Reactive oxygen species (ROS) play a complex role in interactions between plant viruses and their host plants. They can both help the plant defend against viral infection and support viral infection and spread. This review explores the various roles of ROS in plant-virus interactions, focusing on their involvement in symptom development and the activation of plant defense mechanisms. The article discusses how ROS can directly inhibit viral infection, as well as how they can regulate antiviral mechanisms through various pathways involving miRNAs, virus-derived small interfering RNAs, viral proteins, and host proteins. Additionally, it examines how ROS can enhance plant resistance by interacting with hormonal pathways and external substances. The review also considers how ROS might promote viral infection and transmission, emphasizing their intricate role in plant-virus dynamics. These insights offer valuable guidance for future research, such as exploring the manipulation of ROS-related gene expression through genetic engineering, developing biopesticides, and adjusting environmental conditions to improve plant resistance to viruses. This framework can advance research in plant disease resistance, agricultural practices, and disease control.
活性氧（ROS）在植物病毒与其宿主植物的相互作用中扮演着复杂的角色。它们既能帮助植物抵御病毒感染，又能支持病毒的感染和传播。本综述探讨了 ROS 在植物-病毒相互作用中的各种作用，重点关注它们在症状发展和植物防御机制激活中的参与。文章讨论了 ROS 如何直接抑制病毒感染，以及它们如何通过涉及 miRNA、病毒衍生的小干扰 RNA、病毒蛋白和宿主蛋白的各种途径来调节抗病毒机制。此外，还研究了 ROS 如何通过与激素途径和外部物质相互作用来增强植物的抗性。该综述还考虑了 ROS 如何促进病毒的感染和传播，强调了它们在植物-病毒动态中的复杂作用。这些见解为未来的研究提供了有价值的指导，例如通过基因工程探索 ROS 相关基因表达的操纵、开发生物农药以及调整环境条件以提高植物对病毒的抗性。这一框架可以推动植物抗病性、农业实践和疾病控制方面的研究。
