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.

所谓的双组分系统（TCS）为我们提供了原核生物（包括众多细菌物种）中信号转导系统的范例。 TCS 在信号感知和对各种环境刺激的适应性响应中发挥着重要和普遍的作用。然而，需要强调的是，在进化过程中，植物也进化出了复杂的TCS，这些TCS在植物发育中发挥着重要的生理作用，不仅包括植物激素细胞分裂素和乙烯感知和信号转导，还包括植物生物钟系统。为了更深入地了解TCS在植物中的生理作用，在本研究中，我们不仅使用了模式植物拟南芥，还使用了模式豆科植物Lotus japonicus和原始陆地苔藓小立碗藓。结果，我们对植物 TCS 有了一些新的见解，特别是关于细胞分裂素信号转导和生物钟的机制。这些结果已经发表在一系列报告中，多达 30 份。
