Microbial recruitment mechanisms in complex interactions of plant roots, mycorrhizal fungi and soil microbes

The root-associated microbiome is a key determinant of soil nutrient availability, plant biomass productivity and pollutant degradation, but could not be examined in depth prior to recent advances in high-throughput sequencing and bioinformatics. Plant root-associated microbiome refers here to the whole community of bacteria and fungi living on the surface and/or inside plant roots. Arbuscular mycorrhizal fungi (AMF) constitute a widespread soil fungal group that establishes symbiotic associations with the majority of vascular plants. Once AMF colonize plant roots, they develop an extraradical hyphal network, promote nutrient uptake, in particular phosphorus and nitrogen, and protect plants against soil-borne pathogens. As fungi that extend their hypha into the rhizosphere and the surrounding soil, AMF not only interact with plants, but also with a myriad of soil microbes. Several
