Effect of NaHS on lipid peroxidation and the loss of plasma membrane integrity in roots under Se(IV) stress.

<p>The roots were exposed to water, 0.06 mM of Se(IV), 0.06 mM of Se(IV) and 0.5 mM of NaHS, and 0.5 mM of NaHS for 48 h. Then the roots were stained with Schiff's reagent (A), and Evan blue (B) for imaging, respectively.
