The complete mitochondrial genome of the marine polychaete: Perinereis aibuhitensis (Polychaeta, Nereididae)

Abstract

We determined the complete mitochondrial genome sequence of the marine polychaete Perinereis aibuhitensis (Grube, 1878) (Polychaeta, Phyllodocida, Nereididae), the dominant species in the inter-tidal mudflat of Korea, China, Philippines, Indonesia and India. The complete genome of P. aibuhitensis is 15,852bp in size including 13 protein coding genes, 2 rRNA and 22 tRAN with the same gene order and structure as those of other Nereididae species. The nucleotide composition of the genome is 29.5% A, 21.2% C, 14.1% G, 35.2% T, showing a high content of A + T similar to the other Phyllodocid polychaetes. In the protein-coding genes, G is the least used base in the third codon position (6.7%). All protein coding genes use ATG as the start codon. For the stop codon, COI and ND1 use incomplete codons of T. The mitogenome sequence of the P. aibuhitensis is the second one known in the genus Perinereis after P. nuntia, which will provide useful information for understanding evolutionary history and phylogenetic relationship of the genus Perinereis within the family, Nereididae.donesia and India.
