Grapevine-associated bacterial and fungal microbiome Raw sequence reads
In this study, we characterized the fungal and bacterial communities inhabiting grapevine planting material from two California nurseries and followed their succession after vines were established in a commercial vineyard over three years. We profiled the endophytic and rhizosphere microbiomes of Chardonnay clone 04 and Cabernet Sauvignon clone 08 grafted on 1103P rootstock, sampling five bio-compartments, the scion and rootstock graft unions, crown, roots, and rhizosphere, at the nursery stage and at multiple time points post-planting. Using ITS and 16S amplicon sequencing, we assessed how nursery origin, plant compartment, and time shape microbial diversity, including the persistence of nursery-derived taxa and the recruitment of vineyard-associated microbes.
