From: Uncovering co-expression gene network modules regulating fruit acidity in diverse apples
Weighted gene co-expression network analysis (WGCNA) of fruit acidity associated genes (FAAGs) in the Ma_ and mama genotype groups. a Hierarchical cluster tree showing ten modules of co-expressed genes. Each of the 1301 FAAGs is represented by a leaf in the tree while each of the ten modules by a major tree branch. The lower panel shows modules in designated colors. b Correlation between gene total network connectivity and absolute gene significance for malate in the whole co-expression gene network. c Module-fruit acidity correlations and corresponding p-values (in parenthesis). The left panel shows ten modules (Turquoise, Black, Brown, Pink, Magnate, Red, Green, Blue, Yellow and Grey) and the number of their member genes. The right panel is a color scale for module trait correlation from −1 to 1
