Animals and plants evolved sophisticated mechanisms that regulate their responses to mechanical injury. Wound response in animals mainly promotes wound healing processes, nerve cell regeneration, and immune system responses at the vicinity of the wound site. In contrast, wound response in plants is primarily directed at sealing the wound site via deposition of various compounds and generating systemic signals that activate multiple defense mechanisms in remote tissues. Despite these differences between animals and plants, recent studies have shown that reactive oxygen species (ROS) play very common signaling and coordination roles in the wound responses of both systems. This review provides an update on recent findings related to ROS-regulated coordination of intercellular communications and signal transduction during wound response in plants and animals. In particular, differences and similarities in H2O2-dependent long-distance signaling between zebrafish and Arabidopsis thaliana are discussed.
动植物进化出了精细的机制来调节它们对机械损伤的反应。动物的伤口反应主要促进伤口愈合过程、神经细胞再生和伤口附近的免疫系统反应。相比之下，植物的伤口反应主要通过沉积各种化合物和产生系统信号来封闭伤口部位，激活远程组织中的多种防御机制。尽管动物和植物之间存在这些差异，但最近的研究表明，活性氧（ROS）在这两个系统的伤口反应中起着非常常见的信号转导和协调作用。本综述提供了有关 ROS 调节植物和动物伤口反应中细胞间通讯和信号转导的最新发现的更新。特别是，讨论了斑马鱼和拟南芥中 H2O2 依赖性长距离信号传递的差异和相似性。
