抄録

Species of the genera Saccharomyces , Schizosaccharomyces , Debaryomyces and Schwanniomyces were compared from their extent of divergence in three regions from small (18S) and large (25S) subunit ribosomal RNAs comprising a total of 900 nucleotides. With the exception of the closely related Saccharomyces bayanus and S. pastorianus , which appear to have identical sequences, all other species could be distinguished by nucleotide differences in a variable region of the large subunit, and genus‐specific nucleotides were discernible in all three regions. The taxon D. tamarii differed markedly from other species and is excluded from Debaryomyces . By contrast, Schwanniomyces occidentalis showed few nucleotide differences with Debaryomyces spp. and its transfer to Debaryomyces is proposed. Schizosaccharomyces proved to be somewhat more divergent than Saccharomyces and Debaryomyces , but species differences appear insufficient for dividing the genus. Some of the factors influencing estimates of phylogenetic distances from rRNA sequences are discussed.
