Co-regulatory networks of Arabidopsis WRKY genes (click to enlarge at maximum resolution)
For every pair of WRKY genes, Pearson coefficient was calculated A: on log-transformed values and B: on untransformed values to measure the correlation of expression levels, based on approximately 2,000 microarray experiments. Each pair of correlated WRKY genes (Pearson coefficient higher than 0.6) are shown in the figure with an edge connecting them. The darkness of the edges is proportional to the value of the Pearson Coefficient. Proximity of two genes on the graph is not indicative of their relatedness. Different colours indicate different phylogenetic groups.
