摘要： BACKGROUNDTomato chlorosis virus (ToCV) is an RNA virus that seriously reduces tomato yield, mainly transmitted by whiteflies (Bemisia tabaci) in a semi-persistent manner. Currently, preventing ToCV transmission by selecting the target gene of whiteflies is an effective measure to control ToCV. Proteomic analysis revealed that 14-3-3 protein levels significantly increase in ToCV-infected B. tabaci. To verify the target role of 14-3-3 protein, its gene expression was down-regulated with RNA interference (RNAi) technology to explore its function in ToCV acquisition and transmission, and to find a new strategy for controlling ToCV transmission by whiteflies.RESULTSThe amount of ToCV was positively correlated with the expression of Bt14-3-3 epsilon and Bt14-3-3 zeta in B. tabaci, and ToCV promotes glycogen synthesis via the phosphoinositide-3-kinase/protein kinase B pathway (PI3K/AKT pathway). After silencing Bt14-3-3 epsilon and Bt14-3-3 zeta, ToCV acquisition, transmission, oviposition and sugar metabolism of B. tabaci were suppressed.CONCLUSIONSThese results illustrated that ToCV induced Bt14-3-3 epsilon and Bt14-3-3 zeta, and promoted glycogen synthesis via PI3K/AKT pathway in B. tabaci. Silencing 14-3-3 genes prevented ToCV acquisition, ToCV transmission, oviposition and sugar metabolism of B. tabaci. It could provide a basis for establishing a new strategy to regulate ToCV transmission of B. tabaci by using 14-3-3 protein. (c) 2025 Society of Chemical Industry.
