Abstract
Methods for protecting a plant from a plant pathogenic fungus are provided. A method for enhancing fungal pathogen resistance in a plant using the nucleotide sequences disclosed herein is further provided. The method comprises introducing into a plant an expression cassette comprising a promoter operably linked to a nucleotide sequence that encodes an antifungal polypeptide of the invention. Transformed plants, plant cells, seeds, and microorganisms comprising a nucleotide sequence that encodes an antifungal polypeptide of the embodiments, or variant or fragment thereof, are also disclosed.
Claims19
A method for enhancing resistance of a plant to a pathogen, said method comprising:
- (a) stably transforming a plant cell with at least one expression cassette comprising a nucleotide sequence operably linked to a promoter that drives expression in a cell of said plant, wherein said nucleotide sequence has at least 95% sequence identity to SEQ ID NO:
- 6, and wherein said nucleotide sequence encodes a polypeptide that confers resistance against at least one plant fungal pathogen;
- and
- (b) regenerating a transformed plant from said plant cell, wherein the plant has enhanced resistance to said fungal pathogen as compared to a plant that does not comprise said expression cassette.
A transgenic plant having stably incorporated into its genome a polynucleotide sequence that is at least 95% identical to SEQ ID NO:
- 6, wherein said polynucleotide sequence encodes a polypeptide that confers resistance against at least one plant fungal pathogen, wherein said plant has improved resistance to said at least one plant pathogenic fungus, as compared to a control plant.
