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...

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 ...

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...

TranscriptomicsTranscription profiling of Arabidopsis seed germination in presence and absence of histone deaceatylase inhibitor, Trichostain A (TSA).
Histone acetylation is involved in the regulation of gene expression in plants and eukaryotes. Histone deacetylases (HDACs) are enzymes that catalyze the removal of acetyl groups from histones, which is associated with the repression of gene expression. To study the role of histone acetylation in ...

TranscriptomicsTranscriptome changes associated with relief of sly1-2 seed dormancy through after-ripening or overexpression of the gibberellin-receptor GID1b
Seed dormancy is the inability for seeds to germinate even under favorable conditions. In the Arabidopsis Landsberg erecta (Ler) ecotype, 2 weeks of dry storage, called after-ripening, is sufficient to relieve seed dormancy. Such seed is referred to as after-ripened (AR) and has a hi...

TranscriptomicsFlux of transcript patterns during soybean seed development
Background: To understand gene expression networks leading to functional properties of the soybean seed, we have undertaken a detailed examination of soybean seed development during the stages of major accumulation of oils, proteins, and starches, as well as the desiccating and mature stages, using ...

TranscriptomicsKarrikin responses in Arabidopsis thaliana seed
Karrikins promote seed germination in Arabidopsis thaliana. Completion of germination (protrusion of the radicle) is not observed until ~72 h in dormant wildtype seed under these conditions. We used microarrays to examine karrikin-induced transcriptional changes after 24 h of imbibition. Transcripti...
