MetabolomicsNavigating natural variation in herbivory-induced secondary metabolism in coyote tobacco populations using MS/MS structural analysis
Natural variation can be extremely useful in unraveling the determinants of phenotypic trait evolution but has rarely been analyzed with unbiased metabolic profiling to understand how its effects are organized at the level of biochemical pathways. Native populations of Nicotiana attenuata, a wild to...

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...

MetabolomicsIlluminating a plant’s tissue-specific metabolic diversity using computational metabolomics and information theory
While cross-tissue metabolite variations are increasingly regarded as important readouts of tissue-level gene regulatory processes, these have rarely been explored by non-targeted metabolomics. Here we explore tissue-level metabolic specialization in Nicotiana attenuata, an ecological model with ric...

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...

TranscriptomicsTissue specific diurnal rhythm of transcripts and their regulation during herbivore attack in Nicotiana attenuata
Idenfication and characterization of oscillating transcripts after elicitation with oral secretions from the sepcialist herbivore, Manduca sexta larvae Source leaves, sink leaves and roots were collected every 4 h for one days.
