Outline of Final Research Achievements

In land plants, photoperiod and light quality are major environmental factors to control growth phase transition. However, little is known about how plants evolved regulatory mechanisms in land plant evolution. Comparative genome analysis revealed that acquisition of circadian clock can be traced back to charophytes. Molecular genetic analysis using the model liverwort Marchantia polymorpha showed that the clocks were functional for rhythmic gene expression. The protein complex consisting of GI and FKF functioned downstream of the clocks, and controlled growth phase transition in the gametophyte generation. M. polymorpha has photoreceptor phytochrome and PIF as single copy genes, interacting to transduce red-light signaling. These findings suggest that the basic molecular mechanisms for light-dependent growth phase control were already established at the early stage of plant evolution.
