Phylogenetic analyses of TRMV to other V genes from TCR and Ig loci. A: The relationship of the V gene segments from IgH, IgL, NAR, TRA, TRD, TRB, TRD and TRM. Tree shown was generated using the neighbor joining method. Opossum TRM sequences are indicated in bold. Numbers at the nodes indicate the percent bootstrap values based on 1000 replicates. B: Phylogenetic tree showing the relationship of V gene segments from opossum TRM to IgH V gene segments from four distantly related marsupials. This analysis includes all the opossum IgH V genes which belong to three different subgroups (VH1–VH3). Available VH1 sequences from the brush-tail possum, tammar wallaby, Northern brown bandicoot and Virginia opossum were also used in the analysis. NAR-TCR was used as an outgroup. The tree was generated using the neighbor joining method with the Tajima-Nei model. Bootstrap values are indicated as in figure 9A.
