This indicates the essential nature of these micronutrients in plants. Although Se promotes optimal growth in unicellular green alga, its roles in higher plants are debated.Molecular Plant Abiotic Stressdoi:10.1002/9781119463665.ch7Aditya Banerjee
Selenium (Se) is an essential micronutrient for humans, animals and some lower plants at very low concentrations, whereas it is extremely toxic at higher doses. Furthermore, living organisms become exposed to high Se concentrations via both anthropogenic

potential, converting selinium into forms unavailable for plant uptake. This is also pronounced in soils with increased nitrate deposition which converts the selenate and selenite into elemental selenium or its gaseous form. On the other hand, winter forage is seen to contain higher amounts of ...

roots. Plants absorb Se from the environment mainly via the roots. Selenite absorbed into the roots will be transported to various parts of the plant, but the selenite retained in the roots was higher than those transported to other parts, so the Se content in the roots was generally higher...
whereas it is rarely found in elemental form (Se0). While there is no evidence of Se need for higher plants, several reports show that when Se added at low concentrations, Se exerts beneficial effects on plant growth. Se may act as quasi-essential micronutrient through altering different physi...
it is important to note that Se can also be detrimental in excessive amounts, and contamination of the environment due to Se from agricultural and industrial sources has resulted in catastrophic ecological disasters over the past half-century. Consequently, the utilization of Se-enriched plants for...
