Aboveground herbivory suppresses the arbuscular mycorrhizal symbiosis, reducing plant phosphorus uptake

Most terrestrial plants form associations with arbuscular mycorrhizal (AM) fungi, which are soil-dwelling microbial symbionts that provide plants with soil nutrients, while plants supply the fungi with carbon. The majority of these plants are also subject to herbivory from insects, thus tripartite interactions between insect herbivores, plants, and AM fungi are ubiquitous. This study assessed how aboveground herbivory from a generalist insect...
