Outline of Final Research Achievements |
In plants, light plays critical roles in processes that accompany with cell proliferation, such as organogenesis and regeneration. For the liverwort Marchantia polymorpha, a bryophyte, red light promotes cell proliferation. This research project revealed that red light regulates different steps of expression of a gene that regulates S-phase entry by signaling via photosynthesis and the red-light receptor phytochrome, and that the phytochrome also promotes isotropic cell growth. Functional analysis on the microtubule-based motor protein that is localized to the cell plate suggested that the protein may play a role in the transport of membrane vesicles for cell-plate formation. As this gene was found to be essential, a vector and a protocol for obtaining conditional knockout mutants were created.
