Project description:We analysed transcriptome changes between seed devlopement (4 stages corresponding at before (S1) and after (S2) desiccation tolerance acquisition and before (S3) and after (S4) longevity acquisition) in dissected seed tissues (embryo, E; Endosperm Eo and Seed Coat SC)
Project description:We analysed the methylated cytocines in gDNA sequence of Medicago (A17) embryos during seed maturation concerning Heat Stress. Embryos were harvested at four developemental stages (called S1 to S4): 17, 26, 36 and 44 days after polination (DAP) at 20°C and 14, 17, 22 and 28 days after polination (DAP) at 26°C.
Project description:Transcriptional profiling of seeds of Medicago truncatula during maturation. To identify genes that are regulated during seed maturation in the model legume Medicago truncatula, plants at flowering stage were grown at variable light and temperature conditions under greenhouse environment (period March-June). Seeds were then collected at different stages of development. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed to follow the differential expression of genes during seed maturation.

Seeds were then collected at different stages of development. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed to follow the differential expression of genes during seed maturation. Seeds of Medicago truncatula were collected at different developmental stages, 9 developmental stages were analysed. Two replicates from each developmental stage were used for dye switch, each time the control was considered as the earlier developmental stage vs the treatment corresponding to the later developmental stage. For each repetition 5 hybridisation were made: 16DAP vs 20DAP, 24DAP vs 28DAP, 32DAP vs 36DAP, 40DAP vs Abs, DS (Rep1 and Rep2) vs 16DAP (Rep3 and Rep4). For each biological replicates, RNA was extracted from 50 seeds collected from 5 different plants, grown in the same conditions. One replicate per array.
Project description:Transcriptional profiling of seeds of Medicago truncatula during maturation. To identify genes that are regulated during seed maturation in the model legume Medicago truncatula, plants at flowering stage were grown at controlled temperature of 21-19°C, 16h light. Seeds were then collected at different stages of development. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed to follow the differential expression of genes during seed maturation.
Project description:Transcriptional profiling of seeds of Medicago truncatula during maturation. To identify genes that are regulated during seed maturation in the model legume Medicago truncatula, plants at flowering stage were grown at controlled temperature of 20/18°C 16 h light/dark, in osmotic stress conditions (-0.1 Mpa). Seeds were then collected at different stages of development. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed to follow the differential expression of genes during seed maturation.
Project description:Transcriptional profiling of seeds of Medicago truncatula during maturation. To identify genes that are regulated during seed maturation in the model legume Medicago truncatula, plants at flowering stage were grown at controlled temperature of 14/11°C, 16h light/dark. Seeds were then collected at different stages of development. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed to follow the differential expression of genes during seed maturation.
Project description:A transcriptome analysis of developing abi5 and wild type (R108) seeds from Medicago truncatula was performed to decipher the role of ABI54 in the regulation of late seed maturation and seed longevity.
Project description:HSFA9 (Medtr4g126070) is a seed-specific heat shock transcription factor that is upregulated during the later stages of seed maturation. To identify genes that are regulated by this transcription factor in the model legume Medicago truncatula, Medicago hairy roots were generated using Agrobacterium rhizogenes transformed with the genomic sequence of the genomic HSFA9 gene of Medicago. Using the Medicago NimbleGen chip, a transciptomic analysis was performed to identify differentially expressed genes compared to the GUS expressed control
