Nutrient exchange within common mycorrhizal networks is altered in a multispecies environment

Popis výsledku v původním jazyce

Although it is known that arbuscular common mycorrhizal networks (CMNs) mediate below-ground interactions between one or two species, little is understood about their role in mediating interactions among multiple, co-occurring plant species. 2. We investigated the CMN-mediated interactions among two Central European species, Inula conyzae and Crepis biennis within pots and the impact of a third plant, an invasive Echinops sphaerocephalus, on these relationships. We examined changes in C-to-P exchange within a CMN formed by Funneliformis mosseae sourced from Central Europe by tracking plant C cost with C-13 signatures of 16:1 omega 5 and P acquisition to hosts with P-33 only accessible to CMNs. 3. When only native plants were present, the C cost was consistent for both species, despite CMNs favouring C. biennis with P uptake. In the presence of E. sphaerocephalus, CMNs also favoured C. biennis with P, but while C. biennis and E. sphaerocephalus provisioned similarly large portions of C-13, I. conyzae provided less. Mycorrhizal P acquisition, therefore, was the costliest for E. sphaerocephalus, which likely mitigated some I. conyzae&apos;s C cost even though both received a low proportion of P-33 from CMNs. 4. Echinops sphaerocephalus altered mineral nutrient and C exchange proportions between native plants and their CMN, suggesting that this species alters below-ground plant interactions and that not only specific characteristic of plant host and fungal partner but also the wider plant community mediates resource exchanges between CMNs and individual plants.
