Abstract

Proline and increasing Salt tolerance in transgenic tobacco (Nicotiana tabacum) containing P5CS gen under in vitro salt stress condition with a completely randomized design with three replications. Tobacco plants transferred to MS medium containing 100 and 200 mM NaCl, then foliar application of two Glycine betaine concentrations, including 20 and 40 mg L-1 were applied on the surface of the plants with four to six leaves. After 4 weeks post treatment results showed that, exogenous Glycine betaine under salt stress increased fresh and dry weight, content of K+, leaf area, endogenous Glycine betaine and soluble sugar. In contrast, the amount of photosynthetic pigments, Proline, content, Na+ content, and Na+/K+ ratio were decreased. The results of this study showed that, exogenous application of Glycine betaine in Tobacco plants was effective in reducing the negative effects of salt stress and improved growth parameters. It also looks like, communion cooperation of these osmolytes to cope with stress conditions has possibly been occurred. According to the results of this study, that cooperative roles of Glycine betaine and Proline in membrane stability and reducing the negative effects of salinity in both transgenic and non-transgenic plants it can be suggested.
