Stationary-phase mutations occur in populations of stressed, nongrowing, and slowly
growing cells and allow mutant bacteria to overcome growth barriers. Mutational processes …

A novel experimental system to study mutation in starving bacteria was designed, relying on
the activation of a promoterless phenol degradation operon of Pseudomonas putida. The …

In a growth-restricting environment, mutants arise that are able to take over bacterial
populations by a process known as adaptive mutation or stationary-phase mutation. This …

One of the popular ideas is that decline in methyl-directed mismatch repair (MMR) in carbon-
starved bacteria might facilitate occurrence of stationary-phase mutations. We compared the …

It is still an open question whether mutation rate can vary across the bacterial chromosome.
In this study, the occurrence of mutations within the same mutational target sequences at …

RpoS is a bacterial sigma factor of RNA polymerase which is involved in the expression of a
large number of genes to facilitate survival under starvation conditions and other stresses …

Oxidative damage of DNA is a source of mutation in living cells. Although all organisms have
evolved mechanisms of defense against oxidative damage, little is known about these …

Adaptive mutations are mutations that occur in nondividing or very slowly dividing microbial
cells during prolonged nonlethal selection and that are specific to the challenge of the …

We have recently described the presence of a high proportion of Pseudomonas aeruginosa
isolates (20%) with an increased mutation frequency (mutators) in the lungs of cystic fibrosis …

In prokaryotic mismatch repair the MutS protein and its homologs recognize the mismatches.
The mutS gene of naturally transformable Pseudomonas stutzeri ATCC 17587 (genomovar …
