Phosphorus nutrition and root-associated fungal microbiota of nonmycorrhizal Arabis alpina

Associations with mycorrhizal fungi greatly enhance phosphorus (P) uptake for most plants, but the Brassicaceae are nonmycorrhizal due to the loss of essential symbiosis genes. Almario et al. investigated the fungal microbiota of Arabis alpina, a Brassicaceae species that grows in very-low P soils. The…
