Figure 5. Phylogenetic trees of equine DQB.

Figure 5

A. Phylogenetic tree of ELA-DQB genes with codons predicted to contact antigen removed. Trees were created using the neighbor-joining algorithm in MEGA with nucleotide sequences as input. DQB2 (lower branch) and DQB3 (upper branch) are defined clearly in this tree, but DQB1 is not.

B. Phylogenetic tree of 3’UTR sequences for ELA-DQB 1 & 2. DQB1 clusters into a unique locus with high confidence in this tree (upper branch). 3’UTR sequence for the DQB3 gene was not available for analysis.
