Under growth-restricting conditions bacterial populations can rapidly evolve by a process
known as stationary-phase mutagenesis. Bacterial nonhomologous end-joining (NHEJ) …

Promoters are sequences that precede transcriptional start sites and determine recognition
by RNA polymerases to initiate transcription. Most bacterial genes are regulated at the level …

Stress-promoted mutations that occur in nondividing cells (adaptive mutations) have been
implicated strongly in causing genetic variability as well as in species survival and …

In growing cells, apurinic/apyrimidinic (AP) sites generated spontaneously or resulting from
the enzymatic elimination of oxidized bases must be processed by AP endonucleases …

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

Although the biodegradation of aromatic compounds has been studied for over 40 years,
there is still much to learn about the strategies bacteria employ for growth on novel …

Transcriptional activation or 'rewiring'of silent genes is an important, yet poorly understood,
phenomenon in prokaryotic genomes. Anecdotal evidence coming from experimental …

Nucleotide excision repair (NER) is one of the most important repair systems which
counteracts different forms of DNA damage either induced by various chemicals or …

Free-living bacteria are usually thought to have large effective population sizes, and so tiny
selective differences can drive their evolution. However, because recombination is …

Bacteria use two‐component signal transduction pathways to sense both extracellular and
intracellular environment and to coordinate cellular events according to changing …
