The mutualistic arbuscular mycorrhizal (AM) symbiosis arose in land plants more than 450 million years ago and is still widely found all major plant lineages. Despite its broad taxonomic distribution, little known about the molecular components underpinning outside of flowering plants. ARBUSCULAR RECEPTOR-LIKE KINASE (ARK) required for sustaining AM distantly related angiosperms. Here, we demonstrate that ARK has an equivalent role maintenance bryophyte
