Genome-Wide Analysis of the Transcription Factor Gene Family in Pepper ( L.).

TCP transcription factors play a key role in regulating various developmental processes, particularly in shoot branching, flower development, and leaf development, and these factors are exclusively found in plants. However, comprehensive studies investigating TCP transcription factors in pepper ( L.) are lacking. In this study, we identified 27 members in the pepper genome, which were classified into Class I and Class II through phylogenetic analysis. The motif analysis revealed that in the same class exhibit similar numbers and distributions of motifs. We predicted that 37 previously reported miRNAs target 19 . The expression levels of varied in various tissues and growth stages. Specifically, , a member of Class II (CIN), exhibited significantly high expression in flowers. Class I exhibited high expression levels in leaves, while Class II showed high expression in lateral branches, especially in the CYC/TB1 subclass. The expression profile suggests that play specific roles in the developmental processes of pepper. We provide a theoretical basis that will assist in further functional validation of the .
