Effect of drought and osmotic stress on plant performance. For each experiment, twelve plants of wild type (WT) and each transgenic line (S13, S15) were used. (a) Wild type and transgenic plants grown in soil were watered with 60 g/l PEG-6000. Photograph was taken after 21 days of treatment. (b) Water was withheld for 21 days to impose drought stress. (c) Drought stressed plants were re-watered and grown for seed setting. (d) Proline content of wild type and transgenic plants after treatment with 100 or 200 mM NaCl for 24 h. Results are presented as means and standard errors from three independent experiments. ** indicates significant differences in comparison to the wild type at P < 0.01 (Student’s t-test)
