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...

TranscriptomicsIdentification of putative H2O2 regulated genes during the establishment of the Sinorhizobi...
The involvement of ROS in the legume – Rhizobium symbiotic interaction has been highlighted (Santos et al., 2001; Rubio et al., 2004). This interaction is characterized by the formation of a new organ on the root, the nodule and by the penetration, in parallel, of the bacteria into the root tissue v...

TranscriptomicsIdentification of ABA regulated genes in sunflower
Abiotic stress and more specifically drought is the major limiting factor for sunflower production. ABA is a key hormone for drought stress response in plants and sunflower. This experiment aims at identifying ABA responsive pathways in order to better understand sunflower responses to drought. We s...

Transcriptomicsxyleme-Molecular bases of acclimation and adaptation to water deficit in poplar.
affy_popsec_orleans_poplar - xyleme - This project aims to identify candidate genes for water deficit acclimation and/or adaptation in a tree species: poplar. Due to compelling evidence that transcriptional regulation plays a major role in regulating many biological processes, we will look for genes...

TranscriptomicsIdentification of genes involved in the establishment of plant-microorganism interactions
affy_pathogen_medicago - In compatible interaction between plants and biotrophic microorganisms, neoformation of organs occurs to ensure an efficient relationship between both partners. During the interaction between Medicago truncatula and Sinorhizobium meliloti, bacteria induce the development of ...

Transcriptomicsaffy_dormance_totalrna_sunflower-Molecular mechanisms of seed dormancy release: transcriptome evolution and ROS signalling during sunflower seed after-ripening.
affy_dormance_sunflower - affy_dormance_totalrna_sunflower - We focus our research on the release of embryonic dormancy in sunflower seeds and more precisely on the molecular mechanisms controlling seed dormancy release during dry after-ripening. Our data show an increase of ROS during dormancy rele...
