Heavy metals are
important environmental pollutants and their toxicity is a problem of
increasing significance for ecological, evolutionary and environmental
reasons. The interference of germination related proteins by heavy
metals has not been well documented at the proteomic and genomic level.
In the current study, molecular responses of germinating groundnut
seeds were investigated under Zinc stress. The SDS-PAGE showed the
preliminary changes in the polypeptides patterns under Zinc stress.
Restriction digestion banding pattern of EcoRI and Hind III enzymes
showed distinct banding pattern in the treated plants.
Key
words: Heavy metal stress, Arachis hypogea L., SDS-
PAGE - polypeptides, Restriction enzymes
