At IPS2, we want to better understand the molecular and genetic mechanisms controlling plant growth and their regulation by endogenous and exogenous signals of biotic and abiotic origins.

Analysis of these mechanisms is conducted in an integrated manner at cellular, organ and whole plant levels.

IPS2 applies multidisciplinary approaches (combining genomics, molecular and cellular biology, bioinformatics, biochemistry, genetics, physiology) and also develop tools (including bioinformatics and modelling) required to provide more predictive knowledge and facilitate "translational" research between model species and crops.


The unit has two platforms encompassing different facilities dedicated to plants :

  • EPITRANS: regrouping facilities in Translational Biology  (managing large TILLING collections in tomato, Brachypodium, melon and cucumber) and Epigenomics (genome-wide analyses such as ChIPseq, HiC and others)
  • SPOMICS: regrouping facilities in Transcriptome and RNA sequencing involving also related methodologies, Interactomics (protein-protein interactions) and Metabolomics with the recent aim of developing fluxomics.


The IPS2 emerges from an important restructuration and consolidation
of 3 of the 4 Plant Biology Institutes involved in the Cluster of Excellence
or LabEx SPS "Saclay Plant Sciences".

We expect that IPS2 teams interact in innovative projects with industrial partners and/or technical institutes and contribute to the future of agriculture.
