| Outline of Final Research Achievements |
The objective of this study was to identify "key molecules" that function in the reproductive process of plants. Unilateral incompatibility in Japanese and Turkish lines of Brassica rapa, which are the same species, is due to the duplication of the self-incompatibility locus. It was clarified that after the gene duplication, unilateral incompatibility was caused by the gain or loss of function of the female factor. Furthermore, B. napus is a diploid of B. oleracea and B. rapa, and not only the self-incompatibility factor but also other factors regulate the incompatibility, suggesting that genome reorganization and epigenetic regulation occurred during the process of diploid stabilization, resulting in a complex genetic phenomenon.
