Regulatory roles of psrA and rpoS in phenazine-1-carboxamide synthesis by Pseudomonas chlororaphis PCL1391. [PDF]

Microbiology, 2006
Production of the secondary metabolite phenazine-1-carboxamide (PCN) by Pseudomonas chlororaphis PCL1391 is crucial for biocontrol activity against the phytopathogen Fusarium oxysporum f. sp. radicis lycopersici on tomato. Regulation of PCN production involves the two-component signalling system GacS/GacA, the quorum-sensing system PhzI/PhzR and the ...

A Rapidly Responsive Sensor for Wireless Detection of Early and Mature Microbial Biofilms

Angewandte Chemie, Volume 135, Issue 40, October 2, 2023., 2023
A setup for wireless detection of early and mature microbial biofilms has been developed by combining inkjet printing of nanomaterials, chip‐less antenna, and electrogenicity of biofilms. Wireless sensing relies on the biofilm ability to electro‐reduce antenna integrated AgCl to Ag. Detection of medically relevant biofilms formed by S.

Similarities in the induction of the intracellular pathogen response in Caenorhabditis elegans and the type I interferon response in mammals

BioEssays, Volume 45, Issue 11, November 2023., 2023
This review provides a comparative analysis of the Caenorhabiditis elegans intracellular pathogen response and the mammalian type‐I interferon response. Both responses are transcriptional immunological programs that are regulated by similar features – including RIG‐I‐like signaling, perturbations to purine metabolism, proteotoxic stress, and ...

Lon protease downregulates phenazine‐1‐carboxamide biosynthesis by degrading the quorum sensing signal synthase PhzI and exhibits negative feedback regulation of Lon itself in Pseudomonas chlororaphis HT66

Molecular Microbiology, 2021
Pseudomonas chlororaphis HT66 exhibits strong antagonistic activity against various phytopathogenic fungi due to its main antibiotic phenazine‐1‐carboxamide (PCN). PCN gene cluster consists of phzABCDEFG, phzH, phzI, and phzR operons.

Introduction of the phzH Gene of Pseudomonas chlororaphis PCL1391 Extends the Range of Biocontrol Ability of Phenazine-1-Carboxylic Acid-Producing Pseudomonas spp. Strains

Molecular Plant-Microbe Interactions, 2001
Pseudomonas chlororaphis PCL1391 controls tomato foot and root rot caused by Fusarium oxysporum f. s radicislycopersici. Its biocontrol activity is mediated by the production of phenazine-1-carboxamide (PCN).

Uncovering the Role of PhzC as DAHP Synthase in Shikimate Pathway of Pseudomonas chlororaphis HT66

Biology, 2022
DAHP synthase catalyzes the first step in the shikimate pathway, deriving the biosynthesis of aromatic amino acids (Trp, Phe and Tyr), phenazine-1-carboxamide, folic acid, and ubiquinone in Pseudomonas chlororaphis.

The salt-tolerant phenazine-1-carboxamide-producing bacterium Pseudomonas aeruginosa NF011 isolated from wheat rhizosphere soil in dry farmland with antagonism against Fusarium graminearum.

Microbiology Research, 2020
Fusarium head blight (FHB) disease caused by Fusarium graminearum (Fg) seriously affects the yield and quality of wheat. In this study, after bacterial community analysis of two wheat rhizosphere soils, the genus Pseudomonas was shown to be enriched in ...
