The complete mitochondrial genome of the hybrid of Ctenopharyngodon idella (♀) ×  Squaliobarbus curriculus (♂).

The complete mitochondrial genome sequence of the hybrid of Ctenopharyngodon idella (♀) ×  Squaliobarbus curriculus (♂) was determined using PCR-based method. The total length of the mitogenome is 16,609 bp. It contains the typical structure as that of most other vertebrates, including 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes, and 1 non-coding control region (D-loop region). The overall composition of the mitogenome was estimated to be 31.86% for A, 26.08% for T, 26.38% for C, and 15.68% for G, respectively, indicating that an A+T (57.94%)-rich feature occurs in the hybrid mitogenome. Both the termination-associated sequence and three conserved sequence blocks (CSB1, CSB2, and CSB3) were also detected in the D-loop region. [ABSTRACT FROM AUTHOR]
