“…The seedlings with GUS reporter gene were incubated at 37°C in GUS staining solution (0.5 mM potassium ferricyanide, 0.5 mM potassium ferrocyanide, 10 mM EDTA, and 1 mg/ml 5-bromo-chloro-3-indolyl-b- D -glucuronide in 50 mM sodium phosphate buffer, pH 7.0) for 3–5 h ( Liu et al, 2016 ). The GUS staining was quantified in the root tips using ImageJ software.…”

“…Lanthanum (La) is an important rare earth element (REE) and has been used as a crop growth stimulants for appropriately 50 years ( Hu et al, 2004 ; Xie et al, 2013 ; Liu et al, 2016 ). La affects many aspects of plant growth and development and stress tolerance, including the changes in photosynthesis efficiency, mineral nutrient uptake capacity, antioxidative enzyme activities, and phytohormonal balance ( He et al, 2005 ; Ruíz-Herrera et al, 2012 ; Wang et al, 2012 ; Xie et al, 2013 ; Liu et al, 2016 ). Although low concentration of La improves crop production, high concentration of La represses crop growth.…”

“… Wang et al (2014) found that La-activated endocytosis might play a role in La-mediated growth and development in plants. Our previous study found that high concentration of La (≥80 μM) significantly inhibits primary root (PR) growth whereas it markedly induces LR development, and thereby regulates RSA ( Liu et al, 2016 ). However, the physiological and molecular mechanisms underlying La-mediated RSA remain largely unclear.…”

“…PIN2 mediates root gravitropism ( Müller et al, 1998 ) and auxin redistribution in roots response to iron (Fe) stress ( Li et al, 2015 ). PIN4 mediates meristematic activity and auxin redistribution in roots response to biological nitrification inhibitor methyl 3-(4-hydroxyphenyl) propionate (MHPP) ( Liu et al, 2016 ). PIN7 mediates early embryo development ( Friml et al, 2003 ) and auxin redistribution in roots response to manganese (Mn) toxicity ( Zhao et al, 2017 ).…”

“… Yuan and Huang (2016) demonstrated that cadmium (Cd) toxicity reduced auxin level in PR tips by repressing PIN1/3/7 accumulation and increasing IAA17 stabilization. Our previous study indicated that, although La induced the expression of auxin biosynthesis-related genes, it markedly reduced auxin accumulation in PR tips ( Liu et al, 2016 ). However, whether and how La regulates root system growth and development by regulating auxin transport in roots remains unclear.…”

Lanthanum (La) is one of rare earth elements that was used as a crop growth stimulants; however, high concentration of La markedly inhibited plant growth. Our previous study indicated that, although La induced the expression of auxin biosynthesis-related genes, it markedly repressed primary root (PR) elongation by reducing auxin accumulation in PR tips. In this study, we exhibited that La reduces the abundances of auxin carriers. Treatment with La markedly inhibited the auxins IAA-, 2,4-D-, and NAA-induced elevation of DR5:GUS activity in the roots, suggesting that La inhibited auxin transport through both the influx and efflux transporters. Supplementation with auxin transport inhibitor naphthylphthalamic acid in La-treated seedlings did not further reduce PR growth compared with that of the La treatment alone, further confirmed that auxin transport is involved in La-induced inhibition of PR growth. Analysis of the protein abundances using the transgenic AUX1-YFP and PIN1/2/4/7-GFP marker lines indicated that La treatment reduced the abundances of all these auxin carriers in the PR tips. La also increased the stabilization of Aux/IAA protein AXR3. Taken together, these results indicated that La treatment inhibits PIN-mediated auxin transport and subsequently impairs auxin distribution and PR growth via reducing auxin carrier abundances.

Rare earth elements (REEs) are key constituents of modern technology and play important roles in various chemical and industrial applications. They also are increasingly used in agricultural and zootechnical applications, such as fertilizers and feed additives. Early applications of REEs in agriculture have originated in China over the past several decades with the objective of increasing crop productivity and improving livestock yield (e.g., egg production or piglet growth). Outside China, REE agricultural or zootechnical uses are not currently practiced. A number of peer-reviewed manuscripts have evaluated the adverse and the positive effects of some light REEs (lanthanum and cerium salts) or REE mixtures both in plant growth and in livestock yield. This information was never systematically evaluated from the growing body of scientific literature. The present review was designed to evaluate the available evidence for adverse and/or positive effects of REE exposures in plant and animal biota and the cellular/molecular evidence for the REE-associated effects. The overall information points to shifts from toxic to favorable effects in plant systems at lower REE concentrations (possibly suggesting hormesis). The available evidence for REE use as feed additives may suggest positive outcomes at certain doses but requires further investigations before extending this use for zootechnical purposes.
