Molecular Microbiology, EarlyView.Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...

Molecular Microbiology, EarlyView.This study investigates in vivo the role of the flavin reductase Fre as an electron supplier to the periplasmic methionine sulfoxide reductase system MsrPQ. ABSTRACT The MsrPQ system is essential for the repair of oxidized methionine residues in periplasmic proteins, ensuring bacterial resistance to oxidative stress and envelope integrity.

Strict Aerobic Lifestyle and Anaerobic Survival of Bacteria: Inseparable Twins?
Molecular Microbiology, EarlyView.ABSTRACT For many decades the existence of strict aerobic bacteria was part of every textbook. However, considering habitats like soils or surfaces, many of these microorganisms are exposed to drastic changes in oxygen tension. A simple rain shower can change oxygen diffusion rates by a factor of 10.000.

In Salmonella Typhimurium, YiiD Modulates cAMP Levels in Lag Phase During Growth on Succinate
Molecular Microbiology, EarlyView.The YiiD enzyme, found by others to perform a redundant role in fatty acid biosynthesis, is found to be unexpectedly required for the early increase in cAMP in lag phase during growth on succinate. This intriguing finding suggests a mechanistic link may exist between fatty acid biosynthesis and catabolite repression. ABSTRACT In Salmonella Typhimurium (

The fox Operon from Rhodobacter Strain SW2 Promotes Phototrophic Fe(II) Oxidation in Rhodobacter capsulatus SB1003 [PDF]
, 2007 Anoxygenic photosynthesis based on Fe(II) is thought to be one of the most ancient forms of metabolism and is hypothesized to represent a transition step in the evolution of oxygenic photosynthesis.

New Phytologist, EarlyView.Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Metagenomic Evaluation of Oral Microbiota in Patients Affected by Oral Lichen Planus: A Pilot Study
Oral Diseases, EarlyView.ABSTRACT Objective To characterize the oral bacterial and fungal microbiota of symptomatic oral lichen planus patients undergoing topical corticosteroid therapy and to explore microbial patterns potentially associated with subsequent oral candidiasis. Methods Twelve patients with clinically and histologically confirmed OLP were enrolled.

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal
Molecular Oral Microbiology, EarlyView.ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.
