Outline of Final Research Achievements

The purpose of this study was establishment of a novel tool(s) to easily identify genes involved in formation of the rice panicle, which is one of the most important traits determining the crop yield. For this purpose, we used the information of conventional panicle structural data, such as panicle length, primary rachis blanch number/length, and secondary rachis blanch number/length, and also new information about the expression level of all rice genes in the panicle meristems, to perform the QTL analysis based on panicle structural and expression traits. By combining these two QTL data, we could easily identify some good candidates for genes involved in panicle formation. We also performed a genome wide association study (GWAS) for such purpose and also succeeded to identify a few novel genes for panicle development. Based on these observations, we discussed the feasibility of new tools to easily identify novel genes involved in rice panicle formation.
