5 ' untranslated region of the Pseudomonas putida WCS358 stationary phase sigma factor rpoS mRNA is involved in RpoS translational regulation

, 2008
The sigma(S) subunit of RNA polymerase is a central regulator which governs the expression of a host of stationary phase-induced and osmotically regulated genes in Gram-negative bacteria. The Pseudomonas putida rpoS gene is transcribed as a monocistronic

Comparative Genomic Analysis of Multidrug‐Resistant Escherichia coli Across Poultry–Human–Environmental Interfaces

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Whole‐genome sequencing analysis of Escherichia coli isolates from broiler, layer and sonali chickens in Bangladesh shown extensive antimicrobial resistance, diverse virulence factors, plasmid‐mediated resistance, and a highly open pangenome. Comparative genomic analyses demonstrated close genetic relationships with global strains, highlighting the One

Roles of DnaK and RpoS in Starvation-Induced Thermotolerance of \u3ci\u3eEscherichia coli\u3c/i\u3e [PDF]

, 1998
DnaK is essential for starvation-induced resistance to heat, oxidation, and reductive division in Escherichia coli. Studies reported here indicate that DnaK is also required for starvation-induced osmotolerance, catalase activity, and the production of ...

Modification of the rpoS mutant to constitutively produce surface lipoproteins doesn't alter its growth rate.

, 2013
The parental clone 13A and transformants ΔrpoS/rpoS, ΔrpoS/ospC′ and ΔrpoS/C′B′A′ were cultured in BSK-H at 33°C. Cell numbers were determined once a day for 10 days under dark-field microscopy.

RpoS is a pleiotropic regulator of motility, biofilm formation, exoenzymes, siderophore and prodigiosin production, and trade-off during prolonged stationary phase in Serratia marcescens.

PLoS ONE, 2020
Prodigiosin is an important secondary metabolite produced by Serratia marcescens. It can help strains resist stresses from other microorganisms and environmental factors to achieve self-preservation.

Interrogating the Escherichia coli Epitranscriptome Via CRISPR Interference and Nanopore Native RNA Sequencing

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Epitranscriptomics is understudied in bacteria but has the ability to modulate antimicrobial resistance, virulence and pathogenicity. Pitt et al. implement two cutting‐edge techniques: CRISPR interference and Nanopore direct RNA sequencing along with functional assays to study RNA modifications in Escherichia coli.

Crl-dependent RpoS feedback loop.

A) Bacterial two-hybrid experiment showing the interaction between RpoS and Crl. A plasmid expressing the T25 domain of adenylate cyclase was fused to the rpoS coding gene at its 5’ end and a plasmid expressing the T18 domain was fused to the wild-type ...

SbcCD regulation and localization in Escherichia coli [PDF]

, 2007
The SbcCD complex and its homologues play important roles in DNA repair and in the maintenance of genome stability. In Escherichia coli, the in vitro functions of SbcCD have been well characterized, but its exact cellular role remains elusive.

Chitobiose utilization in Borrelia burgdorferi is dually regulated by RpoD and RpoS

BMC Microbiology, 2009
Background Borrelia burgdorferi has limited biosynthetic capabilities and must scavenge N-acetylglucosamine (GlcNAc), an essential component of the microbial cell wall, from the surrounding environment.
