The whitefly Bemisia tabaci can transmit hundreds of viruses to numerous agricultural crops in the world. Five genera of viruses, including Begomovirus and Crinivirus, are transmitted by B. tabaci. There is little knowledge about the genes involved in virus acquisition and transmission by whiteflies. Using a comparative transcriptomics approach, we evaluated the gene expression profiles of whiteflies (B. tabaci MEAM1) after feeding on tomato infected by a begomovirus, Tomato yellow leaf curl virus (TYLCV), in comparison to a recent study, in which whiteflies were fed on tomato infected by the crinivirus, Tomato chlorosis virus (ToCV). The data revealed similar temporal trends in gene expression, but large differences in the number of whitefly genes when fed on TYLCV or ToCV-infected tomato. Transcription factors, cathepsins, receptors, and a hemocyanin gene, which is implicated in mediating antiviral immune responses in other insects and possibly virus transmission, were some of the genes identified.

烟粉虱烟粉虱可将数百种病毒传播到世界各地的许多农作物中。五个属的病毒，包括菜豆金色花叶病毒和Crinivirus，被传输烟粉虱。关于粉虱获取和传播病毒的基因知之甚少。使用比较转录组学方法，与最近的一项研究（其中粉虱被喂食）相比，我们评估了粉虱（B. tabaci MEAM1）的基因表达谱，该粉虱摄食了被begomovirus番茄黄叶卷曲病毒（TYLCV）感染的番茄。感染了criinivirus，chlorochlorosissis病毒的番茄（ToCV）。数据显示，基因表达具有类似的时间趋势，但以TYLCV或ToCV感染的番茄为食时，粉虱基因的数量差异很大。鉴定出一些基因，其中转录因子，组织蛋白酶，受体和血蓝蛋白基因与介导其他昆虫的抗病毒免疫反应以及可能的病毒传播有关。
