    研究领域:

    主要研究领域
            植物光合复合体结构与功能
     
    研究内容
            利用生物信息学、遗传学、分子生物学和生物化学等手段探索植物光合作用碳反应过程中关键酶的结构与功能,解析光合作用碳反应调控分子机理,为农业育种提供理论依据与技术路线。
     
            研究主要集中在以下三个方面:解析核酮糖-1,5-二磷酸羧化酶/加氧酶(Rubisco)的生物合成途径,解析调控Rubisco活性的分子网络系统,筛选高效Rubisco从而提升植物光合作用效率;叶绿体分子伴侣Cpn60的组成、结构与功能调控研究;碳同化关键酶的活性与功能研究。
     
            1Rubisco生物合成、结构与功能研究
            Rubisco的生物合成是一个复杂的过程,Rubisco在分子伴侣辅助下完成正确折叠并在其他辅助蛋白的帮助下组装成全酶。利用分子信息学、分子生物学、生物化学和X射线晶体学手段,研究Rubisco折叠组装机制、解析Rubisco结构、挖掘影响Rubisco活性的重要位点与因素。
     
            2叶绿体分子伴侣Cpn60分子结构与功能研究
            叶绿体分子伴侣Cpn60在体内负责折叠多种蛋白质,协助细胞抵抗生物以及非生物胁迫。而且,Rubisco大亚基折叠到其天然状态绝对依赖Cpn60的作用。利用生物化学、遗传学手段研究Cpn60的组成与功能调控,解析其管家功能与胁迫功能。
     
            3、碳同化循环中酶活性、功能研究
            植物光合作用效率的提升还存在其他限制因素,本课题组从系统学角度出发,利用多种研究手段分析光合相关蛋白(酶)提升植物光合效率的协同效应和作用机制。
