BRIO's missions

  • Analysis of diversity and adaptation of cereal-associated bacteria.
  • Decipher the physiological and molecular responses of cereals towards root-associated bacteria and more generally to their root microbiome.
  • Elucidate links between the plant microbiome and plant resistance to diverse pathogens (including phytoparasitic nematodes, bacterial & fungal pathogens).
  • Train students from North and developing countries to our topics of interest (licence, master, PhD, postdoc).

Main objectives

  • Identify adaptative frontiers between phytobeneficial and phytopathogenic burkholderias in rice, as well as between root-associated Paraburkholderia and Burkholderia strains (bacterial genes involved in the interaction with the plant, and the plat host response).
  • Isolate and characterize the diversity of plant microbiomes in contrasted agricultural practices of rice (traditional, agroecology, organic) in West Africa (Burkina-Faso, Senegal) and South East Asia (Cambodia).
  • Develop biocontrol solutions against rice phytopathogens, based on plant microbiome-knowledge (secondary metabolites, bioinoculants, synthetic microbiomes).
  • Research areas : Interactions plant-microorganisms, Microbiology, Microbial Ecology, Population genetics, Parasitology, Biochemistry of secondary metabolites.
