Welcome, Pierre Gautrat!
Pierre Gautrat, a new CNRS researcher at IPS2, is studying how legume development is regulated in response to nitrogen.
Pierre Gautrat has been recruited as a CNRS researcher at the Institute of Plant-Sciences Paris-Saclay - IPS2 (CNRS/INRAE/UEVE/UPSaclay, Gif-sur-Yvette) the 1st of October 2026, within the SILAB team (Signaling pathways regulating Legume root system Architecture through Beneficial bacteria).
He specializes in systemic (long-distance) signaling pathways regulating nitrogen nutrition and legume symbiotic nodulation, as well as their integration with other environmental cues to coordinate plant development and adaptation.
After obtaining a Master’s degree in Plant Biology from Paris-Cité University, he carried out his PhD (2017–2020) at IPS2, where he extensively characterized the systemic regulation of nitrogen-fixing nodulation in legumes. His work identified root-shoot-root communication circuits that fine-tune symbiotic nodulation according to the plant’s nitrogen requirements. He was then awarded an EMBO postdoctoral fellowship to join Ronald Pierik’s laboratory at Utrecht University in the Netherlands. During this postdoc (2021–2024), Pierre investigated the integration of nitrogen and light signaling in Arabidopsis, uncovering new systemic signaling mechanisms triggered by nitrogen availability that modulate shade-avoidance responses. Back at IPS2 (2024–2026), he pursued a second postdoc investigating signaling peptides that modulate root vascular development to accommodate symbiotic nodulation.
Pierre was then recruited as a CNRS researcher at IPS2 within the SILAB team. He is establishing his own research program focused on the systemic regulation of legume shoot development in response to different sources of nitrogen, whether mineral or symbiotic. His research notably aims to identify mobile molecular signals originating from the roots and decipher the mechanisms by which these signals are integrated to enable shoot adaptation to different nitrogen regimes.
