PtrA is functionally intertwined with GacS in regulating the biocontrol activity of Pseudomonas chlororaphis PA23

Frontiers in Microbiology, 2016
In vitro inhibition of the fungal pathogen Sclerotinia sclerotiorum by Pseudomonas chlororaphis PA23 is reliant upon a LysR-type transcriptional regulator (LTTR) called PtrA. In the current study, we show that Sclerotinia stem rot and leaf infection are

Phenazine-Embedded Copper(II) Complex as a Fluorescent Probe for the Detection of NO and HNO with a Bioimaging Application

, 2019
We report a novel phenazine-embedded fluorescent probe (2-[2-(pyridin-2-ylmethoxy)-phenyl]-1H-imidazo­[4,5-b]­phenazine, PIP), which upon complexation with Cu­(II)-ion-forming [(PIP)­CuII(Cl)] becomes nonfluorescent but regenerates fluorescence in a ...

One-pot three-component synthesis of quinoxaline and phenazine ring systems using Fischer carbene complexes

Beilstein Journal of Organic Chemistry, 2010
One-pot three-component coupling of o-alkynylheteroaryl carbonyl derivatives with Fischer carbene complexes and dienophiles leading to the synthesis of quinoxaline and phenazine ring systems has been investigated. This involves the generation of furo[3,4-

More than just a gel: the extracellular matrixome of Pseudomonas aeruginosa

Frontiers in Molecular Biosciences, 2023
Armed with an arsenal of protein secretion systems, antibiotic efflux pumps, and the occasional proclivity for explosive self-destruction, Pseudomonas aeruginosa has become a model for the study of bacterial pathogenesis and biofilm formation.

Triplet exciton band structure of crystalline phenazine [PDF]

, 1974
The structure of the lowest triplet state of crystalline phenazine was studied by optical and magnetic resonance techniques. The exciton band was characterized by a large translationally equivalent splitting (17 ± 1 cm^(−1)) which was determined from the

Enhancing the Secretion Systems: Genetic Engineering of Super Bioagents for Effective Plant Disease Control

Biotechnology and Bioengineering, EarlyView.
Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.
