—Distribution of intergenic distances for the five smut fungi and two related species. The distribution of the distance for each gene to the closest gene is compared for four categories: genes located within a CSEP cluster (“Clustered” category), not located in a cluster but homologous to a CSEP gene located in a cluster of another species (“Homologous” category) and genes neither clustered nor homologous to a clustered gene (“Standalone CSEP” for CSEP genes, and “Standalone” category for others). See figure 5 for legends.
