RT conference output T1 Genetic diversity of yeasts isolated from Eurasian populations of Vitis vinifera ssp Sylvestris (Gmelin) Hegi T2 Diversidad genética de levaduras aisladas a partir de uvas de Vitis vinifera ssp. Sylvestris (Gmelin) Hegi en el área Euroasiática A1 Cordero Bueso, Gustavo Adolfo A1 Vigentini, Ileana A1 Foschino, Roberto A1 Maghradze, David A1 Manuel Cantoral, Jesús A2 BiomedicinaBiotecnología y Salud Pública AB Vitis vinifera L. ssp. Sylvestris (Gmelin) Hegi is recognized as the dioecious parental generation oftoday’s cultivars. Climatic change and the arrival in Europe of pathogens and pests have led it to be includedon the IUCN Red List of Threatened Species in 1997. At best of our knowledge, no studies on microbialpopulations of grape-berry surfaces have been done. The present work has been focused on the study of yeastoccurrence and diversity on grape-berries collected from wild vines. Final outputs have allowed: i)to obtainprecise information about yeast communities; ii) to provide an objective framework for the classificationof the broadest range of species according to their extinction risk; iii) to select attractive yeast strains fortheir biotechnological potential, offering new opportunities to winemakers. Sampling plan was performed inAzerbaijan, Georgia, Italy, Romania and Spain. In all, 3180 yeast colonies were isolated and identified asbelonging to 50 species, including Saccharomyces cerevisiae, by 26S rDNA D1/D2 domains and ITS regionsequencing. Isolates of S. cerevisiae were also analysed by SSR-PCR obtaining 163 different genotypes. Thisstudy highlights the biodiversity potential of pristine environments that still represent a fascinating source toface common problems in winemaking.
