Reactive oxygen species (ROS) are signaling molecules that regulate many biological processes in plants. However, excess ROS induced by biotic and abiotic stresses can destroy biological macromolecules and cause oxidative damage to plants. As the global environment continues to deteriorate, plants inevitably experience abiotic stress. Therefore, in-depth exploration of ROS metabolism and an improved understanding of its regulatory mechanisms are of great importance for regulating cultivated plant growth and developing cultivars that are resilient to abiotic stresses. This review presents current research on the generation and scavenging of ROS in plants and summarizes recent progress in elucidating transcription factor-mediated regulation of ROS metabolism. Most importantly, the effects of applying exogenous substances on ROS metabolism and the potential regulatory mechanisms at play under abiotic stress are summarized. Given the important role of ROS in plants and other organisms, our findings provide insights for optimizing cultivation patterns and for improving plant stress tolerance and growth regulation.
活性氧（ROS）是调节植物许多生物学过程的信号分子。然而，生物和非生物胁迫诱导产生的过量ROS会破坏生物大分子，并对植物造成氧化损伤。随着全球环境持续恶化，植物不可避免地会遭遇非生物胁迫。因此，深入探索ROS代谢并更好地理解其调控机制对于调节栽培植物生长以及培育抗非生物胁迫的品种至关重要。本文综述了目前关于植物中ROS产生和清除的研究，并总结了在阐明转录因子介导的ROS代谢调控方面的最新进展。最重要的是，总结了施用外源物质对ROS代谢的影响以及非生物胁迫下潜在的调控机制。鉴于ROS在植物和其他生物体中的重要作用，我们的研究结果为优化栽培模式、提高植物抗逆性和生长调控提供了思路。
