MetabolomicsMetabolomics study for investigating chronic endoplasmic reticulum stress in Arabidopsis thaliana

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 metabolomic dataset was produced from 14-day-old Arabidopsis thaliana s...

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...

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...

MetabolomicsA multi-omics approach to unravel the interaction between heat and drought stress in the Arabidopsis thaliana holobiont
The impact of combined heat and drought stress was investigated in Arabidopsis thaliana and compared to individual stresses to reveal additive effects and interactions. A combination of plant metabolomics and root and rhizosphere bacterial metabarcoding were used to unravel effects at the plant holo...

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 ...

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. ...

MetabolomicsMetabolic signatures of Arabidopsis thaliana abiotic stress responses elucidate patterns in stress priming, acclimation, and recovery

Temperature, water and light are 3 abiotic stress factors that have major influences on plant growth, development and reproduction. Plants can be primed by a prior mild stress to enhance their resistance to future stress. We used an untargeted metabolomics approach to examine Arabidopsis thal...

MetabolomicsUnbiased characterization of genotype-dependent metabolic regulations by metabolomic approach in Arabidopsis thaliana
Metabolites are not only the catalytic products of enzymatic reactions but also the active regulators or the ultimate phenotype of metabolic homeostasis in highly complex cellular processes. The modes of regulation at the metabolome level can be revealed by metabolic networks. We investigated the me...

MetabolomicsMetabolomics study for investigating the specific role of INOSITOL-REQUIRING ENZYME 1A and INOSITOL-REQUIRING ENZYME 1B under chronic endoplasmic reticulum stress in Arabidopsis thaliana

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 metabolomic dataset was produced from 14-day-old Arabidopsis thaliana s...

MetabolomicsStress-related mitogen-activated protein kinases stimulate the accumulation of small molecules and proteins in Arabidopsis thaliana root exudates
A delicate balance in cellular signaling is required for plants to distinguish mutualist from parasitic organisms in its environment. Mitogen-activated protein kinase (MAPK) cascades are one of the signaling modules that mediate transduction of extracellular microbial signals into appropriate cellul...
