植物生物学
围绕microRNA基因网络的构建分析，阐明植物如何对内源信号和外源刺激协同应答以实现最优化生长，并据此改良作物性状。在模式植物拟南芥中整合转录因子染色质免疫沉淀测序数据、microRNA基因启动子分析、microRNA靶基因谱，构建转录因子-microRNA-靶基因网络。结合分子遗传学、细胞生物学、基因组学、数学建模等研究手段，解析以microRNA为中心的调控网络，加深和拓展对植物microRNA调控范畴的认知。通过诠释转录、转录后水平基因调控的有机耦合，阐明microRNA在植物生长发育与环境适应中广泛而重要的作用。同时结合比较基因组学和分子遗传学，旨在证明microRNA基因多样化、特异性地整合到基因调控网络之中的机制，是植物遗传多态性和表型多样化的一个重要成因，为生物多样性资源在农业上的应用提供新的思路。
