The complete mitochondrial genome of the polychaete, Goniada japonica (Phyllodocida, Goniadidae)

Abstract

The study determined the complete mitochondrial genome (mitogenome) of the polychaete, Goniada japonica, which was first reported in the family of Goniadidae. A total of 7162 reads were generated by Illumina HiSeq2500 platform (Illumina Inc., San Diego, CA) with an average depth of 58.41×. The mitogenome of G. japonica was 15,327 bp in size and consists of 37 typical genes (13 protein-coding genes, 2 rRNA genes and 22 tRNA genes) and a putative control region. All the 37 genes were encoded on the heavy strand whose nucleotide compositions were 35.08% of A, 33.69% of T, 11.66% of G, and 19.57% of C, showing a lower content of G + C (31.23%). The gene order of 15 major coding genes was identical to that of the Nereididae species. Phylogenetic analysis showed that G. japonica has a closer relationship with Tylorrhynchus heterochaetus of Nereididae.
