UC Davis researchers aid effort to sequence the complex wheat genome
Date:11/28/2012

hii sequence with modern wheat allows researchers to assess genomic changes that have taken place in bread wheat since its origin approximately 8,000 years ago.

In the study reported in Nature, the researchers used the whole genome "shotgun sequencing" approach, which generates billions of random genome sequence "reads" and then pieces them together. The results provide information about the DNA making up wheat genes that will help wheat breeders develop hardier varieties by linking genes to key traits, such as disease resistance and drought tolerance.

"This sequencing effort has yielded important information that will accelerate wheat genetics and breeding and help us better understand wheat evolution," Dvorak said. "It cannot be overemphasized, however, that this is just one step in the global effort to produce a high-quality draft of the bread wheat genome sequence."

He said completion of such a high-quality genome sequence for bread wheat is still a few years away and will require broad international collaboration to complete.
