Sampling locations and phylogenetic relationship of Cafeteria roenbergensis strains. (a) Map representing the sampling sites of the four C. roenbergensis strains around the Americas. (b) Maximum likelihood tree reconstructed from a concatenated alignment of 123 shared single-copy core genes for the four C. roenbergensis strains and their outgroup Halocafeteria seosinensis. Numbers next to internal nodes indicate bootstrap support based on 100 iterations. The branch to the outgroup represented by a dashed line has been shortened for visualization.
