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

Physiologia 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

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

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.

Ex vitro acclimatization of plantain plantlets micropropagated in temporary immersion bioreactor

Biologia Plantarum, 2010
Plantain (Musa ABB CEMSA 3/4) plantlets were micropropagated in temporary immersion bioreactors (TIB) or in gelled medium (GM). After ex vitro transfer ROS accumulation was determined by infiltrating leaves with nitroblue tetrazolium (NBT) and 3,3 ...

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.

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 ...
