A postdoctoral position is available to join a research group studying the association of plants and

arbuscular mycorrhiza (AM) fungi. AM fungi are mutualistic endosymbionts of plants; their hyphae

inhabit the root cortex and the soil, and within these widely differing environments they interact with

complex microbial communities. Pofiling studies revealed that microbial communities tightly associated

with extraradical hyphal surfaces are conserved (at higher taxonomic rank) across fungal species and

soils (1). This project will investigate the influence of plant species and genotype on community

composition, use high-resolution spatial mapping to map the spatial structure of hyphal microbe

communities, and analyze community functions.
