Description of Vishniacozyma terrae sp. nov. and Dioszegia terrae sp. nov., Two Novel Basidiomycetous Yeast Species Isolated from Soil in Korea

Abstract

AbstractTwo strains, YP344 and YP579 were isolated from soil samples in Pocheon City, Gyeonggi Province, South Korea. The strains YP344 and YP579 belong to the genus Vishniacozyma and Dioszegia, respectively. The molecular phylogenetic analysis showed that the strain YP344 was closely related to Vishniacozyma peneaus. Strain YP344T differed by four nucleotide substitutions with no gap (0.70%) in the D1/D2 domain of the LSU rRNA gene and 16 nucleotide substitutions with 8 gaps (5.76%) in the ITS region. On the other hand, the strain YP579T varied from the type strain of the most closely related species, Dioszegia zsoltii var. zsoltii, by 6 nucleotide substitutions with four gaps (1.64%) in the D1/D2 domain of LSU rRNA gene and 26 nucleotide substitutions with 14 gaps (8.16%) in the ITS region. Therefore, the name Vishniacozyma terrae sp. nov. and Dioszegia terrae sp. nov. are proposed, with type strains YP344T (KCTC27988T) and YP579T (KCTC 27998T), respectively.
