The American chestnut once dominated the eastern forests of the United States. A fungal pathogen, Cryphonectria parasitica, was introduced to the US in the early 20th century and within a few decades, the pathogen now known as the chestnut blight killed an estimated 4 billion chestnut trees.
Over the last century, there have been a number of efforts to confer blight resistance and restore the chestnut, including hybridization and backcross breeding programs ….
