Comprehensive and Comparative Transcriptional Profiling of the Cell Wall Stress Response in Bacillus subtilis

open access: yesMolecular 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 ...

PLP Homeostasis Protein Is Required for Efficient Maturation of Aromatic Amino Acid Aminotransferase in Salmonella enterica

open access: yesMolecular Microbiology, EarlyView.
Cellular pool of aromatic amino acid aminotransferase proteins represented as holo‐ or apo‐ enzymes, reflecting presence or absence of associated PLP. Status of PLPHP is implicated in determining the ratio of holo‐ and apo‐TyrB. ABSTRACT Pyridoxal 5′‐phosphate (PLP) is an essential cofactor required for metabolic functions including amino acid ...

In Salmonella Typhimurium, YiiD Modulates cAMP Levels in Lag Phase During Growth on Succinate

open access: yesMolecular 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 (

A Modified Cas9 Scaffold Allows Extension of the Virus‐Induced Gene Editing Technology to the Large Potyvirus Genus

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant viruses are recognized as rapid and effective vectors to deliver CRISPR‐Cas reaction components into plants, a strategy termed virus‐induced gene editing (VIGE). However, VIGE is limited by the host range of the viral vectors. Development of new viral vectors to target a broad range of plant species will potentially enable the delivery ...

DNA Methylation Shapes Seed‐Borne Microbiome and Proteome Responses During Early Maize‐Beneficial Bacteria Interactions

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.

Spectroscopic analysis of bacterial photoreactivation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.
This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.
