摘要
The whitefly Bemisia tabaci is a notorious agricultural pest of many crops worldwide. Although it is thought that B. tabaci secretes saliva into the host plant to counter plant defenses, knowledge on the whitefly salivary proteome is limited. Here, we characterized the gene/protein repertoires of B. tabaci salivary glands and secreted saliva by transcriptomic and liquid chromatography tandem mass spectroscopy analyses. A total of 698 salivary gland-enriched unigenes and 171 salivary proteins were identified. Comparative analysis between the B. tabaci salivary proteins and those of different arthropod species revealed numerous similarities in proteins associated with binding, hydrolysis, and oxidation-reduction, which demonstrates a degree of conservation across herbivorous saliva. There were 74 proteins only identified in B. tabaci saliva, of which 34 were B. tabaci-specific. In addition, 13 salivary proteins, of which 11 were B. tabaci-specific, were differentially regulated when B. tabaci fed on different hosts. Our results provide a good resource for future functional studies of whitefly salivary effectors, and might be useful in pest management.
