Weighted gene co-expression network analysis (WGCNA) of DEGs identified from ‘Meirensu’ pear peel after bag removal. (a) Hierarchical cluster tree showing 17 modules of co-expressed genes. Each of the 8,870 DEGs is represented by a tree leaf and each of the modules by a major tree branch. The lower panel shows modules in designated colours. (b) Module–trait correlations and corresponding p-values (in parentheses). The left panel shows the 17 modules and the number of member genes. The colour scale on the right shows module–trait correlations from −1 (blue) to 1 (red). The left panel “Anthocyanin” represents anthocyanin biosynthesis as a trait. The middle panel “UFGT2” represents the expression changes of PpUFGT2, which encodes the enzyme that catalyses the last step in anthocyanin biosynthesis, as a trait. The right panel “MYB10” represents the expression changes of PpMYB10, which is the key transcriptional factor activating anthocyanin biosynthesis, as a trait. (c) Cytoscape representation of co-expressed genes with edge weights ≥0.40 in module ‘blue’ and ‘midnight blue’. (d) RNA-Seq expression patterns of PpGST, Pp UFGT2 and PpMYB10.
