This is an update on the American Chestnut Restoration Project, as discussed previously on the podcast. The American Chestnut dominated the forests of Appalachia until an imported fungus destroyed the entire range. Efforts to restore the chestnut and its ecology have employed a biotechnology approach, integrating a gene from wheat that limits the mechanism the fungus uses to attack the tree. Dr. Andy Newhouse and Erik Carlson join the podcast to discuss progress in the project.
