Fig. 3. The level of recombinant RSV-F protein in fruit of different tomato plants. Tomato plants were transformed with a construct carrying the RSV-F antigen gene driven by either the CaMV 35S promoter (plasmid pJSS-3) or the E-8 fruit-specific promoter (plasmid pJSS-4). Untransformed tomato plant used as control.
