Identification and Characterization of RpoS Regulon and RpoS-Dependent Promoters in Burkholderia pseudomallei

, 2016
RpoS subunit of RNA polymerase is a bacterial alternative sigma factor and major regulator important for response to a variety of stress conditions. However, RpoS-dependent genes in Burkholderia pseudomallei remained undefined.

Conversion of RpoS⁻ Attenuated Salmonella enterica Serovar Typhi Vaccine Strains to RpoS⁺ Improves Their Resistance to Host Defense Barriers

mSphere, 2018
The vast majority of live attenuated typhoid vaccines are constructed from the Salmonella enterica serovar Typhi strain Ty2, which is devoid of a functioning alternative sigma factor, RpoS, due to the presence of a frameshift mutation.

Autonomous Control of Gene Expression Using Endogenous Transcription Signals

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Autonomous cell‐based control of heterologous gene expression can simplify batch‐culture bioprocessing by eliminating external monitoring and extrinsic control of culture conditions. Existing approaches use auto‐induction media, synthetic cell‐cell communication systems, or application‐specific biosensors.

σS-Mediated Stress Response Induced by Outer Membrane Perturbation Dampens Virulence in Salmonella enterica serovar Typhimurium

Frontiers in Microbiology, 2021
Salmonella alters cellular processes as a strategy to improve its intracellular fitness during host infection. Alternative σ factors are known to rewire cellular transcriptional regulation in response to environmental stressors.

Putative trait‐based retention of oral‐derived microbes along the oral–gut axis in bamboo‐eating pandas

iMetaOmics, EarlyView.
Compared with the two herbivorous comparison species, pandas showed higher estimated oral‐source contributions and enrichment of microbial traits associated with facultative anaerobiosis, biofilm formation, and stress tolerance. These patterns are consistent with a model in which greater oral microbial input and putative host filtering may jointly ...

Negative Control of RpoS Synthesis by the sRNA ReaL in Pseudomonas aeruginosa

Frontiers in Microbiology, 2018
Pseudomonas aeruginosa (Pae) is an opportunistic human pathogen, able to resist host defense mechanisms and antibiotic treatment. In Pae, the master regulator of stress responses RpoS (σS) is involved in the regulation of quorum sensing and several ...

Function, Evolution, and Composition of the RpoS Regulon in Escherichia coli

Frontiers in Microbiology, 2020
For many bacteria, successful growth and survival depends on efficient adaptation to rapidly changing conditions. In Escherichia coli, the RpoS alternative sigma factor plays a central role in the adaptation to many suboptimal growth conditions by ...

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

Limnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.
