Abstract
Plant production today depends on the ability of agriculturists to transport and recycle minerals, particularly those minerals which are nutritionally important to animals and human beings, through various agriculture products. It is important to note that the attenuation of these mineral deposits by green plants, as well as their subsequent role in the production of organic compounds, is fundamental to almost all known forms of life. Selenium (Se) is among those trace mineral which are crucial for the maintenance of plant physiology. The significance, production, and biological effects of this element, as well as its application in sustainable development, are remaining an interesting topic of discussion. Moreover, there has been a huge rise in the potential applications of nanotechnology in the food and agriculture industries. Several studies have been conducted on the various biological activities of selenium nanoparticles (SeNPs) and their biosynthesis. There is plenty of research performed on the effects of Se in plant nutrition and physiology, but there is a lack of information about the effects of SeNPs in SeNPs toxicity, and other aspects of using SeNPs in agriculture. The current review is focused on recent information related to the effects and fate of SeNPs in agronomy. We also aimed attention at the primary sources and behavior of Se in different environments, such as soil, water, air, and plants. All the data provides an extremely fertile domain for future investigation and research.
Highlights
Selenium (Se) is a common trace metalloid found in the Earth’s crust
Plants can benefit from the use of selenium nanoparticles (SeNPs) in a variety of applications, including (1) the controlled release of agrochemicals and their distribution to increase the effectiveness of the products used, (2) the handle of pests and illnesses triggered by infectious microbes such as bacteria and fungi, (3) as quasi-essential trace nutrients, via promoting plant biochemical pathways, and so refining crop progress, yield, and nutritional worth, (4) biofortifying harvests using Se to upsurge their content, (5) alleviating abiotic stress, and (6) increasing the nutraceutical quality of consumable foods [35]
Several agricultural and horticultural uses exist for Se; some of these include using it in the form of SeNPs and sodium selenite, as well as selenate
Summary
Selenium (Se) is a common trace metalloid found in the Earth’s crust. In 1817, chemist Jacob Berzelius isolated it for the first time, and since it has been known for its properties [1]. Se may work as an essential factor by interfering with a several of physiological processes [2] It is a remarkable antioxidant and pro-oxidant agent of plants that helps to cope with a variety of abiotic stresses, such as salinity, drought, intense temperature fluctuations, toxic metals/metalloids, and other environmental pollutants and toxins [3]. Se helps to reduce an accumulation of free radicals or reactive oxygen species (ROS) and prevents an oxidative stress. Because there is limited available information about the risks associated with handling NPs, such as selenium nanoparticles (SeNPs), they have obtained a heightened interest in their uses in agriculture and in-plant nutrition via ultra-small scales. The current review is based on the fate of SeNPs in the plant-production agronomic sector with respect to environment, plant nutrition, and agronomy
