Phylogenetic relationships between the insect strains jC^Aus, k10^U2, r13^U1, and Rm^tet of Callosobruchus chinensis. (A) Relationship of the insect strains deduced from their possession patterns of the transferred Wolbachia genes. (B) Relationship inferred from 522 aligned nucleotide sites of mitochondrial cytochrome oxidase I gene. (C) Relationship inferred from 590 aligned nucleotide sites of nuclear elongation factor 1α intron. (D) Relationship of the concatenated amino acid sequence of the 27 transferred Wolbachia genes based on 2929 aligned amino acid sites. NJ trees are shown, whereas ML and BA trees exhibit the same topologies. Support values >50% are indicated at the nodes.
