“…The elevated concentrations of TEs adversely change the nuclei ultrastructure, which causes the nuclear envelope destruction or nucleus volume reduction, chromatin condensation, chromosomal aberrations, and nucleic acids damage, resulting in decreased cell mitotic and transcriptional activity [34,54,55]. In turn, the disruption of plasma membrane integrity was ascertained, among others, in Erythrina fusca [32] or Lemna gibba [56] under Cu, Cr, and Cd stress, whereas malformations of the cell walls were found in Brassica napus cultivars that were treated with Cr [52] or Co ions [57].…”

Heavy metals are an interesting group of trace elements (TEs). Some of them are minutely required for normal plant growth and development, while others have unknown biological actions. They may cause injury when they are applied in an elevated concentration, regardless of the importance for the plant functioning. On the other hand, their application may help to alleviate various abiotic stresses. In this review, both the deleterious and beneficial effects of metallic trace elements from their uptake by roots and leaves, through toxicity, up to the regulation of physiological and molecular mechanisms that are associated with plant protection against stress conditions have been briefly discussed. We have highlighted the involvement of metallic ions in mitigating oxidative stress by the activation of various antioxidant enzymes and emphasized the phenomenon of low-dose stimulation that is caused by non-essential, potentially poisonous elements called hormesis, which is recently one of the most studied issues. Finally, we have described the evolutionary consequences of long-term exposure to metallic elements, resulting in the development of unique assemblages of vegetation, classified as metallophytes, which constitute excellent model systems for research on metal accumulation and tolerance. Taken together, the paper can provide a novel insight into the toxicity concept, since both dose- and genotype-dependent response to the presence of metallic trace elements has been comprehensively explained.

“…S. polyrhiza, a monocotyledonous free-floating named giant duckweed, is widely distributed throughout the world, and represents the largest duckweed (1.5 cm long) with the smallest genome size (158 Mb) among all duckweeds measured [41]. Moreover, the genome of S. polyrhiza has been estimated, and the annotation has been further refined, thus providing a convenient model for molecular research [41][42][43][44], including the molecular mechanism studies of metal ion resorption and excretion [45][46][47][48][49][50].…”

Natural resistance-associated macrophage proteins (Nramps) are specific metal transporters in plants with different functions among various species. The evolutionary and functional information of the Nramp gene family in Spirodela polyrhiza has not been previously reported in detail. To identify the Nramp genes in S. polyrhiza, we performed genome-wide identification, characterization, classification, and cis-elements analysis among 22 species with 138 amino acid sequences. We also conducted chromosomal localization and analyzed the synteny relationship, promoter, subcellular localization, and expression patterns in S. polyrhiza. β-Glucuronidase staining indicated that SpNramp1 and SpNramp3 mainly accumulated in the root and joint between mother and daughter frond. Moreover, SpNramp1 was also widely displayed in the frond. SpNramp2 was intensively distributed in the root and frond. Quantitative real-time PCR results proved that the SpNramp gene expression level was influenced by Cd stress, especially in response to Fe or Mn deficiency. The study provides detailed information on the SpNramp gene family and their distribution and expression, laying a beneficial foundation for functional research.

“…All Cr and Mn estimations were based on three replicates (Bokhari et al, 2016; Chaudhary & Sharma, 2019; Dahmani‐Muller et al, 2000; Vajpayee et al, 2000). Statistical analysis comprised one‐way analysis of variance (ANOVA) (microcosm df = 3, 8; mesocosm df = 5, 12) with least square difference (LSD) test at p < 0.05 using SPSS 20 for Windows.…”

Phytoremediation of chromium and manganese by Ipomoea aquatica Forssk. from aqueous medium containing chromium‐manganese mixtures in microcosms and mesocosms

Ipomoea aquatica—an aquatic macrophyte—could remove chromium and manganese from their mixtures after 96 h exposure at a maximum rate of 82.8% and 93.9%, respectively, in microcosms. The removal rates were higher (90.4% and 94.5%, respectively) after 96 h exposure in mesocosms with gravel beds and vertical subsurface flow. The higher removal rates in mesocosm were probably due to a wide range of partitioned micro‐environments close to the root boundaries, and within the biofilms on both root and gravel surfaces. The Cr and Mn removal efficiencies of I. aquatica increased with increasing Cr or Mn concentrations in the medium. The study reveals the potential of I. aquatica—a fast‐growing species that can proliferate by fragmentation—to effectively remove Cr and Mn within a relatively short period of time, thereby raising the prospect of its use in phytoremediation of wastewater contaminated with these metals.
