Popis: SPEINRAUBIPM DOCT; Plants can influence microorganism population through exudation of sugars notably as carbon source. Indeed, the type of plant-microorganism interaction (PMI) is linked to the trophic exchanges between plant and microorganism. Microorganisms are thus able to “manipulate” the host to modify sugar fluxes. In mycorrhizal symbiosis, the plant has a supply of nutrients by the fungal partner, which in return receives sugars. In pathogenic relationship, the microorganism will divert sugars provided by the plant without compensation. Despite identification of sugar transporters at biotrophic interfaces, molecular and cellular mechanisms by which microorganisms operate the distribution of sugars are poorly understood. Our aim is to characterize plant membrane dynamics related to sugar transport in PMI. The project is conducted on various tobacco cell suspensions. First, we analyzed cell responses to different microbial molecule treatments (mycorrhizal factors and elicitor). Secondly, we measured uptake of sugars in cells upon microbial molecules. Then, we followed expression of genes encoding sugar transporters in response to microbial molecules using screening gene and protein databases of tobacco sugar transporters.
