Abstract：Glutathione S-transferases(GST),the important detoxification enzymes in insects,play an important role in insect growth and development,host utilization and environmental adaptation.Based on Transcriptome data,this researches screened and identified the gene members of the GST family in the peach borer,Conogethes punctiferalis.Further,GST family genes in C.punctiferalis were analyzed in physical and chemical properties,conservative motifs,subcellular localization,phylogenetic tree,etc.The expression level of GST family genes was also studied based on transcriptome data of the peach borer feeding on different host plants.The results showed that 16 GST genes were identified from the peach borer,and the predicted number of amino acids in the coding protein was 104～285,all of which were hydrophilic proteins.The phylogenetic tree indicates that the GST family genes of the peach borer be divided into six types,and the same type of genes generally have similar conserved motifs.After feeding on different plants,GST genes of the peach moth borer were all expressed,and the expression levels of different GST genes varied significantly on different host plants.The research results lay a foundation for in-depth research on the physiological functions of GST in C.punctiferalis.
