研究领域: 植物高光效及抗逆性机理 

1. 植物高光效机理及分子改良:深入解析C3植物光合/光呼吸分子调控机理,充分利用合成生物学、基因编辑、代谢工程等现代研究技术,重构光合/光呼吸代谢通路,在C3植物中创建新型光合CO2浓缩机制,以期提高作物光合效率、产量及抗逆性。

2. 植物活性氧(ROS)信号调控分子机理:光合/光呼吸与ROS产生及其信号转导密切相关。C3植物中70%H2O2源于光呼吸代谢,当植物遭遇干旱、高温、高光等逆境时其占比更高。我们发现光呼吸关键酶乙醇酸氧化酶(GLO)与过氧化氢酶(CAT)的动态互作/解离可作为调控H2O2波的一个分子开关(简称GC开关),这种基于代谢通道原理(metabolic channeling)的物理学发生机制尚属首次报道。目前正致力于深入解析GC开关调控的分子机理及其功能,以期为作物抗逆性分子改良提供理论与技术指导。

3. 植物草酸代谢调控分子机理:已有大量研究表明草酸在植物抗金属毒害、耐低磷等过程中起重要作用,但在可食性植物中含量过高会对人与动物产生毒害,因此阐明植物草酸代谢调控分子机理是合理有效控制草酸积累的前提。通过多年的研究探索,业已明确草酸代谢与光呼吸乙醇酸/乙醛酸代谢和硝同化紧密关联,目前正致力于进一步解析其代谢通路和分离克隆其代谢调控的关键基因,旨在最终实现合理有效调控草酸代谢以提高植物抗逆性的目标。
