TranscriptomicsA systemic view of coordinated root responses to NO3- heterogeneous environment in Arabidopsis
We investigated the morphological roots decisions of Arabidopsis in a NO3- heterogeneous medium. To do so, we used the Split-Root System which is an experimental set up to assess root decisions in nutrient heterogeneous medium. Split-root plants have been subjected to three different treatments. ‘Co...

TranscriptomicsTranscription profiling of Medicago roots of 6 biological types NO3S, NO3C, NH4S, NH4C, N2S and N2C to investigate Regulation of nitrogen acquisition (NO3-, NH4+ and N2) by nitrogen status
affy_nitrogen_medicago - affy_nitrogen_medicago - Experiment has been designed to characterize the molecular expression patterns associated to a contrasted modification of the nitrogen status of the whole plant. The systemic effects of nitrogen status modifications are investigated and compared on n...

Transcriptomicsaffy_root-dvt-nitrogen_medicago: Genetic determinism of root development in Medicago truncatula
affy_root-dvt-nitrogen_medicago. The biological question is the study of root development adaptation to external nitrogen availability. One of the typical responses to low N provision consists of an increased root branching which promotes soil exploration. In order to differentiate between genes spe...

TranscriptomicsAtNIGT1/HRS1 TARGET approach
This work studies the impact of AtNIGT1/HRS1-GR entrance in the nucleus upond DEX treatment in protoplasts. AtNIGT1/HRS1 TARGET. The whole procedure has been performed as previously described in Bargmann et al Mol Plant 2013. In brief, the protoplasts were transfected with the plasmid pBeaconRFP_GR-...
