Abstract
Parabramis pekinensis strenosoma belongs to the family Cyprinidae. In the present study, we obtain the complete mitochondrial genome of P. pekinensis strenosoma by PCR amplification and DNA sequencing. It is a circular double-stranded DNA molecule of 16,623 base pairs in length, consisting of the typical structure of 22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNA genes, as well as 2 main non-coding regions (the control region and the origin of the light strand replication). Compared with Parabramis pekinensis, the two different subspecies share 99.58% nucleotide sequence similarity and the biggest nucleotide sequence discrepancy between homologous genes are observed in ND2 for protein-coding genes and in tRNA-Ala for tRNA-coding genes. The complete mitochondrial genome sequence data are of great use for phylogenetic analysis and studies of population genetics and germplasm resources of P. pekinensis strenosoma.
