| Research Abstract |
Buckwheat （Fagopyrum esculentum） has a defective breeding trait, known as self-incompatibility. Thus, the yield of buckwheat is low and unstable comparing with other major self-fertilizing crops. In this study, by using multiple molecular genetic approaches such as mRNA sequence comparisons by new generation sequencing, we identified a new gene, S-LOCUS EARLY FLOWEING 3(S-ELF3) which is the most promising candidate gene for buckwheat self-incompatibility system. Our knowledge obtained from this study will enable to develop self-fertilizing buckwheatcultivars.
