Figure 4. Expression of the defensin-like transgene in transformed whole tobacco plants.

(a) Agarose-formaldehyde gel stained with ethydium bromide.
(b) Northern blot analysis. Arrow indicates the expected position of the hybridization band specific for the defensin-like probe.
Total RNA from 12 independent lines (lanes 1-14) were analysed. Lanes 2, 4, and 6 – 14 were considered positive lines. NN = Control, corresponding to non transformed plants.
