The complete mitochondrial genome of Saccostrea malabonensis (Ostreida: Ostreidae): characterization and phylogenetic position

The taxonomy of the genus Saccostrea is very confused, however, there is relatively little molecular information available on Saccostrea. In this study, we determined and described for the first time the complete mitochondrial genome of Saccostrea malabonensis. The complete mitogenome of S. malabonensis is 16,204 bp in length, containing 12 protein-coding genes (lack of atp8 gene), two rRNA genes, 23 tRNA genes. The overall nucleotide composition of S. malabonensis has an AT content of 61.94% (26.29% A, 15.71% C, 22.35% G, 35.65% T). Phylogenetic analyses showed that S. malabonensis is first clustered with S. cucullata then united with Saccostrea kegaki.
