Redox regulation of ascorbate and glutathione by a chloroplastic dehydroascorbate reductase is required for high-light stress tolerance in Arabidopsis

open access: yes, 2016
Chloroplasts are a significant site for reactive oxygen species production under illumination and, thus, possess a well-organized antioxidant system involving ascorbate.

MsWRKY49 Modulates Pollen Tube Elongation in Response to Boron Deficiency by Regulating Reactive Oxygen Species Homeostasis in Alfalfa

open access: yesPlant Biotechnology Journal, Volume 24, Issue 2, Page 856-870, February 2026.
ABSTRACT Boron, an essential micronutrient, plays a crucial role in plant reproductive processes. Boron deficiency is widespread in many regions and significantly reduces alfalfa (Medicago sativa) seed yield, yet the molecular mechanisms underlying its impact on reproductive organ development remain elusive.

Cloning, expression, and characterization of an enzyme possessing both glutaredoxin and dehydroascorbate reductase activity from taiwanofungus camphorata

open access: yes, 2009
[[abstract]]Glutaredoxins (Grxs) play important roles in the reduction of disulfides via reduced glutathione as a reductant. A cDNA (503 bp, EU 193660) encoding a putative Grx was cloned from Taiwanofugus camphorata (Tc).

Cold hardiness in Ostrinia nubilalis (Lepidoptera: Pyralidae): Glycerol content, hexose monophosphate shunt activity, and antioxidative defense system

open access: yesEuropean Journal of Entomology, 2004
Many insects in temperate regions overwinter in diapause, during which they are cold hardy. In these insects, one of the metabolic adaptations to the unfavorable environmental conditions is the synthesis of cryoprotectants/anhydroprotectants.

Proteomic analysis of dehydroascorbate reductase transgenic potato plants

open access: yesJournal of Plant Biotechnology, 2016
Ascorbic acid (AsA) is a strong antioxidant/reducing agent that can be converted to dehydroascorbate (DHA) by oxidation in plants. DHA, a very short-lived chemical, is recycled to AsA by dehydroascorbate reductase (DHAR). Previously, DHAR cDNA was isolated from the hairy roots of the sesame plant, and DHAR-overexpressing transgenic potato plants were ...

Multi‐Level Approaches for Assessing Molecular and Physiological Traits of Drought and Heat Stress Tolerance in Plant Reproductive Development

open access: yesPhysiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Abiotic stress, particularly heat and drought, significantly impacts plant reproductive development, threatening crop productivity and food security. Understanding stress tolerance mechanisms requires a multi‐level approach that integrates physiological, biochemical, and molecular traits in different experimental settings. This review explores

Diphenyl diselenide in its selenol form has dehydroascorbate reductase and glutathione S-transferase-like activity dependent on the glutathione content

open access: yes, 2010
Objectives The antioxidant action of diphenyl diselenide ((PhSe)2) is attributed to the mechanism by which (PhSe)2 has pharmacological activity.

Olive Response to Salinity: A Comprehensive Review to Causes, Mechanisms, and Management

open access: yesAdvances in Agriculture, Volume 2026, Issue 1, 2026.
Water is the most limiting resource in the Mediterranean region. Fresh water availability is one of the major restraints for agricultural development worldwide. So, the usage and adoption of poor‐quality water, including salty water and wastewater is becoming an important issue in sustainable horticulture.

Structural Insights into the Dehydroascorbate Reductase Activity of Human Omega-Class Glutathione Transferases

open access: yes, 2016
The reduction of dehydroascorbate (DHA) to ascorbic acid (AA) is a vital cellular function. The omega-class glutathione transferases (GSTs) catalyze several reductive reactions in cellular biochemistry, including DHA reduction.

Effect of cadmium on antioxidative enzymes, glutathione content, and glutathionylation in tall fescue

open access: yesBiologia Plantarum, 2014
The aim of this work was to assess the effect of different Cd2+concentrations on some antioxidant enzymes in Festuca arundinacea. Increased activities of ascorbate peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase, glutathione S ...
