RESEARCH SUBJECTS
During my career, I have studied the mechanisms and regulation of virulence in several models of host-pathogen interactions (plant and animal pathogens).
Today, my project focuses on the study of genetic determinants of adaptation and pathogenesis of plant pathogens during infection, exploiting the new perspectives offered by recent "Omics" technologies. The project focuses on the Brassica black rot disease caused by the vascular pathogen Xanthomonas campestris pv. campestris (Xcc).

RESEARCH SUBJECTS
Most Xanthomonas bacteria translocate Transcription Activator-Like Effector (TALE) proteins inside plant cells using their type III secretion machinery. TALEs are a unique type of bacterial effector proteins that help the pathogen to exploit and modify the plant environment by directly and specifically inducing the expression of plant genes to the benefit of bacteria. TALE-mediated induction of a subset of genes, referred to as susceptibility genes, can promote host colonization and disease. Those genes could represent new sources of black rot resistance by loss of susceptibility. My project aims at studying the mechanisms by which TALEs mediate susceptibility to Xanthomonas in Brassicaceae.

RESEARCH SUBJECTS
Hydathodes are openings on the leaf margin of most plants that release water during the process known as guttation. My current interest is to decipher the role of hydathodes especially in plant immunity combining transcriptomic, functional genomic and physiology.
Superficially hydathodes do look like stomata and until recently have lied very much in the shadow of their more high-profile, gas-exchange-controlling neighbours (Perrin, 1970). However, hydathodes host many biological functions that are also important for the whole plant (Cerutti et al., 2017, 2019). When the stomata are close, during the night for instance, excess water is discharged by this organ and is often mistaken with dew.
Hydathode are a potential infection routes of a growing number of harmful microbes, including one that cause black rot on brassicaceae such as Arabidopsis and cauliflower, Xanthomonas campestris pv. Campestris.
TRAINING
After a PhD in Plant Biology earned in Grenoble in 1991, I have worked on the model plant Arabidopsis using a combination of functional genomic, metabolomics and quantitative genetic approaches. I joined the group of J. Browse at Washington State University in 1994 to study for four years the role of plant polyunsaturated fatty acid for cold and heat stress tolerance. I went then to the group of C. Benning at IGF-Berlin for one year and continued this work from 1998 to 2001 in the team of L. Lepiniec at INRA Versailles where he was among the first to clone the DAGAT gene whose product catalyses the last step in oil synthesis (and fat). I was hired at INRA in 2003 as a full-time research engineer in the group of L. Lepiniec. I developed there several projects dealing with flavonoid synthesis in Arabidopsis seed especially on the chemical identification of these still poorly studied metabolites and on the genetic bases of their variability. From 2012 to 2018, I moved to Toulouse and another model plant tomato to focus on the molecular mechanism leading to the development of fruit flesh at the Genomic and Biology of Fruit laboratory.

RESEARCH SUBJECTS
Xanthomonas bacteria are able to translocate TALE (Transcription Activator-Like Effector) proteins into plant cells to activate transcription of plant susceptibility (S) genes and promote disease. This is the case of Xanthomonas campestris pv. campestris (Xcc), the causal agent of black knot disease of Brassicas.
My PhD project aims to identify and characterize the S genes targeted by Xcc TALEs in cauliflower and Arabidopsis, with a particular focus on the SWEET (Sugar Will Eventually be Exported Transporter) gene families. The ultimate goal of this project is to generate new sources of resistance by loss of sensitivity in Brassicaceae

Plants set up complex immune responses capable of controlling the multiplication of most of the microbes they encounter. Although it is well described that humidity is one of the factors favoring the spread of plant diseases, the underlying molecular mechanisms are hypothetical. My thesis project aims to determine to what extent the control of apoplastic water flows is an integral part of Arabidopsis immunity and to identify the genetic determinants of Xanthomonas allowing this pathogenic bacterium to manipulate water flows during the infection.
