Ribosomal DNA Restriction Analysis Reveals Genetic Heterogeneity in Saccharomyces cerevisiae Meyen ex Hansen

Abstract

A ribosomal DNA restriction analysis of 17 strains belonging to the Saccharomyces cerevisiae complex revealed two major groups, one of which corresponded to Saccharomyces bayanus. Our results generally correlate with previously reported genetic and molecular data and support the conclusion that S. bayanus should be reinstated as a separate taxon.
