Comprehensive Analysis of Sorghum CNGC Genes Reveals Their Potential Roles in Abiotic Stress Responses.

ABSTRACT: Background/Objectives: Cyclic nucleotide-gated channel (CNGC) genes play crucial roles in plant growth, development, and stress responses, yet their functions in sorghum remain poorly understood. Methods: This study systematically analyzed sorghum CNGC genes through genome-wide identification, encompassing chromosomal mapping, phylogenetic relationships, gene structure, cis-acting elements, miRNA regulation, and GO/KEGG annotation. Results: A total of 23 sorghum CNGC genes were identified and classified into five subclasses (I-IV-b), exhibiting high evolutionary conservation with rice and maize. Promoter and miRNA analyses revealed multi-level regulation involving light, hormones (ABA, JA), and stress response elements. Several SbCNGC genes were predicted to be regulat
