Plant interaction traits determine the biomass of arbuscular mycorrhizal fungi and bacteria in soil.

ABSTRACT: Plant-arbuscular mycorrhizal fungal (AMF) mutualisms are crucial to ecosystem biodiversity and productivity. Yet, our understanding of the functional roles of plants as AMF generalists or specialists, and the consequences of these plant interaction traits for soil ecosystems are virtually unknown. We grew eight pasture plant species under two experimental conditions, sequencing their root AMF communities to assess interaction traits using a range of numeric and phylogenetic diversity metrics, thereby characterizing each plant species' interaction generalism with AMF. We used lipid analysis of rhizosphere soils and Bayesian modeling to explore how host interaction traits affected carbon allocation to AMF and bacteria. We found that plant interaction traits for AMF remained stable despite la
