Outline of Final Research Achievements

According to the "One Fungus = One Name (1F=1N)" principle implemented by the Code of Nomenclature for algae, fungi, and plants (Melbourne code), yeast phylogeny is studied to reclassify the polyphyletic taxa under the collaboration with the yeast taxonomic community in the world. For making a backbone tree with high quality, we constructed phylogenetic trees based on (1) the 30 orthologous genes selected from draft genome data and (2) whole genomes, using the Trichosporonales species as an example. We also introduced to use the genome data for obtaining the traits/properties that distinguish one genus from the other, as anamorphic yeast taxa generally lack the morphological characteristic which has been employed for the most important taxonomic criterion in fungi. The data obtained suggests that our strategy would contribute to the taxonomy for other yeast taxa.
