Cytokinin dehydrogenase (CKX; EC.1.5.99.12) regulates the level of cytokinin (CK) in
plants and is involved in CK regulatory activities. In different plants, a small gene family
encodes CKX proteins with varied numbers of members. These genes are expanded in the
genome mainly due to segmental duplication events. Despite their biological importance,
CKX genes in Triticum aestivum have yet to be studied in depth. A total of 11 CKX
subfamilies were identified with similar gene structures, motifs, domains, cis-acting
elements, and an average signal peptide of 25 amino acid length was found. Introns,
ranging from one to four, were present in the coding regions at a similar interval in major
CKX genes. Putative cis-elements such as abscisic acid, auxin, salicylic acid, and lowtemperature-,
drought-, and light-responsive cis-regulatory elements were found in the
promoter region of majority CKX genes. Variation in the expression pattern of CKX genes
were identified across different tissues in Triticum. Phylogenetic analysis shows that the
same subfamily of CKX clustered into a similar clade that reflects their evolutionary
relationship. We performed a genome-wide identification of CKX family members in the
Triticum aestivum genome to get their chromosomal location, gene structure, cis-element,
phylogeny, synteny, and tissue- and stage-specific expression along with gene ontology.
This study has also elaborately described the tissue- and stage-specific expression and is
the resource for further analysis of CKX in the regulation of biotic and abiotic stress
resistance, growth, and development in Triticum and other cereals to endeavor for higher
production and proper management.
