有氧代谢或对生物和非生物胁迫的反应会不断产生活性氧 (ROS)。 ROS不仅是有氧代谢的有毒副产物，而且还是参与植物生长和环境适应的信号分子。抗氧化剂可以通过清除ROS来保护细胞免受氧化损伤。因此，它们通过调节细胞氧化还原状态和修饰基因表达在优化细胞功能中发挥重要作用。本文旨在回顾最近的研究，强调氧化还原信号在建立和维持根瘤菌和豆类之间的共生中的作用。
Reactive Oxygen Species (ROS) are continuously produced as a result of aerobic metabolism or in response to biotic and abiotic stresses. ROS are not only toxic by-products of aerobic metabolism, but are also signaling molecules involved in plant growth and environmental adaptation. Antioxidants can protect the cell from oxidative damage by scavenging the ROS. Thus, they play an important role in optimizing cell function by regulating cellular redox state and modifying gene expression. This article aims to review recent studies highlighting the role of redox signals in establishing and maintaining symbiosis between rhizobia and legumes.
