中文摘要：

烟粉虱以持久性、可循回的方式传播双生病毒。烟粉虱传毒历经获毒、持毒和传毒3个阶段,烟粉虱体内的病毒受体、病毒蛋白以及寄主植物因子都参与了这个过程。本文综述了影响烟粉虱特异性传播双生病毒的因素以及二者的直接和间接互作。烟粉虱传播双生病毒的特异性不仅与烟粉虱隐种和病毒种类有关,还与烟粉虱体内特定的器官或细胞、烟粉虱和病毒的蛋白以及烟粉虱体内的共生细菌有关。在烟粉虱和双生病毒的长期共进化中,病毒可以通过调控烟粉虱和寄主植物的特性而促进其自身的传播。

英文摘要：

Geminiviruses are transmitted by the whitefly Bemisia tabaci in a persistent,circulative manner. Successful transmission of the virus from host to host requires three crucial steps： virus acquisition,retention and transmission. Many factors are involved in this process,including certain proteins from the vectors（ e. g.,receptors of the virus）,viral proteins and host plant factors. In this article,we reviewed the factors that affect the transmission specificities of geminiviruses by whiteflies as well as direct and indirect interactions between whiteflies and geminiviruses. The transmission efficiency of geminivirus depends on a number of variables,e. g.,the species of whiteflies and viruses involved,specific organs or cells of whitefly,whitefly and viral proteins,and hidden players like endosymbionts.The long-term association of the virus with the whiteflies and its host plants renders the virus the potential to alter the characteristics of its vector and host to facilitate its transmission.
