description The <i>CPP</i> gene family comprises transcription factor genes containing a conserved CRC domain, which is mainly involved in plant development and evolution. Although <i>CPP</i> genes have been widely studied in many plants, little is known about them in woody plants, especially in the endangered species <i>Phoebe bournei</i> (Hemsl.). In the genome of <i>Phoebe bournei,</i> we identified 11 <i>PbCPP</i> genes (<i>PbCPP1</i>-<i>PbCPP11</i>) distributed on four chromosomes, with large differences in the number of amino acids. They encode both acidic and alkaline proteins. A phylogenetic analysis showed that these <i>PbCPP</i> genes can be divided into three subfamilies, A, B, and C, which contain seven, two, and two genes, respectively. Through an interspecific collinearity analysis, we identified homologous <i>PbCPP</i> genes. A promoter cis-acting element analysis revealed that PbCPPs contain a variety of elements that respond to plant hormones, stress signals, and light and play a role in growth and development, and most <i>PbCPP</i> genes (except <i>PbCPP3</i> and <i>PbCPP8</i>) contain MYB binding site elements that regulate drought-induced stress responses, indicating that they play an important role in plant drought resistance. An expression analysis showed that <i>PbCPP3</i> and <i>PbCPP4</i> expression was high in the roots and stems and lower in the leaves, whereas the expression of most of the other genes was low in the roots, stems, and leaves. In addition, six representative <i>PbCPP</i> genes were detected using qRT-PCR. The results show significant differences in the expression of <i>PbCPP</i> genes under abiotic stress conditions (drought, cold, and salt), indicating that they play an important role in stress responses. This study preliminarily verified the role of the <i>PbCPP</i> gene family in different abiotic stress responses, which is of great significance for understanding its mechanism in plant growth and development and stress adaptation.
