This paper tested if culturing the moss Scorpiurum circinatum (Brid.) Fleisch. & Loeske with metal solutions (Cd, Cu, Pb and Zn) for 30 days causes metal bioaccumulation and ultrastructural changes. The results showed that despite the high heavy metal concentrations in treatment solutions, treated samples did not show severe ultrastructural changes and cells were still alive and generally well preserved. Bioaccumulation highlighted that moss cells survived to heavy metal toxicity by… Expand
Uptake and acute toxicity of cerium in the lichen Xanthoria parietina.
TLDR
Treatment with Ce solutions induces Ce bioaccumulation, which in turn causes an acute toxicity, evident as decreased sample viability, marked decrease in the photosynthetic performance and important changes in the ultrastructure. Expand
Phytofiltration of chosen metals by aquarium liverwort (Monosoleum tenerum).
TLDR
Overall, the bryophyte M. tenerum demonstrate high potential for the removal of toxic metals from the multi-metal solution via accumulation in plant tissue, which was proper to indicate the use of M. Tenerum for phytofiltration of waste waters affected by Zn, Cu, Ni, Mn and Fe. Expand
In-field and in-vitro study of the moss Leptodictyum riparium as bioindicator of toxic metal pollution in the aquatic environment: Ultrastructural damage, oxidative stress and HSP70 induction
TLDR
The results showed that L. riparium is a valuable bioindicator for toxic metal pollution of water ecosystem, accumulating different amounts of toxic metals from the aquatic environment, and GST and HSP70s as promising biomarkers of metal toxicity. Expand
Effects of heavy metals on ultrastructure and Hsp70 induction in Lemna minor L. exposed to water along the Sarno River, Italy.
TLDR
Results presented showed that copper specifically increased Hsp70 levels at concentrations detected in polluted river waters, whereas cadmium and lead did not; on the other side, the latter represent highly toxic elements when specimens were exposed to higher levels in vitro. Expand
Limited accumulation of copper in heavy metal adapted mosses.
TLDR
The role of the copper-linked anion and applied copper as CuCl2, CuSO4 and CuEDTA, respectively is investigated and the relation between metal accumulation and ROS production using indicator dyes in the three moss species is discussed. Expand
ALLEVIATION OF LEAD STRESS TOXICITY IN VIGNA UNGUICULATA BY SALICYLIC ACID
TLDR
It is suggested that SA antagonizes the oxidat ive damaging effects of Pb not only di rect ly through act ivat ing the ant antioxidant system such as catalase, peroxidase and ascorbate, but also indirect ly through lowering the uptake of PB from soi l . Expand
Assessing the effects of heavy metal contamination on the proteome of the moss Pseudoscleropodium purum cross-transplanted between different areas
TLDR
Although the proteins identified were associated with moss metabolism, the expected growth reduction in samples autotransplanted within POLL (as a result of the down-regulation of photosynthesis-related proteins), did not occur, and supports the hypothesis that mosses growing in polluted areas adapt to heavy metal pollution and are able to reduce/overcome their toxic effects.

Ecophysiological and ultrastructural effects of dust pollution in lichens exposed around a cement plant (SW Slovakia)
TLDR
Results showed that dust deposition from quarrying activities and cement works at the cement mill significantly affected the photosynthetic apparatus of E. prunastri (sensitive to dust and habitat eutrophication), while X. parietina adapted to the new environment. Expand
The Moss Leptodictyum riparium Counteracts Severe Cadmium Stress by Activation of Glutathione Transferase and Phytochelatin Synthase, but Slightly by Phytochelatins
In the present work, we investigated the response to Cd in Leptodictyum riparium, a cosmopolitan moss (Bryophyta) that can accumulate higher amounts of metals than other plants, even angiosperms,Expand
Responses to Cadmium in Early-Diverging Streptophytes (Charophytes and Bryophytes): Current Views and Potential Applications
TLDR
This review will deal with different mechanisms that charophytes and bryophytes have evolved to respond to Cd at a cellular level, focusing on specific mechanisms that help achieve detoxification. Expand

Ultrastructural Responses of the LichenBryoria fuscescensto Simulated Acid Rain and Heavy Metal Deposition
TLDR
The results suggest that acid wet deposition containing metal ions may reduce survival of lichens in northern environments and an ameliorating interaction between the metals and acidity is suggested. Expand
Heavy metal deposition in the Italian "triangle of death" determined with the moss Scorpiurum circinatum.
TLDR
Although severe biological effects were not found at the ultrastructural level in the exposed moss, effects on humans, especially after long-term exposure, are to be expected. Expand

Biochemical responses of the aquatic moss Fontinalis antipyretica to Cd, Cu, Pb and Zn determined by chlorophyll fluorescence and protein levels
TLDR
Results on protein level after heavy metal stress in the aquatic bioindicator moss are provided for the first time, and it is shown that Cu is chelated in the cytoplasm by SH-groups and coprecipitated with orthophosphate in vacuoles. Expand
Uptake of minerals, particularly metals, by epiphytic Hypnum cupressiforme
TLDR
Comparisons with other Scandinavian investigations on heavy metal contents in epigeic moss were made, and it was concluded that the metal contents of epiphytic moss originate mainly from the atmosphere. Expand
Accumulation of Pb and Zn in Gametophytes and Sporophytes of the Moss Funaria hygrometrica (Funariales)
TLDR
The role performed by the gametophyte and the placenta in the accumulation and sequestration of Pb and Zn was investigated in the moss Funaria hygrometrica Hedw collected from mine tailings. Expand

Uptake of heavy metal salt solutions by pollen grains of Magnolia × soulangeana (Magnoliaceae)
TLDR
Ulastructural analysis revealed differences in the labelling of the pollen grains with the time of exposure to the heavy metal salt, which is likely related to metal tolerance mechanisms operating in the pollen grain. Expand

TLDR
Both young and mature submerged leaves of Elodea canadensis treated for 1 month with 100 μM Cd added to the growth water medium showed a decreased photosynthetic activity, not only ascribable to lowered chlorophyll contents. Expand
