The symbiosis between land plants and arbuscular mycorrhizal fungi (AMF)
is one of the most widespread and ancient mutualisms on the planet.
However, relatively little is known about the evolution of these symbiotic
plant-fungal interactions in natural communities. In this study, we
investigated the symbiotic AMF communities of populations of the native
plant species Pilea pumila (Urticaceae) with varying histories of
coexistence with an non-mycorrhizal invasive species, Alliaria petiolata
(Brassicaceae), known to affect mycorrhizal communities. We found that
native populations of P. pumila with a long history of coexistence with
the invasive species developed more diverse symbiotic AMF communities.
This effect was strongest when A. petiolata plants were actively growing
with the natives, and in soils with the longest history of A. petiolata
growth. These results suggest that despite the ancient and widespread
nature of the plant-AMF symbiosis, the plant traits responsible for
symbiotic preferences can nevertheless evolve rapidly in response to
environmental changes.
