Comparative transcriptome analysis reveals networks of genes activated in the whitefly, Bemisia tabaci when fed on tomato plants infected with Tomato yellow leaf curl virus
Abstract 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. Highlights First whitefly transcriptome in response to feeding on TYLCV-infected plants. Gene expression patterns were similar when fed on TYLCV or ToCV infected tomato. Cathepsin in TYLCV-whitefly was similar to that in aphid transmitting a luteovirus. Hemocyanin identified in whitefly may have a similar function in psyllids. Genes involved in feeding behavior were also identified in whitefly fed on TYLCV. Graphical abstract [DISPLAY OMISSION]
