Summary: This projects objectives were 1) Characterize the effect of apple rootstock genotype on composition of the rhizosphere and orchard soil microbiome. 2) Define differences in the natural chemical compound profile produced by rootstock cultivars that differ in inhibiting deleterious (pathogenic) or attracting beneficial rhizosphere microorganisms. 3) Test the composite and independent impacts of natural chemical compounds on specific microbes or the soil microbiome to verify functional role in inhibition of deleterious microbes or attraction of beneficial microbes. 4) Determine effects of apple rootstock genotype on rhizosphere soil pH, contrasting rootstocks harboring different rhizosphere microbiomes of functional importance.
