions of, the corresponding residues in the reference sequence across the entire length of the sequence. For sequence comparison, one sequence acts as a reference sequence, to which test sequences are compared.

This alignment and the percent homology, similarity or sequence identity can be determined using software programs known in the art, for example, BLAST, EMBOSS Needle or Clustal Omega, using default parameters. Details of these programs can be found at the following Internet address: http://www.ncbi.nlm.nih.gov.

As used herein, the term “genetically modified” as applied to a cell, including a microorganism, means genetically engineered using recombinant DNA technology, and generally involves the step of synthesis of a suitable expression vector (see below) and then transfecting (i.e. stably or transiently) the expression vector into a host cell (generally stable transfection).

As used herein, the term “recombinant cell”, “transformed cell”, “recombinant plant” or “transformed plant” refers to a cell or plant comprising an exogenous nucleic acid stably integrated into the cellular genome that comprises a nucleotide sequence coding for TaLRRK-6D. In another embodiment, it may be a cell comprising a non-integrated (i.e., episomal) exogenous nucleic acid, such as a plasmid, cosmid, phagemid, or linear expression element, which comprises a sequence coding suitable for expression of a gene. In other embodiments, the present invention provides a cell line produced by stably transfecting a host cell, such as a plant host cell, with a plasmid comprising an expression vector of the invention. In one embodiment, the cell is engineered for heterologous expression of a gene.

The term “encode” as it is applied to nucleotide sequences refers to a nucleotide which is said to “encode” a polypeptide or peptide if, in its native state or when manipulated by methods well known to those skilled in the art, it can be transcribed and/or translated to produce the mRNA for the polypeptide and/or a fragment thereof.

The terms “polypeptide”, “peptide” and “protein” are used interchangeably herein to refer to a polymer of amino acid residues. The terms also apply to amino acid polymers in which one or more amino acid residues is a modified residue, or a non-naturally occurring residue, such as an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers. The peptide may or may not be “isolated”, that is to say removed from the components which exist around it when naturally occurring.

The term “amino acid” as used herein refers to naturally occurring and synthetic amino acids, as well as amino acid analogues and amino acid mimetics that have a function that is similar to naturally occurring amino acids. Naturally occurring amino acids are those encoded by the genetic code, as well as those modified after translation in cells (e.g. hydroxyproline, gammacarboxyglutamate, and O-phosphoserine). The phrase “amino acid analogue” refers to compounds that have the same basic chemical structure (an alpha carbon bound to a hydrogen, a carboxy group, an amino group, and an R group) as a naturally occurring amino acid but have a modified R group or modified backbones (e.g. homoserine, norleucine, methionine sulfoxide, methionine methyl sulphonium). The phrase “amino acid mimetic” refers to chemical compounds that have different structures from, but similar functions to, naturally occurring amino acids. It is to be appreciated that, owing to the degeneracy of the genetic code, nucleic acid molecules encoding a particular polypeptide may have a range of polynucleotide sequences. For example, the codons GCA, GCC, GCG and GCT all encode the amino acid alanine. The term “nucleic acid molecule” when used herein to include unmodified DNA or RNA or modified DNA or RNA. For example, the nucleic acid molecules or polynucleotides of the disclosure can be composed of single- and double stranded DNA, DNA that is a mixture of single- and double-stranded regions, single- and double-stranded RNA, and RNA that is a mixture of single- and double-stranded regions, hybrid molecules comprising DNA and RNA that may be single-stranded or, more typically double-stranded or a mixture of single- and double-stranded regions. In addition, the nucleic acid molecules can be composed of triplestranded regions comprising RNA or DNA or both RNA and DNA. The nucleic acid molecules of the disclosure may also contain one or more modified bases or DNA or RNA backbones modified for stability or for other reasons. “Modified” bases include, for example, tritiated bases and unusual bases such as inosine. A variety of modifications can be made to DNA and RNA; thus “nucleic acid molecule” embraces chemically, enzymatically, or metabolically modified forms. The term “polynucleotide” shall have a corresponding meaning.

In this specification, the term “plant material” should be understood to mean any constituent of a plant comprising plant cells, including a plant cell, plant cell culture, plant tissue, plant, or seed from a plant.

