| Research Abstract |
The so-called Two-Component Systems (TCS) provide us with the paradigm of signal transduction system in prokaryotes, including numerous bacterial species. TCS play important and general roles in signal perception and adaptive response to a variety of environmental stimuli. However, it should be emphasized that, during evolution, plants also have evolved sophisticated TCS, which now play important physiological roles in plant developments, including not only the phytohormone cytokinin and ethylene perception and signal transduction but also the plant circadian clock systems. In order to gain more fundamental insights into the physiological roles of TCS in plants, in this study we employed not only the model plant Arabidopsis thaliana, but also the model legume Lotus japonicus and the primitive land moss physcomitrella patens. As the results, we gained a number of new insights into the plant TCS, particularly, with regard to the mechanisms underlying cytokinin signal transduction and circadian clock. These results have already been published in a series of reports, as many as 30.
