Niche theory, the description of an organism’s environmental requirements for survival and reproduction, has been a central tenet of ecology for decades (Hutchinson, 1957). While plant (Enquist et al., 2016) and animal (Moran-Ordonez et al., 2017) niches have been extensively studied, characterization of microbial niches has lagged behind that of larger flora and fauna. Despite advances in defining niches of harmful microorganisms, such as human pathogens (eg Coccidioides immitis, causative agent of Valley Fever; Gorriset al., 2019) and poisonous mushrooms (eg Amanita phalloides; Wolfe et al., 2010), the biogeography and environmental drivers influencing many microorganisms are still hidden. In this issue of New Phytologist, the groundbreaking work by Davison et al.(2021; pp. 763–776) sheds light on organismal niches for a whole functional guild of microorganisms, arbuscular mycorrhizal (AM) fungi, for the first time.‘... the groundbreaking work by Davison et al.(2021) sheds light on organismal niches for a whole functional guild of microorganisms, arbuscular mycorrhizal (AM) fungi, for the first time.’AM fungi are geographically widespread (Kivlin, 2020) and associate with up to 72% of plant species (Soudzilovskaia et al., 2020), forming a foundational symbiosis where plants provide fungi with carbon in exchange for mineralized soil nutrients (Parniske, 2008). As such, AM fungi can substantially alter plant community composition, enhance agricultural yields, and impact ecosystem biogeochemical cycles (van der Heijden et al., 1998). Given their societal and ecological importance, some initial investigations probed single niche axes of AM fungi (eg plant hosts; Davison et al., 2020) or the niche of a single AM fungal species (Kivlin et al., 2017). Yet, despite their pivotal role in ecosystems, a comprehensive, guild-level understanding of AM fungal niches has been lacking.
