Grafted Grapevine Metagenome

While grapevine rootstocks are essential to commercial viticulture, researchers still lack a complete understanding how these root systems and their associated microbiomes influence the vine's mineral nutrition. Previous research has shown that rootstocks with similar pedigrees, reflecting the limited number of parental genotypes in the breeding pool, affect both the vine's elemental profile and microbiome composition. Here, we used a rootstock diversity trial with ten rootstock genotypes grafted to one of two scions to simultaneously characterize the rhizosphere metagenome and elemental composition of individual vines, including both berries and roots.
