Zinc Oxide Nanoparticles in Alleviation of Toxicity Induced by Heat Stress in Plants

Abstract

Climate change-related abiotic pressures have an impact on plant development and yield, which decreases the amount of food produced. High temperature (HT) stress has a large worldwide impact on plant development, metabolism, and productivity. The growth and development of plants involves numerous temperature-sensitive metabolic processes. The widespread practices of producing crops in polluted surroundings is currently environmentalists' top worry. So, in order to maintain high crop yields under HT stress, which is currently a key worry for crop production, it is vital for agriculture to develop various strategies. A current relevant technology for enhancing food production and ensuring sustainability in the pursuit of food safety is highly developed nanotechnology. Nanotechnology boosts agricultural productivity by improving input effectiveness and reducing relevant losses. This review looks at earlier studies that show how zinc oxide nanoparticles (ZnO-NPs) can mitigate the negative effects of heat stress. ZnO-NPs application is the most effective method available globally to greatly boost agricultural output in challenging settings. With the aid of a number of cutting-edge technologies for reversing the symptoms of oxidative stress brought on by heat stress, ZnO-NPs can revolutionize the agricultural and food industries. The impact of ZnO-NPs on the physiological, antioxidative and biochemical activities in different plants has also been thoroughly studied. This review summarizes the current understanding and future perspectives of plant-ZnO-NPs research.
