- Researchers from Michigan State University and the Czech Academy of Sciences tracked thousands of genes across wolfsbane and larkspur species to identify six enzymes that assemble atisinium, a diterpenoid alkaloid with potential uses against pain, malaria, cancer, and agricultural pests.
- The team transferred the genetic instructions into tobacco plants, which successfully produced atisinium — recreating the source plants' chemistry outside the original species for the first time.
- The six enzymes added an unexpected nitrogen source to the molecule, shaping it into its complex final structure in a step co-first author Garret Miller said the researchers had not anticipated.
- The collaboration began when Björn Hamberger met researchers from Tomáš Pluskal's lab at a scientific conference in Barcelona, where both groups discovered they were independently studying the same diterpenoid alkaloid family.
- Published in Molecular Plant, the findings address a puzzle dating back nearly 200 years — closely related aconitine was isolated long ago but has never been successfully synthesized in a laboratory.
Why it matters: The work gives pharmaceutical researchers a scalable route to produce diterpenoid alkaloids — a compound class that has resisted lab synthesis for roughly 200 years — potentially unlocking new painkillers, anti-malarial treatments, cancer therapies, and pesticides without harvesting rare and lethal source plants.
