Megjegyzések:	Several studies demonstrate that wine-terroirs are strongly influenced by the epiphytic microbiota of vines (Vitis vinifera) representing a potential source of inoculum for wine fermentation. This study was carried out to explore the impact of biogeography and four different agronomical practices (conventional-1, -2, organic and uncultivated) on the composition and metabolic profiles of microbial communities. Both amplicon-based ribosomal DNA internal transcribed spacer phylotyping and shotgun metagenomics were used to barcode the complex microbial communities and to carry out functional metagenomics. Two Hungarian geographical territories (Tokaj wine region and Pallag) were investigated. Tokaj wine region has been declared a World Heritage Site in 2002 under the name Tokaj Wine Region Historic Cultural Landscape which is the origin of ?Tokaji aszú" wine, the world's oldest botrytized wine. Soil, vine bark and grape berry samples were collected from vineyards evidencing different agronomic managements. The applied culture-independent strategy provides a better understanding of the population composition, diversity and potential metabolic profiles of microbes present in the habitat. For each sample, the extracted genomic DNA samples were quantified and checked for purity. To sequence the V3 and V4 hypervariable regions of prokaryotic 16S rRNA genes standard library preparation was performed according to Illumina 16S metagenomic sequencing library preparation protocol. Furthermore, the trunk bark and grape berries were shotgun sequenced. In general, the alpha diversity metrices of soil samples proved to be significantly higher than those of the trunk-bark samples. As agronomic management regards, significantly lower biodiversity was experienced due to conventional in comparison to biodynamic and fellow agronomical practices irrespectively of the geography (Tokaj wine region vs, Pallag Botanical and Exhibition Garden). We managed to determine the core microbiota of wine-bark and soil samples of the vine samples and we estimated the beta-diversities of the different vitivinicultural terroirs. Our knowledge about the influence of geography and agronomical practices of vine bark- and soil associated microbiomes might also support the wine industry to understand the roles of microorganisms on the entire winemaking process, from vineyard to cellar.
