Description du projet
Protéger les plantes cultivées et le bétail contre les agents pathogènes
La lutte contre les maladies bactériennes est une priorité absolue pour les agriculteurs qui doivent protéger leurs cultures et leurs élevages contre les agents pathogènes envahissants. C’est l’un des plus grands défis du XXIe siècle. Bien que les plantes aient développé de multiples stratégies de défense pour lutter contre les agents pathogènes envahissants, la résistance aux antibiotiques des bactéries phytopathogènes reste un problème majeur. Le projet T-REX, financé par l’UE, s’appuiera sur des études récentes portant sur le blé, qui ont révélé un mécanisme de reconnaissance inconnu du translocateur effecteur largement conservé dans les bactéries pathogènes. Il visera à caractériser le composant T3SS reconnu, le complexe récepteur membranaire et l’immunité activée. Dans l’ensemble, les résultats mettront en lumière les interactions complexes entre les plantes et les bactéries et pourront éventuellement conduire à l’élaboration de nouvelles stratégies de lutte contre les phytopathogènes.
Objectif
Among the greatest challenges of the 21st century are bacterial diseases that permanently threat plants and animals, including humans to whom they often are lethal. In plant and animal production, bacteria can cause severe yield reductions if not effectively controlled. However, the current control measures include use of environmentally problematic antibiotics, which in addition may lead to appearance of bacterial strains resistant to these antibiotics.
Recent progress in the host laboratory using a Genome Wide Association Study (GWAS) of wheat reveals a hitherto unknown recognition mechanism of the effector translocator widely conserved in pathogenic bacteria. The associated receptor complex is predicted to have wide potential for exploitation in bacterial disease control, not only in crop plants but also in livestock production. In the T-REX project, number of parallel efforts will be taken to characterize the recognized T3SS component, the membrane bound receptor complex and the activated immunity. This will be undertaken using an integrated approach, which involves my background knowledge and experiences combined with the ones of the host institution within molecular genetics, biochemistry, molecular biology and bioinformatics.
This study will shed light on the role of T3SS as a PAMP, which will help us to elucidate the complex plant-bacterial interactions and can potentially lead to the development of new phyto-pathogen control strategies. T3SS being conserved among plant and animal pathogen, the outcome of the T-REX project has potential for extrapolation into animal pathological systems, including humans, and may contribute to the world of medicine.
