| Outline of Final Research Achievements |
I have been previously found that the embryo facing endosperm region (EFR) is important for proper embryo-endosperm ratio of albuminous seed in rice. This study investigated the molecular mechanisms for developmental process of EFR, which was divided into three developmental phases (initiation, maintenance and regional determination). I performed the cytological characterization of EFR in 2-4 days after pollination, the cloning of EML1 gene involved in the initiation phase, RE3 gene involved in the maintenance phase and HER gene act downstream of GE gene to influence the regional determination. I inferred from these results that the oxygen sensing and auxin signaling molecules might be involved in the organization of EFR in rice.
