The Flavr Savr variety of Tomato is a genetically modified variety that was specifically engineered to have a longer shelf life and remain fresh for an extended period. This improvement is attributed to the reduced activity of polygalacturonase, an enzyme responsible for the breakdown of pectin, a component of the cell walls in tomatoes. By having minimal polygalacturonase activity, the Flavr Savr variety can maintain its firmness and texture for a longer duration compared to non-modified tomatoes.

Therefore, option 1 is the correct answer which states that the Flavr Savr variety has little polygalacturonase, which accurately reflects the characteristic that contributes to its prolonged freshness.
