The complete mitochondrial genome of Dosinia japonica (Bivalvia: Veneridae)

Comparative analyses of the complete mitochondrial genomes of Dosinia clams and their phylogenetic position within Veneridae

“…Based on the sequences of above fragments and the complete mitogenome of D . japonica [ 10 ], long-PCR primers were designed and employed to amplify the entire mt genomes ( Table 1 ).…”

“…Along with morphological classification, molecular analyses are essential for evaluating the diversity of metazoans because of their high informativeness and accuracy [ 3 , 4 ]. However, in contrast to the large number of morphological descriptions of Dosinia , there have been few attempts to perform molecular phylogenetic analysis in this genus so far [ 5 – 10 ]. Most present work involving Dosinia clams used different gene sequences (e.g., ITS2, H3, rrnL ) to resolve the phylogenetic relationships at the level of Heterodont or Veneroida, nevertheless, the accuracy of phylogenies reconstructed from single gene sequences is low due to substitutional saturation of nucleotide and horizontal gene transfer [ 11 , 12 ].…”

“…Recently, the number of available complete mitogenome sequences has increased considerably. However for the Dosinia genus, only one mt genome is available ( Dosinia japonica ) to date [ 10 ], and more mitogenome sequences from various Dosinia species are required for further analysis. The mt genome of D .…”

“…The mt genome of D . japonica contains 37 genes including 13 for protein subunits of oxidative phosphorylation enzymes ( cox1-3 , cytb , atp6 , atp8 , nad1-6 and nad4l ), 22 transfer RNA genes necessary for translating 13 proteins, and two ribosomal RNA genes ( rrnL and rrnS ) [ 10 , 26 ].…”

“…troscheli (Lischke, 1873), and compared them with that of D . japonica [ 10 ]. The gene arrangements were compared among three Dosinia species, together with the other 12 Veneridae species.…”
