Abstract: PURPOSE: To detect the exogenous gene copy number of the transgenic tomato anti-caries vaccine by using the SYBR Green real-time PCR. METHODS: Recombinant plasmid pEAC10 and pEPC10 were used as standard to detect genome samples of exogenous gene pacA-ctxB and pacP-ctxB by SYBR green fluorescent quantitation, then the average value was calculated as gene copy number. RESULTS: The copy number of the transgenic tomato carrying pacA-ctxB was 1.3 and the pacP-ctxB was 3.2. CONCLUSIONS: The transgenic tomato plants which have high stability are low-copy transgenic plants.
