Distribution of differentially-expressed TF gene families in several types of mycorrhizal associations. We retrieved gene expression data of TF-encoding genes from roots colonized by the following species: ECM fungi (L. bicolor, A. muscaria, H. cylindrosporum, P. croceum, S. luteus, P. involutus, C. geophilum and T. melanosporum), orchid mycorrhizal fungi (S. vermifera and T. calospora) and one ericoid fungus O. maius from Kohler et al. [26]. Differentially-expressed TF genes (≥ 2.5-fold, p-value ≤0.05) (a, upregualted; b, down regulated) in mycorrhizal roots in comparison to free-living mycelium. The histograms show the distribution of TFs from each family as a percentage of the total of TFs in the genome of the corresponding fungi. The total number of regulated TFs for each fungus is indicated between brackets. Stars (*) Indicate families enriched in up-regulated genes compared to the number of these genes in the respective genome (Fisher exact test p < 0.05)
