CPJ/SPMIR : Interactions dynamiques entre plante-microbes et environnement

Bacterial phytopathology is not limited to bilateral interactions between a pathogen and its host, but results from complex processes that also involve plant-beneficial microorganisms.  

Plant Growth-Promoting Rhizobacteria (PGPR), such as certain strains of the genus Bacillus, play a protective role by inhibiting colonization by pathogens and/or by strengthening plant defenses. 

However, mechanistic knowledge regarding plant protection by PGPR remains limited.

We study the interactions between phytopathogenic bacterial strains of the genus Xanthomonas, PGPR strains of the genus Bacillus, and host plants, in order to decipher the inter- and intra-organismic mechanisms that promote either plant infection or resistance particularly under environmental stress conditions by examining the impact of climatic factors on the dynamics of these interactions.

The studies are conducted using an integrative and holistic approach, based on advanced techniques such as biophysical tools like next-generation biosensors,microfluidics, high-resolution fluorescence imaging, as well as omics analyses. 

The objective is to understand the mechanisms of interaction with fine spatiotemporal resolution under conditions that simulate natural environments in a highly controlled manner.
