ABSTRACT
Deprivation of accepted resources is perhaps one of the lethal lapses mankind has ever prepared in its voyage of progress and civilization. All the natural resources are contaminated with lethal lapses. Among them the land and water resources are worst affected and under continuous stress both biotic and abiotic, due to anthropogenic interventions. If we talk about the soul of infinite life i.e. SOIL then it seems to appear the primary recipient by design or accident of a myriad of waste products and chemicals used in modern society. Soil contamination can be defined as the addition of any substance to soil that may exert adverse effects on its functioning and capacity to yield a crop. Contamination of heavy metal is of special worry due to well-known reports emanating both from India and abroad. Various diseases and disorders are observed both in human and livestock due to metal toxicity; the greatest problems most likely involve mercury, cadmium, lead, chromium, arsenic, nickel, etc. To a greater or lower degree all of these elements are toxic to humans and animals. Cadmium is extremely toxic, causing heart and kidney disease, bone embrittleness; Cr, Ni, and Pb are moderately so, which are responsible for mutagenic, lung cancer, convulsion and brain damage like some deadlier diseases. Polyamines have the ability to combat various abiotic stresses. In this review we have attempted to depict the roles of polyamines in ameliorating cadmium induced stress responses in sorghum plants.
