Detection methods using a conventional polymerase chain reaction (PCR) were developed to detect two lines of genetically modified (GM) rice that have not been approved as safe for use in foods in Japan. Two GM rice lines were Bacillus thuringiensis (Bt) rice lines (Bt63 and NNBt) in which cry genes derived from Bt conjugated with a suitable plant expression promoter and terminator are transformed, expressing the Bt toxin protein confers a tolerance against insects. We designed primer pairs to detect the two lines of GM rice based on the common cry gene sequence. We also designed the primer pairs to specifically detect Bt63 and NNBt rice, respectively, on the sequences we had already clarified. The proposed method was applied to the detection of the two Bt rice lines in rice vermicelli and glutinous rice samples. We showed that the present conventional method was a reasonable assay for monitoring two Bt rice lines in processed rice products.
