Bacterial communities associated with plant roots play an important role in the suppression of soil-borne pathogens, and multispecies probiotic consortia may enhance disease efficacy. Here we introduced defined Pseudomonas species into naturally complex microbial measured importance community diversity for their survival bacterial pathogen Ralstonia solanacearum tomato rhizosphere microbiome. The increased increasing diversity. Further, high reduced density decreased incidence due to both intensified resource competition interference pathogen. These results provide novel mechanistic insights elevated by diverse rhizospheres. Ecologically based assembly rules could thus a key engineering functionally reliable microbiome applications.The demand food supply requires more-efficient control diseases. use probiotics, i.e., occurring antagonists competitors that suppress has recently reemerged as promising alternative agrochemical use. It is, however, still unclear how many which strains should choose constructing effective consortia. present general ecological framework assembling on vitro characterization functioning. Specifically, show enhances microbiome, leading via We propose these guidelines can be put test more widely future.
