Abstract

We have traced the evolution patterns of 2,480 transmembrane transporters from five complete genome sequences spanning the entire Hemiascomycete phylum: Saccharomyces cerevisiae, Candida glabrata, Kluyveromyces lactis, Debaryomyces hansenii and Yarrovia lipolytica. The use of non-ambiguous functional and phylogenetic criteria derived from the TCDB classification system has allowed the identification within the Hemiascomycete phylum of 97 small phylogenetic transporter subfamilies comprising a total of 355 transporters submitted to four distinct evolution patterns named: "ubiquitous", "species- specific", "phylum-gains and-losses" or "homoplasic". This analysis identifies the transporters that contribute to the emergence of species during the evolution of the Hemiascomycete phylum and may aid to establish novel phylogenetic criteria for species classification.
