Phylogenetic relationships among yeasts of the ? complex? determined from multigene sequence analyses

Species of Saccharomyces, Arxiozyma, Eremothecium, Hanseniaspora (anamorph Kloeckera), Kazachstania, Kluyveromyces, Pachytichospora, Saccharomycodes, Tetrapisispora, Torulaspora, and Zygosaccharomyces, as well as three related anamorphic species assigned to Candida (C. castellii, C. glabrata, C. humilis), were phylogenetically analyzed from divergence in genes of the rDNA repeat (18S, 26S, ITS), single copy nuclear genes (translation elongation factor 1alpha, actin-1, RNA polymerase II) and mitochondrially encoded genes (small-subunit rDNA, cytochrome oxidase II). Single-gene phylogenies were congruent for well-supported terminal lineages but deeper branches were not well resolved. Analysis of combined gene…
