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.

The phylogeny of Nereididae (Annelida) based on mitochondrial genomes

“…1) to 17,469 bp in Platynereis massiliensis . All genes were coded on the same strand, consistent with previously published Nereididae mitochondrial genomes (Boore & Brown, ; Chen, Li, et al, ; Kim, Choi, Kim, & Min, ; Kim et al, ; Kim, Kim, & Lee, ; Lin et al, , ; Park et al, , ; Seixas et al, ; Won et al, ). Appendix shows information on base composition and nucleotide bias in the mitochondrial genomes sequenced.…”

“…As of 2019, 11 complete Nereididae mitochondrial genomes had been published (Boore & Brown, ; Chen, Li, et al, ; Kim, Kim, & Lee, , ; Kim et al, ; Lin, Audira, & Hsiao, ; Lin, Shen, & Hsiao, ; Park, Lee, & Kim, ; Park, Lee, Shin, & Kim, ; Seixas, Paiva, & Russo, ; Won, Rhee, Shin, & Lee, ) and two distinct tRNA gene order arrangements have been recognized by Park et al () that vary in the position of the ATP8 gene and three tRNAs. These arrangements have been referred to as ‘Group 1’ with tRNA‐Tyr, ATP8, tRNA‐Met and tRNA‐Asp and ‘Group 2’ with tRNA‐Met, tRNA‐Asp, ATP8 and tRNA‐Tyr.…”
