Chloramphenicol and gentamicin reduce resistance evolution to phage {Phi}X174 by suppressing a subset of E. coli C LPS mutants

Large-scale duplication events underpin population-level flexibility in tRNA gene copy number in Pseudomonas fluorescens SBW25

The paper shows that Pseudomonas fluorescens SBW25 can rapidly generate tRNA gene set diversity through unstable large-scale duplications, which can preserve or alter tRNA gene copy numbers depending on selection pressure.

Stepwise evolution of E. coli C and {varphi}X174 reveals unexpected lipopolysaccharide (LPS) diversity

This study evolves E. coli C and its phage {Phi}X174 to reveal unexpected LPS diversity and show that current LPS biology understanding is insufficient to predict phage adaptation.

The layered costs and benefits of translational redundancy

This study manipulates redundancy in translation components of E. coli and finds nutrient-dependent fitness costs and benefits, revealing a layered hierarchy of redundancy organization.

Evolutionary flexibility in routes to mat formation by Pseudomonas

This study compares mat formation mechanisms in three Pseudomonas strains, showing different exopolysaccharides and genetic routes for mat formation.

Host-parasite coevolution promotes innovation through deformations in fitness landscapes

The paper tests how coevolution between a virus and its bacterial host affects the likelihood of evolutionary innovation by altering fitness landscapes.

Sustained coevolution of phage Lambda and Escherichia coli involves inner as well as outer membrane defenses and counter-defenses

This paper shows that E. coli and phage Lambda coevolve through interactions at both outer and inner membranes, with E. coli mutating genes to resist phage DNA ejection and phage evolving to bypass these defenses.

The birth of a bacterial tRNA gene by large-scale, tandem duplication events

This study shows that tRNA gene sets in bacteria can evolve through large-scale duplications of existing tRNA genes, compensating for the loss of a single-copy gene.

Repeated phenotypic evolution by different genetic routes: the evolution of colony switching in Pseudomonas fluorescens SBW25

This study shows that two independent lineages of Pseudomonas fluorescens SBW25 evolved colony switching through different genetic mutations, with Line 6 relying on an rpoD mutation affecting ribosome expression.

Identification And Characterization Of Domesticated Bacterial Transposases

The paper identifies and characterizes RAYTs, a class of bacterial transposases, showing they are domesticated and functionally integrated into host genomes.
