FIGURE 4.

Phylogenetic analysis of BmYellow-e. A, phylogenetic tree constructed from 22 Yellow proteins of D. melanogaster (Dm) and B. mori (Bm). B, phylogenetic analysis of BmYellow-e and Yellow-e proteins from other insects. Amino acid sequences were aligned using the ClustalX program, and the phylogenetic tree was constructed by the neighbor-joining method. Bootstrap values after 1000 replications are shown. GenBank^TM accession numbers and abbreviation of each protein are given in Table 2. Boxes indicate the bts gene (BmYellow-e).
