Abstract Superoxide dismutase (SOD) gene family plays an important role in the development and stress response in potato (Solanum tuberosum). However, there are few reports on the identification of SOD gene family members in potato and their gene expression change after tuber damage. In order to analyze the bioinformatics characteristics of potato SOD family members, investigate the expression difference of each family member in different organs of potato seedlings and response in damaged tubers, the softwares GSDS 2.0 and PLACE were used to analyze gene structure and cis-element of StSODs, and the softwares ProtParam, ProtComp 9.0, MEGA7.0, and MEME 4.11.1 were used to analyze physical and chemical properties, subcellular localization, phylogenetic relationship and conserved motifs. The expression level of the gene family numbers was determined in different organs and artificial wounded tuber by qRT-PCR. SOD activity and O2• - and H2O2 contents were analyzed at wounded sites of tubers with 10 mmol/L diethyldithiocarbamate (DDC) treatment by biochemical methods. The results showed that 8 StSODs were identified from the potato genome with different domains such as Cu/ZnSOD domain, Fe/MnSOD α-hairpin domain and C-terminal Fe/MnSOD domain. The amino acid lengths of these StSODs were 152~312 with isoelectric point 5.28~7.13. The predicted subcellular localizations were in the cytoplasm, chloroplast and mitochondria. The StSODs were distributed on 6 of 12 chromosomes unevenly, and divided into 3 subgroups Cu/ZnSOD, FeSOD, and MnSOD, phylogenetically based on their different domains. The promoters of StSODs contained a large number of cis-elements responding to lights, stresses and hormones. StSODs expressed in the roots, stems, leaves, buds and tubers of potato seedling, the expression levels of StCSD1 and StCSD2 in the tuber were significantly higher than that of other organs. The expression of StSODs could be induced at wounded sites of wounded tubers. The expression of StFSD1 and StFSD2 were significantly induced in the early stage, the increased expression of StCSD3 was observed both in early and late stages, while rest SOD genes were expressed in mid stage of the damage. DDC treatment significantly decreased SOD activity and H2O2 content, but increased O2• - content. The present study could provide a reference for further functional study of StSODs in wounded tubers.
