This blight attacks the tree's bark, creating cankers that girdle and ultimately kill mature trees. By the mid-20th century, approximately 99% of American Chestnut trees had succumbed to the blight.

The researchers at SUNY have figured out how to move a gene from wheat into the genome of the American chestnut. It allows the trees to break down the toxins from the Asian blight. In other words ...
