Spatial heterogeneity and microbial terroir: balancing dispersal limitation and cultivar as drivers of microbial diversity in viticulture

This study examines spatial heterogeneity and cultivar effects on microbial communities in vineyards, finding that spatial distance, not cultivar, drives microbial diversity and community similarity.

The Genetic Basis of Microbiome Recruitment in Grapevine and its Association with Fermentative and Pathogenic Taxa

This study identifies genetic loci in grapevine that influence berry-associated microbial communities, including pathogenic fungi and fermentative yeasts, revealing broad genetic control over microbiome assembly.

A tale of two vineyards: parsing site-specific differences in bacterial and fungal communities of wine grapes from proximal vineyards, and their changes during processing in a single winery

This study tracks microbial changes in wine grapes from two nearby vineyards during processing, showing that site-specific microbial signatures persist despite shared farming practices and that winery environments contribute to the fermentation microbiome.
