Frontiers in Microbiology, 2018 Pseudomonas aeruginosa causes many biofilm infections, and the rugose small-colony variants (RSCVs) of this bacterium are important for infection. We found here that inactivation of PA2444, which we determined to be a serine hydroxymethyltransferase ...

Microbial Biotechnology, Volume 19, Issue 8, August 2026.TolC is identified as an essential component of the mixed‐linkage β‐glucan (MLG) biosynthetic machinery in Sinorhizobium meliloti, likely enabling polymer export. Co‐expression of tolC, bgsBA, and pleD* significantly enhances MLG production and enables its synthesis in non‐native bacterial hosts.

To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility
Molecular Microbiology, Volume 126, Issue 2, Page 173-189, August 2026.Motility cessation in bacteria is a key regulatory strategy that provides multiple survival advantages including enhanced community cooperation, niche adaptation and evasion of host immune responses. This process is controlled by associated mechanisms such as post‐translational modifications and second messenger signalling that stabilise non‐motile ...

An evolutionary optimization of a rhodopsin-based phototrophic metabolism in Escherichia coli
Microbial Cell Factories, 2017 Background The expression of the Gloeobacter rhodopsin (GR) in a chemotrophic Escherichia coli enables the light-driven phototrophic energy generation. Adaptive laboratory evolution has been used for acquiring desired phenotype of microbial cells and for

Molecular Microbiology, Volume 126, Issue 1, Page 98-110, July 2026.Single amino acid substitutions in the global regulator CodY can alter nutrient sensing and virulence regulation in Clostridioides difficile. We show that the CodY(Y146N) and CodY(V58A) variants display altered ligand binding and reduced promoter binding, leading to derepression of toxin regulatory pathways and increased virulence in vivo.

Diguanylate Cyclases Control Magnesium-Dependent Motility ofVibrio fischeri [PDF]
Journal of Bacteriology, 2006 ABSTRACTFlagellar biogenesis and hence motility ofVibrio fischeridepends upon the presence of magnesium. In the absence of magnesium, cells contain few or no flagella and are poorly motile or nonmotile. To dissect the mechanism by which this regulation occurs, we screened transposon insertion mutants for those that could migrate through soft agar ...

Forecasting Root Rot Disease through Predictive Microbial Functional Profiling
Advanced Science, Volume 13, Issue 23, 23 April 2026.Predicting soil‐borne disease moves beyond observation with a framework that elevates microbial functional genes into reliable forecasting biomarkers. By coupling targeted qPCR assays for core stress‐response genes with machine learning, this method detects root rot risks in pre‐symptomatic soils with over 80% accuracy.

Cyclic di-GMP-dependent signaling pathways in the pathogenic Firmicute Listeria monocytogenes.
PLoS Pathogens, 2014 We characterized key components and major targets of the c-di-GMP signaling pathways in the foodborne pathogen Listeria monocytogenes, identified a new c-di-GMP-inducible exopolysaccharide responsible for motility inhibition, cell aggregation, and ...
