tomato, Flavr Savr, was modified by Calgene (a biotechnology company) using Flavr Savr tomatoes are designed so they can ripen on the vine longer while. Flavr Savr Tomato Disguised in the cover of a favorite summer time topic — why don’t store-bought tomatoes taste good? — The New York Times has printed a. The FLAVR SAVR™tomato was developed through the use of antisense RNA to regulate the expression of the enzyme polygalacturonase (PG) in ripening.

PG gene suppression was achieved using an antisense expression cassette of the endogenous PG gene resulting in an RNAi-mediated pathway and yielding the phenotype of the Flavr Savr tomato. RNA purification and Northern blots. It has been demonstrated repeatedly that expression of an antisense cDNA alone does not result in gene silencing as efficiently as expressing a dsRNA Stam et al.
