Figure. Evolutionary relationships of Boidinia and Gloeopeniophorella
The evolutionary history was inferred using the Minimum Evolution method [1]. The optimal tree with the sum of branch length = 0.44296624 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches [2]. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the Kimura 2-parameter method [3] and are in the units of the number of base substitutions per site. The ME tree was searched using the Close-Neighbor-Interchange (CNI) algorithm [4] at a search level of 2. The Neighbor-joining algorithm [5] was used to generate the initial tree. The analysis involved 17 nucleotide sequences. All positions with less than 95% site coverage were eliminated. That is, fewer than 5% alignment gaps, missing data, and ambiguous bases were allowed at any position. There were a total of 1188 positions in the final dataset. Evolutionary analyses were conducted in MEGA6 [6]
