Abstract
Aluminum (Al) toxicity promotes oxidative damage in plants, while nitric oxide (NO) may exert a beneficial effect on Al toxicity condition in soybean. Pretreatment with NO donor sodium nitroprusside (SNP) before soybean exposure to Al significantly reduced Al accumulation and MDA induction in the root apex. Pretreatment with SNP also increased the relative root elongation, chlorophyll content, and activity of the protective enzyme peroxidase compared to Al treatment alone. These results show the effect of exogenously applied NO as a protector against oxidative stress induced by Al. Moreover, the ameliorating effect can be reversed by the addition of NO scavenger 2-(4-carboxy-2-phenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO) in the presence of Al.
