“…On the contrary, several pteridophytes (ferns) are known to be particular accumulators of REEs. Strong positive concentration anomalies of La and Ce were reported in at least 9 species of the genera Dryopteris, Asplenium, Adiantum and Dicranopteris in a Japanese study comprising 96 species of ferns (Ozaki et al, 2000). Leaf mesophyll tissue contained 10-40 µg g −1 dry weight of La and 3-30 µg g −1 of Ce in the accumulators, compared to 0.003-2.7 and 0.076-3.6 µg g −1 , respectively, in the other species studied.…”

The rare earth elements (REEs) form a chemically uniform group and include yttrium (Y), lanthanum (La) and the lanthanides cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu). Their average abundance in the Earth's crust range from 66 µg g −1 in Ce to 0.5 µg g −1 in Tm and 0.1 µg g −1 in Pm. Recent great improvements in more routine analytical technique, the use of REEs as fertilisers, at least in East Asian agriculture, and the importance of these elements as indicators in both pedological and physiological processes and reactions have contributed to an increased interest in these previously less considered elements in environmental sciences. This review of recent and current literature deals with REEs in primary and secondary soil minerals, concentrations in surface soils, factors influencing adsorption, solubility and transport in soils, including weathering and transformations of REE minerals, and vertical distribution in soil profiles. Reviewed and discussed are also concentrations, distribution and localisation of REEs in plants and plant organs, soil-plant relationships and interactions, effects on plant growth and crop production and their importance in plant physiology and biochemistry. The REEs are found, usually several elements together, as phosphates, carbonates and silicate minerals finely dispersed especially in magmatic and metamorphic rocks. REE concentrations in surface soils of humid climates, such as the A(E)-horizons of Podzols and Laterites, are usually lower than in the parent material, due to higher weathering and leaching rates than of the average soil constituents. Some fractionation may occur due to the formation of more element-specific secondary minerals. Transfer from soil to plant is usually low, but extreme accumulators are found, e.g., among several species of ferns. Roots have generally higher concentrations than shoots. Possible uptake mechanisms of REEs are discussed. Uptake is positively, though often weakly, correlated with soil acidity and easily soluble concentrations of the elements, but rarely well related to their total concentrations in the soil. Under certain conditions, low concentrations of at least some REEs seem to favour plant growth and productivity, but the physiological mechanisms are still not well understood. Some considerations concerning the boundary between essential and non-essential micro nutrients are discussed.

“…However, it has been reported that Dryopteris erythrosora contain up to 30 μg g −1 (0.2 μmol g −1 ) of Ce in leaves, which is a factor 10 to 100 higher than in non-accumulator ferns from the same place (Ozaki et al, 2000). Another fern, Dicranopteris dichotoma (synonymous with D. linearis) has the highest concentrations of total REs (and Ce) in leaves ever reported for a vascular plant thus far (Ichihashi et al, 1992;Wang et al, 1997).…”

Aim of the study: The effect of cerium oxide engineered nanoparticles on the spore germination of the fern Asplenium adiantumnigrum.Area of study: France, Britanny Region, Finistére Department, Plougonvelin, in rocks near the sea. Material and methods: Asplenium spores were cultured in vitro on agar medium with Nano-CeO 2 (less than 25 nm particle size) and bulk-CeO 2 . The addition of each nano-and bulk particles ranged from 0 to 3000 mg L -1 . Observations on rhizoidal and prothallial cells during first stages of gametophyte development were made. The No-Observed-Adverse-Effect concentration (NOAEC) and Lowest-Observed-Adverse-Effect-Concentration (LOEC) values for spore germination rate data were analyzed.Main results: Germination was speeded up by 100 to 2000 mg L -1 nanoceria, while bulk cerium oxide had the same effect for 500 to 2000 mg L -1 concentrations. Present results showed cellular damage in the protonema while rhizoid cells seemed not to be affected, as growth and membrane integrity remained.Research highlights: Both nanosized and bulk cerium oxide are toxic for the fern Asplenium adiantum-nigrum, although diverse toxicity patterns were shown for both materials. Diverse toxic effects have been observed: chloroplast membrane damage and lysis, cell wall and membrane disruption which leads to cell lysis; and alterations in morphology and development.
