Mechanisms of beneficial legume-microbe interactions

subject

description

Understanding mechanisms underlying high nutrients use efficiency and carbon allocation in a context of legumes-microbe interactions at the root level (mycorrhiza and nodules) is critical for sound management of croplands taking care of ecosystem services rendered by beneficial microbes. Indeed, availability, uptake and exchange of nutrients in biotrophic interactions will drive plant growth and modulate biomass allocation, that are central to plant yield, a major outcome, in the context of high biomass production. Transport processes across the polarised membrane interfaces are of major importance in the functioning of the established symbiosis as the relation is based on a 'fair-trade' between microbes and host plant. Uptake and exchanges of nutrient and/or metabolites, at biotrophic interfaces are controlled by membrane transporters and their regulation patterns are essential in determining the outcome of plant microbe interactions and in adapting to changes in soil nutrient quantity and/or quality. In the present talk, the current status regarding transport systems as well as future challenges will be highlighted.
