Název v původním jazyce

Nitric oxide donor modulates cadmium-induced physiological and metabolic changes in the green alga Coccomyxa subellipsoidea

Popis výsledku v původním jazyce

The impact of two concentrations (10 and 100 mu M) of cadmium(Cd) and nitric oxide (NO) donor (sodium nitro-prusside, SNP) alone or together on green alga Coccomyxa subellipsoidea was studied. Stimulatory impact of Cd and SNP on NO formation was synergistic in combined treatments and correlated with the increase of ascorbic acid. Exogenously applied Cd concentration (and not SNP co-application) was the main determinant of Cd uptake, phytochelatin 2, and reduced (GSH) and oxidized (GSSG) glutathione amounts. Glutathione reductase activity was depleted while ascorbate peroxidase activity enhanced by high SNP under both Cd concentrations. This may be related to the appearance of oxidative stress detected by fluorescence microscopy of oxygen radicals and lipid peroxidation in high SNP and/or Cd treatments.
