主要研究方向
细胞骨架与植物细胞生长调控

 高等植物的个体由众多形态各异的不同类型细胞所组成,植物细胞生长过程对于细胞乃至植物整体的生长发育和形态建成(morphogenesis)至关重要,我们实验室主要研究细胞骨架响应信号分子调控植物细胞生长和形态建成的分子机理。

 1、细胞骨架响应植物体内生长发育信号调控细胞极性生长。植物细胞的生长控制涉及分子和细胞水平诸多方面的调控。其中,细胞骨架已经被充分证明在植物细胞的生长以及形态建成方面有重要的功能。我们重点研究介导植物激素(如生长素)调控细胞生长的信号转导途径,包括植物中重要的信号分子ROP GTPase如何通过调控细胞骨架决定植物细胞极性生长和形态发生的分子调控机制,以及作用于细胞骨架的不同信号转导途径间的交互作用。同时也探讨ROPs-细胞骨架途径调控生长素极性运输的分子机制。不同信号途径对细胞骨架组织与动态的调控往往通过细胞骨架结合蛋白来完成,我们也致力发现新的细胞骨架结合蛋白或已知结合蛋白的新功能。

 2、细胞骨架响应环境信号调控细胞生长和气孔运动。环境中的信号(如光、非生物逆境胁迫信号等)对植物生长起重要调控作用。已有研究表明这些环境信号往往可以通过调节细胞骨架的组织、排列来调控植物细胞的生长,我们研究在这一过程中发挥功能的细胞骨架结合蛋白,以及传递信号的信号转导机制。此外,气孔运动的调控对于植物响应非生物逆境信号具有重要意义,而气孔运动依赖于细胞骨架。我们亦关注对细胞骨架调控气孔开放、闭合分子机制的深入解析。
