虫媒水稻病毒病在许多水稻种植国广泛流行，具有重要的经济意义。水稻病毒与其昆虫媒介之间的长期关联导致进化权衡，维持病毒感染昆虫的适应性成本与病毒通过昆虫的持续传播之间的平衡。为了促进最佳复制，水稻病毒激活天然免疫应答，如自噬、凋亡和载体中的应激调节信号通路;同时，激活保守的昆虫小干扰RNA抗病毒通路以控制病毒的过度复制，保证病毒的持续传播。此外，越来越多的证据表明，水稻病毒可以直接操纵它们的载体，或者通过诱导宿主植物的变化来促进病毒病原体的传播。因此，了解植物-病毒-昆虫的关系提供了重要的见解，疾病流行病是如何发生的，并促进了强大的疾病控制新策略的设计。
Insect-borne rice viral diseases are widespread and economically important in many rice-growing countries. Longterm associations between rice viruses and their insect vectors result in evolutionary trade-offs that maintain a balance between the fitness cost of the viral infection of insects and the persistent transmission of the virus by the insect. To promote optimal replication, rice viruses activate innate immune responses, such as autophagy, apoptosis, and stress regulated signaling pathways in the vector; meanwhile, a conserved insect small interfering RNA antiviral pathway is activated to control excessive viral replication, guaranteeing persistent virus transmission. Furthermore, growing evidence has shown that rice viruses can manipulate their vectors either directly or by inducing changes in host plants to promote the spread of viral pathogens. Thus, understanding the plant-virus-insect relationships offers important insights into how disease epidemics occur and facilitates the design of powerful new strategies for disease control.
