Sulphur deficient plants may switch to non-sulphur-based tolerance mechanisms, which often involve proline . However, phytochelatins appear to be essential for metal tolerance.

Webb1.8 Phytochelatins (PC) Phytochelatins bind various metals (e.g., As, Cd, Zn or Cu over carboxyl and sulfhydryl residues), then biosynthesis is controlled by metal Cd or metalloid As. Overexpression of phytochelatins synthase genes enhances Cd tolerance in bacteria and yeast (Gupta et al., 2013). 1.9 Reduced glutathione (GSH) Webb44.

WebbAbstract Among the heavy metal-binding ligands in plant cells the phytochelatins (PCs) and metallothioneins (MTs) are the best characterized. PCs and MTs are different classes of cysteine-rich, heavy metal-binding protein molecules. PCs are enzymatically synthesized peptides, whereas MTs are gene-encoded polypeptides. Recently, genes encoding the … WebbBackground: Multivariate analysis is a chemometric tool that has been little explored to determine physiological status under heavy metal stress. Nevertheless, PCA has an unexplored potential to determine the plant physiologic status and its modification under stress factors like heavy metals. Objectives: This work aims to assess the physiological …

Webband phytochelatins was measured by High Performance Liquid Chromatographic (HPLC) technique. In both the cases, it was observed that 800 M of zinc treatment is the highest dose that the plants can withstand. A sharp decrease in the expres-sion of the genes was observed under high level of metal toxicity.