The term “cell” should be understood to mean a cell from a plant. In a particularly preferred embodiment, the cell is a plant cell selected from the group consisting of: maize, rice, wheat, barley, sorghum, millet, oats, soybean and rye. The term “transgenic cell” should be understood to mean a cell that comprises a transgene incorporated, ideally stably incorporated, into its genome.

The term “transformation platform” should be understood to mean the genetic machinery required to transfer the transgene into a cell, and generally comprises an organism, for example a bacteria, capable of mediating cellular transformation and containing a recombinant construct of the invention. Examples of transformation platforms include E. coli, A. tumefaciens, E. adhaerens, and certain “transbacter” strains of bacteria. Other examples include: biolistic transformation and floral dipping.

The term “transgene” should be understood to mean the nucleotide of the invention, and functional variants thereof.

The term “overexpression” refers to expression of a gene or protein in an increased quantity relative to the wild-type. In one embodiment, the expression may be enhanced by transfection of an expression vector containing the necessary machinery to express TaLRRK-6D into a host cell. The expression may be enhanced by a promoter to produce multiple copies of mRNA and large quantities of the selected product TaLRRK-6D. The host cell may already express endogenous TaLRRK-6D.

The phrase “nucleotide of the invention” when used herein refers to SEQUENCE ID NO. 1 or a functional variant thereof or a functional fragment thereof.

The phrases “amino acid sequence of the invention” or “peptide of the invention” when used herein refer to SEQUENCE ID NO. 2 or a functional variant thereof or a functional fragment thereof.

DETAILED DESCRIPTION

The current inventors have surprisingly found that TaLRRK-6D is highly induced in response to FHB in wheat heads of resistant cultivars and that gene silencing leads to an increase in FHB symptoms.

The current invention provides a gene for resistance to Fusarium head blight (FHB) in plants.

More specifically, the current invention provides a specific wheat (genome D homologue) of a leucine rich receptor kinase gene, TaLRRK-6D and a variant thereof for resistance to FHB in plants. The gene of the invention is termed TaLRRK-6D. TaLRRK-6D is restricted to the Poaceace Family (FIG. 1). It is found across the plant species but is confined to cereal family (FIG. 2).

Advantageously, as TaLRRK-6D is a native gene from the cultivars, the risk of resistance breakdown is greatly reduced. This provides longer and sustainable resistance in all conditions and genetic background.

TaLRRK-6D is a transmembrane kinase protein belonging to the LRR-RLK family. It has an amino acid sequence of 1031 amino acids in length and has a signal peptide, leucine rich repeats (LLR) domain, a transmembrane domain and a kinase domain.

The gene of the invention, TaLRRK-6D, has a nucleotide sequence of SEQUENCE ID NO.1 as follows:

EXAMPLES
Example 1

TaLRRK-6D gene expression in wheat heads

Study Description

To confirm that TaLRRK-6D homologue specifically was responsive to the fungus Fusarium, a quantitative RT-PCR assay was used to measure the level of gene expression in wheat heads treated with the fungus.

Strains

The deoxynivalenol producer Fusarium graminearum (strain GZ3639) was used in this study.

Method

Spikelets were inoculated with the deoxynivalenol producer Fusarium graminearum (strain GZ3639). Expression levels were tested up to 7 days (at day 1, 2, 3, 5 and 7) post fungal inoculation. The effect of the DON-non-producing mutant derivative of GZ3639, namely GZT40, on TaLRRK-6D expression was also analysed. The effect of TaLRRK-6D in wheat heads treated with mycotoxin DON was also analysed.

Results

The results showed that the TaLRRK-6D expression was early induced at 1 day post inoculation (dpi); with a peak of induction at 2 dpi, followed by a return to a basic level. This is illustrated by FIG. 3.

The induction of TaLRRK-6D expression by GZT40 was very low at all the days post inoculation (FIG. 3). The expression results for TaLRRK-6D in wheat heads treated with mycotoxin DON, showed significant increase of TaLRRK-6D transcript accumulation in response to the toxin. This was maximal at 1 dpi, and gradually reduced in the next few days (FIG. 3). From these results, it is evident that TaLRRK-6D is responsive to FHB and it is concluded that TaLRRK-6D is a component of the early host response to Fusarium fungi.

