“…The latter corresponds to M. polymorpha sensu stricto [ 23 ], i.e., the taxon in which nuclear and organellar genomes have been entirely sequenced [ 24 ]. M. polymorpha has a high capacity for acquiring metals and may therefore provide a valuable tool for metal biomonitoring [ 26 , 27 ]. For all these reasons, in-depth investigations on M. polymorpha PCS can provide relevant information on functional aspects of this enzyme in plants and allow useful comparisons with the cyanobacterial PCS.…”

This paper reports functional studies on the enzyme phytochelatin synthase in the liverwort Marchantia polymorpha and the cyanobacterium Geitlerinema sp. strain PCC 7407. In vitro activity assays in control samples (cadmium-untreated) showed that phytochelatin synthase was constitutively expressed in both organisms. In the presence of 100 µM cadmium, in both the liverwort and the cyanobacterium, the enzyme was promptly activated in vitro, and produced phytochelatins up to the oligomer PC4. Likewise, in vivo exposure to 10–36 µM cadmium for 6-120 h induced in both organisms phytochelatin synthesis up to PC4. Furthermore, the glutathione (GSH) levels in M. polymorpha were constitutively low (compared with the average content in higher plants), but increased considerably under cadmium stress. Conversely, the GSH levels in Geitlerinema sp. PCC 7407 were constitutively high, but were halved under metal treatments. At odds with former papers, our results demonstrate that, as in M. polymorpha and other plants, the cyanobacterial phytochelatin synthase exposed to cadmium possesses manifest transpeptidasic activity, being able to synthesize phytochelatins with a degree of oligomerization higher than PC2. Therefore, prokaryotic and eukaryotic phytochelatin synthases differ less in functional terms than previously thought.

“…Heavy metal deposition is one of the most serious aspects of air pollution. Due to the high toxicity and persistence in the environment, heavy metals have a direct and serious impact on human health [6][7][8]. In this context, several studies documented that heavy metals, for example, cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) are among the most toxic air pollutants.…”

We evaluated heavy metal deposition in Parmotrema arnoldii and Tillandsia usneoides in response to air pollution in Loja city, Ecuador. We assessed heavy metal (cadmium, copper, manganese, lead and zinc) content in these organisms at nine study sites inside Loja city and three control sites in nearby forests. Concentrations of all studied heavy metals (i.e., cadmium (Cd), copper (Cu), lead (Pb), manganese (Mn) and zinc (Zn)) were highest in downtown Loja. Our study confirms that passive monitoring using lichens and/or bromeliads can be an efficient tool to evaluate heavy metal deposition related to urbanization (e.g., vehicle emissions). We recommend these organisms to be used in cost-effective monitoring of air pollution in tropical countries.

“…We found higher concentrations of four heavy metals (Al, Cu, Fe, and Zn) in M. polymorpha in city zones, which indicated its ability to bioaccumulate toxic elements. Thus, this species can be used as an effective biomonitor of heavy metal pollution [12]. Our study adds M. polymorpha to the list of suitable species for this task.…”

“…Elemental bioaccumulation was studied in the subcosmopolitic thallose liverwort Marchantia polymorpha L. We chose this species because it has proved elsewhere to be an effective bioaccumulator of heavy metals [12,13,32]. To sample M. polymorpha, we took four samples (0.5-1 g) of the species in the same sites (two separate sites by zone), where bryophytes frequency and cover were sampled at each of the four study zones.…”

“…Bryophytes are well-known bioaccumulators of toxic elements due to its eco-physiology (i.e., rapid absorption and slow desorption of pollutants [10][11][12]), and morphology (bryophytes lack of epidermis that allows them to accumulate toxins present in water [13,14]). Recent studies have shown that some bryophyte species living in contaminated rivers, like the thallose liverwort Marchantia polymorpha L., can be enriched by heavy metals like Cu, Zn, and Cd [12,13]. Moreover, bryophyte community structure can also respond to natural and anthropogenic variability throughout a river's profile.…”

Aquatic and rheophilous bryophytes can indicate water pollution as they bioaccumulate toxic water elements. We evaluated (1) bioaccumulation of eight heavy metals and arsenic by Marchantia polymorpha L., and (2) changes in bryophyte community structure, as responses to urban pollution in southern Ecuador. To this end, we registered presence/absence and coverage of submerged bryophytes in 120 quadrats across three zones of the Zamora river inside Loja city, and a control zone in a nearby forest. We found that the concentrations of five (Al, Cd, Cu, Fe, and Zn) of the eight chemical elements and arsenic were highest in urban M. polymorpha. Moreover, bryophyte species richness decreased in urban zones. Bryophyte community structure also differed between control and city zones, but no differences were found among city zones. The control zone was composed by a more distinct set of bryophyte species, e.g., an indicator species analysis showed that 16 species had high and significant indicator values for control zone, but only 11 species were indicators of at least one of the three urban zones. We concluded that bryophytes, in general, and M. polymorpha, in particular, can be suitable biomonitors of water quality in tropical urban rivers.
