“…Radical (i.e. superoxide radical anion and hydroxyl radicals) scavenging properties of polyamines in solution were also documented (Drolet et al, 1986); however, in contrast with the studies of the group of Tadolini, who observed marked effects at submicromolar concentrations of spermine, these results were obtained only at much higher polyamine concentrations. Related to this aspect, it is known that amines can yield derivatives of phospholipid hydroperoxides in the presence of haem (lio & Yoden, 1988).…”

“…The transformation of 1-aminocyclopropane-I-carboxylate into ethylene can also be induced by radicals (e.g. superoxide radical anion) generated from plant membranes (Yang & Hoffman, 1984), and polyamines acting as scavengers (see above) were found to strongly interfere with such a reaction (Drolet, et al, 1986). The specificity and the physiological meaning of these observations are difficult to assess at present, since we do not know whether senescence induced by ethylene can be regulated by signals which affect, in vivo, polyamine biosynthesis in plants.…”

“…The protection afforded by PAs against PQ toxicity has been proposed to involve scavenging of PQ-derived free radicals (Minton et al 1990). This proposal was based mainly on the previously reported free radical scavenging properties of PAs (Drolet et al 1986). Chang and Kao (1997) proposed the protective effect of PAs in PQ stressed rice leaves.…”

Polyamines (PAs) are aliphatic polycations that are widespread in living organisms. In this review, we are focusing the correlation between endogenous PA titers and physiological perturbations and on the protective role of various analogues of PAs against abiotic stresses. PAs are involved in many physiological processes, such as cell growth and development and also respond to diverse abiotic stresses. Polyamines level shifts in different ways depending on several factors, such as plant species, tolerance or sensitivity to stress, and duration of stress. Exogenously supplied PAs protected plants from abiotic stress, whereas transgenic plants overexpressing PA biosynthetic genes exhibited stress tolerance. On the other hand, loss-of-function mutant of PA biosynthetic genes, or decrease of PA titers, resulted to decrease stress tolerance.

“…Polyamines have also been suggested to function as free radical scavengers (Drolet et al, 1986;Ye et al, 1997). Their ability to decrease lipid peroxidation, under stress conditions has been attributed to their supposed ability to stabilize membranes by association with negatively charged phospholipids (Besford et al, 1973).…”

Chickpea plants were subjected to salt stress for 48 h with 100 mM NaCl, after 50 days of growth. Other batches of plants were simultaneously treated with 0.2 mM sodium nitroprusside (NO donor) or 0.5 mM putrescine (polyamine) to examine their antioxidant effects. Sodium chloride stress adversely affected the relative water content (RWC), electrolyte leakage and lipid peroxidation in leaves. Sodium nitroprusside and putrescine could completely ameliorate the toxic effects of salt stress on electrolyte leakage and lipid peroxidation and partially on RWC. No significant decline in chlorophyll content under salt stress as well as with other treatments was observed. Sodium chloride stress activated the antioxidant defense system by increasing the activities of peroxidase (POX), catalase (CAT) superoxide dismutase (SOD) and ascorbate peroxidase (APX). However no significant effect was observed on glutathione reductase (GR) and dehydro ascorbate reductase (DHAR) activities. Both putrescine and NO had a positive effect on antioxidant enzymes under salt stress. Putrescine was more effective in scavenging superoxide radical as it increased the SOD activity under salt stress whereas nitric oxide was effective in hydrolyzing H 2 O 2 by increasing the activities of CAT, POX and APX under salt stress.
