“…The concentrations of Mn in the pinnae of D. linearis (1480 ± 523 mg kg −1 ; Table 1) are much greater than what is typically toxic in most of the plants (e.g., <200 mg kg −1 in maize or 275 ± 659 mg kg −1 in various species of naturally grown ferns). 36,37 Therefore, the necrosis in these tissues is possibly, among other reasons, the result of Mn accumulation, oxidation, and localized toxicity within the pinnules, which then induces cell death, necrotic spots, substantially larger necrotic lesion, and then finally acts as a "dump site" for REEs as a result of cell damage, higher evaporation rate, and transpiration flow. A similar phenomenon has been reported in the leaves of soybean and cowpea in response to Mn toxicity; the toxicity started with Mn pumped under the cuticle via the apoplast or Mn is expelled via hydathodes toward the leaf tip, and then, increasing concentrations of Mn leads to Mn oxidation (+2 to +3 and +4 valences) and the formation of necrotic lesions, which in turn stimulate more Mn translocation as a result of higher evaporation.…”

The fern Dicranopteris linearis (Gleicheniaceae) from China is a hyperaccumulator of Rare Earth Elements (REEs), but little is known about its ecophysiology in relation to REEs. This study aimed to clarify tissue-tissue and organ-level distribution of REEs via synchrotronbased X-ray fluorescence microscopy (XFM).• The results show that La + Ce are mainly co-localized with Mn in the pinnae and pinnules, with the highest concentrations in necrotic tissues.• In the cross-sections of the pinnules, midveins, petioles and stolons La + Ce and Mn are enriched in the epidermis, vascular bundles, and pericycle (midvein). In these tissues, Mn is localised mainly in the cortex and mesophyll compared to La + Ce in these cross-sections.• We hypothesize that REEs transpiration flow in the veins is initially restricted by the pericycle between vascular bundle and cortex, whilst excess REEs are transported by evaporation and co-compartmentalized with Mn in the necrotic tissues and epidermis in an immobile form, possibly an Si-coprecipitate.

“…From TRY, we extracted the leaf Na, Ca, and Mg contents per leaf dry mass (Trait IDs 260, 252, and 257, respectively) for plant species previously documented as sika deer food in Japan [27]. The final dataset included 3179 values for 191 plant species (Table S1) from five original publications [28][29][30][31][32]. The leaf mineral content data were averaged for each species, and the averaged values were used for further analysis.…”

Deficient minerals in overabundant populations could act as an attractant to cull sika deer (Cervus nippon). Because selective culling of female deer is reported to be effective in reducing sika deer populations, it is particularly important to clarify the differences in mineral requirements between male and female. Here, using global plant trait data and a published list of sika deer food plants in Japan, we estimated whether food plants provide sika deer sufficient sodium (Na), calcium (Ca), and magnesium (Mg), and compared the results between male and female. An analysis of 191 food plant species suggested that food plants can provide sufficient Mg, whereas sufficient Na and Ca is not always provided, especially when the intake is small or the deer large. Na deficiency was more intense for lactating females than males, suggesting that Na can be an effective attractant for selectively culling female deer. In summary, this study demonstrated that sika deer in Japan might require extra Na and Ca sources in addition to food plants, and therefore these minerals could be useful for developing effective culling methods.

“…Previous studies have indicated that the Al-accumulators can accumulate high amount of Al in the roots and the above ground organs (Jansen et al 2003;Olivares et al 2009;Metali et al 2012;Osawa et al 2013;Schmitt et al 2017). It has been suggested that the nontoxic Al complexes may transport into the root via symplast and the above ground organs either through xylem or phloem pathway (Zeng et al 2013;Schmitt et al 2016b;Wang et al 2017).…”

The aim of this research was to investigate the effect of aluminum (Al) on the plant growth, nutrient uptake, and Al accumulation in Camellia japonica. A hydroponic experiment was performed in a completely randomized design with four concentration of Al (0, 0.5, 1, and 2 mM). After growing 8 weeks in the hydroponic nutrient solution, the fine roots and mature leaves of plants were sampled to analyze the biomass, photosynthetic parameters, nutrients uptake, and Al accumulation. The 0.5, 1, and 2 mM Al supplement presented an increase of 71, 118, and 42% on the root biomass, respectively, comparing to the control. The Alinduced growth stimulation in 0.5 and 1 mM Al treatment of Camellia japonica was associated with increased levels of chlorophyll a and b, promotion of net photosynthesis rate, raised contents of soluble sugar and total soluble protein, and decreased levels of malondialdehyde (MDA) and free proline in both leaves and fine roots. The concentrations of nitrogen (N), phosphorus (P), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) in fine roots of 1 mM Al-treated plants were significantly higher than those in the control plants, whereas the levels of calcium (Ca) and magnesium (Mg) were much lower. The mean Al levels in the 1 mM Al-treated plants were 1587, 7189, and 11,192 mg kg −1 (dry mass, DW) for the 1st/2nd, 3rd/4th mature leaves, and fine roots, respectively. This study indicated that 0.5 and 1 mM Al were beneficial to the growth of Camellia japonica. This Alinduced growth enhancement was presumably associated with the increased uptake of nutrient elements. This study also confirmed Camellia japonica as an Al-accumulator.
