Evidence for the key roles of the Pseudomonas syringae mobilome in shaping biotic interactions

This study examines the role of the mobilome, particularly prophages, in shaping biotic interactions in Pseudomonas syringae by analyzing 590 genomes and identifying defense mechanisms and effectors.

Phage as signatures of healthy microbiomes

This paper examines whether viromes can serve as signatures of microbiome health by analyzing published studies on phage and bacterial diversity in healthy and dysbiotic states.

Genomic characterization of Pseudomonas syringae pv. syringae from Callery pear and the efficiency of associated phages in disease protection

This study characterizes Pseudomonas syringae isolates from Callery pears and evaluates a phage's biocontrol efficiency against plant disease.

Transmission mode shapes host specialization of the phyllosphere microbiome

The paper tests how microbial transmission between same- and different-species plants affects microbiome specialization, finding that conspecific transmission leads to more specialized microbiomes.

Within-host adaptation alters priority effects within the phyllosphere microbiome

The paper shows that within-host adaptation changes priority effects in the phyllosphere microbiome by altering ecological interactions and host impact.

Leaf side determines the relative importance of dispersal versus host filtering in the phyllosphere microbiome

The paper examines bacterial communities on upper and lower leaf surfaces across 24 plant species, finding that lower leaf surfaces have lower taxonomic richness and are more influenced by host filtering than dispersal.

Early phyllosphere microbial associations impact plant reproductive success

The paper tests how adding a synthetic microbial community to greenhouse-grown tomato plants improves fruit production and reproductive success.

Relative abundance data can misrepresent heritability of the microbiome

This paper shows that using relative abundance data to estimate microbiome heritability can lead to imprecise, overestimated, and biased results due to taxon interdependencies, large sample sizes, and microbial co-abundances.

Historical contingency drives compensatory evolution and rare reversal of phage resistance

This study shows that historical contingency influences the evolution of phage resistance in bacteria, with some mutations being reversible and others entrenched, affecting the long-term persistence of resistance.

Induction of autotetraploidy and microbiome associations mediate differential responses to pathogens

The paper investigates how autotetraploidy in Arabidopsis affects microbiome interactions and pathogen resistance, finding polyploids are more resistant but less reliant on beneficial bacteria.

Plant neighborhood shapes diversity and reduces interspecific variation of the phyllosphere microbiome

This study shows that plant neighborhood influences phyllosphere microbiome diversity and reduces interspecific variation over time.

Water Stress and Disruption of Mycorrhizae Induce Parallel Shifts in Phyllosphere Microbiome Composition

The paper examines how water stress and mycorrhizal disruption affect tomato phyllosphere microbiome composition, finding parallel shifts in bacterial and fungal communities.

High-throughput mapping of the phage resistance landscape in E. coli

This study maps host genetic determinants of phage resistance in E. coli using high-throughput genetic screens, identifying both known and novel resistance factors across 14 phages.

Biofilm structure promotes coexistence of phage-resistant and phage-susceptible bacteria

The paper uses simulations and experiments to show that biofilm structure promotes coexistence of phage-resistant and phage-susceptible bacteria compared to planktonic cultures.

Protective microbiomes can limit the evolution of host pathogen defense

The paper develops a model showing that protective microbiomes can reduce host immune vigilance by altering evolutionary pressures on immunity.

Why evolve reliance on the microbiome for timing of ontogeny?

This paper explores how microbiome interactions influence host ontogenetic timing through evolutionary theory and potential applications in agriculture and disease control.

Successive passaging of a plant-associated microbiome reveals robust habitat and host genotype-dependent selection

The paper shows that successive passaging of a tomato phyllosphere microbiome can select for a stable, host genotype-dependent community that resists invasion by the original community.
