“…Under stressful conditions the protective system can be over ridden by a rapid production of large amounts of ROS, leading to various structural modifications in proteins (Cargnelutti et al, 2006). These oxidative modifications are characterized by the formation of carbonyl derivatives on side chains of histidine, arginine, lysine, and proline residues (Shacter et al, 1994).…”

“…These results indicated that the increment of air Hg level enhanced Hg accumulation and further induced free proline generation as well as membrane lipid peroxidation in Columns at the same time with different letters denote significant differences at p<0.05 among the treatments of soil Hg exposure maize leaves. A number of studies have reported the quantitative increases in proline and MDA under heavy metal stress (Cargnelitti et al 2006;Cho and Park 2000;Moreno-Jiménez et al 2006;Radic et al 2010;Zhang et al 2008). Cho and Park (2000) reported that a consistent increase in the MDA level paralleled an increase in the Hg concentration in tomato leaves.…”

“…Mercury (Hg) is a strong phytotoxic metal, which has wideranging adverse effects on the physiological activities of plants, such as prevention of mineral nutrient uptake (Patra and Sharma 2000); inhibition of photosynthesis (Krupa and Baszynski 1995;Lu et al 2000;Pisani et al 2011), transpiration, and water uptake (Zhang and Tyerman 1999); and induction of lipid peroxidation (Cho and Park 2000;Cargnelitti et al 2006;Moreno-Jiménez et al 2006). Mercuric ions react specifically with sulfhydryl groups in proteins and induce the Fenton reaction, resulting in oxidative stress and membrane lipid peroxidation in plants (Han et al 2007).…”

“…Heavy metal stress in all living organisms often results in the production of reactive oxygen species (ROS), which are relatively reactive compared to molecular oxygen and thus potentially toxic (Cargnelutti et al 2006;Van Assche and Clijsters 1990). A regulated balance between oxygen radical production and destruction is achieved by the plant antioxidative system that includes enzymatic molecules such as superoxide dismutase (SOD; enzyme classification [EC] number 1.15.1.1), ascorbate peroxidase (APX; EC 1.11.1.11), nonspecific peroxidases (POX; EC 1.11.1.7), and catalases (CAT; EC 1.11.1.6) and various antioxidants of low molecular mass (e.g., α-tocopherol and β-carotene) (Van Assche and Clijsters 1990; Dixit et al 2001).…”
