FIG 2.

Maximum likelihood phylogeny of Saccharomyces complex species from concatenation of 227 genes. H. vineae is framed in red inside the Saccharomyces complex and outside the whole-genome duplication (WGD) clade. The clade CTG groups yeasts with alternative genetic codes. Numbers close to the node match bootstrap support (BS) for those values above 70 and internode certainty (IC). The scale bar represents units of amino acid substitutions per site. The tree has a midpoint root for easier visualization.
