Rice blast is a highly destructive crop disease that requires the interplay of three essential factors: the virulent blast fungus, the susceptible rice plant, and favorable environmental conditions. Although previous studies have focused mainly on the pathogen and rice, recent research has shed light on the molecular mechanisms by which the blast fungus and environmental conditions regulate host resistance and contribute to blast disease outbreaks. This review summarizes significant achievements in understanding the sophisticated modulation of blast resistance by Magnaporthe oryzae effectors and the dual regulatory mechanisms by which environmental conditions influence rice resistance and virulence of the blast fungus. Furthermore, it emphasizes potential strategies for developing blast-resistant rice varieties to effectively control blast disease.
稻瘟病是一种极具破坏性的作物病害，需要三种基本因素相互作用：致病力强的稻瘟病菌、感病的水稻植株以及适宜的环境条件。尽管先前的研究主要集中在病原菌和水稻上，但最近的研究揭示了稻瘟病菌和环境条件调节宿主抗性并导致稻瘟病爆发的分子机制。本综述总结了在理解稻瘟病菌效应子对稻瘟病抗性的复杂调控以及环境条件影响水稻抗性和稻瘟病菌毒力的双重调控机制方面取得的重大进展。此外，还强调了培育抗稻瘟病水稻品种以有效控制稻瘟病的潜在策略。
