Gene density landscape of the genera of Botryosphaeriaceae. The two-dimensional heatmap shows the distribution of genes to gene dense or sparse regions of the genome based on their 5′ and 3′ flanking intergenic regions (FIRs). Two-dimensional heatmaps of each genus is the average across bins of all genomes in the group. The heatmaps labelled as “Botryosphaeria-clade” include the genomes of B. dothidea, B. kuwatsukai and M. phaseolina. The values on the axes are distances in base pairs and signify the upper limit of each bin. The median bin is indicated by dotted lines to assist in comparison between plots. The colours of the heatmap represents the number of genes present within each two-dimensional bin. All Botryosphaeriaceae had unimodal gene density distributions, with Eutiarosporella, Diplodia and Neofusicoccum with a greater overall gene density (smaller intergenic regions) than the other genera
