GENOTOXIC OF SOME PESTICIDES ON SOME HIGHER PLANTS

Purified extract of phycocyanin (purity 1.8) from Spirulina platensis was tested for genotoxic and inhibitory effect against mutagenicity produced by curzate fungicide on Vicia faba and Allium cepa. Selected concentration of 0.2% of aqueous solution of phResults of cytological studies indicated that two experimental agents are similar in their mode of action on mitosis, meiosis and produce similar types of aberrations, where stickiness was found to be the most obvious kind. However, mixing curzate with 0.Results of molecular studies on M1 progeny were carried out by using SDS-PAGE and RAPD tests on protein and DNA respectively, indicating that mixing fungicide with 0.2% of aqueous solution of phycocyanin increase number of unaffected bands, decreasing numKey words: Phycocyanin, Anticlastogenic agent, Cytological study, Molecular study.
