Detection of Cadmium Genotoxicity on Fatty Acids Desaturase-2 Genes in Safflower (Carthamus tinctorius)

Environmental pollution negatively affects the life activities of living things environment and causes structural damages on all inanimate things. The extent damage caused by human-made to nature is increasing day day. Heavy metal one most important environmental pollution. Cadmium, which pollutants, a highly toxic not used things, even in trace amounts. Cadmium also very heavy for plants. As with other metals, it triggers oxidative stress production reactive oxygen species plant cells, causing DNA abnormalities RNA production. Safflower oil high economic value intensive use as raw material many sectors. In this study, experimental groups prepared at different cadmium concentrations, negative/genotoxic effects mRNA expression levels FAD2 (FAD2-6, FAD2-7, FAD2-11) genes, responsible conversion oleic acid linoleic safflower varieties (Balci, Bdyas-04, Linas Asol) has been determined quantitative Real-Time PCR method. result, detected that decrease firstly genes concentrations cultivars. And also, re-increase 160 320 mg L-1 can be considered critical points, have accepted an indication defense mechanism against activated play role stress. conclusion, obtained data showed cultivars only fatty acids but
