CAMTA gene family analysis in maize and expression of genes responsive to heat stress and germination

Calmodulin is a regulated protein of calcium and is a small intracellular protein that binds to calcium ions and mediates many of its intracellular actions. Calmodulin-binding transcription factors (CAMTAs) are recognized as one of the stress-responsive proteins. In this study, CAMTA genes were selected in maize. In this study, CAMTA family genes in maize were selected and chromosomal distribution, gene structure, domain patterns, and phylogenetic tree of CAMTA genes in maize were analyzed to further evaluate. To identify expression levels in different plant tissues, CAMTA gene expression analysis in response to heat stress and germination was studied. ZmCAMTA1 and ZmCAMTA2 genes were expressed in heat stress. Gene structure was similar in most proteins in each group, confirming the phylogenetic classification of CAMTA. Prediction of cis-elements in the promoter region of genes showed that bZIP and AP2 / ERF had the highest cis-elements in the promoter region of ZmCAMTA genes. In leaf tissue, ZmCAMTA1 gene was up-regulated expression in response to heat stress. ZmCAMTA2 gene was up-regulated in stem tissue in response to heat stress. The ZmCAMTA2 gene in response to increased expression germination showed that this study could be considered as a useful resource for future comparative studies of ZmCAMTA in different plant species and provide useful information for finding candidate genes in response to stress.
