Diversity and functional features of the root-associated bacteriome are dependent on grapevine susceptibility to Plasmopara viticola.

ABSTRACT:

Background

Plant health depends on beneficial interactions between the roots and their microbiomes. Despite recent progress on the role of the grapevine microbiome, the taxonomic identity and functional traits of microbial taxa specific to healthy or Plasmopara viticola-diseased plants, as well as to the susceptible or resistant cultivar are unknown. Using metabarcoding and shotgun metagenomics sequencing, we investigated the effect of downy mildew on the root-associated microbiome (rhizospheric soil, rhizoplane and endosphere) of 41B-grafted susceptible cultivar (Chardonnay) and resistant interspecific hybrid (Voltis) at flowering and veraison stages. The impact of conventional treatment on the rhizomicrobiome assembly of Chardonnay was also evaluated.
