Hydrophytes lack potential to exhibit cadmium stress induced enhancement in lipid peroxidation and accumulation of proline

Metal accumulation and physiological responses induced by copper and cadmium in Lemna gibba, L. minor and Spirodela polyrhiza

“…Additionally, Piotrowska et al (2010) reported that inhibition of CAT activity was probably caused by the toxic effect of H 2 O 2 and other ROS. Similar to results of this study, reduced activity of CAT was reported in plants under Cd (Bacoppa monnieri, W. arrhiza and G. densa), Cu (L. minor, S. polyrhiza), Pb (W. arrhiza) and Cr (cauliflower) stresses (Dhir et al, 2004;Shanker et al, 2005;Kanoun-Boulé et al, 2009;Yilmaz and Parlak, 2011).…”

“…Increases in the level of MDA have been reported in aquatic plants such as G. densa (Cd), S. polyrhiza (Cd), Wolfia arrhiza (Cu, Pb), Potomogeton pusillus (Cu) and N. officinale (Pb) (Magdelena et al, 2009, Keser andSaygideger, 2010;Piotrowska et al, 2010;Yilmaz and Parlak, 2011). However, similar to results of this study, reduced MDA contents were reported in Cd-exposed Ceratophyllum, Hydrilla and Wolffia and Hg-exposed Bacopa monnieri plants (Dhir et al, 2004;Singh et al, 2006). Decreased MDA content can be considered as an indication of low peroxidation of lipids which can be caused by increased activity of antioxidant (Zhang et al, 2007).…”

Cadmium Toxicity Affects Phytochemicals and Nutrient Elements Composition of Lettuce (Lactuca sativa L.)

“…Although higher Cd levels resulted in no significant effect on proline content, there was 27% increase in proline at 9 mg/L Cd compared to control. Similar accumulation of proline in the shoots of Brassica juncea, Triticum aestivum, and Vigna radiate was demonstrated by Dhir et al [50] in response to Cd toxicity but decreased with the exposure to Cd in hydrophytes (Ceratophyllum, Wolffia, and Hydrilla).…”

Effect of cadmium and lead on growth, biochemical parameters and uptake in Lemna polyrrhizaL.

“…Proline accumulation in shoots of Brassica juncea, Triticum aestivum and Vigna radiata in response to cadmium toxicity was demonstrated by Dhir et al (2004) but they found that proline accumulation decreased with the exposure to cadmium in hydrophytes (Ceratophyllum, Wolffia, and Hydrilla). It has been often suggested that proline accumulation may contribute to osmotic adjustment at the cellular level (Perez-Alfocea e t al.…”
