Fig. 1

Chromosome alignments between F. graminearum (x axis) and F. poae (y axis). The best 1:1 alignment is shown between the four chromosomes of F. graminearum and the four core chromosomes of F. poae. Red indicates best hits in the same orientation while blue indicates inversions. The short arm of F. graminearum chromosome four ends in ~1.4 Mb of rDNA repeats that are not assembled in F. poae. All F. graminearum telomeres except the telomere of the short arm of chromosome 4 are assembled. For F. poae, the same telomere is lacking as well as the one on the long arm of chromosome 1. Telomeres that are assembled are shown with green bars on the arms of the chromosomes. Two insertions into F. poae chromosome 3 are denoted with black arrows. Approximate locations of the centromeres are shown with black circles (see Additional file 18)
