The addition of isolated plant growth-promoting rhizobacteria and commercial arbuscular mycorrhizal fungi alters the microbiome associated with the roots of young vines. Soil and roots

Arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) are considered highly-efficient agents for conferring development to perennial crops by improving nutrition and pathogen control. In viticulture, combining AMF and PGPR is an understudied association, especially regarding the impact on soil and root microbes. The objective of this study was to evaluate the impact of single inoculation or in combination of commercial AMF (Rhizoglomus irregulare strain BEG7 and Funneliformis mosseae) and PGPR (Pseudomonas veronii and Pseudomonas brassicacearum) on Vitis vinifera (one year old grafted vine potted with soil from a declining vineyard) belowground microbiome using 16S rRNA, 18S rRNA, and ITS sequencing through MiSeq technology.
