iTRAQ-based proteomic analysis of resistant Nicotiana tabacum in response to Bemisia tabaci infestation
Arthropod-Plant Interactions 13 (3), 505-516
Abstract: Bemisia tabaci is a pest that poses a significant threat to the survival of Nicotiana tabacum and leads to decreased production and economic losses. However, it is still unknown whether proteomic changes occur in resistant N. tabacum in response to B. tabaci stresses. In the present study, iTRAQ was performed to unmask the regulating networks mediated by candidate proteins involved in resistance against B. tabaci. A total of 357 differentially accumulated proteins (DAPs) responsible for B. tabaci infestation were identified, including 178 upregulated and 179 downregulated proteins. The majority of DAPs were involved in the regulation of ROS production, cell expansion, citrate cycle (TCA cycle), photosynthesis, carbon fixation, and metabolic pathways. Moreover, the expression patterns of several genes encoding DAPs were validated by qRT-PCR. Our results indicate these proteins play a significant role in the resistance of N. tabacum against B. tabaci infestation. These findings also provide a valuable proteomic resource for the elucidation of the mechanism of resistance against B. tabaci.
