Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery

Molecular Microbiology, EarlyView.
The Haloferax volcanii tubulin‐like protein CetZ1 is required for rod‐cell morphogenesis and motility. We show that CetZ1 loss or GTPase inactivation impairs assembly of the motility machinery, including the archaellum base protein ArlD, the chemotaxis adaptor CheW1, and the response regulator CheY.

Regulation by the Transcriptional Regulator YdcI in E. coli and (p)ppGpp‐Dependent Activation of ydcI Expression

Molecular Microbiology, EarlyView.
YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

A Mobile Glycosylation Locus Modulates Cell Wall Architecture in Lactobacillus crispatus

Molecular Microbiology, EarlyView.
Serial propagation of Lactobacillus crispatus triggers transposon‐mediated loss of a mobile glycosylation gene fragment (GT3), destabilising the glycosyltransferase complex and remodelling the cell wall with 20%–25% thinner peptidoglycan, while sugar composition remains unchanged.

α‐1,3‐Glucan Is Required for Cell Wall Integrity and Full Virulence of Colletotrichum graminicola, but Not for Evasion of PAMP‐Triggered Immunity

Molecular Microbiology, EarlyView.
Abbreviated Summary The role of the major fungal cell wall polymer α‐1,3‐glucan in plant infection is poorly understood. Deletion mutants of the maize anthracnose fungus Colletotrichum graminicola lacking all three α‐1,3‐glucan synthase genes differentiated severely distorted biotrophic hyphae in planta, and virulence was strongly reduced.

Spectroscopic analysis of bacterial photoreactivation

Photochemistry 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.
