Fertilizer and cultivar affect the barley rhizobiome, while domestication age only affects growth at low nutrient levels

The paper compares old and modern barley cultivars under different fertilizer regimes, finding older cultivars perform better at low nutrients but microbiome diversity depends on cultivar and fertilizer.

Evolution of genotypic and phenotypic diversity in multispecies biofilms

This study shows how interspecies interactions in biofilms drive phenotypic diversity in Bacillus thuringiensis, with mutations in spo0A affecting matrix production and coexistence with Pseudomonas species.

Type IV-A3 CRISPR-Cas systems drive inter-plasmid conflicts by acquiring spacers in trans

This study shows type IV-A3 CRISPR-Cas systems use host adaptation machinery to update their CRISPR arrays and interfere with plasmid and phage transfer, supporting their role in plasmid competition.

An easily modifiable conjugative plasmid for studying horizontal gene transfer

This paper develops a conjugative plasmid model with an attTn7 site for efficient genetic modification to study horizontal gene transfer.

Transcriptomic responses to warming and cooling of an Arctic tundra soil microbiome

This study examines how Arctic tundra soil microbiomes respond to warming and cooling, finding delayed transcriptional changes and increased CO2 production after thaw.
