Patent ID: 8067668

Claim:
A method of generating or increasing a resistance to at least one pathogen in plants, which comprises: a) reducing an amount, activity or function of an NADPH oxidase in a plant or a tissue, organ, part or cell thereof, and b) selecting plants in which, in comparison with corresponding wild type plants the resistance to at least one pathogen exists or is increased, wherein the reducing of step (a) comprises introducing into the plant, tissue, organ, part or cell thereof a nucleic acid encoding a double-stranded RNA of NADPH oxidase, and wherein the NADPH oxidase comprises: i) the polypeptide sequence as shown in SEQ ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 or 22, ii) a polypeptide sequence having at least 90% homology with the polypeptide sequence as shown in SEQ ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 or 22 and having the same function as the polypeptide sequence as shown in SEQ ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 or 22, iii) a polypeptide sequence encoded by the nucleic acid sequence as shown in SEQ ID NO: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 or 21, or iv) a polypeptide sequence encoded by a nucleic acid sequence having at least 90% homology with the nucleic acid sequence as shown in SEQ ID NO: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 or 21 and having the same function as the polypeptide sequence as shown in SEQ ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 or 22.
