摘　　要：植物病毒引发的病害严重制约农作物的产量和品质,在目前已报道的植物病毒中有约80%依赖媒介昆虫的传播.阐明虫媒病毒病害循环中病毒-植物-昆虫这三种跨界生物间互作的分子信号及分子机制,是更高效控制虫媒病毒病害的基础.病毒病害的流行范围和强度主要取决于病毒的侵染和传播这两个关键环节,得益于不断发展的分子生物学、细胞生物学和各种组学技术,植物病毒如何成功侵染寄主植物以及如何高效地通过媒介昆虫传播被不断解析.本文主要阐述了病毒逃逸植物免疫、突破媒介昆虫屏障和免疫、直接或间接地调控媒介昆虫传毒的具体机制,展现了虫媒病毒操控寄主植物和媒介昆虫促进病害流行中的强大能力,也揭示了虫媒病害防控中可供选择的分子靶标.Plant viral diseases seriously restrict the yield and quality of crops.About 80%of the reported plant viruses are transmitted by vector insects.Elucidating the molecular signals and mechanisms of the trans-kingdom interactions between viruses,plants,and vector insects in the disease cycle of arbovirus is the foundation for more efficient control of arboviral diseases.The epidemic scope and intensity of viral diseases mainly depend on the two key steps of virus infection and transmission.With the continuous development of molecular biology,cell biology and various omics technologies,how plant viruses successfully infect host plants and how they efficiently spread through vector insects are constantly analyzed.This article mainly elaborates on the specific mechanisms by which viruses escape plant immunity,break through vector insect barriers and immunity,and directly or indirectly regulate their transmissions by vector insects.It demonstrates the powerful ability of arboviruses to manipulate host plants and vector insects to promote disease epidemics,and also reveals the molecular targets available for the prevention and control of arboviral diseases.
