MetabolomicsCommon mycelial network modulates neighbour-primed plant defences against foliar pathogens by co-opting distinct inter-plant metabolic and biotic stress responses
This study contains raw and processed mass spectrometry-based metabolomics data from Medicago truncatula plants used to investigate inter-plant signalling through arbuscular mycorrhizal fungal common mycelial networks. The experiment examined metabolomic responses in receiver plants following stress...

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...

MetabolomicsCoordinate Regulation of Metabolite Glycosylation and Stress Hormone Biosynthesis by TT8 in Arabidopsis
Secondary metabolites play a key role in coordinating ecology and defense strategies of plants. Diversity of these metabolites arise by conjugation of core structures with diverse chemical moieties, such as sugars in glycosylation. Active pools of phytohormones, including those involved in plant str...

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...

MetabolomicsNontargeted and targeted metabolomics measurements of abiotic stress responses in three-week-old Arabidopsis thaliana plants' rosette leaf tissue
Nontargeted and targeted metabolomics measurements of abiotic stress responses in three-week-old Arabidopsis thaliana plants' rosette leaf tissue for Col-0 wild type plants and double/triple knockout mutants of aquaporins (pip2;1 pip2;2 and pip2;1 pip2;2 pip2;4) treated with drought, heat at differe...

MetabolomicsSnail reprograms glucose metabolism by repressing PFKP allowing cancer cell survival under metabolic stress
Dynamic regulation of glucose flux between aerobic glycolysis and the pentose phosphate pathway (PPP) during epithelial-mesenchymal transition (EMT) is not well-understood. Here we show that Snail (SNAI1), a key transcriptional repressor of EMT, regulates glucose flux toward PPP, allowing cancer cel...

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...

GenomicsWidespread Dynamic DNA Methylation in Response to Biotic Stress
Regulation of gene expression by DNA methylation is crucial for defining cellular identities and coordinating organism-wide developmental programs in many organisms. In plants, modulation of DNA methylation in response to environmental conditions represents a potentially robust mechanism to regulate...

MetabolomicsAssessment of phenotypic trait plasticity in the oilseed Camelina sativa using integrated early-stage abiotic stress and field studies

Connecting the characterisation of juvenile (pre-anthesis) plant stress responses undertaken in controlled environments to field agronomic performance is a challenge. The oilseed crop Camelina sativa (camelina), with its innate resilience and plasticity, presents an opportunity to understand both...
