“…The complexation with ligands may reduce the cell wall adsorption and phosphate precipitation. There is a geochemical plant-root barrier; the lower concentrations of REE in soils favor the greater uptake of this group of elements by plants and vice versa (Zhenggui et al, 2001). The same relationship was noted in two radish species, cultivated Raphanus sativus and wild R. raphanistrum that took up higher amounts of REE from the illite substrate than from the smectite equivalent even though the latter contained three times more REE (Semhi et al, 2009b, Table 2).…”

“…In vascular plants, the highest REE concentrations were noted in roots and leaves, but the uptake and translocation depended on plant species (Li et al, 1998;Wyttenbach et al, 1998aWyttenbach et al, , 1998b. The study conducted by Zhenggui et al (2001) revealed variations of REE concentrations in different parts of naturally grown fern D. linearis at five sampling sites in the South-Jiangxi region (Southern China). For example, the concentrations of total REE were in the range of 134-1754 mg/kg (root), 107-633 mg/kg (stem), 51-102 mg/kg (petiole) and 977-2271 mg/kg (lamina).…”

The increasing number of rare earth elements (REEs) studies in the past decade has been induced by their wider applications in industry, including electronics and high technology. This review presents the brief characteristics of REE, their occurrence in abiotic and biotic systems, and their possible detrimental effects on the environmental quality and human health. This also outlines the REE behavior in different geochemical interactions and the potential for tracing anthropogenic pollution sources.

“…The two species of fern that have the greatest capacity for REE accumulation are particularly interesting. Pronephrium simplex can accumulate up to 1200 mg kg -1 (Lai et al 2005(Lai et al , 2006, while Dicranopteris dichotoma can contain up to 3300 mg kg -1 (Ozaki et al 1997;Wei et al 2001;Shan et al 2003). It has been suggested that high concentrations of REEs in ferns may help these species adapt better to changing environments (Liu et al 2017).…”

Identification of new hardy ferns that preferentially accumulate light rare earth elements: a conserved trait within fern species

et al. 2020

Environmental contextRare earth elements (REEs) are strategic metals and emerging contaminants for which plant-based remediation measures are needed. We screened a collection of hardy ferns and identified new accumulator species that preferentially transferred light REEs to their fronds. This study is an important step towards understanding the mechanisms of REE accumulation in plants. AbstractRare earth elements (REEs) include the lanthanides plus yttrium and scandium, and can be split according to their atomic mass into light (LREEs) and heavy REEs (HREEs). The increasing demand for REEs is mainly driven by new technologies, and their current low recyclability has led them to become emerging contaminants. The identification of new REE accumulators may help in determining the REE transfer mechanisms and may result in interesting candidates for phytoremediation techniques. To that end, a collection of 49 hardy fern species, grown in REE-spiked substrate, were screened for their potential in REE accumulation. REE concentrations were very low in the fronds of all Polypodium species, whereas all Athyrium species highly accumulated REEs. The REE accumulation level was more variable among the different species of Dryopteris, Blechnum, Woodwardia, Cystopteris and Polystichum. However, whatever the species, LREEs were preferentially transferred to the fronds over HREEs. This conserved trait was independent of the availability of different REEs in the substrate and instead may arise from specific transfer systems in ferns for the two groups of REEs. Furthermore, REE accumulation was correlated to Ca and Al, which suggested the existence of common uptake pathways. Altogether, these results are of great interest for phytoremediation purposes since appropriate species can be chosen according to the area to be remediated, and they also provide new insights into a more in-depth characterisation of the underlying REE accumulation mechanisms in ferns.

“…The readers may be referred to the works of Evans [36], Cantrell and Byrne [37], Millero [38], Tao et al [39], among many others. The enrichment in LREEs in the plants studied here can be explained as resulting from high concentrations of low-molecular organic ligands, such as citrates, malates and oxalates, in the rhizosphere solutions [40][41][42], whereas the enrichment in HREEs could result from their complexation with intrinsic chelators in the xylem.…”

Two species of radishes, Raphanus sativus and Raphanus raphanistrum, were grown in the laboratory in the same substrate consisting of a smectite-type clay, which was watered at the beginning of the experience with 50 ml of a solution containing either none or 1000, 2000 or 4000 mg/L of AgNO 3 , respectively. Occurrence of the toxic metal in the substrate outlines higher element uptakes by the cultivated species Raphanus sativus than by the wild species Raphanus raphanistrum, except for the highest degree of Ag pollution. After a one-month growth in the Ag-polluted substrate, Raphanus sativus was depleted in most of the major, trace and rare-earth elements, except for Al, Fe, Th, Ag and U that increased in the radishes from substrate polluted by 2000 mg/L of AgNO 3 , and Sr, Co, Ni, U and Ag that increased in the radishes from substrate polluted by 4000 mg/L of AgNO 3 . Raphanus raphanistrum was enriched in all elements except Si, Na, Rb and K in the polluted substrate. The uptake was monitored by a cation-exchange process in the rhyzosphere between mineral particles and the watering solution in the presence of various enzymes with specific activities that induced a variable uptake with the REEs being even fractionated. These activities most probably depend on combined factors, such as the plant species, and the chemical and physical properties of the substrate. The results obtained here reveal also that accumulation of nutrient elements and others in the plants is not uniform at a given Ag pollution of the substrate and therefore at a given Ag contamination in the same plant species.
