Gene regulatory module 1. The average expression coefficient of this module is 0.8124. The module contains 95 genes, 73 of which have predicted GO functions. The tree-like upper part visualizes the predicted regulatory decision tree of the module, where a tree node (i.e. color bar) represents a query on the expression level of a predicted TF and a branch (i.e., arrowed edge) denotes a yes / no answer (highly / lowly expressed or not) to the query. The family names and gene IDs of the predicted TFs are listed above the nodes. A path from the top to a sub-group of conditions shown in the square box at the bottom predicts that the TFs on the path collaboratively regulate the expression of the genes in these conditions. For example, the right most path suggests that, if C2H2 is highly expressed, BTB/POZ highly expressed, and NAC highly expressed, the genes in the modules will be down regulated in the P. pachyrhizi resistant condition. The colored square box visualizes the expression levels of all genes in the module across all the conditions, where a row denotes a gene and a column denotes a stress condition. The color bar on the right illustrates a specific color with an expression value, from the lowest (green) to the highest (red).
