Comprehensive Genome-Wide Identification and Expression Profiling of bHLH Transcription Factors in Areca catechu Under Abiotic Stress.

ABSTRACT: The basic helix-loop-helix (bHLH) transcription factor (TF) family, the second-largest among eukaryotes, is known for its evolutionary and functional diversity across plant species. However, bHLH genes have not yet been characterized in Areca catechu. In this study, we identified 76 AcbHLH genes, which exhibit a variety of physicochemical properties. Phylogenetic analysis revealed evolutionary relationships between Arabidopsis thaliana bHLH genes (AtbHLH) and their counterparts in A. catechu (AcbHLH). These analyses also highlighted conserved amino acid motifs (S, R, K, P, L, A, G, and D), conserved domains, and evolutionary changes, such as insertions, deletions, and exon gains or losses. Promoter analysis of AcbHLH genes reve
