Fig. 2From: Transgene stacking in potato using the GAANTRY systemGenomic PCR screening of the 10-stack transgenic potato plants. Seven 10-stack potato transgenic events along with water (blank; B) and wildtype (WT) negative controls, and A. rhizogenes ArPORT1 10-stack genomic DNA (positive control; P) were analyzed for the presence of the mybA (a), uidA (b), bar (c), and eGFP genes (d). e The presence of LB ‘backbone’ sequence was also examined using primers that detect sequences outside of the T-DNA left border. The expected sizes each of the PCR amplicons are shown on the right of each panelBack to article page
