# USDA deregulates genetically engineered American chestnut to fight blight, but restoration doubts remain

USDA deregulated Darling 54, a genetically engineered American chestnut resistant to blight, though researchers question its long-term viability.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) deregulated Darling 54, a genetically engineered American chestnut variety, in late August 2026, determining it is unlikely to pose a greater plant pest risk than nonmodified trees. [^1]

Andrew Newhouse, director of ESF's American Chestnut Research and Restoration Project, said in a statement that Darling chestnuts tolerate blight better than any other fully American chestnuts they've tested and can help restore ecological relationships lost to the disease. [^2]

Darling 54 was developed by researchers at the State University of New York College of Environmental Science and Forestry (ESF) by adding a gene from wheat that expresses oxalate oxidase, an enzyme that degrades the oxalate produced by the chestnut blight fungus. [^3]

The American Chestnut Foundation (TACF) withdrew its support of the ESF project in 2023, stating in comments to APHIS that the introduced wheat gene disrupted another gene, resulting in reduced growth and survival rates of the modified trees, and that the trees have not been tested long enough to determine long-term blight resistance. [^4]

Data centers need large amounts of power around the clock, making reliable generation a premium, and they are uniquely able to pay high prices for electricity. [^5]

More than 70% of Americans oppose the construction of data centers, and 10 times as many Americans told Pew Research that data centers are bad for the environment than said they are good for the environment. [^6]

Surging growth in electricity demand historically has accelerated the deployment of clean electricity-generation technology, as seen in the golden age of nuclear energy in the U.S. in the 1960s and 1970s. [^7]

The massive data center build-out may prove to be the critical platform for commercializing clean, reliable, low-carbon electricity-generation technology that the world will need to tackle climate change. [^8]
