主要研究内容:

1. 泛素蛋白酶体途径介导的蛋白修饰机制
泛素蛋白修饰(Ubiquitination)是真核生物特有的蛋白翻译后修饰,它直接地调节生命活动中有关时空特异变化的生物学功能。虽然已在泛素蛋白酶体系统调控植物正常生长发育以及植物对环境响应研究方面取得了一些进展,但对其详细的信号传导机理尚待进一步探讨。尤其是在植物与环境的相互作用领域,关于蛋白泛素修饰参与植物抵抗逆境胁迫的作用机制的研究还处于起步阶段。基于双子叶植物拟南芥及单子叶植物水稻的基因组学和遗传学较其它植物研究得更为深入,我们利用拟南芥和水稻为模式植物,着重于以下几个方面的研究:(1)从功能基因组学方面研究拟南芥中不同E2家族成员的共性及特异性,并且建立适合各种调控途径的体内外反应检测体系,研究E2与E3的特异性结合及生物学功能。(2)研究拟南芥和水稻中单亚基类泛素蛋白连接酶(E3)的两大重要家族(RING finger及 U-box家族)的功能,采取点面结合的方式,利用基因组学、生物化学及遗传学手段阐明该类蛋白的功能网络、作用对象及机制。(3)试图阐明泛素蛋白降解,特别是ERAD途径对植物生长发育的调控机制以及在植物逆境胁迫中的调控机制。

2. 植物与生物胁迫因子的相互作用及对非生物胁迫因子的响应及信号传导
我们分别利用正向和反向遗传学的方法,以模式植物拟南芥(Arabidopsis)为材料来研究植物对盐、干旱、冷等非生物胁迫的响应机制及信号传导途径,同时以模式植物小盐芥(Thellungiella salsuginea)来研究植物耐盐的分子机理。生长在华东地区海滩盐土上的本土植物种类小盐芥,符合作为遗传研究模式系统的各种标准,它的基因组大小接近拟南芥的两倍,但相对于拟南芥最高只能在75mM NaCl的浓度下完成其生活史,小盐芥则能在超过300mM NaCl浓度下完成生活史。因此,用小盐芥作为材料,通过系统的遗传学分析将有可能发现耐盐基因,揭示植物耐盐的分子机制。通过导入耐盐基因来获得抗逆的转基因经济作物,将扩大其种植范围和提高作物产量。


以双生病毒(Geminivirus)与植物的相互作用为模式研究植物与生物胁迫因子的相互作用。双生病毒是一组具有双生颗粒形态的单链环状植物DNA病毒。对双生病毒基因组结构、遗传表达机制、复制和转录调控机制及病毒与寄主的相互识别等方面进行深入研究,有助于揭示病毒与寄主植物相互间的作用方式。我们以甜菜曲顶卷叶病毒(Beet Curly Top Virus, BCTV)等双生病毒及模式植物拟南芥为材料, 结合基因组学、酵母双杂交系统及DNA芯片等技术来进行研究,目标是应用一种新的研究植物与病毒相互作用的方法研究植物与生物胁迫因子的相互作用,为防治由双生病毒引起的植物病害提出新的技术方案。

3. 高生物量植物--甜高粱的分子设计
甜高粱(Sweet Sorghum,Sorghum saccharatum)是耐旱、耐涝、耐盐碱等抗逆性强的光合效率极高的C4作物。茎秆中汁液含糖量与甘蔗相当。高生物量的甜高粱是高价值畜牧饲料、能源乙醇、造纸纤维和生物合成的基质。结合高通量基因组生物学技术和分子遗传学手段研究甜高粱的耐逆和高生物量分子机制,通过分子设计培育更适合边际土地生长的高生物量及抗逆性强的新品种。
