MetabolomicsDetailed Profiling of 17-Hydroxygeranyllinalool Diterpene Glycosides from Nicotiana Species Reveals Complex Reaction Networks of Conjugation Isomers

Background: Specialised anti-herbivory metabolites are abundant in the solanaceous genus Nicotiana. These metabolites include the large family of 17-hydroxygeranyllinalool diterpene glycosides (HGL-DTGs). Many HGL-DTGs occur exclusively within the Nicotiana genus,...

MetabolomicsSpecific decorations of 17-hydroxygeranyllinalool diterpene glycosides solve the autotoxicity problem of chemical defense in Nicotiana attenuata
The native diploid tobacco Nicotiana attenuata produces abundant, potent anti-herbivore defense metabolites known as 17-hydroxygeranyllinalool diterpene glycosides (HGL-DTGs) whose glycosylation and malonylation biosynthetic steps are regulated by jasmonate signaling. To characterize the biosyntheti...

MetabolomicsBotanical collections as an opportunity to explore nature through the time: An untargeted metabolomic study in historical and modern Nicotiana leaves

The living and dried specimens in botanical collections play an important role in society for scientific and recreational purposes, offering the opportunity to obtain both macroscopic and molecular information for individual plants, ecosystems, and environmental studies. Untargeted metabolomics i...

MetabolomicsMulti-omics analyses reveal regulatory networks underpinning metabolite biosynthesis in Nicotiana tabacum

Tobacco is a significant industrial crop, serving as a model for plant science and a promising specie for the production of proteins and small molecules. However, system biology studies of tobacco under natural field cultivation conditions remain scarce. Here, we construct a genome-scale metaboli...

MetabolomicsDevelopment and validation of a liquid chromatography-electrospray ionization-time-of-flight mass spectrometry method for induced changes in Nicotiana attenuata leaves during simulated herbivory
Metabolite profiling of herbivory-induced changes in Nicotiana attenuata was used to construct a correlation-weighted network to visualize intra- and inter-compound spectra relationships from individual mass features, and to annotate 12 major network hubs, including 4 O-acyl sugars and 6 17-hydroxyg...

MetabolomicsPhytohormone profiling in Nicotiana benthamiana leaves upon mechanical damage and whitefly infestation

Jasmonic and salicylic acids are the major hormones involved in plant response to pests and pathogens. Non-invasive imaging of these hormones at the tissue and whole-organism levels has remained challenging. Here, we engineer autoluminescent plants that report activity of salicylic and jasmonic a...
