      Non-coding RNAs in environmental adaptation

      The non-coding transcriptome of two Arabidopsis ecotypes suggests new mechanisms for plant adaptation to soil environment
      Protein-coding genes are largely conserved among organisms. This conservation is...

      The same transcription factor regulates two antagonistic signaling pathways

      The NIN transcription factor coordinates CEP and CLE signaling peptides that regulate nodulation antagonistically 
      Legume plants tightly regulate symbiotic nitrogen-fixing root nodule number to balance...



    • Role of WIP transcription factors in male flower formation


      An integrative genome-wide analysis reveals role of WIP transcription factors in male flower formation
      Flowers are the reproductive organs of angiosperms. The production of unisexual flowers and plants...



    • A new step towards understanding cytokinin action in symbiotic nodulation

      The plant hormone cytokinins regulate many developmental processes and environmental responses, including symbiotic nitrogen-fixing nodulation in legume plants. Cytokinin signalling activation recruits...

      New roles for an atypical MAPK module

      Mitogen Activated Protein Kinase (MAPK) modules are important plant signaling components involved in developmental processes as well as in responses to environment stresses. They are usually composed...



    • 13 PhD subjects for scholarships at IPS2!

      Each year the French government offers several hundreds of scholarships to pay the salaries of PhD students during years. These scholarships are attributed through a concourse organized by the Doctoral...



    • Not so (immuno)depressed these nodules!

      Some plants, including legume plants, are able to host mutualistic bacterial partners in symbiotic root nodules. This interaction gives rise to exchanges: the bacteria supply nitrogen to the plants, which...

      At the crossroads of systemic pathways regulating symbiotic nodulation

      The Compact Root Architecture 2 (CRA2) pathway promotes root competence for nodulation through the miR2111 systemic effector
      Nitrogen-deprived legume plants form new root organs, the nodules, following...



    • Systemic regulation of lateral root angle

      Systemic regulation of lateral root angle and root system architecture
      The CEP signaling peptide pathway controls from shoots the angle of lateral root formation and thus root system architecture
      Lateral...



    • Redox regulation of plant HDACs in response to climate change

      Kick-off REPHARE project : Redox regulation of plant HDACs in response to climate change
      Histone deacetylases (HDACs) are key epigenetic regulators but how their activity is regulated remains largely unknown...

      How the genome “dark matter” regulate distant genes ?

      A long non-coding RNA affects 3D chromatin conformation of distant loci through DNA-RNA hybrids or R-loops 
      In the last years, a large portion of the eukaryotic transcriptome which does not code for any...

      4 PhD Thesis recently defended at IPS2

      Xiaoyun CUI
      Dynamics of histone modification in integration of metabolic activity and stress response
      Chromatin enzymes require important metabolites as substrates or cofactors. However, little is known...



    • EPITRANS PLATEFORM: the haute-couture workshop for the genetic improvement of crops in the service of tomorrow's varietal models.

      This month, the Life Sciences Department of Paris-Saclay University highlights the Epigenetic and Translational Research Platform of the Institute of Plant Sciences Paris-Saclay (IPS2) in a FOCUS PLATFORM...
