Gene co-expression network and its relationship with phenotypes of goats. (A) The dendrogram derived from the gene co-expression network of samples in the four groups (CON, LOW, MIDDLE, and HIGH). (B) The relationship between rumen parameters, dietary factors, concentration gradient and the 11 modules of genes (MEblack to MEgrey). Green colors represent negative correlations, whereas red colors represent positive correlations. Numerical values within a square represent Pearson correlation r values and P values. P values are in the behind parentheses. (C) Heat map to show gene expression of the MEblack module. The color of cells from green to red corresponds to the relative expression of genes from low to high. The numbers on the left side of the figure represent the gene IDs, while group names plus sample ID were labeled over the figure.
