Fig. 2. Phylogenetic trees based on the sequences of mitochondrial cytochrome c reductase (mtCOI) gene from hosts and 16S rRNA gene from endosymbionts in two populations of Alviniconcha marisindica.

Fig. 2

The phylogenetic trees were constructed by the neighbor-joining method using MEGA5 software [45] based on the mtCOI gene sequence (544 base position) (a) and using the ARB software package [44] based on 16S rRNA gene sequences (1402 base position) (b). The mtCOI gene sequences obtained from A. marisindica individuals in this study have been indicated in bold. The mtCOI genes of Ifremeria nautilei from North Fiji Basin (AB235214) and Manus Basin (AB235217) [22] were used as an outgroup for this tree. The 16S rRNA gene sequences obtained from A. marisindica individuals in this study have been indicated in bold. The 16S rRNA gene of Aquifex aeolicus (AJ309733) was used as an outgroup of this tree.
