Abstract: Abiotic stressors are the main barriers to successful crop production in this era. The balance of redox and metabolic activities in plants is negatively impacted by abiotic stresses, which ultimately limit the plants' capacity to grow and develop. The phytohormones are tiny molecules that control how plants grow and develop, as well as how they react to alterations in their environment. Phytohormone, gibberellic acid (GA) has been proven in a number of recent research to increase plants' ability to withstand abiotic stress. By regulating numerous physio-biochemical and molecular processes, GA plays a crucial part in reducing the perturbations caused by abiotic stresses in plants. Recent findings have shown that GA controls the activity of antioxidant enzymes, stress-responsive genes, photosynthetic machinery, and reduced oxidative damage. Besides, GA has been involved in cross-talk with other phytohormones to regulate abiotic stress in plants. This review summarises the current research on the application of GA and discusses how GA might support crop growth and production in adverse conditions. The interaction of GA with other phytohormones, potential mechanisms for reducing abiotic stress in plants, the disadvantages of employing GA, and its promise for the future are also covered in this review.
