研究方向
光是对于植物生长发育最重要的环境信号,本实验室多年来筛选获得了许多参与植物光形态建成的正向和负向调控因子,我们将深入解析这些因子之间的相互作用及其在光信号传导通路中的作用,我们还将寻找参与光信号通路的新因子,并探讨光与植物内源激素协同调控植物发育的机制。非编码RNA是不翻译成蛋白质而直接以RNA形式行使生物学功能的RNA分子,我们将探索中等长度非编码RNA参与和调控高等植物生长发育及环境信号响应的作用机理。杂种优势是杂交子一代在多个性状上优于其亲本的生物学现象,我们将以水稻和拟南芥为研究对象,在分子和细胞水平上解析杂种优势形成的遗传机理。我们还通过大数据的生物信息学分析和数学建模,开展水稻分子设计育种新技术的研究。
