From: Functional analysis of the ATP-binding cassette (ABC) transporter gene family of Tribolium castaneum
Phylogenetic tree for T. castaneum ABC transporters. The maximum likelihood tree was calculated on the basis of a ClustalW alignment (Blosum62) of nucleotide binding domains from different ABC transporters of T. castaneum. The scale bar indicates an evolutionary distance of 0.5 amino acid substitutions per site. Bootstrap values are given in percentages at the internodes. Different ABC transporter subfamilies are indicated by colored shadings.
