Loss of arbuscular mycorrhizal (AM)‐conserved genes in the order Proteales.

Homologs of common symbiotic pathway (CSP) genes are present in both host (H) and non‐host species. In contrast, homologs of ‘AM‐conserved’ genes were lost in known non‐hosts (Lupinus albus and Arabidopsis thaliana) as well as in the Proteales species indicated here. Boxes indicate presence, with gray indicating presence based on previous studies. Lines indicate absence. Genes indicated by a transparent red box are considered ‘conserved’ genes based on available literature (Delaux et al., 2014).
