Improving selenium status in plant nutrition and quality

Selenium (Se) is an essential micronutrient for human health due to its antioxidant capabilities. The Se content around the world is highly variable from 0.005 mg kg-1 in areas from China and Finland to 8,000 mg kg-1 in seleniferous soils fromTuva-Russia. However, about one billion of people in the...

The Se content around the world is highly variable from 0.005 mg kg-1 in areas from China and Finland to 8,000 mg kg-1 in seleniferous soils fromTuva-Russia.

During the last decade, studies related with strategies for Se biofortification in food plants for human nutrition have significantly increased because this metalloid is incorporated into human metabolism mainly as a constituent of food plants.

Agronomic biofortification by using inorganic Se sources is a current practice in countries as China, Finland, and USA.
