The Reinstatement of the Genus Kloeckeraspora Niehaus (1932) (Apiculate Yeast)
キーワード:Kloeckeraspora osmophila、 Kloeckerasora vineae、 Kloeckeraspora occidentalis、 Hanseniaspora valvyensis、 Hanseniaspora uvarum
The genus Kloeckeraspora Niehaus was introduced with Kloeckerasora osmophila Niehaus. However, the genus has been neither accepted nor recognized for a long time due to the unclear generic concept. In the phylogeneetic tree based on the 26S rRNA gene D1/D2 domain sequences derived from the neighbour-joining method for the seven species, the three species assigned to the genus Kloeckeraspora represented an extremely long branch to the Hanseniaspora species. The calculated pair-wise sequence similarities were extremely low (86.2 - 88.5%). Incidentally, the sequence similarity between Vanderwatozyma polyspora and Saccharomyces cerevisiae used as reference standards was 94.0%. Within the respective genus, the similarities were 93.6 - 98.5% in the genus Kloeckeraspora and 96.3 - 99.1% in the genus Hanseniaspora. From the experimental data, the genus Kloeckeraspora should be unequivocally accepted phylogenetically and taxonomically. However, the two genera were not yet perfectly taxonomic homogeneous-natured, since there were a few species showing below 98% sequence similarity and longer phylogenetic branches in the two genera Kloeckeraspora and Hanseniaspora.

改版理由In the genus Hanseniaspora, a new taxonomic subgroup was found, designated as subgroup b-3. Therefore, the taxonomic heterogeneous-natures of the genus were increased. However, the subdivision of the genus may be difficult. In Appendix, the subgoup b-3 was mentioned.
