Research Abstract

To understand molecular genetic mechanism of rice development, we focused on the genes such as G1, SHL2, DL, EG1 and FOS2, and revealed their function. The results obtained are likely to contribute for understanding of mechanism of flower and leaf development, and regulation of cell fate in the meristem in rice.
