Biotrophic interactions resulting from an intimate contact between plant and microbial structures drive either bidirectional flows of nutrients as symbiotic (mycorrhizal or legume-rhizobia) or unidirectional flows as in pathogenic interactions. Whatever the biotrophic context (symbiotic versus pathogenic), nutrients as well as signalling molecules must pass several membrane barriers and the apoplastic interface before their assimilation by plant or microbial cells. Plant and microbial cells must be ‘re-programmed’, which includes differentiation and polarisation of membrane transport functions to take, to transfer or to exchange signalling molecules and nutrients between partners of the biotrophic interaction. Membrane transporters are thus key players in nutrient uptake and exchange mechanisms and their regulation patterns are essential in determining the outcome of plant fungal interactions and in adapting to environmental changes.

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. In a long term approach unravelling those biotrophic transportomes and their underlying mechanism will be extremely useful in the development and implementation of environmentally sound crop production systems.

This Research Topic of Frontiers focuses on the fascinating question of how signals and nutrients are transferred between partners in symbiotic association or in pathogenic interaction. Reviews and original articles that we plan to host in this Topic will illuminate molecular pathways of the symbiotic or pathogenic microbes and the host involved in transport of solutes across different cellular barriers as well as provide insights into fundamentals of plant-microbe interactions.


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
