Exogenous kinetin mitigates arsenic-induced oxidative stress by regulating ROS homeostasis and antioxidant defense in Ocimum basilicum L.

Nickel-induced biphasic regulation of morpho-physiological, biochemical, and essential oil traits in drought-stressed Fumaria parviflora Lam.

Nickel (Ni) acts as an essential micronutrient at low concentrations but induces toxicity when accumulated excessively. Drought stress likewise restricts plant growth and secondary metabolism in medicinal plants. This study investigated the single and interactive effects of foliar-applied Ni and drought stress on growt...

Phytoprotectants in Action: Shielding Plants from Oxidative Damage under Thermal Extremes and Flooding Stress

Waterlogging (WL) and extreme temperatures are major abiotic stresses that threaten agricultural productivity. High and low temperatures impair photosynthesis, reduce enzyme activity and destabilize membranes, whereas WL causes hypoxia, nutrient imbalance and metabolic disorder. Both stresses lead to excessive build-up...

Antioxidant Defense Mechanism in Plants Under Salt Stress: Physiological, Biochemical and Molecular Insights

critical insights are provided into these interdependent responses in plants to understand how they contribute to enhancing stress tolerance and improving crop productivity, which will be highly valuable for developing strategies to optimize plant responses under rising salinity levels and, consequently, improve crop y...

Fulvic acid and hydrogen sulfide synergistically mitigate chromium stress in tobacco seedlings by regulating oxidative stress indicators and antioxidant defense mechanisms.

Melatonin Attenuates Cadmium-Induced Oxidative Stress in Potato by Remodeling Redox Homeostasis and Activating Multi-Pathway Antioxidant Networks

Cadmium pollution severely suppresses potato growth, impairs photosynthesis, and disrupts cellular redox balance, threatening crop yield and food safety. Exogenous small-molecule regulators represent low-cost strategies to alleviate heavy-metal phytotoxicity, yet systematic comparisons of N-acetyl-L-cysteine (NAC), L-t...

Pyrogallol aggravates arsenic toxicity in Triticum aestivum L. through oxidative stress and mineral imbalance

Pyrogallol (PG), a plant-derived phenolic compound, exhibits dual redox behaviour as either an antioxidant or pro-oxidant depending on cellular context; however, its interaction with metal and metalloid stress remains poorly understood. This study investigated whether exogenous PG amplifies arsenic-induced oxidative st...
