Impacts of long-term elevated atmospheric CO₂ concentrations on communities of arbuscular mycorrhizal fungi.

ABSTRACT: The ecological impacts of long-term elevated atmospheric CO₂ (eCO₂ ) levels on soil microbiota remain largely unknown. This is particularly true for the arbuscular mycorrhizal (AM) fungi, which form mutualistic associations with over two-thirds of terrestrial plant species and are entirely dependent on their plant hosts for carbon. Here, we use high-resolution amplicon sequencing (Illumina, HiSeq) to quantify the response of AM fungal communities to the longest running (>15 years) free-air carbon dioxide enrichment (FACE) experiment in the Northern Hemisphere (GiFACE); providing the first evaluation of these responses from old-growth (>100 years) semi-natural grasslands subjected to a 20% increase in atmospheric CO₂ . eCO₂ significantly increased
