Abstract
The complete mitochondrial genome of the hybrid of Megalobrama amblycephala (♀) × Ancherythroculter nigrocauda (♂) is 16,623 bp in size, consisting of 13 protein coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes, and 2 main non-coding regions. As in other vertebrates, most mitochondrial genes are encoded on the heavy strand, except for ND6 and 8 tRNAs. The overall nucleotide composition was 31.23% A, 24.68% T, 27.90% C, and 16.19% G, with an A + T content of 55.91%. The mitochondrial genome sequence data may provide useful information for the elucidation of evolutionary mechanisms in the hybrid fish of Cyprinidae.
