Conservation of symbiotic signaling since the most recent common ancestor of land plants.

ABSTRACT: Plants have colonized lands 450 million years ago. This terrestrialization was facilitated by developmental and functional innovations. Recent evo-devo approaches have demonstrated that one of these innovations was the mutualistic arbuscular mycorrhizal symbiosis (AMS). The genetic pathways that have been involved in the establishment and functioning of AMS since its evolution remain poorly described. Here, we found that intracellular colonization by AM fungi induces a transcriptional reporter of the common symbiosis pathway, well-described in angiosperms, in the liverwort Marchantia paleacea. Mutants of either of the three main genes of this pathway, SYMRK, CCaMK, and CYCLOPS, disrupt the ability of M. paleacea to associate with AM fungi. Finally, overex
