| Research Abstract |
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.
