Plum trees with resistance to plum pox (PPV), a virus that can devastate stone fruit, have moved a step closer to reality, according to the Agricultural Research Service (ARS), which is leading the project. The U.S. Department of Agricultures Animal and Plant Health Inspection Service (APHIS), which has regulatory authority over genetically engineered organisms, recently deregulated HoneySweet, as the PPV-resistant plum tree is named. This means APHIS had determined that the tree is not a plant pest and that it will have no significant impact on other plants.
