The complete mitochondrial genome sequence of Diptychus maculatus Ste'mdachner [Cyprlnlformes: Cyprinidae)

摘要

Diptychus maculatus {Cypriniformes: Cyprinidae), the sole species of genus Diptychus, is an economically important freshwater fish widely distributed in hsia. In this study, we first sequenced the complete mitochondrial genome of D. maculatus. The genomeis 16,835 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes as well as 2 non-coding regions: origin of light-strand replication (Ou) and control region (D-loop). The gene composition and order are identical with most bony fishes. The overall nucleotide composition of the heavy strand is 27.7% A, 26.7% T, 26.5% C and 19.1% G. The mitogenome data would be useful for further genetics studies, phylogenetic analysis, and resource protection of D. maculatus andphylogenetic analysis of Schizothoracine fishes.
