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 sequences resolved the 75 species compared into 14 clades, many of which differ from currently circumscribed genera.

Yeasts of the artificial genus Candida include plant endophytes, insect symbionts, and opportunistic human pathogens. Phylogenies based on rRNA gene and actin sequences confirmed that the genus is not monophyletic, and the relationships among Candida species and allied teleomorph genera are not clearly resolved. Protein-coding genes have been useful to resolve taxonomic positions among a broad range of fungi. Over 70 taxa of the genus Candida and its allied sexually reproducing genera were therefore selected, and their phylogenetic relationships were investigated using nuclear sequences of the largest subunit and second largest subunit of RNA polymerase II gene, actin, the second subunit of the mitochondrial cytochrome oxidase gene, and D1/D2 LSU rRNA gene. The DNA sequences were analysed by maximum parsimony and Bayesian inference, resulting in the recognition of six major phylogenetic groups (A-F). Group A contains six facultative pathogenic Candida species, which seem to have derived from nonpathogenic species, while Group B contains species of Clavispora, Metschnikowia, and Pichia guilliermondii. Species of Debaryomyces form an independent group C that is related to groups A and B. Pichia fermentans and other environmental species are concentrated in Group D. Group E, containing Pichia anomala, may be a sibling to group F, which is represented by the Saccharomyces species complex.
