Comparison of stem and leaf co-expression networks. (A) Hierarchical clustering tree (dendrogram) of genes based on stem network. Each short vertical line corresponds to one gene. The colored rows below the dendrogram indicate module membership in the stem modules and in the leaf network. (B) Hierarchical clustering tree of genes based on the leaf network. The color rows below the dendrogram indicate module membership in the leaf modules and in the stem network. (C) Cross-tabulation of stem (rows) and leaf modules (columns) showing a transcriptional modulation at 24 hpi and 2 wpi. Each row and column is represented by the corresponding module color. In the table, numbers give counts of genes in the intersection of the corresponding row and column module. The table is color-coded by -log(P), the Fisher exact test P-value, according to the color legend on the right. For each module, the eigengene expression profile is color-coded with the corresponding module color and the module size is indicated. The eigengene can be interpreted as a weighted average gene expression profile (Langfelder et al., 2011).
