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.
