Drought induces oxidative stress in pea plants
Jose F. Moran,Manuel Becana,Inaki Iturbe-Ormaetxe,Silvia Frechilla,Robert V. Klucas,Pedro M. Aparicio-Tejo +5 more
TL;DR: In this article, it was shown that increased levels and decompartmentation of catalytic metals occurring during water stress are responsible for the oxidative damage observed in vivo in leaves, i.e., increased levels of ascorbate, H2O2, and catalytic metal ions in leaves.
Journal ArticleDOI
Oxidative Damage in Pea Plants Exposed to Water Deficit or Paraquat
TL;DR: In this paper, the application of a moderate water deficit (water potential of −1.3 MPa) to pea (Pisum sativum L. cv Lincoln) leaves led to a 75% inhibition of photosynthesis and to increases in zeaxanthin, malondialdehyde, oxidized proteins, and mitochondrial, cytosolic, and chloroplastic superoxide dismutase activities.
Journal ArticleDOI
Complexes of iron with phenolic compounds from soybean nodules and other legume tissues: prooxidant and antioxidant properties
TL;DR: It is reasoned that under the microaerobic and acidic conditions prevailing in nodules, phenolics are likely to act primarily as antioxidants, decreasing oxidative damage to biomolecules.
Journal ArticleDOI
Iron-dependent oxygen free radical generation in plants subjected to environmental stress: toxicity and antioxidant protection
TL;DR: Oxidative stress may lead to metabolic dysfunction and ultimately to plant cell death, so it needs to be estimated conveniently by quantifying the oxidation products of lipids, proteins, and DNA and DNA damage may also prove to be a useful marker for stress studies in plants.
Journal ArticleDOI
Some Enzymes of Hydrogen Peroxide Metabolism in Leaves and Root Nodules of Medicago sativa
TL;DR: The significantly lower contents of H( 2)O(2) and malondialdehyde in nodules with respect to those in leaves reveal that the above-mentioned bacteroid and cytosol enzymes act in an efficient and combined manner to preserve integrity of nodule cell membranes and to keep leghemoglobin active.
