Journal ArticleDOI
Cadmium toxicity in plants
TL;DR: The role of the cell wall, the plasma membrane and the mycorrhizas as the main barriers against cadmium entrance to the cell, as well as some aspects related to phytochelatin-based sequestration and compartmentalization processes are reviewed in this paper.
Journal ArticleDOI

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
Effect of heavy metal ion excess on sunflower leaves: evidence for involvement of oxidative stress
TL;DR: Results indicate that excess Fe(II), Cu( II) or Cd(II) ions produce oxidative damage in plant leaves.
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.
