The genetically modified ingredients introduced including promoter,terminator,selectable marker genes and structural genes(encoding the novel protein) etc were detected with the multiplex PCR technology in order to establish a quick,exact and effective technical system of the screening of genetically modified crops.The triplex PCR of soya inner LECTIN gene,Cauliflower mosaic virus(CaMV)35S promoter and Agro-bacterium tum ef aciens nopaline synthase(NOS) terminator,and the triplex PCR of CaMV35S promoter,NPT...
