Network analysis dendrogram showing co-expression modules identified by WGCNA of DEGs. a Dendrogram plot with color annotation. The genes in the same branch could be assigned to different modules. The main tree branches form eight modules labeled with different colors. b Module-sample association. Each row corresponds to a module. Each column corresponds to a specific material. The color of each cell at the row-column intersection indicates the coefficient of correlation between the module and the material. A high degree of correlation between a particular module and the material is indicated by the red color. c, d Significantly enriched KEGG signaling pathways of differentially expressed genes derived from modules MEblue and MEturquoise, respectively
