实验室研究方向:分子植物-病原菌互作
        植物如何识别病原菌并激活抗病,病原菌如何巧妙地躲避识别或抑制寄主抗性,专性寄生真菌如何与植物亲密共处是重要的生物学问题。同时,作物抗病也是重要的稳产性状,抗病品种的应用可以减少农药使用、保护环境。我们实验室采用大麦、小麦与白粉菌互作研究体系,通过遗传学、细胞生物学、生物化学和生物信息学等手段研究植物抗病和真菌致病的分子机理,为抗病育种提供理论基础和基因资源。
 
        1植物NLR免疫受体抗病机制
        利用大小麦与白粉菌互作体系,研究NLR类型抗病蛋白的抗病机制,探索这类抗病基因在抗病育种中的应用。大麦多个NLR免疫受体蛋白介导对白粉菌的ETI专化性抗病免疫,MLA在细胞质中诱导细胞死亡,在细胞核中与转录因子互作介导抗病。我们主要阐明抗病蛋白的功能、下游的信号组份、以及抗病转录调控的机制,建立抗病调控网络和鉴定下游靶标。
 
        2、植物与病原真菌互作跨界信号调控机制
        小分子RNA(sRNA)在植物与病原菌互作中发挥着重要的作用,植物或病原菌通过sRNA(miRNA、siRNA)跨界诱导RNA干扰(RNAi)从而调控病原菌致病性或植物抗病性,而大小麦白粉菌编码并分泌大量效应蛋白从而干扰或抑制寄主的抗病性,建立专性寄生关系。我们研究sRNA以及靶标的功能及调控,阐明效应蛋白作用机理及其靶标的功能。
 
        3、麦类作物抗病遗传及抗病基因克隆
        麦类作物真菌病害主要包括白粉病、锈病和赤霉病。我们研究大、小麦对病原真菌的抗病遗传,筛选抗病种质资源、挖掘抗病新位点,通过GWAS等方法关联抗病基因,对NLR目标基因进行富集和新一代测序并克隆抗病基因。
