Hopeaphenol targets histidine kinase signaling across kingdoms to suppress bacterial virulence and potentiate plant immunity

Hopeaphenol inhibits histidine kinase signaling in both bacterial pathogens and plant hosts, reducing virulence and enhancing immunity.

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

The paper investigates how prior-year drought affects leaf chemical defenses and microbial communities in aspen, finding persistent changes in phenolic compounds and fungal associations.

A Bacterial Natural Product Reshapes Phyllosphere Microbiome Composition by Blocking Carotenoid Biosynthesis

This study identifies listianol, a natural product that inhibits bacterial pigmentation by targeting carotenoid biosynthesis, altering microbial community composition on Arabidopsis under UVB exposure.

Biosynthetic gene clusters in Pseudomonas viridiflava have a fitness cost during Arabidopsis thaliana infection

The paper investigates biosynthetic gene clusters in Pseudomonas viridiflava and finds most reduce bacterial fitness during Arabidopsis thaliana infection, suggesting specialized metabolites may be more relevant for microbe-microbe interactions.

Persistent trade-offs balance competition and colonization across centuries

The paper shows a trade-off between competitive ability and host colonization in Pseudomonas populations has persisted for centuries.

Life-history trade-offs explain local adaptation in Arabidopsis thaliana

This study shows that local adaptation in Arabidopsis thaliana involves strong and variable selection on multiple traits, with trade-offs and life-history strategies affecting fitness.

Combining whole genome shotgun sequencing and rDNA amplicon analyses to improve detection of microbe-microbe interaction networks in plant leaves

The paper combines shotgun sequencing and rDNA amplicon data to improve detection of microbe-microbe interaction networks in plant leaves by addressing compositionality issues in amplicon data.
