Light signaling and growth phase transition in land plants

点击翻译按钮获取中文摘要

In the liverwort, Marchantia polymorpha, the transition from vegetative into reproductive phase is repressed under white fluorescent light, but we found that M. polymorpha rapidly develops into reproductive phase under far-red-rich light conditions. A series of reverse genetic approaches indicated that Pfr-type Mpphy represses the growth phase transition from vegetative to reproductive. I have also got several results suggesting that Mpphy was functional in the nucleus, and also alternate morphogenesis directly or indirectly through regulation of cell division.
