The repercussions of timing in the invasion of synthetic bacterial communities

This study shows that microbial communities are more vulnerable to invasion during transient dynamics, with invaders having greater impact before communities stabilize.

Richness and density jointly determine context dependence in bacterial interactions

The paper investigates how community richness and density affect bacterial interactions, finding that these factors influence interaction strength and predictability across different contexts.

A weaponized phage suppresses competitors in historical and modern metapopulations of pathogenic bacteria

The paper identifies a tailocin, a phage-derived element, used by Pseudomonas spp. to suppress competitors in metapopulations, showing its persistence over 170 years.

Dynamic genetic adaptation of Bacteroides thetaiotaomicron murine gut colonization

This study tracks genetic and metabolic changes in Bacteroides thetaiotaomicron during gut colonization, showing shifting gene usage and highlighting the importance of carbohydrate metabolism for long-term persistence.

Genome-wide association mapping within a single Arabidopsis thaliana population reveals a richer genetic architecture for defensive metabolite diversity

The paper conducts GWAS on a localized Arabidopsis thaliana population to uncover more genetic loci associated with defensive metabolites than previously found in broader panels.

Plant genetic effects on microbial hubs impact fitness across field trials

The paper identifies host genetic effects on microbial hubs in Arabidopsis thaliana across field trials, showing their impact on plant fitness and microbial community structure.

Species-specific gene duplication in Arabidopsis thaliana evolved novel phenotypic effects on morphological traits under strong positive selection

This study identifies a young gene in Arabidopsis thaliana that shows strong positive selection and contributes to morphological trait divergence through neofunctionalization.

Metabolic profile discriminates and predicts Arabidopsis susceptibility to virus under field conditions

This study identifies metabolic profiles that distinguish and predict Arabidopsis susceptibility to virus in field conditions.

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.

Transient interactions and influence among bacteria in field-grown Arabidopsis thaliana tissues

The paper analyzes bacterial interactions in Arabidopsis thaliana tissues across developmental stages, finding transient and mostly positive interactions that shift over time.

Natural bacterial assemblages in Arabidopsis thaliana tissues become more distinguishable and diverse during host development

The paper tracks bacterial colonization dynamics in Arabidopsis thaliana over time, showing increased tissue-specific diversity and distinct assemblages in roots and phyllosphere as plants develop.

Population genetics of the highly polymorphic RPP8 gene family

The paper investigates the polymorphism of the RPP8 gene family in Arabidopsis, finding that balancing selection contributes to its high diversity despite low heterozygosity.
