Assembly of 19 complete genomes from a worldwide collection. a World map indicating the isolate names and country of origin. b Phylogenomic tree based on 50 single-copy orthologs showing reticulation using SplitsTree. c Summary of genome assembly characteristics for all isolates. The bars represent the range of minimum (shortest bar) to maximum values (longest bar) for each reported statistic. Chromosome 14–21 are accessory chromosomes. The presence or absence of accessory chromosomes in each genome is shown by green dots and empty circles for present and missing chromosomes, respectively. The linked dots for isolate YEQ92 indicate the chromosomal fusion event (see also Fig. 2)
