The complete mitochondrial genome of the marine polychaete: Hediste diadroma (Phyllodocida, Nereididae)

The mitogenome sequence of a polychaete Hediste diadroma (Phyllodocida, Nereididae) was determined first in the genus Hediste. The circular genome is 15,765bp in size including 13 protein-coding genes (PCGs), 2 rRNA and 22 tRNA of which the order and structure is same as those of other Nereididae species. All PCGs use ATG as the start codon while for the stop codon, COI, ND5 and ND1 use an incomplete codon of T. The genome consists of 32.4% A, 18.2% C, 14.2% G, 35.2% T, showing a high content of A + T similar to the other Phyllodocid polychaetes.
