Reactive oxygen species (ROS) are small molecules with high oxidative activity, and are usually produced as byproducts of metabolic processes in organisms. ROS play an important role during the interaction between plant hosts and pathogenic fungi. Phytopathogenic fungi have evolved sophisticated ROS producing and scavenging systems to achieve redox homeostasis. Emerging evidences suggest that ROS derived from fungi are involved in various important aspects of the development and pathogenesis, including formation of conidia, sclerotia, conidial anastomosis tubes (CATs) and infectious structures. In this mini-review, we summarize the research progress on the redox homeostasis systems, the versatile functions of ROS in the development and pathogenesis of phytopathogenic fungi, and the regulation effects of exogenous factors on intercellular ROS and virulence of the fungal pathogens.
活性氧（ROS）是具有高氧化活性的小分子，通常作为生物体代谢过程的副产物产生。ROS在植物宿主与致病真菌的相互作用中发挥重要作用。植物病原真菌已经进化出复杂的ROS产生和清除系统以实现氧化还原稳态。新出现的证据表明，真菌来源的ROS参与了发育和发病机制的各个重要方面，包括分生孢子、菌核、分生孢子吻合管（CATs）和侵染结构的形成。在本综述中，我们总结了氧化还原稳态系统的研究进展、ROS在植物病原真菌发育和发病机制中的多种功能，以及外源因素对真菌病原体细胞间ROS和毒力的调节作用。
