- 研究方向
生物钟分子系统(Circadian molecular system)是生物体为了因应地球自转而产生的昼夜环境周期性的变化，从而进化出的协调细胞内基因表达，及代谢网络调控的分子系统。我们课题组以水稻和拟南芥为模式植物，解析植物生物钟分子系统组成以及对植物生长发育的调控机理，主要包括对开花时间调控、细胞生长以及如何协同细胞内代谢网络方面的分子机理研究。研究核心主要是围绕植物生物钟分子系统如何通过对环境信号的整合而实现对输出系统的控制，以期为提高农作物品质与产量提供时间生物学方面的理论依据和遗传资源。课题组主要研究方向为：
1.植物生物钟分子系统的组成解析及关键因子的转录后水平调控；
2.水稻生物钟分子系统的表观遗传控制分子机制；
3.生物钟分子系统对植物发育的调控及相关分子机理。
