Comparative mitochondrial genomic analyses of three chemosynthetic vesicomyid clams from deep-sea habitats.

ABSTRACT: Vesicomyid clams of the subfamily Pliocardinae are among the dominant chemosymbiotic bivalves found in sulfide-rich deep-sea habitats. Plastic morphologies and present molecular data could not resolve taxonomic uncertainties. The complete mitochondrial (mt) genomes will provide more data for comparative studies on molecular phylogeny and systematics of this taxonomically uncertain group, and help to clarify generic classifications. In this study, we analyze the features and evolutionary dynamics of mt genomes from three Archivesica species (Archivesica sp., Ar. gigas and Ar. pacifica) pertaining to subfamily Pliocardinae. Sequence coverage is nearly complete for the three newly sequenced mt genomes, with only the control region and some tRNA genes missing. Gene
