A tomato by any other gene: Just as sweet? (+video)
New research shows that the bland flavor of a popular variety of firm tomatoes is caused by a genetic switch. Locating this switch may enable scientists to create good-tasting and good-shipping tomatoes in the future.
Using genetics, scientists have been able to dig up the dirt on why homegrown¬†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¬†tomato. A new study in Friday's edition of Science found that the common type of¬†tomato¬†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¬†tomatoes¬†that also travel well.
