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 .
TCP转录因子在调控各种发育过程中起着关键作用，尤其是在枝条分枝、花发育和叶发育方面，并且这些因子仅在植物中发现。然而，缺乏对辣椒（L.）中TCP转录因子的全面研究。在本研究中，我们在辣椒基因组中鉴定出27个成员，通过系统发育分析将它们分为I类和II类。基序分析表明，同一类中的基序数量和分布相似。我们预测37个先前报道的miRNA靶向19个。在不同组织和生长阶段，的表达水平有所不同。具体而言，II类（CIN）的一个成员在花中表现出显著高表达。I类在叶中表现出高表达水平，而II类在侧枝中表现出高表达，特别是在CYC/TB1亚类中。表达谱表明在辣椒的发育过程中发挥特定作用。我们提供了一个理论基础，将有助于进一步对进行功能验证。
