Outline of Final Research Achievements

Sheath blight, caused by the soil-born fungus Rhizoctonia solani, is a major disease of rice. We previously identified sheath blight-resistant natural accessions of the small grass plant Brachypodium distachyon. In this study, we characterized these accessions and searched for the candidate genes that confer sheath blight resistance. A sheath blight-resistant accession, Bd3-1, suppressed the infection process of R. solani and activated salicylic acid-dependent immunity at an early stage of infection. Moreover, we identified eight candidate genes that might confer sheath blight resistance based on the QTL analysis using recombinant inbred lines between Bd3-1 and a sheath-blight susceptible accession, Bd21.
