Eukaryogenesis From FECA to LECA: Radical Steps Along the Way

BioEssays, Volume 47, Issue 11, November 2025.
How did the last eukaryotic common ancestor (LECA) population evolve? Recent evidence shows an Asgard archaeon‐like organism acquiring a bacterium, the future mitochondrion, going from symbiosis to endosymbiosis. I postulate that almost all salient LECA characteristics could have resulted from the ensuing enhanced ATP generation and internal reactive ...

The Role of the [2Fe‐2S] Cluster of Escherichia coli IscR in Responding to Redox‐Cycling Agents

Molecular Microbiology, Volume 124, Issue 5, Page 433-448, November 2025.
Redox cycling agents like phenazine methosulfate (PMS) are known for upsetting cellular redox balance. Here we describe how PMS leads to upregulation of the ISC and SUF Fe‐S cluster biogenesis pathways in Escherichia coli when PMS oxidizes the [2Fe‐2S]1+ cluster of the transcription factor IscR, thereby derepressing the operon encoding ISC and, when a ...

Transcriptome and proteome dynamics in chemostat culture reveal how Campylobacter jejuni modulates metabolism, stress responses and virulence factors upon changes in oxygen availability [PDF]

, 2017
Campylobacter jejuni, the most frequent cause of food-borne bacterial gastroenteritis worldwide, is a microaerophile that has to survive high environmental oxygen tensions, adapt to oxygen limitation in the intestine and resist host oxidative attack ...

Effect of Chemical Additives on Maize Silage Fermentation and Aerobic Stability and on Preference and Short‐Term Intake by Goats

Grass and Forage Science, Volume 80, Issue 3, July-September 2025.
ABSTRACT This study determined the effects of a mixture of sodium benzoate and potassium sorbate (SBPS; 2 L/t fresh matter (FM)) and a formic acid‐based mixture (FASF; 3 L/t FM) on maize silage fermentation, aerobic stability, and short‐term feed intake by goats. Whole‐crop maize harvested at 280 g/kg dry matter (DM) was untreated (CON) or treated with

Antimicrobial Susceptibility Testing in Pseudomonas aeruginosa Biofilms: One Step Closer to a Standardized Method

Antibiotics, 2020
The ability of Pseudomonas aeruginosa to form biofilm during a long-term infection makes it difficult to treat patients correctly. The current clinical antimicrobial susceptibility testing methods are based on the study of planktonic strains.

Heat Stress Response in Ruditapes Decussatus: Transcriptional Regulation of Key Pathways and Novel SNPs in Antioxidant Genes

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Climate change is known to affect all levels of biology, setting at risk ecological balance. Among other organisms' groups, aquatic inhabitants, and particularly bivalves, are expected to be influenced to a greater extent owing to their inability to move to more mild temperatures.
