What was a major reason the Flavr Savr tomato did not stay in the market?

What are the steps in the Flavr Savr tomato process?
Procedure involves: – 1) Isolation of DNA from tomato plant that encodes the enzyme polygalacturonase (PG). 2) Transfer of PG gene to a vector bacteria and production of complementary DNA (cDNA) molecules. 3) Introduction of cDNA into a fresh tomato plant to produce transgenic plant.
Why does Flavr Savr tomato have longer shelf life?
The flavr savr tomato is a transgenic tomato which is no longer able to produce polygalacturonase, so cells of the tomato remain intact and the tomato remain firm and have more shelf life.
