Back on the agricultural beat

As mentioned before, I'd like to see us do this with every agriculturally important species.

LONDON (Reuters) - An international team of scientists has cracked the genetic code of the domesticated tomato and its wild ancestor, an achievement which should help breeders identify the genes needed to develop tastier and more nutritious varieties. 
The full genome sequence of a tomato breed known as Heinz 1706, and a draft sequence for its closest wild relative Solanum pimpinellifolium, were published in the journal Nature on Wednesday.
Researchers who carried out the work said that together the sequences provide the most detailed look yet at the functional parts of the tomato genome and show order, orientation, types and relative positions of all of its 35,000 genes. 
The sequences should help researchers find the links between certain tomato genes and the characteristics they determine, and will also extend scientists' understanding of how genetic and environmental factors affect the health of a crop. 
"Tomatoes are one of the most important fruit crops in the world, both in terms of the volume that we eat and the vitamins, minerals and other phytochemicals that both fresh and processed tomato products provide to our diets," said Graham Seymour, a professor of biotechnology at Nottingham University, one of 300 scientists involved in the Tomato Genome Consortium (TGC).
"For any characteristic of the tomato, whether it's taste, natural pest resistance or nutritional content, we've captured virtually all those genes," said James Giovannoni from the Boyce Thompson Institute for Plant Research at Cornell University, who was part of the U.S. tomato sequencing team. 
Tomatoes represent a $2 billion market in the United States alone, while in Britain the market for tomatoes is worth around 625 million pounds ($980 million) a year.
