The effect of exposure to high or low temperature during early phases of rice endosperm development

我们首先测试了低温对水稻胚乳发育早期的影响，然后发现低温抑制了从合胞期到细胞化的转变。接下来，我们发现高温有利于细胞化胚乳细胞的形成。我们还进行了水稻颖果特异性基因的表达和功能分析，并鉴定了与颖果特异性F-box蛋白结合的相互作用蛋白。最后，我们发现了在水稻胚乳发育早期特异性表达的新的枯草杆菌样蛋白酶基因。

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.
