Summary

Story summary

Zhai et al. identified the complete biosynthetic pathway of acetophenones, focusing on picein in pears.
Loss-of-function mutations in the ?-oxidative pathway cause metabolic reprogramming, producing acetophenones non-enzymatically.
This challenges the notion that metabolic diversity stems only from new enzyme functions, highlighting genetic loss as a driver of innovation.
The study underscores peroxisomes' roles in catabolism and metabolic innovation, suggesting biotechnological applications for crop enhancement.
Future research may investigate similar pathways in other plants, broadening knowledge of secondary metabolites.
