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 ...

MetabolomicsThe diversity of quinoa morphological traits and seed metabolic composition

Quinoa (Chenopodium quinoa Willd.) is an herbaceous annual crop of the amaranth family (Amaranthaceae). It is increasingly cultivated for its nutritious grains, which are rich in protein and essential amino acids, lipids, and minerals. Quinoa exhibits a high tolerance towards various abi...

MetabolomicsHow Does the Seed Pre-germinative Metabolism Fight against Imbibition Damage? Emerging Roles of Fatty Acid Cohort and Antioxidant Defence

During seed imbibition, lipids are engaged in membrane reorganization while facing free radical-mediated oxidative injury. In the present work, we explored changes in lipid components at different timepoints of imbibition (0.5, 2, 4, 6, and 8 h) in the legume Medicago truncatula, by combining bio...

MetabolomicsUltrasound Priming Enhances Seed Vigor and Multiple Stresses Tolerance in Aged Maize Seeds

Seed aging leads to reduced germination rates and vigor, particularly under stress conditions. We subjected aged maize seeds to 40 seconds of ultrasonic treatment, which enhanced their vigor and tolerance to combined stress. The ultrasonic treatment increased more cracks and holes in the seed coa...

MetabolomicsSeed Metabolome Analysis of a Transgenic Rice Line Expressing Cholera Toxin B-subunit
Rice (Oryza sativa L.) is a candidate crop for production of plant-based vaccines by genetic engineering technologies. MucoRice-CTB has been developed as a rice-seed-based vaccine against cholera by transgenic expression of modified cholera toxin B-subunit (CTB) under the RNA interference (RNAi)-med...

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. ...

MetabolomicsCharacterization of the heat-stable proteome during seed germination in Arabidopsis with special focus on LEA proteins
During seed germination, desiccation tolerance is lost in the radicle with progressing radicle protrusion and seedling establishment. This process is accompanied by comprehensive changes of the metabolome and proteome. Germination of Arabidopsis seeds was investigated over 72 h with special focus on...

MetabolomicsUltrasound Priming Enhances Seed Vigor and Multiple Stresses Tolerance in Aged Maize Seeds
Seed vigor plays a crucial role in germination rate, population uniformity, seedling stress resistance and potential yield at maturity. Here we report a simple, eco-friendly physical method (40-second ultrasound) that rapidly triggers aged seeds to enhance seed vigor and stress resistance. Significa...

MetabolomicsAnalysis of seed germination attributes and kinetics of Polygonatum sibiricum Red. through metabolomics and transcriptomics

Polygonatum sibiricum Red. (P. sibiricum) seeds exhibit strong dormancy, which prolongs germination period, reduces germination rate, and thus hinders its production. Research on breaking seed dormancy via optimized sand storage and clarifying germination-related mechanisms is insufficient. This ...

MetabolomicsIntegrated lipidomic and transcriptomic analysis uncovers the lipid dynamic changes in Camellia weiningensis during seed development

Oil-tea Camellia is a promising woody oil crop that has been widely used as a cooking oil, lubricant, and cosmetics. However, there is a lack of dominant varieties suitable for high-altitude cold mountainous regions. Camellia weiningensis (C. weiningensis) is the only h...
