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.

TL;DR: Nitrate-fed and dark-stressed bean and pea plants were used to study nodule senescence and thiol tripeptides of untreated nodules, indicating sugar deprivation as the primary cause of activity loss.
Antioxidant Defenses against Activated Oxygen in Pea Nodules Subjected to Water Stress.
TL;DR: The involvement of activated oxygen in the drought-induced damage of pea nodules was examined and the decline in the antioxidant capacity of nodules may result from a restricted supply of NAD(P)H in vivo for the ascorbate-glutathione pathway and from the Fe-catalyzed Fenton reactions of asCorbate and glutathione with activated oxygen.

TL;DR: Common beans (Phaseolus vulgaris L.) were exposed to continuous darkness to induce nodule senescence, and several nodule parameters were investigated to identify factors that may be involved in the initial loss of N2 fixation.

Involvement of Activated Oxygen in Nitrate-Induced Senescence of Pea Root Nodules.
TL;DR: Comparison of nitrate- and drought-induced senescence shows an important difference: there is no lipid degradation or lipid peroxide accumulation with nitrate, indicating that lipid peroxidation is not necessarily involved in nodule senescENCE.
