2024年2月27日 · Researchers have been working to bring them back, but, a genetically modified chestnut program hit a snag last year, leaving many chestnut fans wondering, what’s next? A few miles from...

2022年12月2日 · A genetically modified American chestnut has been developed to resist a deadly blight. Some say it would open the door to more GMO trees.

2024年5月3日 · More than a century ago, the American chestnut (Castanea dentata) was a common overstory tree across portions of eastern North American forests. These giants thrived on moist, well drained slopes and ridges across the Appalachians, towering more than 100 feet tall with an average diameter at breast height (DBH) of five to eight feet.

Researchers are using science to try and discover a way to revive these majestic trees. A team at the State University of New York created a Chestnut Tree that is blight resistant using genetic engineering technology. A wheat gene was introduced …

2024年10月23日 · But the self-­proclaimed “nutheads” believe the reintroduction of a GMO, blight-resistant American chestnut at scale could also become a model for how environmentalists can redeploy trees in...

2024年3月8日 · They found a way to insert a gene from wheat into an American chestnut—supposedly making it resistant to the blight. But recently, the American Chestnut Foundation announced they’re no longer supporting the Darling GMO project.

2023年4月28日 · The rapid decimation of the American chestnut kicked off a race to protect and restore it to its former glory. The first attempt involved breeding it with Asian chestnut tree species that have a natural blight resistance, but that effort took nearly three decades to consistently maintain resistance. Also, those hybrids faced additional ...

2019年4月24日 · Using a gene taken from wheat, scientists have successfully bred a lineage of American chestnut trees that tolerates the blight, and they hope to someday release it into the wild. If approved by...

2022年3月2日 · Scientists appear to have the technical capability to bring back a tree that we humans had almost driven to extinction — the American chestnut. Should they be given the go-ahead to do so? Follow...

2019年11月6日 · Researchers at the State University of New York's College of Environmental Science and Forestry will soon seek federal clearance to distribute thousands of modified trees as part of a restoration...
