Molecular and biochemical characterization of oxidative stress in tomato plants cultivated with lead (Pb)

Abstract

Heavy metals are dangerous pollutants of water and soil coming, in first place, from anthropogenic activity. Lead (Pb) can be accumulated in soil surface and it is easily take by plants inducing many symptoms of toxicity. Several research suggests that Pb toxicity leads to the induction of key enzymes of antioxidant defense system in tomato plants. This mini review will show the influence of Pb in some enzymes of tomato oxidative system focusing in the analysis of protein content and the enzymes glutathione reductase and superoxide dismutase in different parts of the plant (leaves and stem), some genes related to the oxidative stress of tomato were also study.

Effects of Ginger on Growth Indices and Pb Bioaccumulation of Tomato Fruits Cultivated in Lead and Spent Engine Oil-Contaminated Soils

“…Toxic effects of lead in soil include overproduction of reactive oxygen species (ROS) by plants, inhibition of ATP production, lipid peroxidation, and DNA damage (Molina and Segura, 2021). Lead in excess amounts also decreases seed germination, root elongation, seedling development, plant growth, transpiration, chlorophyll production, and water and protein content, among other things (Ardisana et al, 2018;Ilahy et al, 2021). Acute toxicity is related to occupational exposure and is quite uncommon (Rebelo and Caldas, 2016).…”
