Reactive oxygen species (ROS) serve as crucial signaling molecules that facilitate the interactions between plants and environmental stimuli, thereby influencing a wide range of physiological and biochemical processes, such as vegetative apex development and organ morphogenesis. In response to environmental stresses, plants enhance ROS production to initiate a robust protective response. To manage excessive ROS levels, plants have developed a sophisticated antioxidative defense system comprising both enzymatic and non-enzymatic components, which work synergistically to scavenge ROS and alleviate ROS-induced deleterious effects on biomolecules. This review provides a comprehensive overview of ROS metabolism, signaling transduction pathways, and their implications for the oxidative modification of nucleic acids, lipids, and proteins within plant cells.
活性氧（ROS）作为关键的信号分子，促进植物与环境刺激之间的相互作用，从而影响广泛的生理和生化过程，如营养顶端发育和器官形态发生。响应环境胁迫时，植物增强ROS的产生以启动强大的保护反应。为了控制过量的ROS水平，植物已发展出一套复杂的抗氧化防御系统，该系统由酶促和非酶促成分组成，它们协同作用以清除ROS并减轻ROS对生物分子的有害影响。本综述全面概述了ROS代谢、信号转导途径及其对植物细胞内核酸、脂质和蛋白质氧化修饰的影响。
