Outline of Final Research Achievements

The objective of this study is cloning the QTL for resistance to bacterial grain rot, caused by the bacterial pathogen Burkholderia glumae, which is a destructive disease in heading stage of rice. We analyzed the backcrossed inbred lines derived from a cross between K (resistant) and H (susceptible). After substitution mapping, the QTL was located in a 12.7-kb interval and only one gene was annotated in the region.

Academic Significance and Societal Importance of the Research Achievements

本研究では、イネにおける代表的な開花期病害の一つであるもみ枯細菌病菌に対する抵抗性遺伝子の単離を目指し、抵抗性品種Kと罹病性品種Hを用いて作出した遺伝解析集団の抵抗性評価を進めることにより、予測遺伝子を1個に絞ることに成功した。もみ枯細菌病は、日本および世界で発生の増大が懸念されている病害であるが今まで抵抗性遺伝子を単離して機能を明らかにした報告はない。従って、本研究成果は、学術的および育種的に重要な知見である。
