植物和病毒在自然生态系统中长期共存，相互作用，甚至共同进化，维持着植物抗病和病毒致病之间的动态平衡。在病毒与寄主的相互作用过程中，植物往往表现出异常的生长发育。然而，植物并不是被动地抵抗病毒的攻击，而是进化出了复杂而有效的防御机制来抵抗、限制或破坏病毒感染。人们普遍认为，感染的初始阶段是病毒与宿主之间相互作用最强烈的阶段，也是激活信号转导途径种类最多的阶段。本文综述了水稻抗病毒研究的最新成果，并讨论了水稻抗病毒的各种分子机制，包括基于R基因和隐性抗性的机制、RNA沉默、植物激素信号转导、自噬和WUS介导的抗病毒免疫。最后，我们讨论了水稻抗病毒育种面临的挑战和前景。
Plants and viruses coexist in the natural ecosystem for extended periods of time, interacting with each other and even coevolving, maintaining a dynamic balance between plant disease resistance and virus pathogenicity. During virus–host interactions, plants often exhibit abnormal growth and development. However, plants do not passively withstand virus attacks but have evolved sophisticated and effective defense mechanisms to resist, limit, or undermine virus infections. It is widely believed that the initial stage of infection features the most intense interactions between the virus and the host and the greatest variety of activated signal transduction pathways. This review describes the most recent findings in rice antiviral research and discusses a variety of rice antiviral molecular mechanisms, including those based onRgenes and recessive resistance, RNA silencing, phytohormone signaling, autophagy and WUS-mediated antiviral immunity. Finally, we discuss the challenges and future prospects of breeding rice for enhanced virus resistance.
