RESEARCH SUBJECTS

Since 1985 when I started my PhD in Mike Daniel’s group at the John Innes Institute (UK), I have been studying how plants and bacteria interact together. Firstly, I worked in plant pathology with two phytopathogenic bacteria, Xanthomonas campestris and Ralstonia solanacearum, and their host plants. I studied the molecular mechanisms both by which these bacteria infect and cause disease symptoms on plants, and those that enable plants to resist such infection. During my analysis of the hrp genes of R. solanacearum as a post-doc in Christian Boucher’s group at the LIPM, I contributed to the discovery that the type III secretion system is conserved with bacterial mammalian pathogens, and is involved in secreting elicitors for disease and the hypersensitive reaction in plants. I was recruited by the CNRS in 1998 in Jean Dénarié’s group at the LIPM. Since then I have been studying the molecular and genetic mechanisms of early symbiotic signalling between Medicago truncatula and the two endosymbiotic microorganisms of this plant, Sinorhizobium meliloti and arbuscular mycorrhizal fungi. I was involved in the identification of a Nod factor signalling pathway in M. truncatula, and the demonstration that this is common between the two symbioses. I am particularly interested in the roles of LysM receptor proteins in plant-microbe interactions, as well as the interconnections between biotic and abiotic signalling mechanisms, including the role of redox signalling.

RESEARCH SUBJECTS

I was trained as a geneticist and developmental biologist. After a PhD on seed development in Arabidopsis (Gif-sur-Yvette, France), a first post doc on modelling of leaf development (JIC, Norwich, UK) and a second one on symbiotic signalling during nodulation in Medicago truncatula (LIPM, Toulouse), I was hired at CNRS to lead a project on how symbiotic microbial signals stimulate root development. To do so, I use approaches such as transcriptomics, natural variation (quantitative genetics) and reverse genetics. My research interests encompass :

  • Root phenotyping (medium and high-throughput)

  • Crosstalks between symbiotic and hormonal signalling

  • Root development in Medicago truncatula

  • Crosstalks between root cell layers (such as epidermis and cortex).

TRAINING AND RESEARCH SUBJECTS

I graduated from Angers engineering school, with the option “Research Master 2 in plant biology”. During these studies, I did my traineer periods at INRA (in Avignon) and IRSTEA (in Rennes). Later, in 2019, I followed a professional license in plant Biotechnologies at Paul Sabatier (Toulouse), to improve my technical skills in laboratory. During this licence, I realized my traineer period in the SMS team. As I was very interested by the Medicago-Sinorhizobium symbiosis, I am happy to continue to work on this thematic for some month.

TRAINING AND RESEARCH SUBJECTS

I'm graduated with an ecology degree and a plant biology master from the University Paul Sabatier of Toulouse (France) in 2020. I arrived in the SMS group thanks to an internship in which I characterized a biosensor of the reactive oxygen species (ROS)  in planta. I also made phylogenetics studies on genes capable of synthetizing those molécules (the RBOH gene family).

Since 2021 I'm a PhD student in the SMS team. My project is funded by the Duality ANR project which aims to decipher the molecular mechanisms involved in immunity and legume symbiosis in the legume clade of plants. My purpose is to study specificaly the interactors of the NFP gene during biotic interactions thanks to genetics, transcriptomics and microscopy studies.

RESEARCH SUBJECTS

After a career in the UK, I was recruited by INRA in1991 to direct a new team to work on the perception and response of the legume plant to symbiotic signals.

In 2018, I relinquished the direction of the team to other members, and currently I am continuing my research on Nod factor perception by «lysin-motif receptor-like kinases» (LysM-RLK), using molecular biology, biochemical and genetic approaches.

RESEARCH SUBJECTS

During my PhD (2010-2013), I characterised the function and regulation of a family of proteins, the ferritins controlling iron homeostasis in plants and root architecture. After my PhD, I wanted to keep working on plant nutrition, by studying how root development controls nutrient acquisition. For this, I joined the group of Prof. David E. Salt working on the formation of root barriers and how they contribute to the acquisition of mineral nutrients, water from the soil and microbiome assembly. I was recruited by the CNRS in 2021 to characterise the role of endodermal barriers during plant-microbe interactions. I am particularly interested in the roles of the endodermis in gating nutrient exchanges between the vascular tissues and endosymbiotics structures formed by rhizobium and arbuscular mycorrhizal fungi.
