摘　　要：在病毒与宿主的长期相互作用中,部分病毒基因序列可以被整合到宿主基因组中,形成内源性病毒元件(endogenous viral element,EVE)。随着近年来基因组学和宏病毒组学的发展,研究人员发现除逆转录病毒外,非逆转录RNA病毒同样可以被整合到传毒媒介等真核生物基因组中,形成内源性非逆转录RNA病毒元件(non-retroviral EVE,nrEVE),但关于其具体功能的研究较少。鉴于传毒媒介传播的动物病毒和植物病毒对人、动物及植物造成严重危害,该文聚焦近年来国内外关于传毒媒介基因组中的EVE,特别是nrEVE的研究,总结了EVE的定义及发现,蚊子、蚜虫、蓟马、飞虱和蜱虫等重要传毒媒介中EVE的多样性及功能,并对该领域的后续研究重点进行展望,以期为揭示RNA病毒与宿主的长期协同进化关系及发展新的抗虫策略提供理论基础。During the long-term interaction between viruses and their hosts,certain viral sequences can be integrated into the host genomes,forming endogenous viral elements(EVEs).In addition to retroviruses,recent advances in genomics and viromics have unveiled the presence of non-retroviral endogenous RNA viral elements(nrEVEs)within eukaryotic genomes.Nevertheless,the functions of these identified EVEs or nrEVEs are poorly understood.Given the significant implications of vectortransmitted animal and plant viruses to public health for humans,animals,and plants,this review concentrates on recent progress in research regarding EVEs,particularly nrEVEs,in the genomes of virustransmitting vectors.This review summarizes the definition and discovery of EVE,diversity and functions of EVEs in important vectors,including mosquitoes,aphids,thrips,planthoppers,and ticks.Furthermore,this review also provides overview on future research in this field,which will contribute to revealing the long-term co-evolutionary relationship between RNA viruses and their hosts,and to developing new pest control strategies.
