Bayesian analysis of Exechonella vieirai and Parantropora penelope intron sequences constructed using MrBayes v.3.2.6; 5,000,000 generations; 2,500,000 generations burn-in. Introns EV-H-nad5 and EV-nad5 had been concatenated. Ambiguously aligned positions had been excluded using Gblocks v.91b. Posterior probabilities and maximum likelihood bootstrap values (1000 replicates) as estimated using RAxML v.8.2.12 are given at the nodes. Analyses were carried out under the HKY + G model of nucleotide evolution. Reverse transcriptase and intron maturase open reading frames had been removed from EV-cox1 and PP-cox1-i introns. Intron names correspond to those shown in Fig. 2. Branch length scale bar indicates number of substitutions per site.
