The role of FoxA, FiuA, and FpvB in iron acquisition via hydroxamate-type siderophores in Pseudomonas aeruginosa

Scientific Reports
Siderophores are specialized molecules produced by bacteria and fungi to scavenge iron, a crucial nutrient for growth and metabolism. Catecholate-type siderophores are mainly produced by bacteria, while hydroxamates are mostly from fungi.

Development of Tunable Materials From Well‐Defined Alendronic Acid Functionalized Polyacrylamide: An Opportunity for Actinide Decontamination

Journal of Polymer Science, EarlyView.
Alendronate‐based copolymers for Nd and Ce recovery. ABSTRACT Bisphosphonic acid groups are emerging as promising functionalities for actinide decontamination, due to their high density of chelating sites. However, the chemistry of bisphosphonate (in particular alendronate) materials remains complex and underexplored.

Magnitude and Mechanism of Siderophore-Mediated Competition at Low Iron Solubility in the Pseudomonas aeruginosa Pyochelin System

Frontiers in Microbiology, 2017
A central question in microbial ecology is whether microbial interactions are predominantly cooperative or competitive. The secretion of siderophores, microbial iron chelators, is a model system for cooperative interactions.

Flux Balance Analysis for Media Optimization and Genetic Targets to Improve Heterologous Siderophore Production

iScience, 2020
Summary: Siderophores are small molecule metal chelators secreted in sparse quantities by their native microbial hosts but can be engineered for enhanced production from heterologous hosts like Escherichia coli.

Novel applications of the tomato microbiome: Roles and considerations for agriculture, human health, and society

PLANTS, PEOPLE, PLANET, EarlyView.
Plants, like humans, have a microbiome that helps them grow, defend themselves against pathogens, acquire nutrients, and protect themselves against environmental stresses. The microbiome of tomatoes, a staple crop grown worldwide, could be utilized not only to reduce fertilizer and pesticide applications, but also to clean up harmful pollutants ...

Homéostasie des ions cuivre et fer au cours de la germination fongique. [PDF]

, 2019
La germination fongique est un processus cellulaire qui coordonne les changements métaboliques et morphologiques permettant à une spore en dormance de retrouver une forme végétative et une croissance mitotique. Les spores doivent jauger adéquatement leur

LCN2‐ACOD1 Signalling Affects the Post‐Injury Regeneration of Skeletal Muscle Through Mediating Ferroptosis

Cell Proliferation, EarlyView.
LCN2 mediates the suppression of C2C12 myoblast proliferation and myotube formation via erastin‐induced ferroptosis. Mechanistically, the LCN2‐ACOD1 axis regulates skeletal muscle growth via mitochondria‐associated ferroptosis, providing a theoretical basis for the prevention and therapy of muscle‐related diseases.

Production, characterization and iron binding affinity of hydroxamate siderophores from rhizosphere associated fluorescent Pseudomonas

Journal of Plant Protection Research, 2018
Fluorescent Pseudomonas (FP) is a major group of plant growth promoting rhizobacteria and a well-known synthesizer of siderophores, which imparts a selective advantage on rhizosphere competence and their biocontrol traits.

Plant‐produced encapsulin displays non‐typhoidal Salmonella enterica antigens and assembles into mosaic nanoparticles

The FEBS Journal, EarlyView.
This study investigates the potential of encapsulin as an antigen display platform for the development of a candidate Salmonella vaccine for poultry. Encapsulin constructs were transiently expressed in Nicotiana benthamiana where they accumulated to high levels.
