The scientist is White Oak (Quercus alba), a rich forest tree species in eastern North America of ecological, cultural and economic importance.

“The Oaks are an important member of many ecosystems around the world,” said a researcher at the University of Tennessee. Meg Staton And a colleague.
“In eastern North America, white oak is a keystone species and is one of the most abundant forest trees across its range.”
“In addition to its ecological and cultural importance, white oak has a very economic importance, including many high value material applications and the main species used in barrel styles for the aging of distilled spirits. It's there.”
“However, few studies have addressed the diversity of white oak genomes. The lack of available genetic and genomic resources now creates barriers to fostering understanding of white oak biology and evolutionary history. It's presenting it.”
In their study, the authors sequenced individual genomes of white oak from a forest near Loretto, Kentucky, USA.
They found that this oak species has a high genetic diversity, many of which preceded divergence from other oaks, and likely could affect divergence time estimates .
“The White Oak genome represents a major new resource for studying genome diversity and evolution. Quercus” said Dr. Staton.
“Also, unbiased gene annotations are key to accurately assessing the evolution of R (disease-resistant) genes. Quercus. ”
“Our paper addresses the degree of genetic diversity and population differentiation in white oaks and how gene content and disease resistance genes evolved. Quercus Related species. ”
The authors say that the amount of standing genetic variation and the degree to which the population is regionally adapted will affect the response of white oaks and other oak species to increasingly common heat and drought stress. It points out.
“The details are interesting for those who are invested in the sustainability of White Oak, across economic, ecological and cultural boundaries,” they said.
