| Research Abstract |
We first tested the effect of exposure to low temperature during early phases of rice endosperm development, then, revealed that low temperature inhibits the transition from syncytial phase to cellularization. Next, we found that high temperature facilitates formation of cellularized endosperm cells. We also performed expression and functional analyses of rice caryopsis specific genes and identified interacting proteins that bind caryopsis specific F-box proteins. Finally, we identified novel subtilisin-like protease genes that specifically expressed during early phases of rice endosperm development.
