A tomato by any other gene: Just as sweet?
| WASHINGTON
Using genetics, scientists have been able to dig up the dirt on why homegrown聽tomatoes taste so much sweeter than the ones in the supermarket.
Researchers found a genetic switch responsible for some of the sugar production within a聽tomato. A new study in Friday's edition of Science found that the common type of聽tomato聽bred for firmness and good shipping also inadvertently turns off the sugar-producing switch. That makes it less sweet and blander than garden varieties.
University of California Davis plant scientist Ann Powell said knowing the genetics behind the sugar-making could lead someday to development of sweeter聽tomatoes聽that also travel well.
