Abstract: | Copper nutrition inhibited lipid peroxidation in root nodules of yellow lupin plants at the early growth stages by about 50
%. The antioxidative activity of copper in the process of lipid peroxidation could be associated with Cu taking part in oxidative
reaction of nodule catechol-like siderophores and its effect on iron accumulation and reactivity. The obtained results, for
the first time, suggest that the ability of copper to inhibit lipid peroxidation in nodules could be considered as a major
function for Cu requirements by symbiotic N2 fixation in grain legume nodules. |
