The increased areas under cultivation of genetically modified plants have proponents and opponents in the international arena. According to potentially usefulness and harms of these products, organizations have established regulatory rules to safety use of them for feeding humans and livestock. Hence, genetically modified products have been distinguished from non-GMOs through labeling. Two more applicable genetic elements in plant transformations, 35S promoter and nos terminator, were considered as targeted elements for detection of GMO products in this research. Three maize grain cultivars, one soybean meal sample, and three bird’s food samples were used as experimental materials. The two-targeted genetic elements were detected in all samples. The Invertase and Lectin sequences as endogens were used for determining the presence of corn and soybean genomes as criteria. The two endogens were identified in all those of samples, which have the related genomes. In accordance to accepting of Cartagena Protocol in Iran, it’s been hopped that labeling rules of GMO products follow more seriously.
