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...

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...

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...

MetabolomicsTranscriptomic and metabolomic changes in postharvest sugarbeet roots reveal widespread metabolic changes in storage and identify genes potentially responsible for respiratory sucrose loss
Endogenous metabolism is primarily responsible for losses in sucrose content and processing quality in postharvest sugarbeet roots. The genes responsible for this metabolism and the transcriptional changes that regulate it, however, are largely unknown. To identify genes and metabolic pathways that ...

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 ...

TranscriptomicsTranscriptome changes in soybean seeds resulting from RNAi suppression of seed storage proteins
We report the changes in transcriptome that results from RNAi suppression of 7S and 11S storage protein synthesis in soybean seeds, Proteomic results show that other proteins compensate for the storage protein shortfall. The transcriptome analysis show numerous changes result from suppressing storag...

MetabolomicsNutritional quality and genetic differences of five amaranth cultivars revealed by metabolome profiling and whole-genome sequencing (Seed assays)

BACKGROUND: Amaranth (Amaranthus spp.) has high nutritional quality, with edible grain and leaves, and many agronomic advantages, making it a promising part of the solution for global food insecurity. However, we lack comprehensive metabolomic and genome sequence data fo...

TranscriptomicsProfiling of transcripts in developing seeds of common bean (Phaseolus vulgaris) lines differing in major storage proteins
To understand the molecular basis for differences of common bean wild-type and mutant in sulphur amino acid content, transcripts were profiled at four developmental stages of seeds from wild-type SARC1 and major seed storage protein-deficient line SMARC1N-PN1 using a CustomArray 90K array. Microarra...

TranscriptomicsDry seed transcriptome differences associated with relief of sly1-2 seed dormancy through after-ripening or overexpression of the gibberellin-receptor GID1b
Plant embryos can survive years in a desiccated, quiescent state within seeds. In many species, seeds are dormant and unable to germinate at maturity. They acquire the capacity to germinate through a period of dry storage called after-ripening (AR), a biological process that occurs at 5-15% moistu...
