Affy_tour_2012-02-Study of sunflower seed dormancy by translatome analysis

ABSTRACT: affy_tour_2012-02 - Identification of transcripts that are addressed to traduction in imbibed seeds in relation with dormancy: comparison of the translatome in Dormant versus Non-Dormant seeds -- 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 2 months at +20°C. Polysomal fractions were purified on sucrose gradients from sunflower axis isolated from dormant and non-dormant seeds imbibed at 10°C during 3h, 15h or 24h. - These fractions allow to identify the transcripts addressed to translation (translatome) during the seed imbibition process (3, 15 and 24h) - The translatome of 2 types of seeds are compared: Dormant vs Non-Dormant at the 3 time points.

transcriptome and translatome of arabidopsis wt seeds according to dormancy-transcriptomic and translatomic analysis of Arabidopsis seeds

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.

Effect of light on translatome of Arabidopsis seeds during 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.

Combined transcriptome and translatome analyses reveal a role for tryptophan dependent auxin biosynthesis in the control of DOG1 dependent seed dormancy

Project description:Transcriptome and translatome analyses of 6 and 24 hours imbibed seeds dormant and non-dormant seeds of NILDOG1-Cvi with and without addition of the transcription inhibitor Cordycepin. NILDOG1-Cvi is the Ler WT containing an introgression of the Cvi accession on chromosome 5, which includes the DOG1 gene (Bentsink et al., 2006).

Gene expression in dormant, germinating and thermoinhibited Arabidopsis seeds

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.

RNA-Seq of seed dormancy in red rice

Project description: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 strong dormancy was used for mRNA expression profiling, by RNA-Seq, of dormant and nondormant dehulled caryopses (here addressed as seeds) at two temperatures (30 °C and 10 °C) and two durations of incubation in water (8 hours and 8 days). Aim of the study was to highlight the differences in the transcriptome of dormant and nondormant imbibed seeds.

affy_sunflower_2010_13-ROS and hormones in sunflower seed dormancy.

Project description:affy_sunflower_2010_13 - affy_sunflower_2010_13 - It concerns the interaction between ROS and hormones in dormancy release in sunflower seeds. ABA is responsible for dormancy maintenance, while GA and ethylene promote seed germination. Based on our results, ROS could represent good candidate to shift from a hormone signalling to another determining the dormancy state in sunflower seeds.-We aim to understand the mechanisms controlling sunflower seed dormancy at the transcriptomic level, by the application of treatments which maintain dormancy as ABA, or alleviate dormancy as ROS and ethylene. Transcripts comparison will be performed between dormant and non-dormant sunflower embryo imbibed 24h on water, on ABA, on methylviologen, a pro-oxidant compound or on ethylene.

Succinylome analyses in the germinating rice seed

Project description:The dehulled rice (Oryza sativa L. japonica. cv. Nipponbare) seeds were washed with distilled water for three times and then imbibed with distilled water in dark growth chamber at 26 °C and 70% relative humidity. About 100 embryos (50 mg) of rice seeds were sliced manually and collected at intervals of 24h after imbibitions (HAI), respectively. After frozen with liquid nitrogen, the samples were stored in −80 °C until used for protein extraction.
