  • Heavy metals like cd, pb, zn, sb, ag, ni, hg, cu, sn are inducers of phytochelatin their formation therefore represents a true adaptive response to an environmental stress they act similarly to the metallothionein proteins that detoxify metals in humans and other animals, but in contrast, phytochelatins do not represent direct gene products.
  • Heavy metal stress is one of the major problems affecting agricultural productivity of plants natural flora show relative differences in their heavy metal tolerance capacity some plants grow well in a soil enriched with toxic levels of heavy metals while others could not grow.
