RESEARCH SUBJECTS

Fabrice Roux obtained his Ph.D. degree in 2004 on the management of herbicide resistance using Arabidopsis thaliana as an experimental model (under the supervision of Xavier Reboud, laboratory of Biology and Management of Weeds, INRAE Dijon). After his Ph.D., he spent one year as a junior lecturer in the laboratory of Genetics and Evolution of Plant Populations (GEPP, University of Lille 1) and worked on the evolution of early-flowering in plants. He then spent a too short period (only one year) in the laboratory of Joy Bergelson (University of Chicago), where he became interested in identifying the genetic basis of quantitative resistance in the pathosystem A. thaliana-Pseudomonas viridiflava. Recruited as a CNRS researcher in 2006 at the GEPP (University of Lille 1), he developed his own research theme on ecological genomics of adaptation in A. thaliana. In 2012, he then co-led the research theme 'Global change: from ecological genomics to community ecology’. The research of Fabrice mainly focused on (i) the identification of the genetic basis of complex adaptive traits with the desire to replace A. thaliana in an ecologically realistic context, and (ii) the study of adaptation at different spatial and temporal scales. Since July 2013, Fabrice joined the LIPME after obtaining a junior starting grant from the Labex TULIP (Toulouse). His current projects focus on ecological genomics of organism – organism interactions. He is particularly interested in identifying the genetic basis underlying coevolution in plant-microbiota-pathobiota pathogen and plant-plant interacting systems. Since 2021, he co-leds the team with Fabienne Vailleau.

RESEARCH SUBJECTS

Fabienne Vailleau obtained her Ph.D. degree in 2003 at the University of Toulouse, Ph.D. realized at the LIPM in Dominique Roby’s group, on the Arabidopsis thaliana/Xanthomonas campestris pv. campestris pathosystem. After her Ph.D. she was Assistant Professor at the INP-ENSAT, where she set up the Medicago truncatula/Ralstonia solanacearum pathosystem.  She was then recruited in Michel Petitprez’s group at the INP-ENSAT with a position of Associate Professor, where she continued her research on plant-bacteria interactions, giving lectures at the same time at INP-ENSAT in Plant Pathology and Weeds Science. From 2008 to 2015, she was the head of the 3rd year of specialization “Plant Agrobiosciences’. In 2008, Fabienne joined LIPM to perform her research in the group of Stéphane Genin and Christian Boucher. She worked on the post translational mechanisms required for the pathogenicity of the bacterium R. solanacearum. She obtained her Habilitation in 2016, and reoriented her projects on searching for plant proteins targeted and manipulated by R. solanacearum effectors, especially with approaches using association genetics. In 2020, she joined the team of Fabrice Roux to continue and integrate her work into a more global research theme in order to characterize and understand the molecular dialogue between the plant and its associated microbial cortege. In this context, she is currently developing a theme in the ECOGEN team on plant-microbiota-pathobiota interactions. Since 2021, she co-leds the team with Fabrice Roux.

Dominique ROBY, Research Director CNRS

Dominique did her PhD in the Laboratory of Plant Physiology in Toulouse; her work concerned the study of defense mechanisms triggered by fungal elicitors in plants and the signalling role of ethylene. She was then recruited in 1982 as a CNRS researcher to work on the regulation of chitinase genes in plants upon fungal infection. After 4 years, she moved to Rutgers University (USA) and then to the Department of Agricultural Products of E. DuPont de Nemours (USA) where she investigated the role and transcriptional regulation of chitinase genes during plant immune responses. Then she joined the LIPM in 1990 and started a group in collaboration with Yves Marco, working on plant-bacteria interactions, and more particularly on plant genes involved in the control of the Hypersensitive Response, a form of programmed cell death for which there was still very limited information. The main goals of her research are now to identify  key components of quantitative disease resistance (QDR) in Arabidopsis to an agronomically important pathogen: Xanthomonas campestris, and to understand the role of some QDR components on the plant microbiota. In parallel, she is exploring the genetic and molecular bases of competitive plant-plant interactions. These projects, first developed in tight collaboration with Fabrice Roux, are now run in the ECOGEN team. 

Dominique has been director of the LIPM from 2011 to 2015, coordinator of the LabEx TULIP from 2011 until 2019 (https://www.labex-tulip.fr/Le-LabEx) and is currently Deputy Head of INRA Division - Plant Health & Environment  (http://www.spe.inra.fr/) since 2013.

RESEARCH SUBJECTS

During my 1st postdoc in Olivier Loudet's team at INRA Versailles, I used quantitative genetics combined with high throughput phenotyping to identify the genetic and molecular bases of vegetative growth in A. thaliana. The use of natural variation in these experiments led me to work on the ecological reasons of plant adaptation and in evolutionary biology. I did a 2nd postdoc in Cris Kuhlemeier's team at the University of Bern, where I studied the influence of pollinators on speciation in the Petunia genus, combining quantitative genetics, functional genomics and molecular biology.

I joined the ECOGEN team as a researcher since October 2019, to work on the molecular mechanisms involved in natural variation of the response to other plant species in A. thaliana. This is a fascinating subject because despite the importance of the interactions between plants in shaping plant communities, we know very little about the mechanisms of adaptation and co-evolution between them. In addition, a better understanding of these interactions may be useful for the agroecological transition.

For her PhD, she moved to the MPIPZ in Cologne, Germany, and worked in the groups of Paul Schulze-Lefert and Stéphane Hacquard. There, she studied the multikingdom microbial communities associated with roots of natural Arabidopsis thaliana populations across Europe and the impact of microbial interactions on plant health. She was then then granted a Postdoctoral Fellowship with CEPLAS and moved to the group of Ruben Garrido Oter, also at the MPIPZ. There, she studied the microbiota composition and interactions at the phycosphere of the model microalgae Chlamydomonas reinhardtii, and investigated the microbial composition overlap with land plants. She is now part of the ECOGEN lab, where she will study the pathobiota of A. thaliana natural populations, investigating the host and microbial genetic factors, as well as environmental cues, that underlie these interactions.

I'm currently studying for a Master 2 in Plant Biology, with a specialization in "Plant-Microbe Interaction for Plant Health" at Claude Bernard Lyon 1 University. I obtained my Bachelor's degree in Life Sciences, with a specialization in "Biodiversity Sciences" at the same university in 2022. In 2023, I carried out my Master 1 internship on plant-beneficial bacteria interactions, studying the response of five natural accessions of Arabidopsis thaliana to single inoculations or co-inoculations of pairs of 4 OTUS (Operational Taxonomic Unit) bacterial commensals of the phyllosphere, as part of the ECOGEN team with Rémi DUFLOS, Fabienne VAILLEAU and Fabrice ROUX. I am now doing my Master 2 internship in the same team on the identification and functional validation of bacterial genes involved in growth promotion in Arabidopsis thaliana.
