The complete mitochondrial genome of the polychaete, Marphysa tamurai (Eunicida, Eunicidae)

Abstract

The study determined the first complete mitochondrial genome (mitogenome) of the polychaete, Marphysa tamurai. A total of 21,346 reads were generated by Illumina HiSeq2500 platform with an average depth of 175.97×. The mitogenome of M. tamurai was 15,163 bp in size and consists of 38 typical genes, including 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes and 1 D-loop region. All the 38 genes were encoded on the heavy strand whose nucleotide compositions were 30.23% of A, 30.40% of T, 12.59% of G, 26.78% of C, showing a lower content of G + C (39.37%). Phylogenetic analysis showed that M. tamurai had a closer relationship with Marphysa sanguinea of Nereididae.
