Project description:au14-10_wd40 - effet of light on translatome of arabidopsis seeds during germination - Does light regulates germination via polysome association ? - At harvest seeds are dormant.They stay dormant if stored at -20°C.A.Th dormant seeds dont germinate at 25°C in darkness.Total RNA and polysomal RNA (polysomal fractions purified on sucrose gradients)were extracted from imbibed seeds for 20h at 22°C in darkness and light(3 biological replicates). Transcriptome and translatome are compared for light vs dark for 20h of imbibition. In silico comparison will allow to compare transcriptome and translatome for each type of sample.

Project description:The goal of this study was to compare the transcriptional profile (RNA-seq) of imbibed Arabidopsis thaliana Columbia-0 ecotype seeds that were treated with a 20 min red or far red pulse. The red-light pulse induces germination.

Project description:In depth temporal profiling of transcript changes at 10 time points during germination in Arabidopsis seed was carried out. The time course utilised, encompassed seed maturation, stratification, germination and post-germination and provided a global investigation into the tightly regulated, phasic changes that define seed germination. A previously unidentified transient expression pattern was identified for a group of genes, whereby a significant rise in abundance was observed at the end of stratification and significantly lower expression observed up to 6 hours later. Total RNA extraction was carried out on 80 mg of Arabidopsis seeds at 10 time points during germination in triplicate. The time points selected were: freshly harvested seed (H), seeds following 15 days of ripening (0 h), seeds after; 1 h of stratification (1 h S), 12 h of stratification (12 h S), 48 h of stratification (48 h S), followed by seed collected 1 hour into the light (1 h SL), 6 hours into the light (6 h SL), 12 hours into the light (12 h SL), 24 hours into the light (24 h SL) and 48 hours into the light (48 h SL).

Project description:au13-12_polysome - transcriptome and translatome of arabidopsis wt seeds according to dormancy - Identification of transcripts that are differentially abundant (transcriptome) and transcripts that are addressed to translation (translatome) in imbibed Arabidopsis seeds in relation with dormancy. During imbibition of seeds (16h and 24h in darkness at 25°C, dormant and non-dormant seeds), transcriptome analysis is done on total RNA and translatome analysis on polysomal RNA. - At harvest seeds are dormant. They stay dormant if they are stored at -20°C (D) and become non-dormant (ND) if they are stored 3 weeks at +20°C. Arabidopsis dormant seeds do not germinate at 25°C in darkness while non-dormant seeds do. Total RNA and polysomal RNA (polysomal fractions purified on sucrose gradients) were extracted from imbibed seeds for 16h or 24h at 25°C in darkness (3 biological replicates). Transcriptome and translatome are compared for Dormant vs Non-Dormant for 16h and 24 imbibition. In silico comparison will allow to compare transcriptome and translatome for each point and type of seeds and to compare the time points (16 vs 24h) for each type of sample.

Project description:This series analyses germinating Arabidopsis seeds with both temporal and spatial detail, revealing two transcriptional phases that are separated with respect to testa rupture. Performed as part of the ERA-NET Plant Genomics grant vSEED. Arabidopsis seeds were dissected into four tissues at nine time-points during seed germination. The tissues were the combined micropylar and chalazal endosperm (MCE), the remaining endosperm (PE), the radicle and embryonic axis (RAD) and the cotyledons (COT). At testa and endosperm rupture the seeds were sampled in separate pre- and post-ruptured populations.

Project description:Mature seeds of Arabidopsis thaliana are desiccation tolerant, but they lose DT while progressing to germination. Yet, there is a small developmental window during which DT can be rescued by treatment with polyethylene glycol (PEG). We used microarrays to identify relevant genes in the re-establishment of desiccation tolerance by PEG.
