Figure. Evolutionary relationships of Acanthobasidium, Aleurodiscus (s.s.) and Neoaleurodiscus
The evolutionary history was inferred by using the Maximum Likelihood method based on the Tamura-Nei model [1]. The tree with the highest log likelihood (-3059.7469) is shown. The percentage of trees in which the associated taxa clustered together is shown next to the branches. Initial tree(s) for the heuristic search were obtained by applying the Neighbor-Joining method to a matrix of pairwise distances estimated using the Maximum Composite Likelihood (MCL) approach. A discrete Gamma distribution was used to model evolutionary rate differences among sites (5 categories (+G, parameter = 0.1542)). The rate variation model allowed for some sites to be evolutionarily invariable ([+I], 54.0453% sites). The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analysis involved 20 nucleotide sequences. There were a total of 935 positions in the final dataset. Evolutionary analyses were conducted in MEGA6 [2].
For all taxa the GenBank number of the DNA-sequence is shown. All black sequences sequences are used bySheng-Hua Wu in his most parsimonious tree, additional sequences are red. [3]
