Phylogenetic tree of the silkworm ABC transporters. The phylogenetic tree was constructed using a neighbor-joining technique to analyze the amino acid sequences of the nucleotide binding domain (NBD). Analysis was performed with the program package MEGA4.0. The number at the branch point of the node represents the value resulting from 1000 replications and gaps were deleted with pairwise deletion method.
