研究领域 (Research focus):

研究植物光信号转导及其调控生物钟系统的分子机制。利用模式植物(拟南芥)深入解析蓝光受体隐花色素信号转导途径的组成及分子机制,以及光信号与生物钟系统的互作和调节机理,以求揭示光信号和生物钟系统介导植物生长发育及对环境适应性的未知分子机制。同时,本团队还开展竹类开花调控分子机理的研究。利用本中心的毛竹基因资源和麻竹遗传转化体系,开展竹类开花相关基因的克隆及功能解析,为揭示竹类开花的分子调控网络奠定基础。

Our research interests focus on dissecting the molecular mechanisms of plant light signaling transduction and circadian clock system. We use the model plant species, Arabidopsis, to identify the key components in blue light photoreceptor Cryptochrome signaling pathways and study their functions. We also investigate the mechanisms by which light signaling regulates circadian clock system, with the final goal to uncover the unknow molecular mechanisms that light and circadian clock control the plant growth and its adaptation to the ever-changing environment. Another research topic in our group is to study the molecular mechanism of flowering in bamboo. By using our bamboo gene resources and genetic transformation system, we work on homologous cloning of bamboo flowering genes and analyzing their functions both in model plant species (like Arabidopsis and rice) and bamboo itself, with the aim of depicting the basic molecular regulatory network of flowering in bamboo.
