Determination of complete mitogenome sequence for Eastern Asian population of Cheilonereis cyclurus (Harrington, 1897) (Polychaeta: Nereididae)

Abstract

Complete mitogenome sequence for eastern Asian population of Cheilonereis cyclurus (Polychaeta: Nereididae) was determined for the first time. The length of circular genome of C. cyclurus is 14,917 bp including 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and a non-coding region of 383 bp. The gene order of C. cyclurus is identical to that of the following four nereidid species: Hediste diadroma, Namalycastis abiuma, Paraleonnates uschakovi, Tylorrhynchus heterochaetus. The phylogenetic position of C. cyclurus compared to 16 selected polychaetes was conducted and present species is closely related to the clade containing Perinereis nuntia, P. aibuhitensis, and Platynereis dumerilii with high bootstrap value.
