Abstract
Selenium (Se) is a trace element that is widely available around the world and is vital for living things. Although it is an essential micronutrient for many living things, it causes serious toxicity, especially when taken in large quantities. Plants are the primary source of Se for humans and animals. The essentiality of Se for plants is controversial, but low amounts of Se are required to protect plants from various abiotic stresses such as cold, drought, desiccation, and metal stress. However, due to the accumulation of various toxic forms or nonspecific replacement of it with sulfur analogues, it damages plants by changing protein structures and by disrupting many metabolic pathways, which causes oxidative/nitrosative stress. In addition, Se acts as both as an antioxidant and a pro-oxidant depending on its amount in plants. In this chapter, it is aimed to evaluate the Se metabolism in plants with omics approaches. © 2023 John Wiley & Sons Ltd.
