Comparison of natural yeast hybrids

ABSTRACT: Analysis of genomic variation in several Saccharomyces cerevisiae x S. kudriavzevii natural hybrids S. cerevisiae and S. kudriavzevii yeasts have been described among wine strains. These strains exhibit enological properties of interest for the wine industry. A preliminary characterization of these hybrids showed a trend to reduce the S. kudriavzevii fraction of the hybrid genome. As a first approach to understand the mechanisms involved in the genome changes occurred after hybridization that may account for differences in their enological properties, we characterized the genomic constitution of several wine S. cerevisiae x S. kudriavzevii strains by using a combined approach based on the RFLP analysis of gene regions, comparative genome hybridizations with S. cerevisiae DNA arrays, ploidy
