Effect of arginine pre-treatment on nickel accumulation and alleviation of the oxidative stress in Hyoscyamus niger

Nickel is essential for many plant species to complete their life cycle but higher concentrations of this metal are toxic and may severely interfere with many physiological and biochemical processes of plants. In recent researches, either sodium nitroprusside (as nitric oxide donor) or exogenous pol...

In recent researches, either sodium nitroprusside (as nitric oxide donor) or exogenous polyamines were used to counteract the effect of heavy metal stress. In this research hyoscyamus plants were pre-treated with 10 and 20 µM Arg (as a precursor of NO or polyamines) and then plants were treated with 50 and 100 µM Ni. Elevated hydrogen peroxide content and lipoxygenase (LOX) activity showed that Ni induced oxidative damages. Antioxidant enzyme activity also increased in those plants which were under Ni stress. In plants, which were pretreated with Arg, the concentration of Ni increased in shoot, while the H2O2 content and the activity of LOX, catalase (CAT), guiacol peroxidase (GPX) and ascorbate peroxidase (APX) enzymes decreased.
