- Intervention effect Augmented tomato phyllosphere microbiomes decreased colonization by the bacterial speck pathogen Pst across 5 independent experiments.
- Association The protective effect of the phyllosphere microbiome depends on microbial composition.
- Association The protective effect is not clearly related to overall microbial diversity.
- Intervention effect Addition of fertilizer abolished the observed microbiome-mediated protection.
- Mechanism The authors suggest microbial resource community dynamics play an important role in protection.
- Intervention effect Arabidopsis plants infected with the foliar pathogen Pseudomonas syringae pv. tomato increase root secretion of malate.
- Mechanism Malate secreted by infected Arabidopsis attracts Bacillus subtilis to the roots and leads to a stronger host immune response against Pst.
