Natural combinatorial genetics and prolific polyamine production enable siderophore diversification in Serratia plymuthica

BMC Biology, 2021
Background Iron is essential for bacterial survival. Bacterial siderophores are small molecules with unmatched capacity to scavenge iron from proteins and the extracellular milieu, where it mostly occurs as insoluble Fe3+.

Rôle du régulateur Fur et des petits ARN non codants RfrA et RfrB dans l’homéostasie du fer et la virulence de Salmonella [PDF]

, 2013
La régulation de l’homéostasie du fer est cruciale chez les bactéries. Chez Salmonella, l’expression des gènes d’acquisition et du métabolisme du fer au moment approprié est importante pour sa survie et sa virulence. Cette régulation est effectuée par la

Serotypic and Genomic Diversity of Vibrio anguillarum in Rainbow Trout Farms in Turkey: Implications for Vibriosis Control and Vaccine Candidate Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

Non-classical roles of bacterial siderophores in pathogenesis

Frontiers in Cellular and Infection Microbiology
Within host environments, iron availability is limited, which instigates competition for this essential trace element. In response, bacteria produce siderophores, secondary metabolites that scavenge iron and deliver it to bacterial cells via specific ...

Pseudomonas volatiles shape the root transcriptome and microbiome to promote plant growth under drought

New Phytologist, EarlyView.
Summary Volatile organic compounds (VOCs) emitted by soil bacteria influence interactions with other soil microbes and plants. While their potential as plant growth promoters is well recognized, their role in promoting plant resilience to abiotic stress and the underlying molecular mechanisms remain poorly understood.

Advances in Mycobacterium siderophore-based drug discovery

Acta Pharmaceutica Sinica B, 2011
Tuberculosis remains a public health threat of global proportions. Iron is a scarce resource indispensable to both host and pathogen during infection with Mycobacterium tuberculosis, the causative agent of tuberculosis.

Possible Mechanisms of Action of Two Pseudomonas fluorescens Isolates as Probiotics on Saprolegniosis Control in Rainbow Trout (Oncorhynchus mykiss Walbaum)

Animals, 2020
Probiotics have been proposed as one of the alternatives to the chemical treatments currently used in aquaculture. Recently, the possible usefulness of certain microorganisms, mainly bacteria, has been highlighted as a potential biocontrol for ...

Caractérisation des systèmes de transport du fer de Staphylococcus aureus par analyse transcriptomique [PDF]

, 2007
La quasi-totalité des organismes vivants a besoin de fer pour survivre car il tient un rôle clé dans de nombreuses réactions physiologiques. Les microorganismes ne font pas exception à cette règle. Quoiqu'un des éléments les plus abondants sur Terre, les

Etude de l’action de Pseudomonas fluorescents chez Arabidopsis thaliana [PDF]

, 2021
Les Pseudomonas fluorescents sont des bactéries promotrices de la croissance des plantes (PGPR). Ces bactéries peuvent améliorer la performance et la tolérance des plantes lors de stress environnementaux.

Rhizobacteria‐Induced Systemic Priming Against Fungal Pathogens Involves Hydroxycinnamic Acid Amides

Plant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere, a narrow region of soil surrounding roots, contains diverse microorganisms with a composition that is distinct from the surrounding soil. Some rhizosphere bacteria can trigger a heightened state of immunity in the whole plant, termed Induced Systemic Resistance (ISR).
