MetabolomicsUntargeted metabolomic profiling reveals lineage-associated chemical divergence in Ophiorrhiza sensu lato
This study performed untargeted LC–MS metabolomic profiling of fresh leaf tissues from seven representative Ophiorrhiza sensu lato taxa: O. subpunicea, O. cantonensis, O. pumila, O. shiqianensis, O. humilis, O. huanjiangensis, and O. hispidula. Metabolites were extracted using a methanol–acetonitril...

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...

MetabolomicsImmune Stimulation via Wounding Alters Chemical Profiles of Adult Tribolium castaneum
Group-living individuals experience immense risk of disease transmission and parasite infection. In social and in some non-social insects, disease control with immunomodulation arises not only via individual immune defenses, but also via infochemicals such as contact cues and (defensive) volatiles t...

MetabolomicsMatrix Effect on Chemical Isotope Labeling and Its Implication in Metabolomic Sample Preparation for Quantitative Metabolomics
Matrix effect from various constituents in biological samples can reduce the accuracy of quantitative metabolomics. Differential chemical isotope labeling liquid chromatography mass spectrometry (CIL LC-MS) can overcome the matrix effect on MS detection based on measuring the intensity ratios of met...

MetabolomicsThe effect of changing haylages of differing chemical composition on the equid metabonome
Rapid changes between feeds can cause dysbiosis and colic. The metabolic consequences of changing between haylages is currently unknown. Objectives Characterise urinary and faecal metabonomics in ponies transitioned between haylages varying in botanical composition and physiological age and to deter...

MetabolomicsSponge exhalent seawater contains a unique chemical profile of dissolved organic matter
Sponges are efficient filter feeders, removing significant portions of particulate and dissolved organic matter (POM, DOM) from the water column. While the assimilation and respiration of POM and DOM by sponges and their abundant microbial symbiont communities have received much attention, there is ...

MetabolomicsPlot diversity differentially affects the chemical composition of leaves, roots and root exudates in four subtropical tree species

Plants produce thousands of compounds, collectively called the metabolome, which mediate interactions with other organisms. The metabolome of an individual plant may change according to the number and nature of these interactions. We tested the hypothesis that tree diversity level affects the met...

MetabolomicsTraditional Aboriginal Preparation Alters the Chemical Profile of Carica papaya Leaves and Impacts on Cytotoxicity towards Human Squamous Cell Carcinoma
Carica papaya leaf decoction, an Australian Aboriginal remedy, has been used widely for its healing capabilities against cancer, with numerous anecdotal reports. In this study we investigated its in vitro cytotoxicity on human squamous cell carcinoma cells followed by metabolomic profiling of Carica...
