Abstract:
The complete mitochondrial genome sequence of Squalus brevirostri was determined using next-generation sequencing. The whole circular genome is 16,734 bp in length. It contains 37 genes including13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA genes (tRNA), and a control region (D-Loop). The overall nucleotide composition is A: 30.38%, T: 30.73%, G: 24.61%, and C: 14.27%, with an A + T content of 61.11%. The phylogenetic analysis suggested that S. brevirostris was closely related to Squalus montalbani.
