Abstract
Selenium (Se) is an important mineral element for both plants and animals. It is also referred to as a useful poison because although it plays numerous beneficial roles in the plant development and growth but high Se concentrations can also lead to toxicity in plants. Plants absorb Se in the form of selenite and selenate from the soil and eventually assimilate it in their plastids. This chapter discusses in detail the uptake, transportation, assimilation, metabolism and toxicity of Se in plants. The various biochemical pathways of Se accumulation and assimilation have been thoroughly discussed. It also highlights the various positive and negative effects of Se in plants giving special attention to the role of Se in combating various abiotic stresses like drought, salinity, heavy metals, extreme temperatures, and ultraviolet radiation.
