High CO 2 promotes fatty acid-dependent asymbiotic growth of Rhizophagus clarus

Year: 2026

Type: preprint

Abstract: Arbuscular mycorrhizal (AM) fungi form symbioses with most terrestrial plants and play an ecologically important role in soil carbon dynamics. However, direct CO 2 effects on the fungi remain unclear. We show that CO 2 -enriched conditions enhance the asymbiotic growth of Rhizophagus clarus in the presence of fatty acids. The response pattern to high CO 2 differed between the tested species. These findings provide new insights into the physiological characteristics of AM fungi.
