| タイトル | Identification and mapping of Pi41, a major gene conferring resistance to rice blast in the Oryza sativa subsp. indica reference cultivar, 93-11. | |

Abstract: The Oryza sativa subsp. indica reference cultivar (cv.), 93-11 is completely resistant to many Chinese isolates of the rice blast fungus. Resistance segregated in a 3:1 (resistance/susceptible) ratio in an F(2) population from the cross between 93-11 and the japonica reference cv. Nipponbare, when challenged with two independent blast isolates. The chromosomal location of this monogenic resistance was mapped to a region of the long arm of chromosome 12 by bulk segregant analysis, using 180 evenly distributed SSR markers. Five additional SSR loci and nine newly developed PCR-based markers allowed the target region to be reduced to ca. 1.8 cM, equivalent in Nipponbare to about 800 kb. In the reference sequence of Nipponbare, this region includes an NBS-LRR cluster of four genes. The known blast resistance gene Pi-GD-3 also maps in this region, but the 93-11 resistance was distinguishable from Pi-GD-3 on the basis of race specificity. We have therefore named the 93-11 resistance Pi41. Seven markers completely linked to Pi41 will facilitate both marker-assisted breeding and gene isolation cloning. |
