Superoxide dismutase (SOD) is an important antioxidant enzyme and widely exists in organisms. The whole genome scanning and bioinformatics analysis of millet superoxide dismutase (SOD) gene family were carried out by using bioinformatics method on the search platform of maize gene database. The results showed that the SOD gene family of maize contained 15 genes, which were unevenly distributed on 9 chromosomes. The amino acid sequence length of the protein ranged from 86 aa to 386 aa. Fifteen SOD proteins in maize contained 6 Cu-SOD motifs and 9 Mn-SOD motifs. Evolutionary tree analysis showed that SOD protein of maize was related to SOD protein sequence of millet and sorghum. The results of this study can provide some references for further understanding the SOD gene family and the antioxidant mechanism of maize.
