Accumulation of Pb and Zn in Gametophytes and Sporophytes of the Moss Funaria hygrometrica(Funariales)

Antioxidant activity in extracts fromLeptodictyum riparium(Bryophyta), stressed by heavy metals, heat shock, and salinity

“…A voucher specimen was deposited at the Herbarium of the Department. Plant samples were stressed for 24 h with Pb (NO 3 ) 2 at 10 75 M, CdCl 2 at 10 75 M, 458C, 200 mMol NaCl and cultured as reported elsewhere (Basile et al 2001). …”

“…via enzymatic and non-enzymatic antioxidative systems such as glutathione, vitamins C and E, and hydroquinones), and it is known that levels of total glutathione and glutathione reductase activities increase with increasing metal uptake or other environmental stresses (Bargagli 1998). While a lot of studies are available on tissue and cell localisation of heavy metals in plants, and in particular in bryophytes, (Basile et al 1990;1994;2001;Sorbo et al 2008) only scarce data are available on antioxidant activity in extracts from Bryophyta exposed to heavy metals (Ielpo et al 1998). Research on Pleurochaete squarrosa showed an increase in antioxidant activity of acetonic extract in moss stressed by heavy metals, salinity, and heat shock (Vuotto et al 2002).…”

Application and Comparison of Two Biotic Ligand Models Predicting Copper Toxicity and Accumulation in Heavy Metal Tolerant Moss

“…However, n of F. hygrometrica was much higher than that of lettuce root, indicating that F. hygrometrica has higher potential to accumulate copper. Basile et al also suggested that F. hygrometrica has high potential to accumulate zinc and lead (Basile et al, 2001).…”

Introductory Chapter: Serious Pollution of Soil and Groundwater and the Necessity of Bioremediation

“…The advantages of mosses are: (1) they can cover the ground completely without disturbing the flow of rain water, (2) they can grow at a faster rate with little water, and (3) they have advantages in the reuse of metals because they can accumulate metals at high concentrations. In fact, Scopelophia cataractae and Funaria hygrometrica that are known as hyperaccumulators of metals could accumulate copper and lead at very high levels [47,48].…”
