Laboratory of Plant-Microbe Interactions

Members - Arbuscular Mycorrhizal Symbiosis Efficacy

Benoit Lefebvre, DR2 INRA

During my PhD (1999-2004) at Louvain-la-Neuve (Belgium) under the supervision of Professor Marc Boutry, I worked on the characterization and trafficking to the plasma membrane of H+-ATPases, proteins generating the electrochemical gradient across the plasma membrane. I joined the LIPM for a post-doc (2004-2007) in Julie Cullimore’s team and I was recruited in 2007 as an INRA research scientist. Between 2004 and 2011, I worked on the characterization of LysM Receptor-Like Kinases from the legume Medicago truncatula that are essential for nodulation. In 2011, I was on sabbatical and I worked in the laboratory of Professor Pamela Ronald at Davis (CA, USA) on another plant receptor kinase, XA21 involved in Oryza sativa (rice) immunity. From 2012, I searched for LysM Receptor-Like Kinases in non-legumes involved in the perception of arbuscular mycorrhizal fungi and establishment of the symbiosis with these fungi. Since 2016, I have developed a new line of research on the efficacy of this symbiosis to promote plant growth and resistance to stress.

Recruited at INRA Toulouse in the UMR181 INRA / ENVT in 2001, I joined the UMR1318 at INRA Versailles in 2003 to work on the mechanisms of post-transcriptional regulation of gene expression in Arabidospsis thaliana. I then participated in the study of the biosynthesis of cellulose during the cellular elongation process of the same model plant. I joined the group of Clare and Julie in 2011. I am involved in the biochemical studies on the perception of the microbial symbiotic signals by Medicago truncatula. I contribute to the synthesis/purification/quantification of ligands needed for the characterization of the receptor/ligand interaction experiments and the work on endogenous binding proteins or putative Nod factor receptors expressed in various systems (eucaryotes or procaryotes).

I have graduated from Southwest University in China with a master degree in Agriculture Science. I granted a scholarship from Wuxi Shuguang Agriculture Science and Technology Development company, so I could do my PhD studies in Toulouse University. I am supervised by Benoit Lefebvre and my PhD project is about the "Role of fungal symbiotic signals and their plant receptors in the arbuscular mycorrhizal symbiosis in Solanaceae plants".

Recently graduated with a master degree of Vegetal Biology at the University Paul Sabatier of Toulouse, I acquired fundamental knowledge in vegetal sciences and in ecology. Thanks to two internships in laboratories, field of interactions between plants and microorganisms, microbiology and genetic have aroused my interest. I am currently a PhD student supervised by Benoit Lefebvre of the team “Symbiotic signaling” at the LIPM and Christophe Roux of the team “Endomycorrhizal symbiosis and cell signaling” at the LRSV. Our study deals with the effects of agronomic practices on the microbiota of wheat roots and the symbiotic efficiency of arbuscular mycorrhizal fungi.
