Ascorbate function and associated transport systems

, 2000
: Ascorbate is present in different cell compartments of higher plant cells. At a physiological level, the best-studied phenomena involving ascorbate is its participation in an oxygen scavenging pathway in the chloroplast known as the ascorbate ...

Enzymes of the glutathione-ascorbate cycle in leaves and roots of rhizobia-inoculated faba bean plants (Vicia faba L.) under salinity stress.

, 2014
Grain legumes such as the faba bean (Vicia faba L.) used for human as well as animal nutrition, are of great importance especially in countries under Mediterranean climate like Morocco, which is mainly characterized by semi-arid and arid climates and by ...

Effect of Water Suppression and Metabolite Cycling on Quantification of 1H MRS Spectra in the Human Brain at 3 Tesla

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 542-547, August 2026.
ABSTRACT Purpose This study investigates the effect of VAPOR water suppression and metabolite cycling on metabolite quantification and macromolecules in proton magnetic resonance spectroscopy. Methods Single‐voxel semi‐LASER spectra (TR/TE = 3000/28 ms) and metabolite‐nulled spectra (macromolecules) were acquired in five healthy subjects in the ...

In Situ pH Determination Using 1H‐MRS Acetate Chemical Shift for Noninvasive Postmortem Examinations

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
The chemical‐shift difference between acetate and myo‐inositol measured by MRS enables estimation of pH in the acidic range. Noninvasive pH assessment in forensic investigations is demonstrated in 58 cases and validated by measurements in extracted tissue.

Hydrogen sulfide enhances salt tolerance in sorghum by activating the chloroplastic AsA–GSH cycle to sustain photosynthesis

Frontiers in Plant Science
Soil salinization poses a severe threat to global food security by reducing crop productivity, particularly in semi-arid regions where sorghum (Sorghum bicolor L.) is a major cereal crop. Hydrogen sulfide (H₂S) has recently been recognized as a signaling

Structural basis of ligand selectivity in FAD/NAD(P)H‐dependent dehydrogenases: insights from trypanothione reductase and type II NADH dehydrogenase

Protein Science, Volume 35, Issue 7, July 2026.
Abstract FAD/NAD(P)H‐dependent dehydrogenases form a structurally conserved family of redox enzymes that participate in essential metabolic processes across parasites and higher organisms. Among them, trypanothione reductase (TR) is a key component of the redox metabolism of Leishmania species and represents an attractive target for antileishmanial ...

Time‐ and cultivar‐dependent biochemical responses to heat priming and stress in rice

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Global warming increasingly threatens rice productivity, and understanding the biochemical mechanisms underlying heat stress responses is crucial for developing resilient cultivars. By demonstrating that stress responses are both cultivar‐ and time‐of‐day‐dependent, our findings offer new insights into the temporal and genetic regulation of acquired ...

Putative involvement of lncRNA, miRNA, and mRNA‐mediated ceRNA network regulation in drought priming to enhance drought tolerance in Nicotiana tabacum

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Drought priming increased the tolerance of Nicotiana tabacum to severe, recurring drought stress by modulating the expression of stress‐related genes via long non‐coding RNAs (lncRNAs), which acted as competing endogenous RNAs (ceRNAs) for microRNAs (miRNAs) and messenger RNAs (mRNAs).
