One of the saddest environmental stories has been the fungal blight that destroyed millions of American chestnut trees in the first half of the 20th Century. But now, according to the New York Times, two research groups may be closing in on a long-sought solution. The first group from the American Chestnut Foundation is planting 14,000 seedlings of a Chinese-American hybrid chestnut atop reclaimed strip mines in Pennsylvania that could be resistant to the killer blight. The other is a group of geneticists in Syracuse, NY, who are using a gene from wheat to help chestnuts produce a blight-fighting enzyme. Here’s hoping these developments sprout a long-term solution to the hard-shelled problem with chestnuts.
