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.

This study identifies multiple introduction sources of North American Arabidopsis thaliana from Eurasia using genomic data and finds evidence of admixture increasing haplotype diversity and immune-related selection.

The paper introduces hamPCR, a method to measure microbial load and community composition from amplicon sequencing, demonstrating its accuracy and scalability across different host-microbe systems.

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.
