Abstract In this study, molecular biology methods were use to analyze germinating overexpression transgenic plants and mutants of Arabidopsis thaliana glutamine synthetase genes GLN1;1 and GLN1;5 in response to salt stress, and activity change of Arabidopsis glutamine synthetase. The results showed AtGLN1;1 and AtGLN1;5 performed different expression profiles in different tissues, growth stages and under salt stress. The overexpression of AtGLN1;5 gene could contribute to strengthen germination and growth progress of Arabidopsis under saline environment
