Megjegyzések:	Soil microbiota plays a critical role in the production of high-quality terroir wines by transmitting microbiota colonizing grape surfaces. Metabolites produced by the billions of these microbes are the main contributors to the minerality and fragrance of wine. The world heritage Tokaj-Hegyalja (Tokaj-foothills) region is famous of its high terroir expression. The topography and the orientation of the vineyard, geology, the composition of the ground and the climatology basically define the soil microbiome of the vineyard-plot. The soil microbiome is responsive to biotic and abiotic changes. According to our theory, the soil microbiome is a complex biological system whose composition bears the imprints made by the combined effect of all these factors. We explored the terroir of the Mád Wine Region, which is a historical wine region, located in northeastern Hungary. One prior aim of this study was to investigate the soil microbiota of Tokaj-Hegyalja region in Mád. Culture independent next-generation sequencing was applied to decipher the vitivinicultural terroir of Tokaj-Hegyalja region. We explored in detail the 100% core soil microbiota. Shotgun sequencing allows us to know what genes are present to infer the functional pathways (supporting biofunctions such as mobilization of absorbable nutrients, plant growth stimulation, production of phytohormones, cellulose-degradation, suitable soil structure, biocontrol, antimicrobial peptide and siderophore production) that are encoded. Furthermore, network analyses were performed to focus more on the connections between the microbial community members. Dissimilarity-based networks were generated to visualize the changes in complex microbial relationships. To uncover the dynamic changes in interactions between microbial species over time (veraison vs. harvest) dissimilarity-based networks were also made. It is still questionable what correlations can be demonstrated between the soil microbiome, the microbes, and the flavonoids of the must. Another central objective of this study was to investigate the correlation between must flavonoid components and the soil microbiota. According to flavonoid content we could rank must samples is four distinct categories, and descriptive microbial barcodes were made on the basis of matching soil microbiota. In conclusion, this study established links between topography, climate, soil composition and vineyard microbial community composition, biodiversity, metabolic profiles, and soil resistome load.

Megjegyzések:	A Hungarian survey of Tokaj-Mád vineyards was conducted. Shotgun metabarcoding was applied to decipher the microbial-terroir. The results of 60 soil samples showed that there were three dominant fungal phyla, Ascomycota 66.36% - 15.26%, Basidiomycota 18.78% - 14.90%, Mucoromycota 11.89% - 8.99%, representing 97% of operational taxonomic units (OTUs). Mutual interactions between microbiota diversity and soil physicochemical parameters were revealed. Principal component analysis showed descriptive clustering patterns of microbial taxonomy and resistance gene profiles in the case of the four historic vineyards (Szent Tama? s, Kira? ly, Betsek, Nyu? la?szo? ). Linear discriminant analysis effect size was performed, revealing pronounced shifts in community taxonomy based on soil physicochemical properties. Twelve clades exhibited the most significant shifts (LDA > 4.0), including the phyla Verrucomicrobia, Bacteroidetes, Chloroflexi, and Rokubacteria, the classes Acidobacteria, Deltaproteobacteria, Gemmatimonadetes, and Betaproteobacteria, the order Sphingomonadales, Hypomicrobiales, as well as the family Sphingomonadaceae and the genus Sphingomonas. Three out of the four historic vineyards exhibited the highest occurrences of the bacterial genus Bradyrhizobium, known for its positive influence on plant development and physiology through the secretion of steroid phytohormones. During ripening, the taxonomical composition of the soil fungal microbiota clustered into distinct groups depending on altitude, differences that were not reflected in bacteriomes. Network analyses were performed to unravel changes in fungal interactiomes when comparing postveraison and preharvest samples. In addition to the arbuscular mycorrhiza Glomeraceae, the families Mycosphaerellacae and Rhyzopodaceae and the class Agaricomycetes were found to have important roles in maintaining soil microbial community resilience. Functional metagenomics showed that the soil Na content stimulated several of the microbiota-related agrobiogeochemical cycles, such as nitrogen and sulphur metabolism; steroid, bisphenol, toluene, dioxin and atrazine degradation and the synthesis of folate.
