TL;DR: This article reviews current knowledge of uptake, transport and accumulation of Cd in plants and gives an overview of C d-detoxification mechanisms, Cd-induced oxidative damage and antioxidant defenses in plants, and presents a picture of the role of reactive oxygen and nitrogen species in Cd toxicity.
Journal ArticleDOI
Polyamines and abiotic stress: recent advances.
TL;DR: Information is summarized about the involvement of polyamines as antioxidants against the potential abiotic stress-derived oxidative damage and other types of abiotic stresses, such as mineral deficiencies, chilling, wounding, heavy metals, UV, ozone and paraquat, where polyamine metabolism is also modified.
Journal ArticleDOI
Nitric oxide protects sunflower leaves against Cd-induced oxidative stress
TL;DR: The results suggest that the exogenous application of NO could be advantageous against Cd toxicity, and could confer tolerance to heavy metal stress in plants.
Journal ArticleDOI
Polyamines as protectors against cadmium or copper-induced oxidative damage in sunflower leaf discs
TL;DR: Pretreatment with exogenously added polyamines showed that Spm reverted the effect of Cd 2+ and Cu 2+ on lipid peroxidation almost to control values, but more research is necessary to elucidate the precise role they played as antioxidants.
Journal ArticleDOI
Nitric oxide, polyamines and Cd-induced phytotoxicity in wheat roots.
TL;DR: The results strongly suggest that Cd and spermine treatments induce NO formation in wheat roots which, in turn, is involved in root growth inhibition.
