Overview of the module networks predicted for Fusarium graminearum. a. Overview of inferred F. graminearum regulatory modules. The columns in the heatmap represent F. graminearum genes, and the rows represent the experimental conditions in the gene expression data. Modules are delimited by vertical yellow lines. Red and blue represent gene activation and suppression, respectively. b. Distribution of the number of target genes represented in a histogram. Y axis represents the frequency (count) of modules in which the number of target genes fall into the given bin sizes (X-axis). c. Distribution of the number of regulators represented in a histogram. Y axis represents the frequency (count) of modules for which the number of regulators fall into the given bin sizes (X-axis). d. An unweighted network of modules and regulators; the blue and red nodes represent regulators and modules, respectively. For clarity of visualization, the prefixes for regulator gene ID (“FGSG_”) and module (“M”) are omitted
