FIGURE 1.

Variation in size, sequence divergence, and GC-content of mtDNAs of 36 yeast species. The phylogenetic tree is based on nucleotide sequences of seven core mitochondrial genes (cob, cox1, cox2, cox3, atp6, atp8, and atp9). The very long branch leading to Hanseniaspora uvarum is shown by a thickened line at fivefold reduced scale. If two or more strains are analyzed in a species, the averages are shown for genome size and GC% (strain number in parentheses). Otherwise, the strain names are shown. Details of all strain names in the Saccharomycetaceae family are in Xiao et al. (2017), and the Saccharomycodes ludwigii strains are in Nguyen et al. (2020b).
