Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

p-coumaric acid induces Brettanomyces bruxellensis death under winemaking conditions

open access: yesFood Microbiology
Brettanomyces bruxellensis is a significant spoilage yeast in wine, known for producing volatile phenols that alter wine aroma and quality. These compounds are formed from hydroxycinnamic acids (HCA), including ferulic, p-coumaric, and caffeic acids, which are naturally present in grapes and in wine.

Fusarium verticillioides seed inoculation modifies maize cell wall responses to subsequent Sesamia nonagrioides infestation

open access: yesPlant Biology, EarlyView.
Prior seed inoculation with Fusarium verticillioides altered the maize cell wall response to Sesamia nonagrioides attack. The combined biotic interaction promoted specific changes in lignin composition and hydroxycinnamate accumulation, suggesting that stress history modulates inducible structural defences.

The effects of a (poly)phenol‐rich food intervention on markers of exercise‐induced inflammation and oxidative stress: A randomised controlled trial

open access: yesExperimental Physiology, EarlyView.
Abstract This study examined whether consuming a (poly)phenol‐rich food before strenuous muscle‐damaging exercise can modify post‐exercise markers of inflammation and oxidative stress. Using a double‐blinded, randomised, placebo‐controlled, between‐subjects design, 26 recreationally active males (n = 15) and females (n = 11) consumed higher‐(poly ...

Non‐Destructive Analysis of Phenolic and Flavonoid Contents in Medicinal Plant Powders Using Hyperspectral Imaging and Variable Selection

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Phenolic and flavonoid contents in medicinal plants are essential to their growth and development and provide numerous health benefits, yet their quantification using traditional wet chemistry is labor‐intensive and time‐consuming. This study utilized the combination of two benchtop hyperspectral imaging (HSI) systems, namely short‐wave ...

Bioconversion of p-coumaric acid in 4-ethylphenol

open access: yes, 2008
Ce travail étudie la bioconversion de l'acide p-coumarique en 4-ethylphenol par une souche de Brettanomyces bruxellensis, levure de contamination des vins. Deux méthodes analytiques (HPLC/UV et GC/MS) ont été optimisées pour suivre la cinétique de la réaction. L'acide p-coumarique présente un problème de quantification, son instabilité aux températures
