Fig. 4From: Identification of key genes and regulators associated with carotenoid metabolism in apricot (Prunus armeniaca) fruit using weighted gene coexpression network analysisWeighted gene coexpression network analysis (WGCNA) of apricot fruit during ripening. a Hierarchical clustering showing 13 modules of coexpressed genes. Each leaf in the tree represents one gene. b Module-carotenoid correlations and corresponding p-values. The left panel shows the 13 modules and the number of genes in each module. The right panel shows a color scale for module/trait correlations from − 1 to 1Back to article page
