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.

TL;DR: It is postulate that ROS and oxidative PTM could be part of a general mechanism, specifically affecting G1/S transition and progression through S phase, which would rapidly block cell cycle progression and would allow the cellular defence system to be activated.

TL;DR: Results indicate that light is involved in Cd(2+)-induced CATA3 enhancement, which leads to the synthesis of CAT isoforms less sensible to oxidation, and that chloroplast might be the main source of ROS responsible for this process.

TL;DR: The level of the mRNA of CATA3 and CATA4 increased with the presence of the metal after 4h of exposure, which indicates that the mechanism of CAT inactivation by Cu(2+) involves oxidation of the protein structure.

TL;DR: The results indicated that PCs synthesis was an important mechanism for Cd detoxification in sunflower calluses, but the capacity to grow in the presence of Cd is related to the tissues ability to maintain high intracellular levels of GSH.
