Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <p>The mitochondrial genome sequence of <italic>Coelomactra antiquata</italic> (Mollusca: Bivalvia) in Zhangzhou (zz-mtDNA) was fully sequenced and compared with that in Rizhao (rz-mtDNA) in this study. A tRNA (<italic>tRNA</italic>^{<italic>Met</italic>}) located between <italic>tRNA</italic>^{<italic>Ala</italic>} and <italic>cox1</italic> genes was identified in zz-mtDNA but not in rz-mtDNA. The largest non-coding region (NCR; MNR) contained 11 copies 99nt tandem repeat sequences exclusively in rz-mtDNA, while the second largest NCR with 400 bp between <italic>tRNA</italic>^{<italic>Ala</italic>} and <italic>tRNA</italic>^{<italic>Met</italic>} in zz-mtDNA was absent in rz-mtDNA. Secondary structures of ZZ and RZ <italic>C. antiquata</italic> rRNAs are significantly different. The mitochondrial genomic characteristics clearly indicate that there are at least two subspecies in <italic>C. antiquata</italic>.</p> </abstract>
