Abstract
The present invention relates to a genetically modified plant which has enhanced resistance to one or more fungal pathogen(s).
Claims21
1-65. (canceled)
A plant having a genetically modified gene encoding an atypical cinnamoyl-CoA dehydrogenase 2 (CAD2) polypeptide, wherein when expressed in the plant the polypeptide confers enhanced resistance to one or more biotrophic fungal pathogen(s) when compared to a corresponding plant lacking the gene.
A process for identifying a polynucleotide encoding a polypeptide which confers enhanced resistance to one or more fungal pathogen(s) to a plant, the process comprising:
- i) obtaining a polynucleotide of claim 72 operably linked to a promoter,
- ii) introducing the polynucleotide into a plant,
- iii) determining whether the level of resistance to one or more fungal pathogen(s) is increased relative to a corresponding plant lacking the polynucleotide, and
- iv) optionally, selecting a polynucleotide which when expressed produces a polypeptide which confers enhanced resistance to one or more fungal pathogen(s).
An isolated and/or exogenous polynucleotide encoding a polypeptide which confers enhanced resistance to one or more fungal pathogen(s), wherein the polypeptide comprises amino acids having a sequence at least 40% identical to the amino acid sequence of any one or more of SEQ ID NO's 1 to 10 and 79 to 83.
A method for identifying a plant which has enhanced resistance to one or more fungal pathogen(s), the method comprising the steps of
- i) obtaining a sample from a plant, and
- ii) screening the sample for the presence or absence of an atypical cinnamoyl-CoA dehydrogenase 2 (CAD2) polypeptide which when expressed in the plant the polypeptide confers enhanced resistance to one or more biotrophic fungal pathogen(s) when compared to a corresponding plant lacking the gene, and/or screening the sample for the presence or absence of the polypeptide.
