Title: America's Threatened Forests and Restoring The American Chestnut
Abstract: Almost one sixth of the tree species found in American forests are under severe threats due to climate change, invasive species and infections. Examples include Dutch Elm Disease, Emeral Ash Borer and notably the American chestnut which is described as being functionally extinct. The American chestnut population has been decimated by a fungus that produces oxalic acid. This toxin eventually kills the tree. Scientists have developed a blight-tolerant tree known as the Darling 58 chestnut. These trees have the complete American chestnut genome plus an additional gene that encodes for an enzyme that neutralizes the acid. This allows them to survive the infection. The Darling 58 serves as a model that illustrates how science can preserve and enhance plants, including agricultural commodities, that are threatened by climate change and disease.
