2、稻减产的主要病因，水稻．稻瘟病菌及水稻白叶枯病原茵互作已成为研究植物一病原茵互作的模式系统。本研究归纳了目前已克隆的抗稻瘟病及白叶枯病基因与其分子结构和功能，概括了近年来鉴定的一些病原茵相关分子(Pathogen—associatedmolecularpatterns，s)及稻瘟病菌和白叶枯菌分泌的效应蛋白，并总结了针对稻瘟病菌和白叶枯茵介导的病原物分子诱导的抗病反应fPAMP—triggeredimmunity，PTI)和效应蛋白诱导的抗病·~A(Efector-triggeredimunity，ETI)~其信号传导途径的研究成果，指出效应蛋白一抗病蛋白间互作将为探索植物一病原菌间互作提
