ABSTRACT:
The protective effects of nitric oxide (NO) against arsenic (As)-induced metabolic disturbances in Glycine max L have been investigated. Accumulated data clearly approves that As exposure (10 and 50 uM) resulted in a declined growth of Glycine max L. seedlings. Moreover, above treatments also triggered a series of alterations in Glycine max L. with increased production of reactive oxygen intermediates such as superoxide radical and hydrogen peroxide, and damage to cellular membranes by producing malondialdehyde (one of the lipid peroxidized cyto toxic products). Overall results revealed that exposure of As suppressed growth and biomass accumulation, with altered protein, sugar and DNA contents, hence led to oxidative injury. In addition, proline, a compatible solute, accumulates under As stress. The concentration of sodium nitroprusside (0.02 mM, NO donor) was found to be quite effective in counteracting the adverse effects of As exposure. NO has found to enhance growth traits, biomass accumulation and restored oxidative stress markers. Therefore, it can be concluded that As-induced abnormalities are partially or fully reversed by a simultaneous application of As and NO donor and has an ameliorating effect against As-induced oxidative stress in Głycine max L.
