Laboratory of Microbial Ecology of the Rhizosphere and Extreme Environments (LEMIRE)

The research goals of the LEMIRE are :
- to understand how the rhizosphere functions by characterizing the carbon fluxes and molecules exuded by plants and the structuring effect they have on soil bacteria populations. The Pseudomonas brassicacearum-Arabidopsis thaliana model is used to decode the molecular dialog between plants and bacteria and to determine the effects of their association on plant physiology and health and vice versa.
- to characterize tolerance mechanisms to ionising radiation and desiccation in Deinococcus deserti.
- to study the Ramlibacter tataouinensis cell cycle and its tolerance to desiccation.
