Evidence for integration of foreign genes in transgenic tobacco plants. (A). Southern blot detection of the E.coli gcl gene in T2 transgenic lines. Genomic DNA from T2 plants was cut with either HindIII or EcoRI and probed with a gcl digoxygenin-labeled probe. Approximate sizes are indicated in bp. (B). Southern blot detection of the E.coli hyi gene in T2 transgenic lines. Genomic DNA from T2 plants was cut with HindIII and EcoRI and probed with a hyi digoxygenin-labeled probe. Approximate sizes are indicated in bp.
