摘　　要：由稻瘟病菌引起的稻瘟病是一种世界性病害,严重影响全球水稻生产。稻瘟病菌变异迅速,导致品种抗病和农药防治效果下降。因此,从分子层面揭示稻瘟病菌的致病机制,可以为水稻病害防治和新药开发提供靶位分子。利用野生稻内生真菌防治稻瘟病为水稻病害的绿色防控提供了新思路。探索野生稻内生真菌资源,挖掘具有促进生长、免疫诱抗和抗逆适应等功能的菌株,探明水稻与内生真菌的互作机制,为开发新型内生真菌生防制剂提供了基础理论。本综述重点总结了近年来稻瘟病菌致病机制新进展以及水稻内生真菌作用机制的最新研究成果,并对稻瘟病绿色防控新策略的未来发展方向进行了展望。Rice blast caused by Magnaporthe oryzae is a worldwide disease, which seriously affects the global rice production. The rapid variation of M. oryzae resulted in a decline in resistant variety screening and pesticide control. Therefore, revealing the pathogenic mechanism of M. oryzae at the molecular level can provide target molecules for rice disease control and new fungicide development. The utilization of endophytic fungi from wild rice to control rice blast provides a new idea for green management. By excavating the resources of wild rice endophytic fungi, identifying functional strains with the activities of promoting growth, immune induction and resistance to adverse conditions, and exploring the interaction mechanism between rice and endophytic fungi, it provides a basic theory for the development of endophytic fungi as new biocontrol agents. This review mainly summarized the novel research results on the pathogenic mechanism of M. oryzae and the functional mechanism of endophytic fungi in rice in recent years, and look forward to the future development direction of a new green prevention and control strategy for M. oryzae.
