The American chestnut was a dominant tree in many forests in the eastern United States. In the late 1800's an imported fungus spread rapidly throughout the range, destroying most of the trees in a matter of decades. Scientists at the State University of New York have engineered trees to host a gene from wheat that disarms the fungal invader, breaking the production of an acid required for infection. This strategy allows the tree and the fungus to live together without infection. Erik Carlson discusses the problem, the project, the push back and the current deregulation efforts to release the tree in the interest of repatriating its native range.
