Abstract
This paper investigates heavy metal uptake, growth and protein expression of two tobacco cultivars (Flue cured Virginia, Dark sun cured) when exposed to heavy metals (Cd, Cr and Pb) and EDTA. Statistically analysis of the data revealed that growth parameters and heavy metal accumulation were significantly (p<0.05) affected by heavy metal and EDTA application. Minimum leaf fresh weight, dry weight and shoot length was measured by the application of Cr (500 mg kg-1) as compared to other heavy metals and controls. Maximum reduction in leaf fresh weight, dry weight and shoot length was noted with the exposure of tobacco plants to 5 mM EDTA compared with control (0 mM EDTA). Heavy metals uptake was more by Flue cured Virginia than Dark sun cured. Tobacco cultivars exposed to heavy metal and EDTA resulted in the expression of several proteins of different molecular weight.
