Figure 2. Transgenic plant morphology
A. The expression cassette shown in Figure 1 was cloned into the disabled A. tumefaciens LBA4404 strain by triparental mating. The resultant recombinant strain was used to infect Nicotiana tabacum leaf disks. Transgenic disks produced calli on kanamycin-selective medium. Shoots from calli were excised and transferred to fresh selective medium and allowed to develop into full plants as shown here.
B. Detail of roots. Note rooted and non-rooted phenotypes; the latter is non-recombinant.
