(57) [Problem] To provide a blast resistance gene Pi-b, a gene functionally equivalent thereto, and a protein encoded by these genes. Another object of the present invention is to produce a disease resistant plant using these genes. SOLUTION: In order to isolate the blast resistance gene Pi-b from a vast chromosomal region, a intensive study was carried out using a map-based cloning technique, and finally the desired gene was isolated. Reached. Since the isolated cDNA is a blast resistant gene, it was found that it is possible to produce a blast resistant plant using this gene or a similar gene. |
