Fig. 3From: Comprehensive dissection of transcript and metabolite shifts during seed germination and post-germination stages in poplarWeighted gene co-expression network analysis (WGCNA) of significantly changed transcripts. a Cluster dendrogram showing global relationships among different seed germination and post-germination stages. b Hierarchical cluster tree showing coexpression modules identified by WGCNA. Each leaf in the tree is one gene. The major tree branches constitute 11 modules labeled by different colors. c Module–stage association. Each row corresponds to a module, and each column represents a specific stage. The color of each cell at the row–column intersection indicates the correlation coefficient between a module and the stage. A high degree of correlation between a specific module and stage is indicated by red. d Eigengene expression profile of each module. The y-axis indicates the value of the module eigengene; the x-axis indicates the sampled germination/post-germination stage (1–6)Back to article page
