If you've been keeping up, you know that the effort to create a GM blight resistant American Chestnut has largely collapsed amid accusations of data fraud. The major funders of the project have pulled out. Also, I was surprised to read that when the blight arrived, there had already been a massive die-off of southeastern trees due to ink disease, so, even if they were to succeed in their efforts, chestnuts aren't coming back to SC unless they figure out ink disease as well.
