“…Glime (2021) suggested that bryophyte cuticles could prevent the absorption of pollutants, thus playing a protective role. This has been supported by Elvira et al (2020), demonstrating that lipophilic, wax-like substances deposited on the surface of the moss Ptychostomum capillare retained a significant amount of Cu-containing particles. In addition, the pollutant phenanthrene was retained and accumulated within the cuticular matrix for more than 10 days until it entered the cell cytoplasm (Wu et al, 2014).…”

“…Such characteristics make these plants valuable for phytoremediation in mining areas for mitigating environmental pollution. In cases where soil pollution is not too high, Ptychostomum capillare was able to absorb Cu, according to research done on biomonitoring of PTE contamination in a former Cu mine in Central Spain (Elvira et al 2020). Petrović et al (2021) conducted a study in Bor, Serbia, an area known for Cu mining and discovered that sun spurge (Euphorbia helioscopia L.) had the highest concentration of each metal compared to other plants, particularly Cu.…”

With a substantial rise in both domestic and worldwide copper mining rates over the past decade, Iran has become a major producer of copper in the Middle East. The increasing need for copper-based products in a variety of industries, including as information technology, electronics, transportation, and construction, is driving this rise. However, the expansion of copper mining activities has led to environmental degradation, particularly in mining sites where potentially hazardous elements (PTEs) have contaminated the soil. Despite these significant environmental impacts, they have often been overlooked, posing long-term environmental challenges as copper extraction continues. This research extensively reviews the literature (from 2000 to 2023) on soil contamination in Iran’s copper mining districts, focusing on PTEs. It evaluates the extent of potentially hazardous elements’ pollution in soils, comparing findings with global data, and explores remediation strategies employed in these regions. Results suggest that studies predominantly center around the Sarcheshmeh copper mine, highlighting copper, lead, and molybdenum as dominant PTE pollutants. Phytoremediation emerges as the primary remediation method used in these areas, indicating Iran's sustainable approach to addressing potentially hazardous elements’ contamination. This review recommends comprehensive monitoring of PTEs across all Iranian copper mines and further exploration of native plant species that successfully grow and stabilize potentially hazardous elements grow in copper mining areas remediation.

“…Most of what is presently known about their tolerance mechanisms comes from biochemical and physiological studies. Mechanisms such as retention of heavy me-tals in extracellular wax-like substances 62 , sequestration in the cell wall [63][64][65][66] , preferential accumulation in specific parts/organs of the leafy plant -i.e. gametophore [67][68][69] , or the activation of the ROS scavenging machinery and induction of metal-chelating proteins 70 , have been reported to mitigate heavy metal stress in bryophytes.…”

Bryophytes’ remarkable capacity to tolerate extreme abiotic conditions allows us to enhance our understanding of the diversity of molecular mechanisms involved in plant stress response. Here, we used next generation sequencing to study DNA methylation and gene expression changes in plants from four populations of the metallophyte moss Scopelophila cataractae experimentally exposed to either Cd or Cu. These populations previously showed differences in tolerance to both metals, so here, we aimed at uncovering the molecular basis of this phenotypic differentiation. We found no evidence of genetic differentiation among the populations studied. The epigenetic data, however, showed limited but significant population-specific changes in DNA methylation in response to both metals. Exposure to acute Cu stress in the laboratory led to the downregulation of genes involved in heavy metal tolerance in both populations regardless of their tolerance level, but this response was quantitatively higher in the most tolerant. We propose that chronic exposure to varying levels of heavy metals in the field led to potentially non-genetically-based intraspecific differentiation for heavy metal tolerance in S. cataractae. The most tolerant plants invested more in constitutive protection and were more efficient in entering a conservative state when faced with acute Cu stress.
