Induced Furoeudesmanes: A Defense Mechanism Against Stress in Laggera pterodonta, a Chinese Herbal Plant

Laggera pterodonta displays different phenotypes in its natural habitat but expresses a uniform phenotype with large, broad leaves and fewer secondary metabolites when grown under optimal conditions. The production of six furoeudesmanes is only induced when L. pterodonta encounters stresses, conferring host resistance against a broad spectrum of plant invaders.
