| Outline of Final Research Achievements |
The rice grain as our important food corresponds to the endosperm of rice seed. Rice endosperm consists two types of tissues, namely starchy endosperm (SE) and the aleurone layer(AL). SE occupies the most of inside portion of the endosperm, whereas AL is mostly single cell layered tissue and positioned at the periphery of the endosperm.This research investigated the mechanisms whereby the two types of cells differentiate,using two newly screened mutants; one having extra cell layers of AL and the other forming ectopic AL-like cells in SE region. The results indicated that precise regulation of cell division and proliferation was essential for proper differentiation of the two cell types.
