The Laboratoire de Biophysique Moléculaire aux Interfaces (LBMI) is part of the “Chimie des agrobiosystèmes” axis in the AGROBIOCHEM Department of Gembloux Agro-Bio Tech and of the biophysics platform. The unit is a research laboratory devoted to molecular biophysics and computer assisted modelling. Our research activities are mainly focused on the study of the interaction between biomolecules (from proteins to small organic molecules) with the membrane by complementary biophysical tools to understand their structure/activity relationships.

The membrane is a barrier that allows exchange with the environment and also prevents pathogens to penetrate cells. Lipids and membrane proteins are notably able to induce signals that enhance cellular responses after a pathogen attack. Plants have also very efficient immune system and it was recently shown that one plant membrane protein called REMORIN (REM) is implied in the fight against viruses by preventing their propagation. To understand how this protein is anchored to the membrane and how its membrane localisation is involved in the antiviral response, a collaboration between five french teams and our lab has demonstrated the importance of the segregation of REM into functional lipid domains. By our multidisplinary approach bridging biophysics, biochemistry, structural and plant biology, we have shown that REM is bound to specific lipids from the inner leaflet of the plasma membrane (called phosphoinositides) by an unconventional anchor that induces the formation of REM-enriched lipid domains. The dynamic and aggregating properties of those domains are crucial for inducing antiviral responses. This study opens the way for understanding at a molecular level how plants respond to pathogen attacks and what is the role of the plasma membrane in those molecular processes.
