Role of Antioxidant Enzymes and Glutathione S-Transferase in Bromoxynil Herbicide Stress Tolerance in Wheat Plants.

Background: Numerous pesticides and herbicides used in excess cause oxidative stress in plants. These chemicals protect plants from weeds and pests, but they also have very negative side effects, making them common abiotic stressors. One of the most significant nutritional crops in the world is the wheat plant.

Exogenous melatonin-mediated regulation of K /Na transport, H -ATPase activity and enzymatic antioxidative defence operate through endogenous hydrogen sulphide signalling in NaCl-stressed tomato seedling roots.

Melatonin (Mel) and hydrogen sulphide (H S) have emerged as potential regulators of plant metabolism during abiotic stress. Presence of excess NaCl in the soil is one of the main causes of reduced crop productivity worldwide. The present investigation examines the role of exogenous Mel and endogenous H S in tomato seedlings grown under NaCl stress.

Hydrogen sulfide (HS) and potassium (K) synergistically induce drought stress tolerance through regulation of H-ATPase activity, sugar metabolism, and antioxidative defense in tomato seedlings.

Exogenous potassium (K) and endogenous hydrogen sulfide (HS) synergistically alleviate drought stress through regulating H-ATPase activity, sugar metabolism and redox homoeostasis in tomato seedlings. Present work evaluates the role of K in the regulation of endogenous HS signaling in modulating the tolerance of tomato (Solanum lycopersicum L. Mill.

Evaluation of the genetic diversity of wild Salvadora persica 'Arak' from Saudi Arabia.

Assessment of genetic diversity is crucial for efficient selection genotypes in plant breeding and improvement programs. Studies of genetic diversity of S. persica are rare relative to the large species diversity in Saudi Arabia, despite its valuable importance as one of the most popular medicinal plants.

Traffic and industrial activities around Riyadh cause the accumulation of heavy metals in legumes: A case study.

The objective of this study was to analyse the effect of the continuously increasing anthropogenic activities around Riyadh, Saudi Arabia on the accumulation of heavy metals in leguminous crops. This study determined whether four legume crops, Pisum sativum L., Vicia faba L.
