Co-expression networks constructed using differently expressed genes (DEG) with absolute correlation ≥0.9 and adjusted p-value ≤0.01 by Cytoscape. The color of the nodes represents the fold change of the gene expressed in mixed forage (MF) compared to corn stover (CS). Upregulated genes are in red color, downregulated genes in blue color. Deeper the color, higher the fold changes. The size of the nodes represents the combined ranking of the degree and betweenness of the nodes (genes) in the network. Larger the size, higher the ranking. Color of the edges represent the correlation between the genes. Positive correlation is in red, negative correlation is in blue. The width of the edge represents significance of the correlation between the two genes. Larger the width, smaller the Padj
