Antioxidant system in implementing protective action of nitric oxide in wheat plants under water deficit

Year: 2020

Pages: 318-323

Number: Volume 12, issue 3

Type: scientific article

Summary:

We studied the effect of a nitric oxide donor - SNP (sodium nitroprusside,) - on the growth and state of the components of the antioxidant system of wheat seedlings under conditions of dehydration modeled by 12% PEG. The protective effect of 200 µM SNP pretreatment on wheat plants was revealed, as evidenced by an increased content of reduced glutathione (GSH), a decrease in stress-induced accumulation of MDA, and glutathione S-transferase (GST) activity, which is reflected in maintaining a high level of growth processes. For the first time, the role of wheat germ agglutinin protein (WGA) in the manifestation of the protective effect of nitric oxide on wheat plants under stressful conditions is shown

Keywords:
