AI Article Synopsis
- L. ssp. (Gmelin) Hegi is recognized as the original plant for many current grape cultivars, but is now threatened due to climate change and pests, leading to its listing on the IUCN Red List in 1997.
- The research gathered grape berry samples from 29 locations across Azerbaijan, Georgia, Italy, Romania, and Spain, isolating 3431 yeast colonies which were identified as 49 different species.
- The study emphasized the importance of natural environments in promoting yeast biodiversity, offering potential solutions to challenges faced in winemaking.
Article Abstract
L. ssp. (Gmelin) Hegi is recognized as the dioecious parental generation of today's cultivars. Climatic change and the arrival of pathogens and pests in Europe led it to be included on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species in 1997. The present work focused on the study of culturable yeast occurrence and diversity of grape berries collected from wild vines. Sampling was performed in 29 locations of Azerbaijan, Georgia, Italy, Romania, and Spain. In total, 3431 yeast colonies were isolated and identified as belonging to 49 species, including , by 26S rDNA D1/D2 domains and ITS region sequencing. Isolates of were also analyzed by SSR-PCR obtaining 185 different genotypes. Classical ecology indices were used to obtain the richness (S), the biodiversity (H'), and the dominance (D) of the species studied. This study highlights the biodiversity potential of natural environments that still represent a fascinating source of solutions to common problems in winemaking.
