Protective host-dependent antagonism among Pseudomonas in the Arabidopsis phyllosphere

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

Contrasting patterns of microbial dominance in the Arabidopsis thaliana phyllosphere

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.

Fine-scale Population Structure of North American Arabidopsis thaliana Reveals Multiple Sources of Introduction from Across Eurasia

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.

Host-associated microbe PCR (hamPCR): accessing new biology through convenient measurement of both microbial load and community composition

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 relationship between microbial population size and disease in the Arabidopsis thaliana phyllosphere

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.

Stability of association between Arabidopsis thaliana and Pseudomonas pathogens over evolutionary time scales

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