The outer layer of russet pear fruit skin is coated with suberin, a key protective barrier that deters pests and minimizes water loss, making it an important trait for fruit cultivation. This study investigates the mechanisms underlying russet formation in the pear exocarp, focusing on the ‘Dangshansuli’ with yellow-green skin and its russeted mutant ‘Dangshanjinsu’ through proteomic analysis. The results revealed numerous differentially expressed proteins associated with the phenylpropanoid biosynthesis pathway, suberin and wax synthesis pathways, and sesquiterpenoid and triterpenoid synthesis pathways. Specifically, six PbSQE genes, encoding squalene epoxidases involved in triterpenoid synthesis, showed distinct expression patterns in the exocarp of ‘Dangshansuli’ and ‘Dangshanjinsu’ during fruit development. Overexpression of PbSQE3 and PbSQE6 in transgenic Arabidopsis significantly increased triterpenoid compounds, including ursolic acid, oleanolic acid, α-amyrin, and β-amyrin. These findings highlight the roles of PbSQE3 and PbSQE6 in triterpenoid biosynthesis and suggest they contribute to the downregulation of suberin deposition in the russet pear exocarp.
