Mitochondrial DNA sequence of the hybrid of Squaliobarbus curriculus (♀) x Ctenopharyngodon idella (♂)

In this work, we reported the complete mitochondrial DNA sequence of the hybrid of Squaliobarbus curriculus (female) x Ctenopharyngodon idella (male), which was obtained by artificial hybridization. The total length of the mitochondrial genome is 16,616 bp, with the base composition of 31.15% A, 25.02% T, 27.66% C, and 16.17% G. It contains 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and a major non-coding control region (D-loop region). The arrangement of these genes is the same as that found in the teleosts. All the protein initiation codons are ATG, except for COX1 that begins with GTG. The complete mitogenome of the hybrid of S. curriculus (female) x C. idella (male) provides an important data set for the study in genetic mechanism.
