Patent ID: 7608751

Claim:
A method for generating or increasing the resistance of a plant to a plant pathogen of the phylum Oomyceta comprising increasing the activity of a Rpi-blb2 protein in the plant or a tissue, organ or cell of the plant or a part thereof by expressing a transgenic Rpi-blb2 protein encoding nucleic acid molecule, wherein the plant has increased resistance to the plant pathogen of the phylum Oomyceta, wherein said Rpi-blb2 protein encoding nucleic acid molecule is selected from the group consisting of: (a) a nucleic acid molecule encoding the polypeptide depicted in SEQ ID NO: 2 or 4; (b) a nucleic acid molecule comprising the coding sequence as depicted in SEQ ID NO: 3 or 5 or 6; and (c) a nucleic acid molecule encoding a polypeptide comprising a sequence having at least 95% identity to the amino acid sequence of the polypeptide encoded by the nucleic acid molecule of (a) or (b).
