Outline of Final Research Achievements

Common buckwheat, Fagopyrum esculentum, is a heteromorphic self-incompatibility (SI) species. Its yield is relatively unstable compared to other major self-fertilizing crops due to heteromorphic SI. In this study, we attempted to identify the genes involved in heteromorphic SI of buckwheat. Noble two genes were found by transcriptome and genomic analyses, which were located to the S locus and to be expressed in the short-styled flower. These two genes are suitable candidate genes for the control of the short-styled phenotype of buckwheat plants. Our knowledge obtained from this study will enable to develop self-fertilizing buckwheat cultivars.
