Nitric Oxide Alleviates Oxidative Stress Caused by Lanthanum in Rice Leaves

Journal Article (Journal Article)

The effect of NO on lanthanum-induced antioxidant activities in rice was evaluated. The results showed that the uptake and translocation of La from root to shoot were obviously inhibited by 10 μmol · L sodium nitroprusside (SNP), a donor of NO, in the seedlings grown in Mura B nutrient solution with 100 μmol · L La. Although the content of ascorbate acid (AsA) were scarcely affected by La or NO in our experiment, La decreased significantly the activity of SOD and content of GSH, while promoted H O content in leaves. Furthermore, NO blocked these La effects. Taken together, the results suggested that NO relieved La toxicity in rice. A possible role for NO effects on antioxidant activity was discussed. © 2007 The Chinese Society of Rare Earths. -1 -1 2 2
