FIGURE 3.

ML tree based on the KS domain of KAF0502938.1, a hybrid NRPS-PKS of G. margarita. The sequence of G. margarita, as well as that of its endobacterium, CaGg, are highlighted. The sequences of G. margarita and G. rosea are gathered into a bacterial clade which is well separated from the Dikarya group. The sequence of the CaGg endobacterium clusters into a sub-clade which is well separated from the Gigaspora sequences, but which contains sequences from Myxococcus. Despite its homology with the Gigaspora sequences, the PKS from the basal fungus P. finnis seems to have a fungal signature. Bootstrap support values are shown on the tree nodes. Thick lines indicate Bayesian posterior probability ≥95%.
