我们实验室主要研究方向为植物分子遗传学与细胞壁生物学研究:
1、细胞壁形成与植物生长发育
植物如何形成细胞壁是一个重要的科学问题。作为植物细胞的基本结构,细胞壁的形成与植物生长发育密切相关。大量的研究表明,细胞壁形成的异常通常伴随着植物生长发育的异常。另外,作为基础代谢过程,细胞壁的合成与调控处于植物信号传导的最下游,植物对激素的反应、对环境的适应和对胁迫的应答最终会在细胞壁的形成和变化上体现出来。因此植物体内存在参与细胞壁形成及响应细胞壁改变的信号通路和应答机制。人们对这一过程的了解还极其不清楚。我们课题组通过研究矮秆、披叶等水稻突变体和拟南芥花粉管发育异常突变体及其野生型基因的功能,发现一些关键基因OsCSLD4 (Li et al., 2009) 、BC12(Zhang et al., 2010)、MGP4(Liu et al., 2011)、ILA1(Ning et al., 2011)等影响细胞有丝分裂或伸长过程,为揭示细胞壁形成及其在生长发育中的作用机制积累了数据。
2、细胞壁生物合成与水稻茎秆机械强度
茎秆强度是作物栽培育种中重要的农艺性状,与植株的抗倒伏性直接相关。主要由细胞壁、尤其是次生细胞壁提供,是其化学组成及物理结构的反映。目前对单子叶作物(如水稻)的茎秆强度分子机理研究还很不深入。本课题组独立或与李家洋院士实验室合作完成了BC14(Zhang et al., 2011)、BC3(Xiong et al., 2003)、BC12(Zhang et al., 2010)、BC11(Zhang et al., 2009)、BC10 (Zhou et al., 2009)等关键基因的图位克隆和功能研究工作。所开展的工作已涵盖从底物核苷酸糖运输到纤维素、非纤维素多糖合成与沉积,从膜泡转运到细胞骨架转换等细胞壁形成的重要过程。同时发现影响机械强度的重要 “出口”是纤维素的含量和纤维素微纤丝的排列。对于阐明作物茎秆强度这一重要农艺性状形成的分子机理及解决农业生产上存在的一些实际问题具有重要意义。
