The New American Chestnut


Monday, April 17, 2017, 7:00pm to 8:30pm


Hunnewell Building

Much work has gone into attempting to bring back the American chestnut (Castanea dentata), decimated by the exotic chestnut blight fungus (Cryphonectria parasitica) beginning in the late 1800s. Breeding by crossing and back-crossing with Japanese and Chinese species has produced positive results, but genetic engineering is proving more viable. William A. Powell, involved in transgenic research that has produced a tree that is 99.999% American chestnut, will speak about this work and the possibilities for reviving a species once ubiquitous in eastern North American forests.
