Tomato's taste: the secret is in its genome (+video)

Tomato genetics is the key to improved taste, say researchers who recently published the fruit's full genome.

For years scientists have slaved away, trying to piece together the genes that make up the ripe, red goodness that is the tomato. They have finally published the fleshy fruit's genome in full.

The genome of any species is the DNA code that is stored as a blueprint inside every cell of every individual of that species. The DNA letters, called base pairs, are organized into genes, which are translated into proteins, the building blocks and machinery of every cell.

Decoding these genes can help researchers understand the different types of proteins found in organisms, and how these proteins make that species different from every other species. These kinds of insights from the genome could help crop researchers improve the yield, nutritional content, disease resistance, taste and color of tomatoes, they say.

"For any characteristic of the tomato, whether it's taste, natural pest resistance or nutritional content, we've captured virtually all those genes," study researcher James Giovannoni, of Cornell University, said in a statement. "Tomato genetics underlies the potential for improved taste every home gardener knows and every supermarket shopper desires and the genome sequence will help solve this and many other issues in tomato production and quality."
