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 ...

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...

TranscriptomicsPenfield: Understanding the affect of maternal environment on seed dormancy
Maternal environment is an important regultor of seed dormancy, but the mechanisms underlying the process are poorly understood. We have found that genes in the circadian clock control dormancy, in part through their regulation of the canonical photoperiod pathway known from research into flowering ...

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...

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 ...

TranscriptomicsDormancy of green-cotyledon Col seeds matured at 20°C vs 15°C
To determine genes involved in induction of dormancy in response to reduced maturation temperatures, RNA sequencing was performed on developing seeds matured at 20°C, where low dormancy is observed, and compared to seeds matured at 15°C where high dormancy is observed. Col green cotyledon seeds matu...

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 Arabdiopsis wild type and G'4-3 seeds grown with different nitrate concentrations to investigate effects on seed dormancy
Freshly harvested Arabidopsis seeds (ecotype Col0 obtained under 10 mM nitrate nutrition, referred to as C10 seeds) are dormant and do not germinate when sown on an agarose-based medium. However, when C10 seeds are sown on 10mM nitrate or when Col0 mother plants are grown on 50 mM nitrate (referred...

TranscriptomicsGriffiths et al. AMP1 is involved in development of seed dormancy in arabidopsis
Total RNA was extracted from arabidopsis thaliana (Columbia) seeds 10 days after pollination from 2 sets of 3 biological replicates of wild-type and mutant plants. Mutant plants were AMP1-1 mutants carrying a stop codon in the middle of the gene resulting in truncated protein.

TranscriptomicsRNA-Seq of seed dormancy in red rice
Red rice fully dormant seeds do not germinate even under favourable germination conditions. In several species, including rice, seed dormancy can be removed by dry-afterripening (warm storage); thus, dormant and nondormant seeds can be compared for the same genotype. A weedy (red) rice genotype with...
