摘要

expression cassettes, polypeptide, nucleic acid molecule, antipathogenic compositions, transformed microorganism, as well as methods for inducing plant pathogen resistance in a plant and for protecting a plant against a plant pathogen compositions and methods for protecting a plant against a pathogen, particularly a fungal pathogen, are provided. Compositions include novel amino acid sequences and variants and fragments thereof for anti-pathogenic polypeptides that have been isolated from microbial fermentation broths. Nucleic acid molecules comprising nucleotide sequences encoding the anti-pathogenic polypeptides of the invention are also provided. A method for inducing pathogen resistance in a plant using the nucleotide sequences disclosed herein is still provided. The method comprises introducing into an plant an expression cassette comprising a promoter operably linked to a nucleotide sequence encoding an anti-pathogenic polypeptide of the invention. Compositions comprising an anti-pathogenic polypeptide or a transformed microorganism comprising a nucleic acid of the invention in combination with a carrier and methods of using such compositions to protect a plant against a pathogen are further provided. transformed plants, plant cells, seeds and microorganisms comprising a nucleotide sequence encoding an anti-pathogenic polypeptide of the invention or variant or fragment thereof are also disclosed.
