MetabolomicsComparison of singlequad and Orbitrap mass analyzer coupled to gas chromatography reveals potential of high resolution GC MS for untargeted metabolomics

The development of improved spectrometers and supporting computational tools is expected to eventually enable the rapid annotation of whole metabolomes. However, rarely are novel mass spectrometers directly compared to the previously used ones in the field of metabolomics, thus preventing researc...

MetabolomicsSeagrass excretes sugars to their rhizosphere making them the sweet spots in the sea (Seawater sediment; GC-MS assay)

Seagrasses are one of the most efficient natural sinks of carbon dioxide (CO2) on Earth. Despite covering less than 0.1% of coastal regions, they have the capacity to bury up to 10% of marine organic matter and can bury the same amount of carbon 35 times faster than tropical rainforests. On land,...

MetabolomicsA large-scale metabolomics study to harness chemical diversity and explore biochemical mechanisms in ryegrass (UPLC-MS C1 reverse phase POS and GC-MS FAME assays)
Perennial ryegrass (Lolium perenne) is integral to temperate pastoral agriculture, which contributes most of the milk and meat production worldwide. Chemical profiles and diversity of ryegrass offer several opportunities to harness specific traits and elucidate underlying biological mechanism...

MetabolomicsThe genomic and enzymatic basis for iridoid biosynthesis in cat thyme (Teucrium marum)
Iridoids are non-canonical monoterpenoids produced by both insects and plants. An example is the cat attracting and insect repelling volatile iridoid nepetalactone, produced by Nepeta sp. (catmint) and aphids. Recently, both nepetalactone biosynthetic pathways were elucidated, showing a remarkable c...

TranscriptomicsCaenorhabditis sex-specific RNAseq
This project defines the transcriptomes of XO (male) and XX (female or mutant pseudo-female) Caenorhabditis nematodes. The data allow the overall composition and sexual regulation of the transcriptome within a single species to be determined. In addition, the five related species studied allow meta-...

MetabolomicsPlant-to-plant variability in root metabolite profiles of 19 Arabidopsis thaliana accessions is substance-class dependent
Natural variation of secondary metabolism between different accessions of Arabidopsis thaliana has been studied extensively. In this study, we extended the natural variation approach by including biological variability and analyzed root metabolic patterns as well as their variability between plants ...

TranscriptomicsMultiple insert size paired-end sequencing for deconvolution of complex transcriptomes
Deep sequencing of transcriptomes allows quantitative and qualitative analysis of many RNA species in a sample, with parallel comparison of expression levels, splicing variants, natural antisense transcripts, RNA editing and transcriptional start and stop sites the ideal goal. By computational model...

MetabolomicsHeadspace volatile organic compounds from bacteria implicated in ventilator-associated pneumonia analysed by TD-GC/MS
Ventilator-associated pneumonia (VAP) is a healthcare-acquired infection arising from the invasion of the lower respiratory tract by opportunistic pathogens in ventilated patients. The current method of diagnosis requires the culture of an airway sample such as bronchoalveolar lavage, which is invas...
