For most disease-suppressive soils, the microbes and mechanisms involved in pathogen control are unknown. By coupling PhyloChip-based metagenomics of the rhizosphere microbiome with culture-dependent functional analyses, we identified key bacterial taxa and genes involved in suppression of a fungal root pathogen. More than 33,000 bacterial and archaeal species were detected, with Proteobacteria, Firmicutes, and Actinobacteria consistently associated with disease suppression. Members of the ?-Proteobacteria were shown to have disease-suppressive activity governed by nonribosomal peptide synthetases. Our data indicate that upon attack by a fungal root pathogen, plants can exploit microbial consortia from soil for protection against infections.  aBiological control  aFungal diseases of plants  aPlant diseases and disorders  aRhizosphere  aRoot diseases  aSuppressive soils  aBactéria  aControle biológico  aDoença de planta  aDoença fúngica  aRizosfera  aPeptide synthetases1 aKRUIJT, M.1 aBRUIJN, I. de1 aDEKKERS, E.1 aVOORT, M. van der1 aSCHNEIDER, J.
