title: [Geographical races of certain species of ascomycetous yeasts in the Moscow and Novosibirsk regions].
abstract: Strains of three species of the ascomycetous yeasts Hanseniaspora guilliermondii, Torulaspora delbrueckii, and Debaryomyces hansenii, isolated from the above-ground parts of plants in similar biocenoses of distant geographic regions (Moscow and Novosibirsk regions), have been investigated. The strains in each species were indistinguishable with respect to phenotypic features and general DNA characteristics as determined by restriction analysis. However, comparison of the strains using PCR analysis with nonspecific primers revealed considerable intraspecific variability. From their electrophoretic patterns, the strains of the three species studied were found to cluster in accordance with the region of isolation. This phenomenon is interpreted as an example of the existence of geographical races in the major eurytopic species of yeasts.
