american Scientists found the genetic changes that allow you to retrieve the original taste, lost in the past 50 years
those Who runs typically the vegetable markets, well-known to tomatoes “industrial” no longer have the same taste that some years ago. That, finally, could be solved thanks to the work of a team of american researchers who identified the varieties genetic that allow you to restore the original taste.
“Let’s recover the taste of the tomatoes lost in the course of the last few decades,” says Harry Klee, a professor of horticulture at the University of Florida, who led the study. The scientist promises to “be able to do much better the tomatoes of the supermarket.”
One of the first stages of his work, published yesterday in the journal of american Science, was to determine which chemicals contribute to making tasty tomatoes.

The varieties of industrial current does not contain enough sugar or substances essential for flavor, says the scientist.
Half a century of tomatoes tasteless
These qualities have been lost in the course of the last fifty years, because the producers did not have the scientific tools necessary to regularly check the taste of their tomatoes, he explains.
Working on the genome of the tomato, which was completely sequenced in 2012, the researchers were able to identify changes in five or six genes that control the synthesis of all the chemicals important to give the taste to this fruit.
Later replaced in the genome of tomatoes for industrial genetic variations bad for those that will provide the flavor.
In three or four years
But as well as the creation of a new variety takes time, scientists estimate that it will take three or four years to produce the new tomatoes with flavor.
the united States is the world’s second largest producer of tomatoes behind China, according to the u.s. Department of Agriculture (USDA).
