Diverse microbial communities assemble on both recalcitrant and labile carbon sources

The paper tracks microbial community dynamics on cellulose, cellulose broth, and glucose, finding stable specialist communities on cellulose and rapid succession on glucose, with comparable diversity levels.

Jumbo phage-mediated transduction of genomic islands

The paper describes the acquisition of mobile genetic elements by Pseudomonas fluorescens through jumbo phage-mediated transduction, revealing new insights into horizontal gene transfer mechanisms.

An extreme mutational hotspot in nlpD depends on transcriptional induction of rpoS

The paper identifies a mutational hotspot in nlpD linked to transcriptional induction of rpoS in Pseudomonas fluorescens SBW25, showing a 5,700-fold elevated mutation rate at this site.

Evolutionary rescue of spherical mreB deletion mutants of the rod-shape bacterium Pseudomonas fluorescens SBW25

This study shows that spherical mreB deletion mutants of Pseudomonas fluorescens SBW25 can regain fitness through mutations in Pbp1A, restoring cell size homeostasis and supporting a hypothesis about balanced transpeptidase and glycosyltransferase functions.

Microbial interactions affect the tempo and mode of antibiotic resistance evolution

This study shows that microbial interactions influence the rate and trajectory of antibiotic resistance evolution in uropathogens.

Barcoding populations of Pseudomonas fluorescens SBW25

The paper describes strategies for barcoding populations of Pseudomonas fluorescens SBW25, including design, cloning, library preparation, and quantification of barcoded lineages.
