Copper toxicity in Prunus cerasifera: growth and antioxidant enzymes responses of in vitro grown plants (2005, background): “These include exclusion, restricting heavy metal uptake, inclusion (i.e. sequestrating and compartmentalizing metal in organs and organelles), and/or phytochelatins binding [30] [31] [32].”
Antioxidant defense system in leaves of Indian mustard (Brassica juncea) and rape (Brassica napus) under cadmium stress (2009, background): “decline in GSH pool observed in leaves of Brassica juncea treated plants (Fig. 3), could be due to its involvement in PCs synthesis ( Cobbett 2000 ).”

Mechanisms of Plant Resistance to Metal and Metalloid Ions and Potential Biotechnological Applications (2005, methodology): “shows that arsenic is complexed with sulfur in Indian mustard, presumably as PCs (Pickering et al., 2000), while a range of crude chromatography experiments suggest that PCs are associated with copper, mercury, cadmium and arsenic (Raab et al., 2003).

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 (2012, background): “In a second type of situation, HMs are intracellularly chelated through the synthesis of amino acids, organic acids, GSH, or HM-binding ligands such as metallothioneins (MTs), phytochelatins (PCs), compartmentation within vacuoles, and upregulation of the antioxidant defense and glyoxalase systems t”
Photosynthetic organisms and excess of metals (2005, background): “These molecules have been found in all autotrophic plants analyzed so far (reviewed in Gekeler et al. 1989, Cobbett 2000).”
Localization and chemical forms of cadmium in plant samples by combining analytical electron microscopy and X-ray spectromicroscopy (2006, background): “consistent with the high affinity of thiols for Cd, and with the role of these cysteinecontaining compounds in Cd detoxification [36,37].”
Significance of Sulfur Compounds in the Protection of Plants Against Pests and Diseases (2005, background): “In some plants, heavy-metal detoxification is mediated by GSH derivatives called phytochelatins, which have the general structure (γ -glutamylcysteine) n Gly, and by cysteine-rich proteins called metallothioneins ( Cobbett, 2000 ).”
