Relative salt tolerance of wild type (WT) and transgenic plants with <i>OsAPx2</i> overexpression in <i>Medicago sativa</i> (T#1 and T#5) under salt stress.

<p>A: WT and transgenic seeds germinated in 1/2 ·MS solid medium agar plates for 1 week. B, C, D: WT and transgenic seeds germinated in 1/2 MS with 125, 150, and 175 mM NaCl. E: Effects of salt on the root lengths of the WT and transgenic plants overexpressing the <i>OsAPx2</i> gene. The figure shows the root lengths of the WT and two transgenic lines (T#1 and T#5) after 1 week of salt treatment. This shows that the root lengths of the transgenic plants are longer than those of the WT plants. Data on the profile E note mean ±SD (n = 20). F: Analysis of the content of H₂O₂ via DAB shows that the WT has higher content than the transgenic type.
