This study investigates how Arabidopsis thaliana responds to Pseudomonas viridiflava infection, finding that the JA/ethylene pathway influences susceptibility and that immune responses vary between accessions.

The paper investigates strain-level interactions between commensal and pathogenic Pseudomonas in the Arabidopsis phyllosphere, showing host-mediated protection against pathogens.

The paper compares the ecological roles of Sphingomonas and Pseudomonas in the phyllosphere of Arabidopsis thaliana, finding Sphingomonas to be more adaptable but a poor competitor in dead leaves.

The paper assesses microbial load and composition in Arabidopsis thaliana phyllosphere using shotgun metagenomics, finding high microbial loads correlate with pathogen proliferation and reduced diversity.

The paper surveys Pseudomonas in Arabidopsis thaliana over multiple years and sites, finding that pathogenic sublineages coexist without a single dominant strain overtaking populations.
