Signatures of selection inscribed on poplar genomes

A recent study published online August 24, 2014 in Nature Genetics offers a more in-depth, population-based approach to identifying such mechanisms for adaptation, and describes a method that could be harnessed for developing more accurate predictive climate change models. For the U.S. Department of Energy, which is developing biomass crops for biofuels production, this knowledge could determine which genotypes – genetic makeup of an organism – of biomass crop may thrive better than others in certain environments. The team led by Gerald Tuskan of Oak Ridge National Laboratory (ORNL), the Department of Energy Joint Genome Institute (DOE JGI) and Stephen DiFazio of West Virginia University, used a combination of genome-wide selection scans and analyses to understand the processes involved in shaping the genetic variation of natural poplar (Populus trichocarpa) populations.

A team of researchers, led by Professor Charles E. Wyman, at the University of California, Riverside’s Bourns College of Engineering have developed a versatile, relatively non-toxic, and efficient way to convert raw agricultural and forestry residues and other plant matter, known as lignocellulosic biomass, into biofuels and chemicals.

WUOT Interview with Jerry Tuskan on extracting jet fuel from eucalyptus plants

Dr. Tuskan was interviewed by WUOT, listener supported public radio station from the University of Tennessee in Knoxville, Tennessee which aired July 25th. 

The interview discussing the study of extracting jet fuel from eucalyptus plants can be heard at http://wuot.org/post/method-exploring-prehistoric-life-and-making-fuel-plants. (The interview begins around 3:56 into the link.)

Improving commercial viability of biofuels

Charles Wyman, A University of California, Riverside Bourns College of Engineering professor is one of the authors of a paper recently published in Science that outlines ways companies can commercialize and profit from what was thought to a waste product created when producing biofuels.

New UGA research engineers microbes for the direct conversion of biomass to fuel


The promise of affordable transportation fuels from biomass—a sustainable, carbon neutral route to American energy independence—has been left perpetually on hold by the economics of the conversion process. New research from the University of Georgia has overcome this hurdle allowing the direct conversion of switchgrass to fuel.

A Tipping Point for Lignin


Led by Art Ragauskas, the newly appointed Oak Ridge National Laboratory-University of Tennessee Governor's Chair in Biorefining, a multi-institutional team of researchers offers a new view of an organic polymer often dismissed as a worthless by-product. Their perspective appears in Science magazine as "Lignin Valorization: Improving Lignin Processing in the Biorefinery.
