Tardigrade Admin · Accepted Answer

The tomato variety 'Flavr Savr' presents an example where expression of a native tomato gene has been blocked. Fruit softening is promoted by the enzyme polygalacturonase, which degrades pectin. Production of polygalacturonase is blocked in the transgenic tomato variety 'Flavr Savr'. So, fruits of this tomato variety remain fresh and retain their flavour much longer than do the fruits of normal tomato varieties. Additionally, the fruits have a superior taste and increased total soluble solids.
