The <i>SoBADH</i> transgenic plants showed improved ROS scavenging and proline contents under 200 mM salt stress.

<p>A, detection of salt stress-induced H₂O₂ production by DAB staining in the leaves of the transgenic and WT plants; B–C, H₂O₂ and MDA contents in the leaves of the transgenic and WT plants; D, changes of SOD activity in transgenic and WT plants after NaCl treatment. E, proline contents in the leaves of the transgenic and WT plants. OE1–OE3, <i>SoBADH</i> overexpressing transgenic lines; WT, wild-type plant. Values represent the mean ± SD (n = 9). Asterisks indicate a significant difference from that of WT at * P<0.05 or ** P<0.01 by <i>t</i>-test.
