研究工作

在农业生产中,高温、干旱等逆境胁迫是造成农作物减产的主要因素。叶绿体作为植物细胞中特有的细胞器,不仅是光合作用发生的场所,也是植物应对和适应逆境胁迫的重要调控单元。同时,叶绿体(以及其它相关质体)也是植物最重要的代谢中心,负责多种脂类、氨基酸、植物激素、色素的合成与降解,与许多重要的植物生物学过程和农艺性状有直接关联。而这些叶绿体功能的建立和维系,都依赖于叶绿体蛋白动态平衡(如蛋白转运、降解)的调控。本课题组主要以拟南芥、狗尾草和玉米为研究对象,围绕叶绿体蛋白调控机制这一中心问题,在光合作用、逆境反应和器官发育等关键领域开展研究。工作集中在以下3个方向:

1. 泛素-蛋白酶体途径降解叶绿体蛋白的分子机制

2. 叶绿体蛋白自噬的分子机制

3. 叶绿体蛋白调控在C4植物叶绿体分化中的功能
