“…Cr-treated samples of T. barbuloides accumulated excess H 2 O 2 in correlation with suppressed POX activity. Data are accordant with the results of declined POX activity in the bryophyte Taxithelium nepalense in 1 mM Cr (Choudhury and Panda, 2005) and Taxiphyllum taxirameum in 100 µM short-term Cr exposure (Chen et al, 2015). The discrepancy in POX activity in moss species indicates that different enzymatic (CAT, APX) and nonenzymatic ROS scavengers operate in the elimination of H 2 O 2 from cells.…”

“…These results can be attributed to the variability of the reactive potential of metals and species. Toxic effects of Cu and Cr on total chlorophyll were also registered for terrestrial moss Taxiphyllum taxirameum (Chen et al, 2015) and other mosses (Shakya et al, 2008). Chl and Car contents of P. squarrosa decreased slightly upon Ni and Pb exposure; similar data have also been reported in moss species Hypnum plumaeforme after 48 h of Ni and Pb exposure (Sun et al, 2009).…”

“…For example, they indirectly decrease net photosynthesis and transpiration in plants by causing a disturbance in the stomatal structure [42]. HMs directly disturb the structure of thylakoid membranes at chloroplast and photosynthetic proteins, which mainly damage the efficiency photochemistry parameters in the dark-adapted state (fv/fn) and PSII [43], and reduce energy transfers to the reaction centre [44].…”

Nowadays, the contaminations generated by anthropogenic activities have had damaging effects on the life cycle of plants, particularly on the plants living in the vicinity of urban areas that are more associated with the life of people. Bamboo, as a local plant, is one of the most widely used plants in China. So, a pot experiment was conducted to investigate the effects of three HMs (Cu, Pb, and Zn) in four different concentrations (0 (for control), 500 mg/kg, 1000 mg/kg, and 200 mg/kg), with complete randomized design (CRD) by five replications for each treatment to measure the antioxidant enzymes, lipid per oxidation (LP), soluble protein (SP), gas exchange parameters, and morphological indexes in Sasa kongosanensis f. aureostriatus. The results indicated that the antioxidant responses had an arc-shaped trend with various alterations in which POD and CAT first increase with low concentration of HMs (500 mg/kg) and then decrease with the increase of heavy metal (1000 mg/kg and 2000 mg/kg). Additionally, measuring of MDA content and soluble protein illustrated that MDA content and soluble protein increase with excess of HMs in different levels, and also the excess of HMs significantly decreases the photosynthesis properties. Moreover, the results obtained by morphological indices showed that low concentration of HMs increases both percentage of shoot length and percentage of emerge plants at all three kinds of HMs, but observe a downward trend with excess of heavy metal in 1000 mg/kg and 2000 mg/kg. Overall, in "Sasa kongosanensis f. aureo -striatus, results indicated that low concentration of HMs (500 mg/kg) can help the plant growth, while excess of HMs (1000-2000 mg/kg) alleviates the plant growth. On the other hand, Pb revealed the lowest antioxidant

“…The treatment with EDTA, a well-known chelating agent, useful to decrease metal concentrations in field mosses and to increase their cation exchange capability before the exposure (e.g. Lodenius and Tulisalo, 1984;Ferreira et al, 2009;Chen et al, 2015;Iodice et al, 2016), had no evident effect on the clone elemental composition, likely in virtue of the already very low element concentrations in the biomaterial. On the other hand, the EDTA washing added Na and induced morphological damages to the moss clone, making its shoots and leaves very fragile (see SEM micrographs in Fig.…”

a b s t r a c tThis work aimed to define the molecular and chemical signature of a S. palustre clone developed in the framework of the EU-FP7 Mossclone project to improve the standardization and reliability of the mossbag technique. The molecular characterization was performed by a set of DNA molecular markers (RAPD, ISJ, PCR-RFLP, sequencing and microsatellites) to tag the clone produced within the project. Molecular characterization also provided new DNA markers that can be applied in systematic analyses of Sphagnum, and gave new insights to implement well established techniques. The elemental composition of the clone was measured by ICP-MS analysis of 54 major and trace elements, with and without commonly applied pre-exposure treatments (oven devitalization and EDTA washing). Concentrations of almost all analyzed elements were significantly lower (from 10 to 100 times) in the clone than in conspecific field moss, apart from some elements (K, Mo, P and Na) deriving from the culture medium or EDTA treatment. Oven devitalization and EDTA washing did not significantly affect the clone composition. A comparison between the elemental composition of the clone with that of naturally growing Sphagnum species proved the particularly low elemental content of the clone. Therefore, in view of a rigorously standardized moss-bag protocol for the monitoring of persistent atmospheric pollutants, the use of the S. palustre clone, a biomaterial with very low and constant element composition, and homogenous morphological characteristics is strongly recommended.
