Résumé

Understanding mechanisms that underlie high nutrient (phosphate, nitrogen) use efficiency by mycorrhizal plants, and carbon allocation in a context of multitrophic interactions between biotrophic organisms (symbiotic, pathogenic, neutral), is critical for sound management of both crop lands and forests. Indeed, availability, uptake and exchange of nutrients in biotrophic interactions will govern plant growth and modulate biomass allocation, both of which are central to plant yield, a major outcome in the context of high biomass production. Uptake and exchanges of nutrients and/or metabolites at biotrophic interfaces are controlled by membrane transporters, of which the regulation patterns are essential in determining the outcome (beneficial, antagonistic) of plant-fungal interactions and in adapting to changes in soil nutrient quantity and/or quality. The identification and functional analysis of fungal transporters in mycorrhizal systems will provide key information about those central to uptake by soil-growing hyphae, those responsible for efficient nutrient and/or metabolite export and import at the plant- fungus interface in the symbiosis, and those involved in successful nutrient competition with other soil micro-organisms. The presentation will focus on the current state of the art and highlight powerful tools for the identification and characterization of new fungal transporters driving biotrophy in arbuscular mycorrhiza.
