[A detection method of recombinant DNA from genetically modified potato (NewLeaf Plus potato) and detection of NewLeaf Plus potato in snack].

A detection method using polymerase chain reaction (PCR) was developed to detect the genetically modified (GM) potato (NewLeaf Plus potato; NL-P), which has not been authorized as safe in foods in Japan. The potato sucrose synthase gene was used as an internal control. The DNA from NL-P specifically provided an amplified band using PCR with a primer pair recognizing PLRV-rep gene.
