[Genetic differentiation of the sherry yeasts Saccharomyces cerevisiae].

[Article in Russian]


Molecular genetic study of the yeast Saccharomyces cerevisiae isolated at various stages of sherry making (young wine, solera, and criadera) in various winemaking regions of Spain demonstrated that sherry yeasts diverged from the primary winemaking yeasts according to several physiological and molecular markers. All sherry strains independently of the place and time of their isolation carry a 24-bp deletion in the ITS 1 region of ribosomal DNA, whereas the yeasts of the primary winemaking lack this deletion. Molecular karyotypes of the sherry yeast from different populations were found very similar.
