Therefore, it could be concluded that, this review will basically cover Se physiology and biology in higher plants. Plant Se essentiality, uptake and bioavailability, metabolism, toxicity and biogeochemistry also well be reviewed. Selenium and its relationship with sulfur and effects of elemental nano-Se on higher plants will be highlighted.
