【摘要】 附着胞的分化、形成和成熟是稻瘟病菌成功侵入寄主的前提.稻瘟病菌识别不同的胞外信号,可通过环化腺苷酸(cAMP)信号途径、丝分裂原激活蛋白激酶(Mitogen-activated protein kinase,MAPK)信号转导途径和Ca2+信号途径等不同的信号途径来调控附着胞发育.结合这些信号传递途径相关基因及其信号途径间关系的研究论述了调控稻瘟病菌附着胞分化和发育的信号传递的分子机理.更多还原

【Abstract】 Appressorium initiation,formation and maturation are prerequisites for penetrating into the host tissues by Magnaporthe grisea.As responses to a variety of extracellular signals,cAMP signaling,mitogen-activated protein kinase signaling,and Ca²⁺ signaling pathways can regulate appressorium development of the pathogen fungus.This review takes a brief walk down molecular mechanism of appressorium initiation,development of M.grisea based on three types of pathways above,focusing on which genes are involved in the pathways and what’s the relationship among these different pathways.更多还原
