CCT genes family is widely present in plants and play vital roles in plant growth and development. Bioinformation methods were used to identify the TaCCTgenes at genome-wide level, a total of 80 TaCCT genes were identified. The gene structure, phylogenetic relationship, cis-elements, chromosome location and expression patterns were analyzed. Results showed that 80 TaCCT genes were unevenly distributed on wheat chromosomes, and there were 28, 24, and 28 CCTgenes were distributed in A, B, and D sub-genomes respectively. Phylogenetic analysis showed that TaCCT genes could be divided into three sub-families, namely COL, CMF, and PRR, which were belonged to 13 sub-groups. Gene structure and conserved motif analysis found that the gene structure and conserved domains of the same subgroup were basically the same. Cis-acting element analysis found that a total of 16 kinds of cis-acting elements were identified in the promoter region of TaCCT genes. Gene duplication analysis showed that 60 gene pairs were formed by 64 TaCCT genes, indicated that duplication and expansion occurred during the process of evolution. Expression patterns analysis showed that the TaCCT genes were differentially expressed under different tissues and different stress conditions, indicating that the TaCCT genes played an important role in wheat growth and development, as well as in response to abiotic stress. These findings provide a theoretical basis for further research on wheat CCT genes.
