Figure 6. Phylogenetic analysis of V_L segments in coelacanth.

The relationships of V_L genes were inferred using the Neighbor-Joining method. All positions containing gaps and missing data were eliminated; % bootstrap replicates are given on the tree. A total of 66 positions of framework region were represented in the final dataset. The Lc sequences are denoted by ‘JHxxxxxx’, followed by their positions on the scaffolds. Sequence identification numbers (GI) of all other taxa are mentioned after the species name. The light chain classes are given to the right of the tree and are in complete accordance with branching topology. The Sigma-2 designation is the former Sigma-cart subclass that had previously been found only in cartilaginous fishes.