Example 2

TaLRRK-6D role in resistance to FHB

Study Description

The virus-induced gene silencing (VIGS) platform was used to validate TaLRRK-6D role in resistance to FHB in two wheat cultivars—the FHB resistant cv. CM82036 and the susceptible cv. Remus.

Strains

Wheat resistant cv. CM82036 and susceptible cv. Remus.

Methodology

Virus induced gene silencing: Two independent constructs were designed (BSMV:LRR1 and BSMV:LRR2) which target two distinct sequences of the TaLRR gene (FIG. 5). Plants comprising an empty vector (BSMV-00) which serves as a positive control and plants in which no construct was incorporated (negative control) were also included in the experiment. FIG. 6 is a pictorial representation of the two VIGS construct for its specificity to TaLRRK-6D. Constructs were applied to the flag leaves of the wheat cv. CM82036 and cv. Remus before emergence of the primary head. Two weeks later, two central spikelets were treated with FHB (16.9 mM) or mock 0.02% Tween20 treatment at mid anthesis (growth stage Zadoks 65). The phenotypic effect of FHB on plants at 7 and 14 days post-FHB treatment was also analysed by measuring the number of spikelets with FHB symptoms, e.g. discolouration.

Results

At 1 dpi, one spikelet above the one which had been treated was removed and used to measure the expression level of TaLRRK-6D by quantitative RT-PCR. Very low TaLRRK-6D expression was observed in the non-toxin treated plants (;mockTween treated), whether in the controls (FES), (BSMV:00) or silenced plants (BSMV:LRR1 and BSMV:LRR2) (FIG. 7).

In both cultivars, silencing reduced TaLRR-6D expression for both mock (no GZ3639) and Fusarium (GZ3639) treated samples (comparing BSMV:LRR 1 and BSMV:LRR2 versus BSMV:00). Silencing of TaLRRK-6D due to BSMV: LRR1 and BSMV: LRR2 plants treatment increased the FHB severity by 54.5% and 72.7% (as compared to mock and BSMV:00-treated plants) as illustrated in FIG. 8.

Plants treated with BSMV:LRR1 and BSMV:LRR2 were significantly more sensitive to FHB induced damage of spikelets than the non-silenced plants BSMV:00 (6.5 and 7.3 fold increase), as illustrated by FIG. 9. The TaLRRK-6D silenced spikelets showing FHB-induced damage was significantly reflected in yield reduction as compared to the BSMV:00 treatment (FIG. 10). This indicates a direct role of TaLRRK-6D in FHB resistance in wheat plants.

Example 3

Role of TaLRRK-6D in FHB in Barley

Study Description

In order to understand the role of TaLRRK-6D in Fusarium head blight in barley, wild type barley cv. Akashinriki lines were used.

Methodology

VIGS were used to silence LRR-RLK homolog in barley at 2nd leaf stage. Using detached leaf assay described by (Browne & Cooke, 2004), the effect of TaLRRK-6D silencing on the barley in response to F. culmorum strain FC200 was assessed. Leaves were point-inoculated with fungal conidia in the wild type cv. Akashinriki and the diseased leaf area monitored at 4 dai.

Results

The lines silenced with BSMV:LRR1 and BSMV:LRR2 developed severe lesions, and increased disease symptoms of 2.24 and 3 folds compared to BSMV:00 were observed (P<0.05) for Akashinriki silenced lines with construct BSMV:LRR1 and BSMV:LRR2 respectively as illustrated by FIG. 11. The number of conidia developed on the leaves at 4 dai was also determined and all two BSMV:LRR1 and BSMV:LRR2 silenced lines contained 20 224% and 293% more conidia than the wild type cv. Akashinriki that was treated with BSMV:00 was statistically significant (P<0.05) as illustrated by FIG. 12. The diseased leaf area monitored at 4 dai was found to be 5.8 cm2. Thus, the detached leaf results show that silencing of TaLRRK-6D leads to enhanced wheat leaf susceptibility to F. colmorum strain FC200.
