title: Complete mitochondrial genome of the blue shark Prionace glauca (Elasmobranchii: Carcharhiniformes).
abstract: In this study, we first presented the complete mitochondrial genome of the blue shark Prionace Glauca, a pelagic and oceanic species. It is 16,705 bp in length and contains 2 rRNA genes, 22 tRNA genes, 13 protein-coding genes and 1 putative control region. The overall base composition is 31.6% A, 24.4% C, 13.1% G and 30.9% T. Overlaps and short inter-genic spaces are located in the genome. The tRNA-Ser2 loses the dihydrouridine arm and cannot be folded into the typical clover-leaf secondary structure. Two start codons (GTG and ATG) with two stop codons (TAG and TAA) or with one incomplete stop codon (T) are found in the 13 protein-coding genes. The control region contains high A + T (69.9%) and low G (12.0%).
