Toward Understanding the Influence of Soil Metals and Sulfate Content on Plant Thiols

The relationship that exists between short- and long-chain PCs and glutathione levels in plants and changes in the soil metals content was investigated. The contaminated site had elevated cadmium, copper, lead and sulfate levels. This increase of metal and sulfate levels in the soil at the contamina...

Summary:The relationship that exists between short- and long-chain PCs and glutathione levels in plants and changes in the soil metals content was investigated. The contaminated site had elevated cadmium, copper, lead and sulfate levels. This increase of metal and sulfate levels in the soil at the contaminated site correlated with a rise in plant total glutathione (GSH sub(T)) and cysteine (CYS sub(T)). These increases were not attributed an elevation in total phytochelatin levels. A significant increase in the ratio of short chain phytochelatins to the total phytocelatin stores was observed. The individual effects of metals and sulfate on glutathione, short-chain PCs and long-chain PCs and long-chain PCs levels were dissimilar.
