Abstract: Salt stress is one of the major abiotic stress that limits crop growth, development and production, it is a growing problem for agricultural-wordwide. Seed germination is a critical stage in the development of crops that grow in saline soils. An improved understanding of molecular mechanism to NaCl treatment on seed germination may has important significance for development of crops with increased tolerance to NaCl stress. In this study, we carried out the studies of A.thaliana glutamine synthetase ( AtGS1.5 ) responses to salt stress during seed germination. The results show that the AtGS1.5 overexpression transgenic Arabidopsis plants enhance the tolerance to salt stress comparable to that of wild type (WT) and Arabidopsis AtGS1.5 mutants ( atgs1.5 ) plants. Furthermore, overexpression of AtGS1.5 gene increased the activity of glutamine synthase and decreased NH 4 + content in transgenic plants.
