The genetic diversity of Candida zemplinina (synonym Starmerella bacillaris), high in wine environments, is shaped by geographical location. Most analyzed C. zemplinina strains, however, have been isolated from Vitis vinifera L., disregarding the existence of other worldwide distributed Vitis species used in winemaking. In this report, we address the impact of the Vitis species and geographic location on the genetic diversity of C. zemplinina. Microsatellite genotyping analysis was applied to two remarkable populations of C. zemplinina from Argentina and Portugal (Azores Archipelago), isolated from neighboring V. vinifera and V. labrusca vineyards. The study also included a large population of previously characterized worldwide isolated C. zemplinina strains. No genetic differentiation on the basis of the Vitis species was recorded, indicating that C. zemplinina populations from neighboring V. vinifera and V. labrusca vineyards are genetically homogeneous. Our results indicate that only geographic localization significantly shapes the genetic diversity of C. zemplinina.
