Complete mitochondrial DNA genome of triploid pengze crucian carp (Carassius auratus).

The complete mitochondrial genome sequence of triploid pengze crucian carp was 16,580 bp in length. The mitochondrial genome contains 22 transfer RNAs, 13 protein-coding genes, 2 ribosomal RNAs and 2 non-coding regions (control region and origin of light-strand replication). All genes were encoded on the heavy strain except for ND6 and eight tRNA genes. The overall base composition is A 31.53%, T 26.23%, G 16.15%, C 26.09%, with an A + T bias of 57.76%. The complete mtDNA sequence of the geographic triploid pengze crucian carp was reported in this study for the first time.
