The Role of Reactive Oxygen Species and Calcium Ions in Implementing the Stress-Protective Effect of γ-Aminobutyric Acid on Wheat Seedlings Under Heat Stress Conditions
γ-aminobutyric acid (GABA) is considered a molecule that combines the properties of a stress metabolite and a signaling molecule. At the same time, the importance of its functional interaction with other signa...

Redox homeostasis of cereals during acclimation to drought
Abiotic stresses are responsible for nearly 90% of all yield losses, around 40% of which are due to drought. Most cereal crops, the mainstay of agricultural production in many countries, are sensitive to droug...
