Physiological and biochemical roles of nitric oxide against toxicity produced by glyphosate herbicide in Pisum sativum

Physiological and biochemical roles of nitric oxide against toxicity produced by glyphosate... The present study assessed the response of pea plants exposed to herbicide induced oxidative stress in the plants present in agriculture field. We analysed the effect of exogenous nitric oxide (NO) regulated chlorophyll and protein content, nitrate reductase enzyme activity and antioxidant enzyme activity in herbicidetreated green pea (Pisum sativum L.). Glyphosate (0.25 mM) treatment alone or in combination with 250 μM sodium nitroprusside (SNP, 250 μM with glyphosate) was given to pea and we observed the changes in biophysical and biochemical parameters. During oxidative stress ion leakage is the first step of cellular damage. Supplementation of SNP with glyphosate significantly reduced ion leakage and moderately reduced H2O2 and malondialdehyde (MDA) content. SNP also increased chlorophyll content and antioxidant enzymes viz. superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (POD) activity as compared to herbicide treatment alone. The present result suggests that NO protects pea plants from damage caused by glyphosate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

The present study assessed the response of pea plants exposed to herbicide induced oxidative stress in the plants present in agriculture field. We analysed the effect of exogenous nitric oxide (NO) regulated chlorophyll and protein content, nitrate reductase enzyme activity and antioxidant enzyme activity in herbicidetreated green pea (Pisum sativum L.). Glyphosate (0.25 mM) treatment alone or in combination with 250 μM sodium nitroprusside (SNP, 250 μM with glyphosate) was given to pea and we observed the changes in biophysical and biochemical parameters. During oxidative stress ion leakage is the first step of cellular damage. Supplementation of SNP with glyphosate significantly reduced ion leakage and moderately reduced H2O2 and malondialdehyde (MDA) content. SNP also increased chlorophyll content and antioxidant enzymes viz. superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (POD) activity as compared to herbicide treatment alone. The present result suggests that NO protects pea plants from damage caused by glyphosate.
