Oxidative stress in wild‐derived and cultivated peanut genotypes caused by heat stress at flowering

Agronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract Peanut (Arachis hypogaea L.) is a globally important crop; however, its productivity is increasingly threatened by heat stress, exacerbated by global warming. Developing heat‐tolerant peanuts is crucial for sustainable production amidst rising temperatures.

Cytosolic Monodehydroascorbate Reductase 2 Promotes Oxidative Stress Signaling in Arabidopsis

Plant, Cell & Environment
ABSTRACTThe antioxidative enzyme monodehydroascorbate reductase (MDHAR) is represented by five genes in Arabidopsis, including four that encode cytosolic and peroxisomal proteins. The in planta importance of these specific isoforms during oxidative stress remain to be characterised.

Molecular cloning and characterization of a cDNA encoding pea monodehydroascorbate reductase.

Journal of Biological Chemistry, 1994
Monodehydroascorbate radicals are generated in plant cells enzymatically by the hydrogen peroxide scavenging enzyme, ascorbate peroxidase, and nonenzymatically via the univalent oxidation of ascorbate by superoxide, hydroxyl, and various organic radicals. Regeneration of ascorbate is achieved by monodehydroascorbate reductase (EC 1.6.5.4) using NAD(P)H

Adaptive Remodeling of the Proteome in Pistachio Roots Under Salt Stress: Implications for Food and Energy Security in Arid Regions

Food and Energy Security, Volume 14, Issue 6, November/December 2025.
Overview of evaluating the effects of NaCl treatment on pistachio rootstock UCB‐1. ABSTRACT Pistachio thrives in semi‐arid and arid environments and is highly adaptable to various abiotic stresses. However, soil salinization significantly threatens productivity, leading to considerable osmotic and ionic stress for these plants.

Properties of Monodehydroascorbate Reductase and Dehydroascorbate Reductase and Their Participation in the Regeneration of Ascorbate in Euglena gracilis [PDF]

Microbiology, 1987
The partially purified monodehydroascorbate reductase (EC 1.6.5.4) from Euglena gracilis Z showed a pH optimum of 7.0 and a temperature optimum of 41 °C, and had an M r of 52000. Activity was threefold higher with N ADPH than with N ADH; the K m values for N ADPH and NADH were 7 and 210 μm, respectively.

Phytoglobin Scavenging of Nitric Oxide Is Associated With Ethylene Reduction and Drought Tolerance in Oat (Avena sativa)

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Drought stress significantly impacts crop productivity and plant physiology. Nitric oxide (NO) signalling is essential for drought tolerance. This study explores the relationship between in vivo NO levels, mediated by NO scavenging phytoglobin (encoded by Pgb, non‐symbiosis associated hemoglobin), and drought tolerance in oat (Avena sativa ...
