A qnr-plasmid allows aminoglycosides to induce SOS in Escherichia coli
eLife, 2022 The plasmid-mediated quinolone resistance (PMQR) genes have been shown to promote high-level bacterial resistance to fluoroquinolone antibiotics, potentially leading to clinical treatment failures.

RpoS plays a central role in the SOS induction by sub-lethal aminoglycoside concentrations in Vibrio cholerae. [PDF]
PLoS Genetics, 2013 Bacteria encounter sub-inhibitory concentrations of antibiotics in various niches, where these low doses play a key role for antibiotic resistance selection.

DNA damage response and cell cycle regulation in bacteria: a twist around the paradigm
Frontiers in MicrobiologyThe co-protease activity in the RecA-ssDNA complex cleaves the autorepressor LexA, resulting in the derepression of a large number of genes under LexA control.

Comparative analysis of Salmonella susceptibility and tolerance to the biocide chlorhexidine identifies a complex cellular defense network [PDF]
, 2014 peer-reviewedChlorhexidine is one of the most widely used biocides in health and agricultural settings as well as in the modern food industry. It is a cationic biocide of the biguanide class. Details of its mechanism of action are largely unknown.

Upstream of the SOS response: figure out the trigger [PDF]
Trends in Microbiology, 2006 The bacterial SOS regulon encodes a response to DNA damage that not only functions to relieve the incurred damage but also enhances adaptation through mutagenesis and the lateral spread of virulence factors. Recent papers have demonstrated that certain stimuli can indirectly generate the SOS-inducing signal by activation of endogenous DNA damage ...

Detection Of DNA Damage By Use Of Escherichia Coli Carrying recA\u27::lux, uvrA\u27::lux, And alkA\u27::lux Reporter Plasmids [PDF]
, 1997 Plasmids were constructed in which DNA damage-inducible promoters recA, uvrA, and alkA from Escherichia coli were fused to the Vibrio fischeri luxCDABE operon. Introduction of these plasmids into E. coli allowed the detection of a dose-dependent response
