Comparative Phylogenomics Uncovers the Impact of Symbiotic Associations on Host Genome Evolution
Figure 1
Loss of the arbuscular mycorrhizal (AM) symbiosis in the order Brassicales.
A) For each tested species the symbiotic behavior, host (H) or non-host (NH) is indicated. The probability of having AM symbiosis in ancestral taxa, which were inferred using the maximum likelihood method in Mesquite version 2.75, is indicated for each interior node. Red star indicates the loss of AM symbiosis before the divergence of the Limnanthaceae. B) Moringa oleifera (left) develops a bona fide association with the AM fungus Glomus intraradices whereas Limnanthes douglasii (right) does not.
