Phylogenetic trees resulting from phylogenomic analysis and molecular dating. A. Consensus topology and branch lengths from analyses of concatenated amino acid sequences from 35 single copy genes with a total of 10129 data columns. Gapped and poorly aligned sites were removed. Analyses were performed with the CAT-GTR model. Posterior probabilities are shown at the nodes of the tree. Scale bar indicates expected changes per site. B. Chronogram resulting from a lognormal relaxed molecular clock analysis with the birth-death prior. The mean divergence time with standard error are shown at each node. Circled nodes were pre-calibrated before the analysis. The paleontological periods, in million years ago (Mya), are shown as a scale at the bottom. Rhizophagus irregularis (Glomeromycota) was used as the outgroup.
