Re-evaluating the site-directed nuclease classification as a regulatory trigger for genome-edited plant products

Scientific research & Discovery: Discover the World Via Study and Technology

Key takeaways
  • The site-directed nuclease (SDN) classification fails as a regulatory trigger; edit outcomes, not editing method, determine biological risk.
  • Emerging tools like base editing and prime editing blur SDN1, SDN2, and SDN3 distinctions, complicating regulatory categorization.
  • Advocate for product-based regulation focused on trait-level risk assessment and science-based, proportionate oversight.
  • Current classifications hinder trade and enforcement because small edits can be indistinguishable from natural variation.
  • Harmonization across jurisdictions with transparent, evidence-based criteria will enable innovation while preserving environmental and food safety.
