The technique used in the production of Flavr Savr tomato is ___.

Flavr Savr tomato:

1. Flavr Savr tomato is a genetically modified tomato.
2. It is the first commercial genetically engineered food.
3. Flavr Savr tomato shows delay in ripening.
4. This feature is due to the introduction of antisense RNA.
5. This antisense RNA suppresses the production of the enzyme polygalacturonase.
6. Polygalacturonase is responsible for the degradation of pectin, present in the cell wall of the fruit.
7. As a result, it softens and makes the fruit susceptible to fungal infections.
8. But, due to genetic engineering, the genetically modified Flavr Savr tomato has an extended shelf life with a reduced ripening rate.

Final answer: The technique used in the production of Flavr Savr tomato is genetic engineering.
