摘要

Transcription factors (TFs), known as cysteine-rich polycomb-like proteins (CPP), are a small gene family that regulates plant growth, development, and stress response. Furthermore, recent research has demonstrated that a range of cytokines play a role in the control of the cell cycle, with the E2F/DP TF family serving as a key regulatory connection. However, little is known about the evolutionary and functional traits of the members of these gene families in plants. Numerous CPP and E2F/DP gene family members have been identified in various plant species. Nevertheless, no thorough phylogenetic study of Chenopodium quinoa CPP and E2F/DP has been published. In this study, 10 CqCPP and eight CqE2F/DP proteins in quinoa, based on Arabidopsis and rice proteins, were classified into two (A1 and B), and three groups (E2F, DP, and DEL), respectively. Moreover, homology analysis of CqCPPs and CqE2F/DPs between quinoa and other species such as Beta vulgaris, Spinacia oleracea, Amaranthus hypochondriacus, and Arabidopsis thaliana indicated that these gene families showed greater similarity in quinoa with both species of Beta vulgaris and Spinacia oleracea. Growth- and stress-related cis-acting elements were found in the upstream regions of CqCPPs, thus highlighting their significance for plant growth and abiotic stress tolerance. Ka/Ks levels showed that the majority of CqCPP and CqE2F/DP family members underwent purifying selection. Our findings suggest that these gene families in quinoa may be important for plant development and responses to environmental stressors. Together, these findings offer crucial data for understanding the biological roles of CPP and E2F/DP in quinoa breeding.
