Abstract:
We firstly presented the complete mitogenome of the spadenose shark Scoliodon macrorhynchos (Carcharhinidae, Carcharhiniformes). The mitogenome is 16,693 bp long and contains 13 protein-coding genes, two rRNAs, 22 tRNAs and one control region, a typical vertebrate arrangement. The codon usage bias was different between the H-strand and L-strand encoded protein genes. All tRNA genes have the typical cloverleaf secondary structure excepting tRNA-Ser2, in which the dihydrouridine (DHU) arm is replaced by a simple loop with 12 unpaired nucleotides. A termination associated sequence and three conserved sequence blocks (CSB I-III) were identified in the control region, which were considered associating with the replication and transcription of mitogenome.
