Figure 5. Expression of the defensin-like transgene in tobacco plantsleaf tissue. Ethidium bromide stained agarose gel resolving the RT-PCR reactions of four of the selected positive lines shown in Figure 4 (lines 9 – 12). Lanes: 1, Pst1-digested lambda DNA; 2, no template control reaction; 3-6, positive lines 9-12; 7-8, two untransformed lines. Arrow indicates the expected amplicon size.
