Abstract:
Pterosagitta draco is an important predator in many food webs, and so maintaining the diversity study of Pterosagitta draco in marine ecosystem is essential. In this paper, the complete mitochondrial genome sequence of Pterosagitta draco was determined. Its complete mtDNA sequence is 10,426 bp in length, which contains 11 protein-coding genes (PCGs), 6 transfer RNA genes and 2 ribosomal RNA genes. The composition of A, T, G, C in mtDNA is 27.63%, 23.61%, 23.53% and 25.23%, respectively. The percentage of A + T is 51.24%. The complete mitochondrial genome sequence would be useful for further phylogenetic analysis in Pterosagitta draco.
