摘　　要：稻瘟病是危害世界水稻生产最严重的真菌病害之一。稻瘟病菌生理小种变异快,水稻品种的抗性一般仅能维持3~5年。培育和种植抗性品种是目前最经济有效的措施。近年来,对稻瘟病菌致病机制和抗性基因分子机理的系统研究,加深了对该病原菌-宿主系统中病原相关分子模式诱导的免疫反应机制和病原菌效应蛋白诱导的免疫反应机制的了解。本文综述了水稻抗稻瘟病的两种天然免疫机制研究的最新进展,并对目前水稻抗稻瘟病分子机制研究中急需解决的问题和挑战进行探讨和展望。Rice blast disease, caused by Magnaporthe oryzae, threatens global food security. Owning to the rapid evolution of M. oryzae isolates, resistant cultivars always become susceptible in 3-5 years. Breeding and planting durable resistant cultivars is the most effective method. Recent advances in understanding the pathogenesis of M. oryzae and rice resistance mechanisms led to a deeper understanding of PAMPs-and effector-triggered immunity in this pathosystem. This review summarizes the recent progresses for PTI, the cloned rice blast R genes, cloned Avr genes of M. oryzae and the interaction between them. We also discussed some of the major unanswered questions for this pathosystem and the opportunities for future investigations.
