Gene co-expression network and their function in four stomachs during early development. A WGCNA cluster dendrogram and module assignment. Modules corresponding to branches are labeled with colors indicated by the color bands underneath the tree. The bar plot under the module assignment showing the gene number of each module. B Pearson correlation between modules and ages calculated based on the eigengene expression. C–F Boxplot showing the average eigengene expression of each tissue in Mred (C), Mpink (D), Mmagenta (E), and Mturquoise (F). G–J Top GO pathway enriched in Mred (G), Mpink (H), Mmagenta (I), and Mturquoise (J). Only GO terms for “Biological Process” were selected. K–N Co-expression network of Mred (K), Mpink (L), Mmagenta (M), and Mturquoise (N) constructed based on the WGCNA connection. Each module co-expression network were color-coded in module color. Each node represents one gene, the hub genes (top 10 in Mred, Mpink, and Mmagenta or top 30 in Mturquoise) were at the outermost of each networks
