Jasmonate and ppHsystemin Regulate Key Malonylation Steps in the Biosynthesis of 17-Hydroxygeranyllinalool Diterpene Glycosides, an Abundant and Effective Direct Defense against Herbivores in Nicotiana attenuata[W]

摘要

This study describes the biosynthetic dynamics of diterpene glycosides abundant in a wild tobacco and highlights glycosylation and malonylation as key biosynthetic steps producing the diversity of compounds observed. It shows that plants silenced in diterpene glycoside production suffered more damage from herbivores in their natural habitat and were higher-quality food for a specialist herbivore.
