Phytochelatin and its function in heavy metal tolerance of higer plants;

Recently,phytochelatin synthase(PCS) genes in higher plants and fission yeast have been isolated and characterized,and that some genes similar to the plant phytochelat.

Cd) by the cysteine-richpolypeptides known as phytochelatins (PC) arethought to confer heavy metal hyperaccumulationand tolerance in some plant species.

The role of metallothioneins and phytochelatins in heavy metal tolerance of plants;

Phytochelatins, a series of non-protein thiol compounds, are found universally in higher plants.

Recently,phytochelatin synthase(PCS) genes in higher plants and fission yeast have been isolated and characterized,and that some genes similar to the plant phytochelat.
