ABSTRACT
Biofortification is used to enhance the contents of minerals/vitamins in agricultural crops, providing enriched food to the population. While genetic biofortification comprises the selection of varieties with a greater potential for nutrient uptake, agronomic biofortification relies on fertilization strategies to provide extra nutrients to plants. This approach is relevant in tropical regions of the world, were most soils are nutrient-depleted (Lopes & Guilherme 2016). Selenium (Se) has many benefits in plant metabolism, yet it is not essential for crops. Still, due to its importance for humans and animals, Se is one of the target elements of biofortification programs.
