Figure 2. Bayesian consensus phylogenetic tree in the Musae clade of the C. gloeosporioides species complex, constructed with concatenated sequences of the ITS region, ACT, CHS, GAPDH, and ApMat with the best evolutionary model applied for each gene. Posterior probabilities ≥0.90 and bootstrap support ≥50% are shown in the nodes (BI/ML). Scale bar: substitutions per site.
