Intergenic distances of all genes in Pyrenophora tritici-repentis isolate I-73–1. The 3′ intergenic length (x-axis) is the distance (bp) from the 3′ end of the current gene to the 5′ end of next, and the 5′ intergenic length (y-axis) is the distance from the 3′ end of the previous gene to the 5′ end of the current gene. Inset (top right) shows dN/dS ratios for genes from the 90th ITL percentiles (i.e. genes furthest from others and genes nearest to others; outliers omitted for clarity)
