Competition for iron drives phytopathogen control by natural rhizosphere microbiomes.

ABSTRACT: Plant pathogenic bacteria cause high crop and economic losses to human societies^1-3. Infections by such pathogens are challenging to control as they often arise through complex interactions between plants, pathogens and the plant microbiome^4,5. Experimental studies of this natural ecosystem at the microbiome-wide scale are rare, and consequently we have a poor understanding of how the taxonomic and functional microbiome composition and the resulting ecological interactions affect pathogen growth and disease outbreak. Here, we combine DNA-based soil microbiome analysis with in vitro and in planta bioassays to show that competition for iron via secreted siderophore molecules is a good predictor of microbe-pathogen interactions and plant protection. We examined the abili
