Distribution of DNA-binding domains among F. graminearum transcriptional regulators. (A) Barplots showing the distribution of DNA-binding domains present in D-TAPs (‘All D-TAPs’), and top- and second-tier regulators. ‘#DBDs’: number of DNA-binding domains detected; p-value (displayed as ‘–log10(p)’) obtained from Fisher’s exact test when comparing the top and second-tier distributions with the background. (B) Distributions of the pTF DBDs. (C) Heatmap visualizing the Pearson correlation coefficients of the DBD abundances – the pairwise correlation between the fraction of background, top and second-tier regulator and pTF DBDs.
