Ecological Filtering by Tuber Compartments Shapes Stable Core Microbiomes That Underpin Potato Plant Growth Across Environments

Plant, Cell &Environment, EarlyView.
ABSTRACT Harnessing plant microbiomes for sustainable agriculture requires understanding not only whether they can boost crop performance, but also how ecological processes govern their assembly, stability, and functional contributions across environments.

Differential Regulation of the Phenazine Biosynthetic Operons by Quorum Sensing in Pseudomonas aeruginosa PAO1-N

Frontiers in Cellular and Infection Microbiology, 2018
The Pseudomonas aeruginosa quorum sensing (QS) network plays a key role in the adaptation to environmental changes and the control of virulence factor production in this opportunistic human pathogen. Three interlinked QS systems, namely las, rhl, and pqs,

Studies on Phenazines. XIX. Synthesis of Phenazine-carboxylic Acids.

Chemical and Pharmaceutical Bulletin, 1959
By oxidation with chromium trioxide in the presence of conc. sulfuric acid at about 5∼15°, 6-hydroxyphenazine-1- and 9-hydroxyphenazine-2-carboxylic acids were obtained from their respective methylphenazine derivatives.

Probing the molecular determinants of emission enhancement in RNA aptamer–metal complex systems

Photochemistry and Photobiology, EarlyView.
Light up aptamer: fluorophore pairs are widely used in sensing and imaging, with coordination complex fluorophores providing specific benefits due to their long‐lived emission. Here, we examined key structural and electronic features of these metal complexes to identify the requirements for productive engagement with an RNA aptamer.

Phenazines affect biofilm formation by Pseudomonas aeruginosa in similar ways at various scales [PDF]

, 2010
Some pseudomonads produce phenazines, a group of small, redox-active compounds with diverse physiological functions. In this study, we compared the phenotypes of Pseudomonas aeruginosa strain PA14 and a mutant unable to synthesize phenazines in flow cell

Hyperthermia‐induced cytotoxicity and modulation of PD‐L1 and MHC‐I expression in human non‐small cell lung cancer cell lines

Experimental Physiology, EarlyView.
Abstract Hyperthermia has recently been applied to treat human non‐small cell lung cancer (NSCLC). However, the mechanisms underlying cytotoxic sensitivity of NSCLC cells to hyperthermia are not fully understood. In this study, five NSCLC cell lines with different epidermal growth factor receptor (EGFR), Kirsten rat sarcoma and tumor protein p53 ...

Design, Synthesis, and Photovoltaic Characterization of Thiophene‐Linked Phenazine Copolymers for Solar Energy Conversion

Journal of Applied Polymer Science, Volume 143, Issue 35, September 15, 2026.
Side‐chain engineering represents an effective molecular strategy for tuning the optoelectronic properties and solid‐state organization of conjugated polymers for organic photovoltaic applications. In this study, two donor–acceptor copolymers, PBDT‐DT‐BODFPz and PBDT‐DT‐EHDFPz, were synthesized via Stille polymerization using benzodithiophene (BDT) and

Metabolites of microorganisms. 247. Phenazines from Streptomyces antibioticus, strain Tü 2706.

, 1988
From a strain of Streptomyces antibioticus seven yellow phenazines were isolated. The antibacterially most active antibiotic was identified as (-)-saphenamycin, a second one with compound DC-86-Y (saphenic acid).

Single‐Step Synthesis of Dithieno[3,2‐b:2′,3′‐e]Pyridines and Their Acid‐Dependent Optical and Photosensitising Properties

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
The synthesis of dithieno[3,2‐b:2′,3′‐e]pyridines (DTPs) is herein reported, and their optical properties are studied both experimentally and computationally. Protonation or methylation of the nitrogen atom induced bathochromic shifts in their absorption and emission spectra.
