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。活性氧在植物寄主与病原真菌的相互作用中起着重要的作用。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。新的证据表明，来自真菌的ROS参与了发育和致病的各个重要方面，包括分生孢子、菌核、分生孢子吻合管（CAT）和感染结构的形成。本文综述了植物病原真菌的氧化还原稳态系统、活性氧在植物病原真菌发育和致病中的作用以及外源因子对植物病原真菌细胞内活性氧和致病力的调控作用等方面的研究进展。
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.
