Elucidating Softening Mechanism of Honey Peach (Prunus persica L.) Stored at Ambient Temperature Using Untargeted Metabolomics Based on Liquid Chromatography-Mass Spectrometry

open access: yesHorticulturae, 2023
Peach fruit softening is the result of a series of complex physiological and biochemical reactions that influence shelf life and consumer acceptance; however, the precise mechanisms underlying softening remain unclear. We conducted a metabolomic study of

Regulation of D-galacturonate metabolism in Caulobacter crescentus by HumR, a LacI-family transcriptional repressor [PDF]

open access: yes, 2013
The oligotrophic freshwater bacterium Caulobacter crescentus encodes a cluster of genes (CC_1487 to CC_1495) shown here to be necessary for metabolism of D-galacturonate, the primary constituent of pectin, a major plant polymer.

Bench-to-bedside review: The role of glycosaminoglycans in respiratory disease. [PDF]

open access: yes, 2006
The extracellular matrix (ECM) plays a significant role in the mechanical behaviour of the lung parenchyma. The ECM is composed of a three-dimensional fibre mesh that is filled with various macromolecules, among which are the glycosaminoglycans (GAGs ...

Taxonomic and functional shifts in the microbiome of severely obese, prediabetic patients: Ketogenic diet versus energy‐matched standard diet

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Obesity and type 2 diabetes mellitus (T2DM) are among the leading global health challenges of the 21st century. While caloric restriction remains the cornerstone of weight loss interventions, ketogenic diets (KD), characterised by low carbohydrate and high fat intake, have been shown to improve metabolic health partly by modulating the ...

Ion activities and potassium uptake mechanisms of glial cells in guinea-pig olfactory cortex slices. [PDF]

open access: yes, 1987
1. Double-barrelled ion-sensitive micro-electrodes were used to measure changes in the intracellular activities of K+, Na+ and Cl- (aiK, aiNa, aiCl) in glial cells of slices from guinea-pig olfactory cortex during repetitive stimulation of the lateral ...

Glucuronoyl Esterase of Pathogenic Phanerochaete carnosa Induces Immune Responses in Aspen Independently of Its Enzymatic Activity

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Microbial enzymes expressed in plants add new functionalities but occasionally trigger undesirable immune responses. Phanerochaete carnosa glucuronoyl esterase (PcGCE) hydrolyses the bond between lignin and 4‐O‐methyl‐α‐D‐glucuronic acid substituent of glucuronoxylan.

OsSTK‐Mediated Sakuranetin Biosynthesis and Carbon Flux Orchestrate Growth and Defence in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plants balance resource energy allocation between growth and immunity to ensure survival and reproduction under limited availability. This study reveals that rice cultivars with elevated sucrose levels boost resistance to the fungal pathogen Magnaporthe oryzae by accumulating the phytoalexin sakuranetin, regulated by the transcription factor ...
