Genome-Wide Characterization and Expression Analysis of the Cysteine-Rich Polycomb-like Protein Gene Family in Response to Hormone Signaling in Apple (<i>Malus domestica</i>).

ABSTRACT: Cysteine-rich polycomb-like protein (CPP) transcription factors play critical roles in plant growth, development, and responses to stresses and hormone signaling. However, the research on the CPP gene family remains unexplored in apple. In this study, a total of 10 CPP genes (MdCPP1-MdCPP10) were identified and unevenly distributed across seven scaffolds. Phylogenetic and conserved motif analyses revealed that these 10 CXC domain-containing MdCPPs could be classified into three subfamilies. Evolutionary tree and synteny analyses demonstrated that apple shared the highest number of orthologous gene pairs with white pear compared to Arabidopsis. By analyzing the MdCPP gene promoter, a large number of cis-acting elements related to hormone and
