MetabolomicsLipidomics study for investigating the role of the Unfolded Protein Response In Arabidopsis seed filling

The Unfolded Protein Response (UPR) is a retrograde, ER-to-nucleus, signalling pathway which is conserved across kingdoms. In plants, it contributes to development, reproduction, immunity and tolerance to abiotic stress. This lipidomic dataset was produced from Arabidopsis thaliana mature seeds. ...

MetabolomicsMetabolomic Characterization of Knock-Out Mutants in Arabidopsis - Development of a Metabolite Profiling Database for Knock-Out Mutants in Arabidopsis (MeKO)
Despite recent intensive research efforts in functional genomics, the functions of only a limited number of Arabidopsis (Arabidopsis thaliana) genes have been determined experimentally. Thus, improving gene annotation remains a major challenge in plant science. Because metabolite profiling can chara...

MetabolomicsRegulatory actors and alternative routes for Arabidopsis seed germination are revealed using a pathway‐based analysis of transcriptomic datasets
Regulation of seed germination by dormancy relies on a complex network of transcriptional and post‐transcriptional modifications during seed imbibition that controls seed adaptive responses to environmental cues. High‐throughput technologies have brought significant progress in the understanding of ...

MetabolomicsMetabolic fingerprinting reveals roles of Arabidopsis thaliana BGLU1, BGLU3, and BGLU4 in glycosylation of various flavonoids

Flavonoids are specialized metabolites that play important roles in plants, including interactions with the environment. The high structural diversity of this metabolite group is largely due to enzyme-mediated modifications of flavonoid core skeletons. In particular, glycosylation with different ...

MetabolomicsEffects of MeJA on Arabidopsis metabolome under endogenous JA deficiency
Jasmonates (JAs) play important roles in plant growth, development and defense. Comprehensive metabolomics profiling of plants under JA treatment provides insights into the interaction and regulation network of plant hormones. Here we applied high resolution mass spectrometry based metabolomics appr...

MetabolomicsThe natural variance of the Arabidopsis floral secondary metabolites
Application of mass spectrometry-based metabolomics enables the detection of genotype-related natural variance in metabolism. Differences in secondary metabolite composition of flowers of 64 Arabidopsis thaliana (Arabidopsis) natural accessions, representing a considerable portion of the natural var...

MetabolomicsMetabolite profiling of Arabidopsis mutants of enzymes of lower glycolysis
We have previously shown that in Arabidopsis the three enzymes of lower glycolysis phosphoglycerate mutase (PGAM), enolase and pyruvate kinase form a complex which play an important role in co-sub-cellar localization the mitochondria to the chloroplast. Given that their metabolites of these mutants,...

MetabolomicsAccumulation of the coumarin scopolin under abiotic stress conditions is mediated by the Arabidopsis thaliana THO/TREX complex
Secondary metabolites are involved in the plant stress response. Among these are scopolin and its active form scopoletin, which are coumarin derivatives associated with reactive oxygen species scavenging and pathogen defence. Here we show that in Arabidopsis thaliana, scopolin accumulation can be in...

MetabolomicsMetabolomic correlation-network modules in Arabidopsis based on a graph-clustering approach
Deciphering the metabolome is essential for a better understanding of the cellular metabolism as a system. Typical metabolomics data show a few but significant correlations among metabolite levels when data sampling is repeated across individuals grown under strictly controlled conditions. Although ...

MetabolomicsNatural variation of root exudates in Arabidopsis thaliana-linking metabolomic and genomic data
The 19 parent lines of the Arabidopsis thaliana MAGIC collection show significant differences in their root exudate profiles. Changes in metabolism were analyzed by ultra-performance liquid chromatography coupled to electrospray ionization quadrupole time–of–flight mass spectrometry (UPLC-ESI-QTOF-M...
