“…A higher pH value was related to a generally lower phytoextraction of REEs, which suggests that the studied herbaceous plant species could be able to uptake these elements more effectively in the case of more acidic soils. It is worth underlining that a small change in the pH of soil may be related with significant differences in REE phytoextraction, as described by Wiche et al ( 2016 ). The authors have shown that phytoextraction of La and Nd was significantly higher in herbs than in grasses and REEs are more effectively accumulated in slightly acidic than slightly alkaline soils.…”

Rare earth elements (REEs) are a group of elements whose concentration in numerous environmental matrices continues to increase; therefore, the use of biological methods for their removal from soil would seem to be a safe and reasonable approach. The aim of this study was to estimate the phytoextraction efficiency and distribution of light and heavy (LREEs and HREEs) rare earth elements by three herbaceous plant species: Artemisia vulgaris L., Taraxacum officinale F.H. Wigg. and Trifolium repens L., growing at a distance of 1, 10, and 25 m from the edge of a frequented road in Poland. The concentration of REEs in soil and plants was highly correlated (r > 0.9300), which indicates the high potential of the studied plant species to phytoextraction of these elements. The largest proportion of REEs was from the group of LREEs, whereas HREEs comprised only an inconsiderable portion of the REEs group. The dominant elements in the group of LREEs were Nd and Ce, while Er was dominant in the HREEs group. Differences in the amounts of these elements influenced the total concentration of LREEs, HREEs, and finally REEs and their quantities which decreased with distance from the road. According to the Friedman rank sum test, significant differences in REEs concentration, mainly between A. vulgaris L., and T. repens L. were observed for plants growing at all three distances from the road. The same relation between A. vulgaris L. and T. officinale was observed. The efficiency of LREEs and REEs phytoextraction in the whole biomass of plants growing at all distances from the road was A. vulgaris L. > T. officinale L. > T. repens L. For HREEs, the same relationship was recorded only for plants growing at the distance 1 m from the road. Bioconcentration factor (BCF) values for LREEs and HREEs were respectively higher and lower than 1 for all studied plant species regardless of the distance from the road. The studied herbaceous plant species were able to effectively phytoextract LREEs only (BCF > 1); therefore, these plants, which are commonly present near roads, could be a useful tool for removing this group of REEs from contaminated soil.

“…The modified availability of these elements arising from soil pH could explain the correlations observed between REEs and essential elements. Wiche et al (2016) observed an increase in Fe, Mn and P content, as well as REEs, in barley and white lupine (Wiche et al 2016). The authors suggested that these elements could result from the dissolution of REE-phosphates, carbonates and Fe-Mn oxyhydroxides under the influence of root exudates (Wiche et al 2016).…”

The authors suggested that these elements could result from the dissolution of REE-phosphates, carbonates and Fe-Mn oxyhydroxides under the influence of root exudates (Wiche et al 2016). This hypothesis was confirmed by Shan et al (2002), who demonstrated that the bioavailability of REEs in soil is affected by soil pH and by low molecular weight organic acids (Shan et al 2002).…”

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.

“…El uso de lupino blanco en cultivos mixtos permite aumentar al doble la absorción de P en trigo, comparado a trigo en monocultivo (Horst y Waschkies, 1987). La absorción de otros nutrientes como el Fe y el Mn también se ve afectada en cultivos mixtos (Wiche et al, 2016).…”

The roots are the plant organs responsible for water and nutrient absorption which are needed for adequate plant growth. Therefore, it is important to know both the extent and distribution of the root system into the soil since it determines the ability of the plant for mining soil resources, especially in poor soils or soils with low nutrient or water availability. The present work describes the root system of different crops and their relationships with the shoot, and how it determines the efficiency for nutrient uptake. On the other side, we review some morphological adaptations of the root system that improve the absorption of nutrients. This work also describes how the renewal of the root system occurs in a growing season and how it changes or adapts depending on environmental stress factors affecting the plants.
