Pathogen recognition is linked to the perception of microbe/pathogen-associated molecular patterns triggering a specific and transient accumulation of reactive oxygen species (ROS) at the pathogen attack site. The apoplastic oxidative "burst" generated at the pathogen attack site depends on the ROS-generator systems including enzymes such as plasma membrane NADP (H) oxidases, cell wall peroxidases and lipoxygenase. ROS are cytotoxic molecules that inhibit invading pathogens or signalling molecules that control the local and systemic induction of defence genes. Post-translational modifications induced by ROS are considered as a potential signalling mechanism that can modify protein structure and/or function, localisation and cellular stability. Thus, this review focuses on how ROS are essential molecules regulating the function of proteins involved in the plant response to a pathogen attack through post-translational modifications.
病原体识别与微生物/病原体相关分子模式的感知有关，这些模式触发病原体攻击部位特定且短暂的活性氧 (ROS) 积累。病原体攻击部位产生的质外体氧化“爆发”取决于 ROS 生成系统，包括酶如质膜 NADP（H）氧化酶、细胞壁过氧化物酶和脂氧合酶。ROS 是细胞毒性分子，可抑制入侵的病原体或信号分子，从而控制局部和系统防御基因的诱导。ROS 诱导的翻译后修饰被认为是一种潜在的信号机制，可改变蛋白质结构和/或功能、定位和细胞稳定性。因此，本综述重点介绍 ROS 如何通过翻译后修饰作为调节参与植物对病原体攻击反应的蛋白质功能的必需分子。
