Plants take up the nitrogen necessary for their growth mainly in the form of nitrate. To cope with spatio-temporal fluctuations in NO3- availability in soils, these organisms have developed adaptation mechanisms specific to each situation. Plant N response involves several signaling pathways that depend on the N variation scenarios of the medium. Two major signaling pathways are studied in this thesis. The Primary Nitrate Response (or PNR) which corresponds to the rapid (within minutes) and nitrate-specific responses of the plant when provided with Nitrate. The Nitrogen Starvation response (or NSR) which corresponds to the slower response (within days) which makes it possible to overcome the lack of N in the medium. Although some molecular ...
