Genetic behavior reveals cause of death in poplars essential to ecosystems, industry

Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic
mechanism responsible for the species' inability to resist a pervasive and deadly disease. Their finding, published in the Proceedings of the National Academy of Sciences, could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.
A research team -- jointly led by the Department of Energy's Oak Ridge National Laboratory and Oregon State University in partnership with the DOE Joint Genome Institute and the University of Georgia -- analyzed the genetic response of purebred black cottonwood poplars infected by a pathogen known as Septoria.
