The Calmodulin binding transcription activator (CAMTA) is a calmodulin binding transcription factor with a relatively conservative structure, which is widely existed in eukaryotes, and plays the key role for development and abiotic stress response. In this study, total seven ZmCAMTA (ZmCAMTA1-7) genes were identified in the maize genome by silico cloning method. The pattern expression of ZmCAMTA2-6 showed that increased mRNA levels were exhibited in roots and tassels. Various abiotic stress, such as heat, cold, and salt, were performed, and results displayed that, ZmCAMTA4 and ZmCAMTA6 genes showed accumulated mRNA level under cold treatment. We also analyze the physicochemical properties, system evolution and collinearity, gene structure of the encoded protein. The results showed that the gene family structure, motifs, and domains were relatively conserved. Collinearity analysis suggested the existence of genome-wide physicochemical properties, system evolution and collinearity, gene structure of the encoded protein polyploidy events in the evolution of ZmCAMTA genes.
