“…Moreover, as observed in the present study, longer treatments generally lead to the downregulation of these proteins. An explanation for the lack of sustainable variations observed in our long-term study could be the possible presence of protection mechanisms, preventing persistent damage to the genome in the presence of chronic exposure (Irfan et al 2013). Phytochelatins or metallothionein proteins could be involved in tolerance mechanisms such as chelation and sequestration processes (Clemens 2006).…”

The present study was designed to investigate the combined effects of Cd and Pb on accumulation and genotoxic potential in white clover (Trifolium repens). For this purpose, T. repens was exposed to contaminated soils (2.5-20 mg kg(-1) cadmium (Cd), 250-2000 mg kg(-1) lead (Pb) and a mixture of these two heavy metals) for 3, 10 and 56 days. The resulting bioaccumulation of Cd and Pb, DNA damage (comet assay) and peroxidase activities (APOX and GPOX) were determined. The exposure time is a determinant factor in experiments designed to measure the influence of heavy metal contamination. The accumulation of Cd or Pb resulting from exposure to the two-metal mixture does not appear to depend significantly on whether the white clover is exposed to soil containing one heavy metal or both. However, when T. repens is exposed to a Cd/Pb mixture, the percentage of DNA damage is lower than when the plant is exposed to monometallic Cd. DNA damage is close to that observed in the case of monometallic Pb exposure. Peroxidase activity cannot be associated with DNA damage under these experimental conditions.

“…Cadmium also causes various direct and indirect effects on plant growth and metabolism (Hasan et al, 2009) by forming complexes with O, N and S ligands (Van Assche and Clijsters, 1990). It interferes with protein metabolism,membrane functioning and water relations (Irfan et al, 2013). Cadmium inhibited net photosynthesis in Cajanus cajan (Sheoran et al, 1990) and Phaseolus vulgaris (Krupa et al, 1993), O2 evolution in Anacystis nedulens and photosystem II (PS II) in isolated chloroplasts of maize and spinach (Bazzas et al, 1974).…”

The present study was designed with an objective to elucidate the effect of the exogenous application of 10 -5 M of salicylic acid (SA) to the foliage of the chickpea plants exposed to 0, 25, 50 or 100 mg cadmium (Cd) per kg of soil. The foliage of the plants grown in soil amended with varying doses of Cd was sprayed with 10 -5 M of SA at 30 days after sowing (DAS). The plant samples were collected at 60 and 90 DAS to assess various parameters. The damage caused due to the Cd exposure was partially overcome by the exogenous application of SA. The SA treatment resulted in a significant increase of growth, photosynthesis, yield and the activity of antioxidative enzymes viz. catalase, peroxidase and superoxide dismutase in the plants exposed to 0, 25 or 50 mg Cd per kg of soil. However, the treatment did not prove to be fruitful in alleviating completely the stress generated by 100 mg Cd per kg of soil.

“…High concentrations of Cd decreased the cell growth as well as the plant yield (Irfan et al, 2013). In this research, dry weight of cadmium treated plants decreased, too, but statistically significant only for P. vulgaris (Fig.…”

“…In A. thaliana Cd altered the activity of photosynthetic apparatus (Mohamed et al, 2012) while decreasing the potential quantum yield of PSII (Maksymiec et al, 2007). Similarly, the synthesis and level of pigments are decreased in other plant species under the influence of Cd (Mohamed et al, 2012;Irfan et al, 2013).…”

One of the most toxic metals is cadmium, which inputs include those from commercial fertilizers, sewage sludge and other wastes used as soil amendments and also atmospheric deposition. The aim of this experiment was to study the dynamics of photosynthetic parameters of bean (Phaseolus vul garis L.) and broad bean (Vicia fabo L.) under strong cadmium stress effect. Plants were sown in a neutral (pH 6.0-6.5) peat substrate, when 2nd true leaf unfolded, growth substrate was watered with 6 mM concentration CdSO 4 solution. Gas exchange parameters (photosynthetic rate (Pn), transpiration rate (Tn), intercellular CO 2 concentration (Ci) and water use efficiency (WUE)) were measured every day with portable photosynthesis system LI-6400. Content of photosynthetic pigments was analyzed in acetone extract using a spectrophotometer on the last 5th day of the experiment. On the first day of treatment the Pn of Cd treated P. vulgaris plants decreased only by 4.3% and statistically insignificant, while Pn of V. fabo decreased by 35.9% (p < 0.05). Pn of P. vulgaris was decreasing till 3rd day after treatment, when it was 96% (p < 0.05) lower compared to reference treatment. On the contrary, the lowest Pn of Cd treated V. fabo plants was on the first day and it started to increase from the second day till the last one. WUE of Cd treated P. vulgaris was decreasing till the third day too and it improved a little on the last one, but still it was 54% (p < 0.05) lower compared to the re ference. While WUE of V. fabo increased by 23% (p < 0.05) and 16% (p > 0.05) on the first and the last day after Cd treatment, respectively compared to the reference. The changes, detected on the last day of the experiment, of chorophyll a and b ratio were different too, i. e. for P. vulgaris it decreased by 5.7% (p > 0.05), and for V. fabo -increased by 1.4% (p > 0.05) compared to the reference. Also decrease of dry biomass of P. vulgaris was greater than that of V. fabo.
