Profiles of variant distribution by chromosome. Density profiles were computed for non-overlapping 100 kb-long sliding windows along the four chromosomes of F. graminearum. a Cumulative variant density profiles, all polymorphism considered. Star-containing intervals delineated by dotted lines indicate polymorphic islands. b Variant density profiles along the four chromosomes of F. graminearum for each strain. The density of variants belonging to the common block of diversity (observed in all French isolates) is in red; the density of variant belonging to the diversity observed with other French isolates is in blue. Black rectangles highlight selected differences between isolates. The arrows indicate the positions of centromeres
