Figure 6. Performance of PfHSP17.2-overexpressing transgenic plants under salt stress. (a) Germination on different salt MS (0 mm NaCl, 150 mm NaCl, 200 mm NaCl); (b) germination rate; (c) root number; (d) root length; (e) phenotypic comparison of the plants under salt stress; (f) proline content in WT and transgenic plants in response to salt stress. Error bars indicate SD (n=3). *p<0.05, ** p<0.01. WT, wild type; L223, L253, two transgenic Arabidopsis lines.
