Abstract

The TEOSINTE-BRANCHED1/CYCLOIDEA/PROLIFERATING-CELL-FACTOR (TCP) gene family, a plant-specific transcription factor family, plays pivotal roles in various processes such as plant growth and development regulation, hormone crosstalk, and stress responses. However, a comprehensive genome-wide identification and characterization of the TCP gene family in peanut has yet to be fully elucidated. In this study, we conducted a genome-wide search and identified 51 TCP genes (designated as AhTCPs) in peanut, unevenly distributed across 17 chromosomes. These AhTCPs were phylogenetically classified into three subclasses: PCF, CIN, and CYC/TB1. Gene structure analysis of the AhTCPs revealed that most AhTCPs within the same subclade exhibited conserved motifs and domains, as well as similar gene structures. Cis-acting element analysis demonstrated that the AhTCP genes harbored numerous cis-acting elements associated with stress response, plant growth and development, plant hormone response, and light response. Intraspecific collinearity analysis unveiled significant collinear relationships among 32 pairs of these genes. Further collinear evolutionary analysis found that peanuts share 30 pairs, 24 pairs, 33 pairs, and 100 pairs of homologous genes with A. duranensis, A. ipaensis, Arabidopsis thaliana, and Glycine max, respectively. Moreover, we conducted a thorough analysis of the transcriptome expression profiles in peanuts across various tissues, under different hormone treatment conditions, in response to low- and high-calcium treatments, and under low-temperature and drought stress scenarios. The qRT-PCR results were in accordance with the transcriptome expression data. Collectively, these studies have established a solid theoretical foundation for further exploring the biological functions of the TCP gene family in peanuts, providing valuable insights into the regulatory mechanisms of plant growth, development, and stress responses.
