Figure 2

Neighbor-joining phylogenetic tree of 57 PabHLH members with 59 Drosophila melanogaster bHLH members. The NJ tree summarizes the evolutionary relationship between the PabHLHs and DmbHLHs, which has been rooted using OsRa (a rice bHLH motif sequence of R family) as outgroup. This tree is based on a multiple alignment that includes 59 bHLH sequences of D. melanogaster and 57 PabHLH members. For simplicity, branch lengths of the tree are not proportional to distances between sequences. Only bootstrap values more than 50 are shown. The higher-order group labels are in accordance with Ledent et al. (2002).
