Have you ever eaten a perfectly ripe tomato and wondered why you even bother? Tomatoes are a staple in sandwiches and salads, and you can throw them into just about any dish and come up with something edible. Tomato flavor, however, has apparently been going downhill for a while now, and scientists think they know why.

In a new study published in Nature Genetics, researchers including those from the Agricultural Research Service and the Boyce Thompson Institute have mapped the genome of the modern cultivated tomato as well as tomatoes that still grow in the wild. The team marked thousands of genes that were previously unknown, comparing the genomes of cultivated tomatoes with their wild relatives, and made more than a few interesting discoveries.

Stop & Shop announces tentative agreements, ending strike

Stop & Shop announces tentative agreements, ending strike It’s an Easter and Passover miracle. According to a statement from Shop & Shop, the grocery chain “has reached fair new tentative agreements with UFCW Locals 328, 371, 919, 1445 and 1459, which represent our 31,000 associates in Massachusetts, Connecticut and Rhode Island.” The company said it will be happy to see its employees return to work “as the strike has ended.” Stop & Shop said they are three-year agreements, subject to ratification votes by members of each local union. These agreements include: increased pay for all associates and continued health coverage for eligible associates. They also include pension benefits for all eligible associates.

After exhaustive studies, an international team of scientists has worked out why tomatoes don ’ t taste like they used to.

In comparing the cultivated tomatoes to their wild counterparts the researchers noted literally thousands of genes which were missing from the produce we typically find in our supermarkets. In the never-ending quest to develop plants that produce bigger tomatoes at a faster rate, growers seem to have inadvertently favored plants that also produce inferior-tasting fruit.

“One of the most important discoveries from constructing this pan-genome is a rare form of a gene labeled TomLoxC, which mostly differs in the version of its DNA gene promoter,” James Giovannoni, co-author of the paper, said in a statement. “The gene influences fruit flavor by catalyzing the biosynthesis of a number of lipid (fat)-involved volatiles – compounds that evaporate easily and contribute to aroma.”

Grocery store tomatoes no longer have any taste . There are scientists working to save grocery store tomatoes — and not just by encouraging people to garden or shop farmers markets. Those are the growers who can pick tomatoes once they've ripened on the vine, and they don ' t have to ship

Why supermarket tomatoes taste like cardboard. A single gene mutation Eventually, the findings could help breeders put more satisfying flavor profiles back into everyday grocery store tomatoes . Scientists have known for a long time that two GLK proteins in the leaves of tomato and other plants

Based on their own testing, the researchers believe that the flavor-enhancing gene is only present in around two percent of modern store-bought tomatoes, but was found in over 90 percent of wild tomatoes.

Making cultivated tomatoes taste great again will take some time, but some careful breeding could bring back some of the important flavor-producing genes that the plants lost since they were first domesticated.
