Diagram of the GAANTRY 10-stack construct and phenotypes in transgenic potato plants. a Schematic representation of the GAANTRY 10 stack T-DNA. b Transgenic potato shoots rooting in media containing 100 mg/L kanamycin (observed from the bottom of the magenta box). c Red fluorescence observed in a transgenic potato leaf. d Leaf GUS activity. e Transgenic potato shoots rooting in media containing 25 mg/L sulfadiazine. f Firefly luciferase activity measured in wildtype and seven 10-stack transgenic potato plants. The red dashed line marks the level of background luminescence detectable in wildtype potato leaf samples. Wildtype potato plants do not root on kanamycin or sulfadiazine media and do not exhibit detectable red fluorescence or GUS activity under these assay conditions
