Summary
This narrative review synthesises current knowledge of the mechanisms by which certain plant species hyperaccumulate selenium, integrating molecular, biochemical and ecological perspectives. The authors examine uptake pathways, metabolic transformations, detoxification strategies and ecological drivers of selenium hyperaccumulation, as suggested by the 2018 literature. The work contributes to understanding both fundamental plant physiology and practical applications for phytoremediation and biofortification.
UK applicability
The mechanistic insights may be relevant to UK research on crop biofortification and phytoremediation strategies, though selenium hyperaccumulator plants are not native to the UK and selenium status in British soils is generally low. The findings could inform future biofortification programmes or remediation of contaminated sites.
Key measures
Molecular and biochemical pathways involved in selenium uptake, translocation, metabolism and tolerance; ecological factors influencing hyperaccumulation capacity
Outcomes reported
This survey synthesises current understanding of the molecular, biochemical and ecological mechanisms underlying selenium hyperaccumulation in plants. The study examines how certain plant species accumulate selenium to concentrations far exceeding those in soil or non-accumulating plants.
