Convergent biosynthesis of insect molting hormones in plants
Insect herbivores have driven plants to evolve complex chemical defenses, including mimics of the arthropod molting hormone 20-hydroxyecdysone (20E). Many distantly related plants produce 20E, suggesting multiple, independent evolutionary origins. However, despite the prevalence of 20E in arthropods and plants, complete biosynthetic pathways have remained elusive. Here, we combine genomics, gene…
