This white oak (Quercus alba) in Burlington, N.J. is known as the Keeler Oak. It is an estimated 300 years old and is emblematic of the role these massive trees can play in the forest and beyond. The white oak is a highly valuable tree, both economically and ecologically. Its seedling survival rate is declining, but University of Tennessee researchers joined others to map the species’ DNA.  Wikipedia Commons

New research involving University of Tennessee describes the genome of the mighty white oak

Patricia McDaniels is news and information manager for the University of Tennessee Institute of Agriculture.

KNOXVILLE — Highly valued economically, ecologically and culturally, the white oak (Quercus alba) is a keystone forest species and is one of the most abundant trees across much of eastern North America. It also faces declining seedling recruitment in many parts of its range.

In a paper published in New Phytologist, researchers representing the University of Tennessee Institute of Agriculture, Indiana University, the University of Kentucky, the U.S. Forest Service and several more institutions described for the first time the species’ complex genome, providing insights into fundamental questions about plant evolution, tree breeding and genetic improvement efforts that could help forest managers plan for and address future forest resources.

Lead authors of the paper Meg Staton, associate professor of bioinformatics and computational genomics in the UT Department of Entomology and Plant Pathology, and Drew Larson, National Science Foundation postdoctoral fellow at Indiana University, coordinated with colleagues across the nation in academia, the U.S. Forest Service, state forests and industry to obtain genetic sequence data representative of the species.

Also central to the effort were Seth DeBolt, professor of horticulture and director of the James B. Beam Institute for Kentucky Spirits at the University of Kentucky, and Dana Nelson of the U.S. Forest Service Southern Research Station and director of the Forest Health Research and Education Center at the University of Kentucky.

White oak barrels are lifeblood to the bourbon industry because the color and much of the whiskey’s flavor derive from the charred wood in which it is aged.
