The recently developed genome-editing methods, from zinc finger nucleases to transcription activatorlike effector nucleases (TALENs) to CRISPR, are shaking up the debate over how to regulate genetically modified (GM) crops. Canada, for example, has stuck to its rule that a plant should be regulated as GM if a novel trait has been introduced to it, regardless of the technology used. But the U.S. Department of Agriculture has so far exempted plants altered by TALENs and CRISPR from its GM regulations. The European Union is still wrestling with the issue.
