Several million hectares of economically cultivated transgenic crops are currently available. There have been field trials of transgenics from at least 200 species, oil plants (including both annual and perennial) belonging to different plant families. Crops that produce oil seeds are crucial to the agricultural economy. They have a significant role in industrial uses and the human diet, but they are also becoming more significant as a fossil fuel replacement for supplying energy. A number of significant developments in genetic engineering and the identification of gene targets for increasing seed oil content in oilseed crops have occurred during the past 20 years. These developments will help the successful development of new generation high yielding oil crops. A significant portion of the most recent data comes from the examination of patent databases, an excellent source of data on commercial priorities. The timeline for the introduction of these transgenes into breeding populations and their eventual release as novel varieties is also covered in the review.

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.
