So the actual range of American chestnut is much more than the 200 acres it grew on at the time of the blight. To date, the OxO gene has been inserted into a single American chestnut background, the Ellis1 tree from New York, to produce the transgenic "Darling 58" founder being reviewed by the federal regulators. University of Vermont Emeritus Professor, and others worry that approval of a transgenic chestnut would act as a Trojan . The American chestnut (Castanea dentata) was once an integral part of eastern United States deciduous forests, with many environmental, economic, and social values. For the last six years, the growing trees have been sequestered behind a high deer fence in a special field near the SUNY campus in Syracuse, closely monitored and government . Transgenic pollen was placed on the flowers of blight-susceptible mother trees, with the expectation that perhaps half of the offspring would inherit the resistance. . Plant grafted trees in moderately acidic, well-drained . Because genetically engineered plants must be approved for use by federal agencies, ESF has filed a "Petition for Determination of Nonregulated Status for Blight-Tolerant Darling 58 American Chestnut ( Castanea dentata )" with the United States Department of Agriculture's office of Animal and Plant Health Inspection Service (USDA-APHIS). The team not only found that the genetically modified trees, a variety known as Darling 58, could withstand the blight, but that the modified trees were compatible with the larger ecosystem.

They are all a mix of the varieties that we sell. Blight-tolerant American chestnut (Castanea dentata) Darling 58 cultivar is genetically engineered with an oxalate oxidase (OxO) gene from wheat intended to allow offspring that receive it to survive infections from the ascomycete fungus Cryphonectria parasitica well enough that the trees can become dominant overstory species in forests again. The trees have been developed using genetic engineering to express an oxalate oxidase enzyme from wheat as a defense In January, SUNY petitioned the U.S. Department of Agricultural for its line of Darling 58 American Chestnut trees to be given a non-regulated status. The Sierra Club writes: "Genetically speaking, Darling 58 is an entirely American chestnut with one extra gene that gives it a bonus characteristic: resistance to Cryphonectria parasitica." This is unprecedented. I'm no expert on rna, but any new genetically modified tree would have to go through a new, years long goverment approval process. Approval of the blight resistant Darling 58 American chestnut tree will bring us just a bit closer to realizing the forest dream of complex, mature Eastern hardwood forests with 200-300 year old trees standing 100-150 feet tall. .
