Project description:Transcriptome analysis of wild type and sweet1 seeds upon treatments during germination
| PRJNA684572 | ENA
Project description:Purpose: The goals of this study are to compare the transcriptome profiling between wild type and sweet1 under the treatments of either the glucose, ABA or both during germination. Methods: After 3-day imbibition, sweet1 seeds were sown on ½ MS medium and grown under constant light, 22 °C for 24 hours. Seeds were transferred to ½ MS liquid medium supplemented with either 60 mM Glc, 5 µM ABA or both for 6 hours. Four biological replicates were collected for each treatment. Total RNA was extracted by RNeasy PowerPlant Kit (13500-50, Qiagen), The libraries were prepared from 1 µg total RNA using KAPA mRNA Hyper Prep kit (KK8581, Roche) with KAPA Dual-indexed Adapter kit (KK8722, Roche). The libraries were sequenced by Hiseq 2500 (Illumina) with paired-end reads. Results: Gene expression level was quantified using Kallisto v 0.44.0 by mapping to Arabidopsis thaliana (version 11) primary transcript sequences. Samples were evaluated based on pair-wise comparison between different conditions and outliers within each treatment were removed for the further analysis based on PCA results. Candidates with more than 10 counts per million reads in at least 50% samples, |b| ≥ 0.2 and q-value < 0.05 were identified as differentially expressed genes (DEGs) using Sleuth program. Hierarchical clustering of DEGs uncovered several pathways that may contribute to glucose antagonizing ABA function. Conclusions: This study represents the detailed analysis of transcriptome in germinating seeds under ABA+Glc treatment. Our study provides a new perspective on the interaction between ABA and Glc in response to external stimuli to control the seed germination.

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:Transcriptomic study of the impact of osmopriming on rape seeds (Brassica napus L.; cv 'Libomir') during priming process and after germination. The assays were replicated twice on two independent priming and germination experiments. Seeds were osmoprimed in PEG solution (-1.2 MPa osmotic potential) during 7 days, dried to initial moisture content and then germinated for 7 hours on water. The analysis during different phases of priming procedure (soaking and drying), after whole osmopriming process and germination were done.

Project description:Transcriptome changes were investigated for Euphorbia esula (leafy spurge) seeds with a focus on the effect of constant and diurnal fluctuating temperature on dormancy and germination. Leafy spurge seeds do not germinate when incubated for 21 days at 20°C constant temperatures, but nearly 30% germinate after 21 days under fluctuating temperatures 20:30°C (16:8 h). Incubation at 20°C for 21 followed by 20:30°C resulted in approximately 63% germination in about 10 days. A cDNA microarray representing approximately 22,000 unique sequences was used to profile transcriptome changes.

Project description:Seeds are highly resilient to the external environment, which allow plants to persist in unpredictable and unfavorable conditions. Some plant species have adopted a bet-hedging strategy to germinate a variable fraction of seeds in any given condition, and this could be explained by population-based threshold models. Here, in the model plant Arabidopsis (Arabidopsis thaliana) we induced secondary dormancy to address the transcriptional heterogeneity among seeds that leads to binary germination/non-germination outcomes. We developed a single seed RNA-seq strategy that allowed us to observe a reduction in seed transcriptional heterogeneity as seeds enter stress conditions, followed by an increase during recovery. We identified groups of genes whose expression showed a specific pattern through a time course and used these groups to position the individual seeds along the transcriptional gradient of germination competence. In agreement, transcriptomes of dormancy-deficient seeds (mutant of DELAY OF GERMINATION 1 gene) showed a shift towards higher values of the germination competence index. Interestingly, a significant fraction of genes with variable expression encoded translation-related factors. In summary, interrogating hundreds of single seed transcriptomes during secondary dormancy-inducing treatment revealed variability among the transcriptomes that could result from the distribution of population-based sensitivity thresholds. Our results also showed that single seed RNA-seq is the method of choice for analyzing seed bet-hedging-related phenomena.

Project description:An experiment was performed to compare global transcription patterns in two tissues of Lepidium sativum seeds at different times during imbibition leading up to, but not including, radicle protrusion from the seed (e.g. germination). RNA extractions from the two tissues were hybridised to CATMA Arabidopsis microarrays. The two tissues were the radicle and the micropylar endosperm cap that covers it. The interaction of these two tissues is thought to control the timing of germination though alterations in the extensibility of the radicle and the physical resistance of the micropylar endosperm cap to radicle penetration.

Project description:To establish the basis for understanding molecular mechanism of seed germination response to temperature, we analyzed transcriptomes in freshly harvested dormant and dry stored after-ripened seeds. The after-ripened seeds started to show visible germination from 36h after the start of imbibition, and almost all the seeds germinated after 3 days. The freshly harvested seeds stayed dormant by imbibition at 26°C, and germination of the after-ripened seeds was almost completely inhibited at 34°C. Total RNA was prepared from 0 (dry), 6 and 24h imbibed seeds to find regulatory genes of seed dormancy and germination.
