Medicago truncatula seed development at under greenhouse conditions

ABSTRACT: 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 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.

Medicago truncatula seed development at 21-19Â°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 controlled temperature of 21-19Â°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. Seeds of Medicago truncatula grown at 21-19Â°C were collected at different developmental stages, 15 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 8 hybridisation were made: 8DAP vs 11DAP, 14DAP vs 17DAP, 20DAP vs 23DAP, 26DAP vs 29DAP,32DAP vs 35DAP, 38DAP vs 41DAP, 44DAP vs Abs, DS (Rep1 and Rep2) vs 8DAP (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.

Medicago truncatula seed development at 14/11Â°C 16 light/dark

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 14/11Â°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. Seeds of Medicago truncatula grown at 14/11Â°C, 16h light/dark were collected at different developmental stages, 10 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: 22DAP vs 28DAP, 34DAP vs 40DAP, 46DAP vs 52DAP, 58DAP vs 65DAP,Abs vs DS. 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 20/18Â°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. Seeds of Medicago truncatula grown at 20/18Â°C 16 h light/dark in osmotic stress conditions of -0.1 Mpa, were collected at different developmental stages, 7 developmental stages were analysed.

Transcription profiling of Medicago truncatula radicles incubated in polyethylene glycol solution and embryos at different time points after pollination to study dessication tolerance

Project description:Time course of the transcriptome of desiccation-sensitive 2.7-2.9 mm-long radicles of Medicago truncatula seeds at different time points during incubation in a polyethylene glycol (PEG) solution at -1.7 MPa and 10°C, resulting in a gradual re-establishment of desiccation tolerance. Gene profiling was also performed on embryos before (14 days after pollination) and after acquisition of desiccation tolerance during maturation (20 days after pollination).

Transmission of xanthomonads to Medicago truncatula seeds

Project description:Plant pathogenic bacteria disseminate and survive through transmission to and by seeds of hosts and non-hosts plants. To investigate the interaction between xanthomonads and developing seeds of Medicago truncatula, plants at the M-oM-,M-^Bower bud stage were spray inoculated until runoff with xanthomonads suspensions. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed on seeds to characterize the molecular dialogue between Xanthomonas campestris pv. campestris in an incompatible situation with M. truncatula seeds and Xanthomonas alfalfae pv. alfalfae in a compatible situation at two developmental time points (16 and 32 days atfter pollination (DAP). Six-condition experiment, 16dap_Mock versus 16dap_Xaa, 16dap_Mock versus 16dap_Xcc, 32dap_Mock versus 32dap_Xaa, 32dap_Mock versus 32dap_Xcc. Biological replicates: 6 controls (16dap_Mock, 32dap_Mock), 12 treatments (16dap_Xaa, 16dap_Xcc, 32dap_Xaa, 32dap_Xcc), independently grown and harvested. One replicate per array.
