摘　　要：双生病毒科(Geminiviridae)菜豆金黄花叶病毒属病毒是一类重要的植物病毒,主要危害番茄、烟草、棉花等多种经济作物,自然条件下主要由介体昆虫烟粉虱Bemisia tabaci传播。菜豆金黄花叶病毒属病毒在田间的暴发受多种因素的影响,其中一个最重要的因素就是其介体昆虫烟粉虱。因此,明确烟粉虱在田间传播和扩散特定病毒中的作用及影响因素,对于解析病毒病流行的生物学基础具有重要意义。本文综述了烟粉虱对菜豆金黄花叶病毒属病毒的传播及影响因素,并讨论了病毒对媒介昆虫的适应及其机制。菜豆金黄花叶病毒属病毒和烟粉虱都为全球分布的有害生物,通过生物信息学的分析发现,两者都呈现地域相关的遗传多样性。而在生物学的研究中发现,烟粉虱隐存种往往对与其起源于同一地区的病毒具有较高的传播效率。这些发现为进一步解析烟粉虱对菜豆金黄花叶病毒属病毒的传播提供了重要的参考。Begomoviruses(Geminiviridae)are a group of important plant viruses that affect the production of many crops such as tomato,tobacco and cotton,and they are transmitted by the whitefly Bemisia tabaci under natural conditions.The outbreak of begomoviruses in the field is shaped by many factors,among which their whitefly vectors are one of the most significant.Therefore,determining the role of whitefly in the transmission and spread of certain begomoviruses is the key to deciphering the nature of plant diseases caused by begomoviruses.In this article,we discussed the factors affecting the transmission of begomoviruses and the mechanisms underlying the adaptation of viruses to their insect vectors.Both begomoviruses and whiteflies are pests with a cosmopolitan distribution,and bioinformatics-based analysis indicates that both exhibit geography-related genetic variation.Transmission assays showed that begomoviruses tend to be transmitted with higher efficiency by the whitefly species sharing the same geographic origin than the ones whose origins are different from those of the viruses.Information provided here offers an important source of references for further research with regard to the transmission of begomoviruses by whiteflies.
