Figure 6. The MzASMT9-GFP conferred transgenic Arabidopsis enhanced salt tolerance via efficient ROS mitigation.

(a) The phenotype of wild type and three transgenic Arabidopsis lines growing on MS media (first line) and MS media supplemented with 100 mM NaCl (second line). (b) and (c) The fresh weight and root length in wild type and transgenic plants on MS media and MS media supplemented with 100 mM NaCl. (d) and (e) The ROS level in the chloroplasts of wild type and transgenic plants on MS media and MS media supplemented with 100 mM NaCl. Under the confocal microscope (40 × 10), the green fluorescence shows the ROS level dyed by CM-H₂DCFDA (488 nm) and the red fluorescence marks the chloroplast (543 nm). Asterisks (*) and different letters indicate significant differences from the control (*P < 0.05).
