Overexpression of MtABI3 in transgenic Medicago truncatula roots

ABSTRACT: ABI3 is a B3-domain transcription factor that acts as a master regulator 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 ABI3 gene of Medicago. Using the Medicago NimbleGen chip, a transciptomic analysis was performed to identify differentially expressed genes compared to the GUS expressed control.

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 ABI3 gene of Medicago. Using the Medicago NimbleGen chip, a transciptomic analysis was performed to identify differentially expressed genes compared to the GUS expressed control. Two-condition experiment, GUS versus genomic. Biological replicates: 3 control (35S::GUS), 3 treatment (35S::Genomic ABI3 sequence), independently grown and harvested. One replicate per array.

Overexpression of MtABI3 splicing forms by ectopically expressing cDNA sequences in transgenic Medicago truncatula hairy roots generated from an abi3 mutant background (mutant NF6003)

Project description:ABI3 is a B3-domain transcription factor that acts as a master regulator of seed maturation. To identify genes that are regulated specifically by different splicing forms in the model legume Medicago truncatula, Medicago hairy roots obtained from an abi3 mutant background (NF6003) were generated using Agrobacterium rhizogenes transformed with the three cDNA sequence of the ABI3 gene splicing forms of Medicago. Using the Medicago NimbleGen chip, a transcriptomic analysis was performed to identify differentially expressed genes compared to the GUS expressed control.

Overexpression of MtHSFA9 in hairy roots of Medicago truncatula

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

Comparison of genes differentially expressed between Medicago R108 and abi3 mutants (NF3185 and NF6003) during different stages of seed development (16, 24, 32 and 40 DAP)

Project description:ABI3 is a B3-domain transcription factor that acts as a master regulator of seed maturation. To identify genes that are regulated specifically by ABI3 in the model legume Medicago R108 during seed development, using the Medicago NimbleGen chip, a transcriptomic analysis was performed between abi3 mutants (NF3185 and NF6003) and R108 wild-type at 4 stages of seed development.

RNA-Seq analysis of Medicago truncatula hairy root lines treated with methyl jasmonate

Project description:In hairy roots of the model legume Medicago truncatula the saponin production can be elicited by methyl jasmonate treatment. To identify genes potentially involved in saponin biosynthesis or its regulation we carried out transcript profiling by RNA-Seq of M. truncatula hairy roots treated with 100 μM of methyl jasmonate (dissolved in ethanol) for two or 24 hours. As control, M. truncatula hairy roots treated with an equivalent amount of ethanol were profiled.

Medicago truncatula seed development under greenhouse conditions

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.

Medicago truncatula seed development at 21-19°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 21-19°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.

Medicago truncatula drought stress recovery

Project description:Molecular Elasticity and Adjustment of Drought Recovery Dynamics of 14N- and 15N-fertilized Legume Medicago truncatula. Climate change in conjunction with population growth necessitates a systems biology approach to characterize plant drought response and a more thorough understanding of the underlying molecular mechanisms. During drought stress and recovery, the metabolome and proteome regulate and are regulated through diverse mechanisms including synthesis and degradation. In order to study this complex regulation network, a front-end multilevel analysis is presented for the first time, investigating protein turnover, regulatory classes of proteins and metabolites as well as post translational ubiquitination of a target set of proteins during a severe stress and recovery scenario in the model legume Medicago truncatula. Evidence for enhanced translational proteome regulation was observed during drought recovery and functional clusters of differentially dynamic phases during the course of recovery were defined. The data give novel insights into molecular elasticity that enable recovery of drought stressed plants. Additionally, these results offer putative targets and metabolic pathways for future plant-bioengineering towards enhanced drought stress tolerance.
