Genome-Wide Identification and Characterization of the Calmodulin-Binding Transcription Activators (CAMTA) Gene Family in <i>Brassica</i> U-Triangle Species and Its Potential Role in Response to Phytohormones and Abiotic Stresses.

ABSTRACT: Calmodulin-binding transcription activators (CAMTAs) are pivotal regulators decoding calcium signals, with crucial roles in plant development, hormone responses, and adaptation to abiotic stresses. Although extensive research has been conducted on CAMTAs in model plants such as Arabidopsis thaliana, a comprehensive genome-wide analysis of the CAMTA gene family across the economically important Brassica U-triangle species has not been performed. In this study, we systematically identified and characterized 64 CAMTA genes from the genomes of Brassica U-triangle species. Phylogenetic analysis classified these genes into four conserved groups, a finding corroborated by analyses of gene structure and conserved motifs. These analyses revealed strong evolutionary preservation
