The Chemical Ghost: Solving the Final Mystery of Nicotine Biosynthesis
For decades, the precise chemical steps plants use to manufacture nicotine remained a mystery. Researchers have finally mapped the complete pathway, revealing a five-part molecular machine that builds and transports the potent chemical. This discovery allows scientists to engineer natural pest resistance into other plant species in the laboratory.
