“…Low concentrations of REEs may accelerate nutrient element's uptake, improve photosynthesis, and stimulate plant growth [1,[14][15][16], while higher concentrations of REEs may reduce the uptake of nutrient elements and inhibit the development and growth of plants [17][18][19]. It is thus evident that REEs can lead to the unbalance of mineral nutrients and thereby interfere with plant growth.…”

Effects of lanthanum (La) on mineral nutrients, cell cycles, and root lengthening have been little reported. The present work investigated these physiological responses in roots of Vicia faba seedlings cultivated in La3+-contained solutions for 15 days. The results showed that the increasing contents of La in the roots and leaves contributed to disbalances of contents of Ca, Fe, Cu, Zn, Mg, Mn, P, and K elements, and potential redistributions of some elements in the roots and leaves. These disbalances might be involved in the subsequent alteration of cell cycle phases in the root tips. Low-dose promotion and high-dose inhibition (Hormetic effects) were demonstrated as the dose responses of G0/G1-, S- or G2/M-phase ratios. The cell cycles were most probably arrested at G1/S interphase by La3+ in the root tips. The fact that the root lengths were not consistent with the changes of cell cycle phases suggested that the cell proliferation activities might be masked by other factors (e.g., cell expansion) under long-time exposure to La3+.

“…Maize root elongation (but not dry matter production) increased about two-fold at an application of Ce 3+ , 0.088 mg L −1 (Diatloff et al, 1995b). Root growth of coconut palm in pot culture was favoured by La 3+ , Pr 3+ and Nd 3+ at low rates of application (Wahid et al, 2000).…”

Rare earth elements in soil and plant systems - A review

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.

“…Recent studies of YLOID in plant-soil systems, have often focused on several main aspect of metabolic mechanism (Johnson & Barton, 2007;Ouyang, Wang, Zhao, Yuan, & Wang, 2003), as well as of their distribution among plant organs of whole individual plant, and between an individual plant and the soil in which the plant grew (Bibak, Stürup, Knudsen, & Gundersen, 1999;Brioschi et al, 2013;Wahid et al, 2000;Xu, Zhu, Wang, & Witkamp, 2002).…”
