Etienne Delannoy – DR INRAe Institute of Plant Sciences Paris-Saclay Combining interactomics and transcriptomics with bioinformatics and statistics, we identified the Arabidopsis coregulation gene network corresponding to the core response to stresses. The chloroplast and its gene expression plays a central role in this core response. We developed specific tools to characterize the function of chloroplast gene expression regulators and especiallypentatricopeptide repeat (PPR) proteins. PPR proteins are involved in all post-transcriptional steps (splicing, editing, processing, translation) of chloroplast gene expression.

Alain Gojon – DR INRAe UMR Biochimie & Physiologie Moléculaire des Plantes – (B&PMP) Biochemistry & Plant Molecular Physiology, Montpellier I am interested in plant nitrogen nutrition; nitrate transport and signalling; adaptive responses of the root system to nitrogen stress and the Impact of climate change on plant mineral nutrition
Xenie Johnson – DR CEA Institut de Biosciences et Biotechnologies Aix-Marseille (BIAM – UMR 7265) CEA Cadarache / Cité des Énergies I am interested in the interactions between the electron transport chain and carbon metabolism; the use of reducing power and the process of light acclimation of photosynthesis via PSII and alternative electron transport pathways.
Anja Krieger-Liszkay – DR CNRS Institute for Cellular Biology (I2BC), department of Biophysics, Biochemistry and Structural Biology, Gif-sur-Yvette
Regulation of photosynthetic electron transport and protection against oxidative stress. I am interested in an integrative approach from the whole leaf to the isolated reaction center. I study the molecular mechanism in vivo using non-invasive biophysical techniques (chlorophyll fluorescence, thermoluminescence, absorption) and in vitro using biophysical and biochemical techniques on isolated membranes/protein complexes. Research mainly on higher plants (Arabidopsis and tobacco), Marchantia polymorpha but also on Chlamydomonas reinhardtii and cyanobacteria.

Norbert Rolland – DR CNRS CD-Adjoint Département BAP INRAe Laboratoire Physiologie Cellulaire & Végétale, Grenoble Decipher the regulatory networks involved in controlling proteome dynamics and chloroplast biogenesis to better understand the adaptation of plants to environmental constraints.
Nicolas Rouhier – Professor, University of Lorraine UMR 1136. Interactions Arbres-Microorganismes I am interested in the regulation of redox metabolism in the chloroplast and more particularly in the maturation of proteins with iron-sulfur centers and the post-translational modifications of cysteinyl residues of proteins.
