Quantitative analysis of Sucrose Synthase1 Gene expression in wheat under salinity stress

Aim: In this study, the effect of salinity stress on quantitative gene expression of sucrose synthase1, relative water content and the uptake ratio of sodium to potassium in the leaves of wheat were evaluated.
Material and Wheat seedlings treated with 100 and 200 mM sodium chloride and at times zero, 6, 12, 24 and 36 hours after treatment relative water content, the uptake ratio of sodium to potassium in the leaves and quantitative gene expression of Sus1 by qRT-PCR method were studied.
Results showed a significant decrease in relative water content, increase in the uptake ratio of sodium to potassium by leaves and increase in the relative expression of sucrose synthase1 gene at treated plants compared to control group.
Generally, increase in the expression of sucrose synthase 1 gene could be one of the possible mechanisms in the process of tolerance to salinity stress.
