Research Summary
The goal of our research is to elucidate the mechanism of plant embryogenesis. We are focusing on processes of the pattern-ing of apical-basal or dorsal-ventral axis formation, and the organ-ogenesis during early stages of rice embryogenesis. We are taking a molecular genetic approach using a series of rice embryogenesis defective mutants as well as comparative embryology and genom-ics approaches in grass species. We are also responsible for man-aging, preservation, propagation, and distribution of rice genetic resources of wild rice species collected in the NIG under the NBRP.
