The role of ClpP, RpoS and CsrA in growth and filament formation of Salmonella enterica serovar Typhimurium at low temperature [PDF]

, 2014
Background: Salmonellae are food-borne pathogens of great health and economic importance. To pose a threat to humans, Salmonellae normally have to cope with a series of stressful conditions in the food chain, including low temperature.

Investigation of Effects of Hybrid Hyrax‐Mentoplate Treatment in High‐Angle Class III Patients: A Three‐Dimensional, Retrospective Study

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This retrospective study evaluated three‐dimensional effects of hybrid hyrax‐mentoplate (HH‐M) orthopaedic treatment in high‐angle Class III individuals using Cone Beam Computed Tomography (CBCT) images. Materials and Methods Pre‐treatment (T0) and post‐treatment (T1) CBCTs of 17 fully compliant high‐angle Class III patients (7 males,

Identification of Novel Members of the RpoS Regulon in Escherichia coli: The Alternative Sigma Factor, RpoS, is Regulated at the Transcriptional Level by BarA, a Member of the Family of Two-component Response Regulators. [PDF]

, 1998
The stationary phase-specific expression of many genes in free living bacteria such as Escherichia coli is controlled at the level of transcription by the alternative sigma factor RpoS encoded by the rpoS gene.

Positive feedback regulation between RpoS and BosR in the Lyme disease pathogen

mBio
In Borrelia burgdorferi, the causative agent of Lyme disease, differential gene expression is primarily governed by the alternative sigma factor RpoS (σS). Understanding the regulation of RpoS is crucial for elucidating how B.

Chloroplast Genome Characterization and Phylogenetic Implications of Reyesia and Salpiglossis (Salpiglossideae, Solanaceae)

Ecology and Evolution, Volume 16, Issue 11, November 2026.
We generated and compared the complete chloroplast genomes of Reyesia chilensis and Salpiglossis sinuata, two representative species of the tribe Salpiglossideae (subfamily Cestroideae) within Solanaceae. Comparative plastome analyses revealed highly conserved genome organization, codon usage, and repeat composition, while phylogenetic analyses ...

Inorganic polyphosphate and the induction of  rpoS  expression [PDF]

Proceedings of the National Academy of Sciences, 1997
Inorganic polyphosphate [poly(P)] levels in Escherichia coli were reduced to barely detectable concentrations by expression of the plasmid-borne gene for a potent yeast exopolyphosphatase [poly(P)ase]. As a consequence, resistance to H 2 O

RpoS and indole signaling control the virulence of Vibrio anguillarum towards gnotobiotic sea bass (Dicentrarchus labrax) larvae. [PDF]

PLoS ONE, 2014
Quorum sensing, bacterial cell-to-cell communication with small signal molecules, controls the virulence of many pathogens. In contrast to other vibrios, neither the VanI/VanR acylhomoserine lactone quorum sensing system, nor the three-channel quorum ...

Sources, Transmission, and Control of Salmonella in Vertically Integrated Broiler Chicken Production: Farm, Hatchery, and Processing Plant

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Salmonella remains one of the most important foodborne pathogens associated with poultry products, despite substantial progress in processing hygiene and antimicrobial interventions. This review critically examines the sources, transmission routes, and control strategies for Salmonella in vertically integrated broiler production systems ...

Effect of Hfq on RprA−rpoS mRNA Pairing: Hfq−RNA Binding and the Influence of the 5′ rpoS mRNA Leader Region

, 2016
The rpoS mRNA encodes a stress response transcription factor in Escherichia coli. It is one of a growing number of mRNAs found to be regulated by small RNAs (sRNA). Translation initiation of rpoS mRNA is enhanced by two sRNAs, DsrA and RprA, that pair to

RpoS role in antibiotic resistance, tolerance and persistence in E. coli natural isolates

BMC Microbiology
Background The intrinsic concentration of RpoS, the second most abundant sigma factor, varies widely across the E. coli species. Bacterial isolates that express high levels of RpoS display high resistance to environmental stresses, such as temperature ...
