"American Chestnut Foundation is No Longer Supporting Development of D58 Transgenic Chestnut Tree Line" would be a better title.

This is a disappointing result as the D58 line appears to have problems described in the article. However, it seems that multiple parallel efforts are ongoing with other transgenic attempts as well as more traditional back-cross methods. The road to American Chestnut restoration appears to have encountered a significant setback but promising research is still ongoing.

Relatedly, I saw many American Chestnut trees on the Shawangunk Ridge over the summer. Several were blooming. Not sure whether they bore fruit (chestnuts). This is not uncommon. Of course, they eventually become blighted and die, but they can still attain a respectable size (20-30 feet?)
