説明

<jats:title>ABSTRACT</jats:title><jats:p>Two yeast isolates, a wine-making yeast first identified as a Mel<jats:sup>+</jats:sup>strain (ex.<jats:italic>S. uvarum</jats:italic>) and a cider-making yeast, were characterized for their nuclear and mitochondrial genomes. Electrophoretic karyotyping analyses, restriction fragment length polymorphism maps of PCR-amplified<jats:italic>MET2</jats:italic>gene fragments, and the sequence analysis of a part of the two<jats:italic>MET2</jats:italic>gene alleles found support the notion that these two strains constitute hybrids between<jats:italic>Saccharomyces cerevisiae</jats:italic>and<jats:italic>Saccharomyces bayanus</jats:italic>. The two hybrid strains had completely different restriction patterns of mitochondrial DNA as well as different sequences of the<jats:italic>OLI1</jats:italic>gene. The sequence of the<jats:italic>OLI1</jats:italic>gene from the wine hybrid strain appeared to be the same as that of the<jats:italic>S. cerevisiae</jats:italic>gene, whereas the<jats:italic>OLI1</jats:italic>gene of the cider hybrid strain is equally divergent from both putative parents,<jats:italic>S. bayanus</jats:italic>and<jats:italic>S. cerevisiae</jats:italic>. Some fermentative properties were also examined, and one phenotype was found to reflect the hybrid nature of these two strains. The origin and nature of such hybridization events are discussed.</jats:p>
