• oxidative stress
  • Despite a significant increase in the H2O2 content in both As20 and As30 plants, the former, unlike As30 plants, did not experience any type of As-induced oxidative stress (membrane lipid peroxidation, electrolyte leakage). (deepdyve.com)
  • By contrast, soil amendment with phosphorus (200 mg P/kg) at As30 prevented As-induced oxidative stress through the reduction of the H2O2 level even below As0. (deepdyve.com)
  • plant
  • Normal to high levels of leaf APX, CAT, and redox pool of ascorbate effectively balanced the elevated SOD activity at As20, maintaining the H2O2 concentration higher than control but obviously in favor of As20 plant growth. (deepdyve.com)
  • rapidly
  • In the absence of a reductase, two monodehydroascorbate radicals disproportionate rapidly to dehydroascorbic acid and ascorbate. (wikipedia.org)
  • However, monodehydroascorbate is a radical and if not rapidly reduced it disproportionates into ascorbate and dehydroascorbate. (wikipedia.org)
