Phytochelatins and heavy metal tolerance
TLDR
In this article, the authors investigated the heavy metal binding properties of phytochelatins in heavy metal tolerant (Silene vulgaris) and sensitive (tomato) cell cultures, in water cultures of these plants and in a medieval copper mining dump.About:

Toxic metal accumulation, responses to exposure and mechanisms of tolerance in plants
TL;DR: This review discusses the molecular mechanisms of toxic metal accumulation in plants and algae, the responses to metal exposure, as well as the understanding of metal tolerance and its evolution.

Molecular Mechanism of Heavy Metal Toxicity and Tolerance in Plants: Central Role of Glutathione in Detoxification of Reactive Oxygen Species and Methylglyoxal and in Heavy Metal Chelation
Mohammad Anwar Hossain,Mohammad Anwar Hossain,Pukclai Piyatida,Jaime A. Teixeira da Silva,Masayuki Fujita +4 more
TL;DR: The aim of this review is to integrate a recent understanding of physiological and biochemical mechanisms of HM-induced plant stress response and tolerance based on the findings of current plant molecular biology research.

Arsenic speciation and distribution in an arsenic hyperaccumulating plant.
TL;DR: The results of this study demonstrate the ability of Brake fern as an arsenic hyperaccumulator, which transfers arsenic rapidly from soil to aboveground biomass with only minimal arsenic concentration in the roots.

Antioxidant enzymes responses to cadmium in radish tissues.
TL;DR: The results suggest that in radish, the activity of antioxidant enzymes responds to Cd treatment via the activation of the ascorbate-glutathione cycle for the removal of hydrogen peroxide, or to ensure the availability of glutathione for the synthesis of Cd-binding proteins.

Biochemical changes in barley plants after excessive supply of copper and manganese
Klimentina Demirevska-Kepova,L. Simova-Stoilova,Zlatimira Stoyanova,Regina Hölzer,Urs Feller +4 more
TL;DR: Oblzor et al. as discussed by the authors found that heavy metal accumulation in barley leaves leads to different display of oxidative stress, and changes in individual chloroplast proteins, including Rubisco subunits, and showed that low-molecular antioxidants were most probably the consequence of depletion in low-protein antioxidants as a result of their involvement in detoxification processes and disbalance in antioxidative enzymes.

A revised medium for rapid growth and bio assays with tobacco tissue cultures
Toshio Murashige,Folke Skoog +1 more
TL;DR: In vivo redox biosensing resolves the spatiotemporal dynamics of compartmental responses to local ROS generation and provide a basis for understanding how compartment-specific redox dynamics may operate in retrograde signaling and stress 67 acclimation in plants.

Phytochelatins: The Principal Heavy-Metal Complexing Peptides of Higher Plants
TL;DR: These peptides appear upon induction of plant cells with heavy metals and represent the principal metal-binding activities in the cells and are proposed as phytochelatin for this new class of natural products.

Free histidine as a metal chelator in plants that accumulate nickel
Ute Krämer,Janet D. Cotter-Howells,Janet D. Cotter-Howells,John M. Charnock,Alan J. M. Baker,J. Andrew C. Smith +5 more
TL;DR: In this article, the authors show that exposing hyperaccumu-lator species of Alyssum to nickel elicits a large and proportional increase in the levels of free histidine, which is shown to be coordinated with nickel in vivo.

Cadmium-Sensitive, cad1 Mutants of Arabidopsis thaliana Are Phytochelatin Deficient
TL;DR: Results demonstrate conclusively the importance of PCs for cadmium tolerance in plants and demonstrate that each mutant was deficient in PC synthase activity.
