Elucidating the mechanisms of uptake and translocation of rare earth elements in Blechnopsis orientalis (2026)

Rare earth elements (REE) hyperaccumulators reported are few, and the mechanisms of the uptake are poorly understood. Blechnopsis orientalis was recently discovered as a REE hyperaccumulator (up to 3850 mg/kg total REEs in Australia). This fern is widely distributed in subtropical areas, including Australia. This experiment aims to elucidate REE uptake and translocation mechanisms in Blechnopsis orientalis. This knowledge is fundamental to advancing its potential use in the development of phytomining for the recovery of REEs from low-grade sources.
