- We determined the first complete mitochondrial genome sequence of Potamotrygon motoro from South American freshwater stingrays. The total length of P. motoro mitogenome is 17,448 bp, which consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a control region, with the genome organization and gene order being identical to that of the typical vertebrate. The overall nucleotide composition is 32.3% A, 24.4% T, 30.5% C and 12.8% G. These data will provide useful molecular information for phylogenetic relationships within the family Potamotrygonidae species. |
