摘要: UDP-glycosyltransferases (UGTs) are major phase II enzymes involved in the metabolic detoxification of xenobiotics. In this study, two UGT-inhibitors, 5-nitrouracil and sulfinpyrazone, significantly increased sulfoxaflor toxicity against sulfoxaflor-resistant (Sul-R) Aphis gossypii, whereas there were no synergistic effects in susceptible (Sus) A. gossypii. The activity of UGTs in the Sul-R strain was significantly higher (1.35-fold) than that in the Sus strain. Further, gene expression determination demonstrated that 11 of 23 UGT genes were significantly upregulated (1.40- to 5.46-fold) in the Sul-R strain, among which the expression levels of UGT350A2, UGT351A4, UGT350B2, UGT342C2, and UGT343C2 could be induced by sulfoxaflor. Additionally, knockdown of UGT350A2, UGT351A4, UGT350B2, and UGT343C2 using RNA interference (RNAi) significantly increased sensitivity (1.57- to 1.76-fold) to sulfoxaflor in the Sul-R strain. These results suggested that UGTs might be involved in sulfoxaflor resistance in A. gossypii. These findings will facilitate further work to validate the functional roles of these UGT genes in sulfoxaflor resistance.
