<p>PROBLEM TO BE SOLVED: To obtain a gene resistant to rice blast, composed of a blast-resistant gene having a specific base sequence, capable of providing a blast-resistant rice capable of extremely reducing the amount of agrochemicals to be scattered by transducing the gene into a blast-sensitive rice, and usable for plant bleeding or the like. SOLUTION: This gene is the new blast-resistant gene having a base sequence of the formula. The gene enables a blast-resistant rice to be created by transducing a recombinant vector having the gene, into a blast-sensitive rice, and allows the amount of agrochemicals to be scattered to be reduced extremely. The gene is obtained by forming a genome library of blast-resistant rice species BL-1, and screening the library by using a neighborhood marker having a determined and specified position on a chromosome of a blast-resistant gene by the F2 analysis by using an F2 group obtained by hybridizing a blast-sensitive Indica species with a blast-sensitive Japonica species, and a nucleic acid marker.</p> |
