Rare Earth Elements (REEs) Recovery and Hydrochar Production from Hyperaccumulators
… and sustainable methods for treating REE hyperaccumulators, aimed at enhancing REE recovery and obtaining value-added byproducts. Firstly, grass seeds fed with a solution containing Y, La, Ce, and Dy, were found to have the capacity to accumulate around 510 mg/kg (dry basis) of total rare …

Characterisation of putative metal transport proteins in the nickel hyperaccumulator Senecio coronatus: investigating candidate genes for nickel tolerance and accumulation
… in this area has been performed on zinc/cadmium hyperaccumulators and comparatively little is known about the molecular mechanisms behind nickel accumulation. This is despite the fact that nickel hyperaccumulators constitute more than 75% of all known hyperaccumulator species. One such species is …

The Ecology and Evolution of Rare, Soil Specialist Astragalus Plants in the Arid Western U.S.
… in the greenhouse. Both non-accumulators and hyperaccumulators had less herbivory with increasing selenium concentrations, and also grew larger, despite the energetic cost of selenium uptake. One potential explanation for their larger growth is that selenium reduced inadvertent drought stress …

Interplay between selenium hyperaccumulator plants and their microbiome
… diverse endophytic microbial communities as non-hyperaccumulators. Thus, plant Se does not impair associations with microbes. A variety of microbes have been isolated from plants or soil in seleniferous areas, including some bacteria and fungi with extreme Se tolerance. Inoculation of plants with …

Phytoremediation of Sembrong River waters using neptunia oleracea and pistia stratiotes
… of Al and Fe. However, the plants were not hyperaccumulators of Zn. Using photomicrography transverse sections of plant tissues cultivated in river water showed toxic symptoms like distortion, increase in the number of layers of cells and damages. The control plants did not exhibit any …

The role of Iron Regulated 2 and Iron Regulated Transporter 1 in nickel hyperaccumulation traits in Senecio coronatus
… Ni hyperaccumulation despite the fact that Ni hyperaccumulators account for almost three quarters of all known hyperaccumulating species. A comparative RNA-Seq experiment carried out on Ni accumulating and non-accumulating populations of the South African Ni hyperaccumulator Senecio coronatus …

Adaptability, Biomass Yield, and Phytoremediation of Arundo donax L. on marginal lands: salt, dry and lead-contaminated soils
… yields. Although the Arundo plants are not hyperaccumulators, high phytoextraction yields can be achieved in contaminated soils, due to a conjugation of phytotolerance and high yields. This allows us to consider that Arundo can be more efficient than certain hyperaccumulator plants but with …

CHARACTERIZATION OF TWO METAL TRANSPORTERS HMA3 AND NRAMP1 IN TWO ECOTYPES OF THE ZN/CD HYPERACCUMULATOR THLASPI CAERULESCENS COMPARED WITH ARABIDOPSIS THALIANA
Accumulation of a given metal in plants depends on a delicate and precise balance of various biological processes. Some plants have developed strategies that allow them to tolerate heavy metals in extreme conditions without suffering toxicity. This research focuses on the characterization of two …
