Oak Ridge Lab Confirms Blight Resistance of American Chestnut

American chestnut

Researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), working collaboratively with scientists funded by The American Chestnut Foundation, have helped confirm that addition of a wheat gene increases the blight resistance of American chestnut trees.

The ORNL team, in collaboration with foundation researchers led by Drs. William Powell and Chuck Maynard of ESF, used gas chromatography-mass spectrometry to analyze chestnuts from transgenic American chestnut trees-trees that were transformed with a wheat gene to increase resistance to blight. Results also showed that the transgenic chestnuts had similar metabolite concentrations to a panel of non-transgenic nuts, suggesting that they are edible.
