Outline of Final Research Achievements

Self-incompatibility of angiosperm can be largely divided into homomorphic self-incompatibility, as found in Brassicaceae and Solanaceae, and heteromorphic self-incompatibility, as found in Primulaceae and Rubiaceae species with heterostyly. Whereas the molecular mechanism of the former has intensively been studied previously, little is known on how these two self-incompatibility systems relate to each other. In this study, I found that diallelic self-incompatibility, formerly only known from heterostylous plants, is widespread in Oleaceae and propose a new framework by which to understand the relationship between homomorphic and heteromorphic self-incompatibility
