Major breakthrough in deciphering bread wheat's genetic code
Date:11/28/2012

Scientists have unlocked key components of the genetic code of one of the world's most important crops. The first analysis of the complex and exceptionally large bread wheat genome, published today in Nature, is a major breakthrough in breeding wheat varieties that are more productive and better able to cope with disease, drought and other stresses that cause crop losses.

The identification of around 96,000 wheat genes, and insights into the links between them, lays strong foundations for accelerating wheat improvement through advanced molecular breeding and genetic engineering. The research contributes to directly improving food security by facilitating new approaches to wheat crop improvement that will accelerate the production of new wheat varieties and stimulate new research. The analysis comes just two years after UK researchers finished generating the sequence.

The project was led by Neil Hall, Mike Bevan, Keith Edwards, Klaus Mayer, from the University of Liverpool, the John Innes Centre, the University of Bristol, and the Institute of Bioinformatics and Systems Biology, Helmholtz-Zentrum, Munich, respectively, and Anthony Hall at the University of Liverpool. W. Richard McCombie at Cold Spring Harbor Laboratory, and Jan Dvorak at the Univerisity of California, Davis, led the US contribution to the project.

The team sifted through vast amounts of DNA sequence data, translating the sequence into something that scientists and plant breeders can use effectively. All of their data and analyses were freely available to users world-wide.

Professor Neil Hall said: "The raw data of the wheat genome is like having tens of billions of scrabble letters; you know which letters are present, and their quantities, but they need to be assembled on the board in the right sequence before you can spell out their order into genes."

"We've identified about 96,000 genes and placed them in an approximate order. This has made
