RIKEN team establishs high yeast diversity in Japan

A total of 1021 yeast strains was isolated from soil samples and plant materials collected from Japan’s subtropical Iriomote Island and the cool temperate Rishiri Island. Based on sequence analyses of the D1/D2 domain of the LSU rRNA gene, these 1021 strains were tentatively classified into 183 species, with apparent new species accounting for approximately half of the total species isolated (60 and 46, Iriomote and Rishiri, respectively). The yeast species composition was statistically different between the two sites with only 15 species in common. Rarefaction curves of respective sources/areas gave distinctive patterns when the threshold of sequence identity became broader, indicating that the yeast diversity was distinct at the different taxonomic levels compared.
