Figure 2

Minimum evolution tree showing the phylogenetic relationship of TCR Vα/δ gene segments from avian species compared to mammals and to an amphibian. Main groups are encased by triangles and species in each group are indicated. Bootstrap values based on 1000 replicates are shown in parenthesis for each group. Avian groups are color coded as in figure 1. Nucleotide sequences of the V regions were aligned using ClustalX (Thompson et al. 1997) and BioEdit (Hall 1999) programs. Phylogenetic analyses were performed using MEGA version 4.1. (Kumar et al. 2004). GenBank numbers for sequences used in this analysis are provided in supplementary table 1.
