The U.S. Forest Service has a long history as a leader in conservation genetics, and this recently took an exciting step forward with the launch of the National Genomics Center for Wildlife and Fish Conservation.
The Forest Service’s wildlife genetics lab, which has been central to the Rocky Mountain Research Station’s conservation genetics program since 1998, has been reorganized and renamed to better reflect the scope of its work nationwide. The Center is a leading edge facility for advanced genomics research, nationally recognized, and works extensively with states, tribes, universities and private groups to address the management issues of over 60 fish and wildlife species.

Data gathered from the AgENCODE project will ultimately improve cattle breeding.

The idea that around 80 percent of human DNA is “junk” DNA with no real purpose never sat well with scientists. So in 2003, researchers funded by the U.S. National Institutes of Health started working on a project called ENCODE, which was designed to study the role of non-coding “junk” DNA in genetic expression and to define basic functional units in the human genome.
USDA’s Agricultural Research Service (ARS) scientists are spearheading a parallel project called AgENCODE, which takes a similar approach to exploring the mechanics of DNA regulation in key livestock species. “We can identify 70 to 90 percent (or more) of the DNA coding elements in animal genomes, but we don’t know much at all about the non-coding elements,” says ARS National Program Leader Jeffrey Silverstein, who is helping to organize the AgENCODE effort. “We think many of these non-coding segments regulate gene activity, and we need to understand how these segments affect the expression of an animal’s physical traits, which is very important in breeding.” Read more »
