Cellular variability of RpoS expression underlies subpopulation activation of an integrative and conjugative element. [PDF]

PLoS Genetics, 2012
Conjugative transfer of the integrative and conjugative element ICEclc in the bacterium Pseudomonas knackmussii is the consequence of a bistable decision taken in some 3% of cells in a population during stationary phase.

Regulatory interplay of RpoS and RssB controls motility and colonization in Vibrio cholerae

International Journal of Medical Microbiology, 2022
Cholera is a life-threatening diarrheal disease caused by the human pathogenic bacterium Vibrio cholerae. Regulatory elements are essential for bacterial transition between the natural aquatic environment and the human host.

RpoS regulates essential virulence factors remaining to be identified in Borrelia burgdorferi. [PDF]

PLoS ONE, 2012
Since the RpoN-RpoS regulatory network was revealed in the Lyme disease spirochete Borrelia burgdorferi a decade ago, both upstream and downstream of the pathway have been intensively investigated.

RpoS-regulated SEN1538 gene promotes resistance to stress and influences Salmonella enterica serovar enteritidis virulence

, 2020
Salmonella enterica serovar Enteritidis (S. Enteritidis; wild type (WT)) is a major cause of foodborne illness globally. The ability of this pathogen to survive stress inside and outside the host, such as encountering antimicrobial peptides and heat ...

The constancy of global regulation across a species: the concentrations of ppGpp and RpoS are strain-specific in Escherichia coli

BMC Microbiology, 2011
Background Sigma factors and the alarmone ppGpp control the allocation of RNA polymerase to promoters under stressful conditions. Both ppGpp and the sigma factor σS (RpoS) are potentially subject to variability across the species Escherichia coli.

Coupled induction of prophage and virulence factors during tick transmission of the Lyme disease spirochete

Nature Communications, 2023
The alternative sigma factor RpoS of Borrelia burgdorferi regulates a pathway implicated in tick transmission, mammalian infectivity and persistent infection. Here, the authors characterise the role of the RpoS negative regulator bbd18 and show that RpoS

Global effect of RpoS on gene expression in pathogenic Escherichia coli O157:H7 strain EDL933

BMC Genomics, 2009
Background RpoS is a conserved stress regulator that plays a critical role in survival under stress conditions in Escherichia coli and other γ-proteobacteria.

Regulatory roles of RpoS in the biosynthesis of antibiotics 2,4-diacetyphloroglucinol and pyoluteorin of Pseudomonas protegens FD6

Frontiers in Microbiology, 2022
The rhizosphere microbe Pseudomonas protegens FD6 possesses beneficial traits such as the production of antibiotics like pyoluteorin (Plt) and 2,4-diacetylphloroglucinol (2,4-DAPG).

IPTG induces RpoS and OspC expression.

, 2013
A total of six 5.0-ml aliquots of ΔrpoS/rpoSin spirochetes at a density of 104 cells/ml were prepared, supplemented with IPTG to final concentrations at of 0, 0.004, 0.008, 0.016, 0.032 and 0.063 mM, and induced for 8 days.
