students could “debate” the issue. The last resource is an UF/IFAS Extension document regarding genetically-modified tomatoes and why they are NOT being planted in Florida. 29 Now, back to our quiz. Pick the genetically modified organism (crop). 30 Only three of the nine vegetables or fruits shown in the slide can be labeled as transgenic or genetically modified organism. Rio Red Grapefruit: Grapefruit itself is a natural hybrid between sweet orange and pomelo, first observed in the Caribbean in 1700s. Rio Red was developed by mutating bud wood with thermal neutrons. Tangelo: Interspecific cross between grapefruit and tangerine. Squash: GMO;, Agrobacterium-mediated transformation in which the transfer-DNA (T-DNA) contained the coat protein genes from the targeted virus. Tomato: Selective breeding program only at this point in time. Eggplant: GMO; Agrobacterium-mediated transformation with Bacillus thuringiensis protein gene inserted to obtain resistance to a fruit and stem boring insect. The first introduction was in Bangladesh Japanese Pear: The variety “Golden Nijisseiki” was obtained by gamma radiation of the variety “Nijisseiki” to obtain resistance to black spot disease. leading Green Bean: Selective breeding program only at this point in time. Papaya: GMO; The Hawaiian cultivar “Rainbow” was obtained with the gene gun. RNA interference defends the fruit against the papaya ringspot virus. Pluots: Interspecific cross between apricot and plum.
