摘要： Wild species of the genus Oryza are excellent gene pools for improvement of agronomic traits of Asian cultivated rice. The blast resistance gene Pi57(t) in the introgression line IL-E1454 derived from Oryza longistaminata was previously mapped on rice chromosome 12. Inoculation with 322 Magnaporthe oryzae isolates collected from 6 countries indicated that Pi57(t) conferred broad spectrum resistance against M. oryzae. Two mapping populations consisting of 29070 and 10375 F-2 plants derived from the crosses of resistant donor IL-E1454 with susceptible parents RD23 and Lijiangxintuanheigu respectively, were used for fine mapping of Pi57(t) locus. Based on genotyping and phenotyping results of recombinants screened from the two crosses, Pi57(t) was finally mapped to a 51.7-kb region flanked by two molecular markers (STS57-320 and STS57-372) on the short arm and close to the centromere of chromosome 12. Six candidate resistance genes were predicted in the target region according to the reference sequence of Nipponbare. These results could facilitate both marker-assisted selection for disease-resistant breeding and gene cloning.
