TL;DR: The current review gives an overview on Cd-induced ROS production and anti-oxidative defense in organisms under different Cd regimes and the C d-induced oxidative challenge is discussed with a focus on damage and signaling as downstream responses.

TL;DR: This review aims at extending the current concept of antioxidants functioning during abiotic stress, with special focus on the emanate role of sugars as true ROS scavengers, as different organelles seem to exploit distinct mechanisms.

TL;DR: The metal-induced cellular redox imbalance is strongly dependent on the chemical properties of the metal and the plant organ considered, and the stress intensity determines its involvement in downstream responses in relation to oxidative damage or signalling.

TL;DR: This review highlights the current understanding on metal uptake, translocation and detoxification in planta, and their impact on plant growth and health, and special attention is paid to the central role of glutathione (GSH) in this process.

TL;DR: A model for lignification as defense response is proposed, with a central role for hydrogen peroxide as substrate and signaling molecule, and the importance of AsA in the apoplast is highlighted.
