“…Many studies have demonstrated toxic effects of Cd 2+ on growth of plants, in both terrestrial and aquatic ecosystems. These toxic effects are probably caused by accumulation and redistribution of Cd 2+ in some plant organs, and by changes in plant protective enzymes (Chien et al, 2001), resulting in direct plant organ injuries (Reed et al, 1999). Therefore growth of plants (estimated from the yields, fresh weights, or heights) is inhibited.…”

“…The results indicate that plant yields decrease due to a toxic effect of heavy metals on the ecosystem (Scherer et al, 1997;Wu et al, 1997a). Cd 2+ can accumulate and redistribute in some plant organs, resulting in plant injuries (Lagriffoul et al, 1998;Reed et al, 1999), changes in plant protective enzymes (Chen et al, 1998;Chien et al, 2001), or changes in photosynthetic sensitivity of plants at different growth stages (Skorzynska Polit and Baszynski, 1997). Compared to the control, Cd treatments increase lipid peroxidation and autoxidation rates of plant leaves and roots estimated from rate of MDA formation (Zhang et al, 2000), excess CdCl 2 reduces SOD activity (Chien et al, 2001), and there is a relationship between the POD activity and the Cd content (Lagriffoul et al, 1998), so that some authors use enzyme activities of plants to reflect soil pollution levels.…”

Field experiments show that addition of Zn and other heavy metals can cause interactions with soil Cd, leading to increases in plant absorption coefficients, which are even more serious in acid and neutral soils (Wu et al, 1997b).…”

“…MDA content is an index of the membrane integrity and lipid peroxidation. Cd-induced increase in MDA content were reported for many plant species, including bean (Chaoui et al 1997), pea (Lozano-Rodriguez et al 1997Metwally et al 2005), rice (Chien et al 2001), sunflower (Gallego et al 1996), mustard (Mobin and Khan 2007), and maize (Pál et al 2007;Krantev et al 2008). In the present study, however, the MDA was similar in different Cd treatments, indicating the plants not suffering a Cd-induced oxidative damage.…”

To assess the role of salicylic acid (SA) in alleviating cadmium (Cd) toxicity in hemp (Cannabis sativa L.) plants, the growth parameters, Cd accumulation, photosynthetic performance and activities of major antioxidant enzymes were investigated in hemp seedlings treated with 500 lM SA, under 0, 25, 50, and 100 mg Cd kg -1 sands (DW) conditions, respectively. Cd exposure resulted in a small reduction in biomass (12.0-26.9% for root, and 8.7-29.4% for shoot, respectively), indicating hemp plants have innate capacity to tolerant Cd stress. This was illustrated by little inhibition in photosynthetic performance, unchanged malondialdehyde content, and enhancement of superoxide dismutase (SOD) and peroxidases (POD) activities in hemp plants. Cd content in root is 25.0-29.5 times' higher than that in shoot, suggesting the plant can be classified as a Cd excluder. It is concluded that SA pretreatment counteracted the Cd-induced inhibition in plant growth. The beneficial effects of SA in alleviating Cd toxicity can be attributed to the SA-induced reduction of Cd uptake, improvement of photosynthetic capacity, and enhancement of SOD and POD activities.

Xyloglucan is an important component of hemicellulose, and xyloglucan oligosaccharides (Xh), which are metabolized by xyloglucan, play an important role in plant growth and development. However, the regulatory effects of the external application of Xh under cadmium (Cd) stress have not been determined. In this study, we evaluated the mechanism by which Xh contributes to resistance to Cd stress in ramie, a candidate plant species for toxic ion removal. The external application of Xh effectively attenuated the effects of Cd on ramie growth and photosynthetic pigments. Cd stress can also inhibit the activity of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX), resulting in a significant increase in the extent of membrane lipid peroxidation. After the external application of Xh, antioxidant enzyme activity was up-regulated, and damage to membranes in plants was reduced. In addition, the external application of Xh increased Cd retention in roots, thereby significantly decreasing Cd content in shoots. The external application of Xh also regulated the subcellular distribution of Cd and increased the Cd content of the cell wall. In particular, a root cell wall analysis revealed that Cd+Xh treatment significantly increased the hemicellulose content in the cell wall and the amount of Cd retained. In summary, the external application of Xh alleviates Cd toxicity in ramie by increasing the hemicellulose content and the Cd fixation ability of the cell wall and by reducing membrane lipid peroxidation via antioxidant enzymes.
