The complete mitochondrial genome of the marine polychaete: Hediste diadroma (Phyllodocida, Nereididae)

Abstract

The mitogenome sequence of a polychaete Hediste diadroma (Phyllodocida, Nereididae) was determined first in the genus Hediste. The circular genome is 15,765bp in size including 13 protein-coding genes (PCGs), 2 rRNA and 22 tRNA of which the order and structure is same as those of other Nereididae species. All PCGs use ATG as the start codon while for the stop codon, COI, ND5 and ND1 use an incomplete codon of T. The genome consists of 32.4% A, 18.2% C, 14.2% G, 35.2% T, showing a high content of A þ T similar to the other Phyllodocid polychaetes. Figure 1. Neighbour-joining tree for six species of the family Nereididae including Hediste diadroma and five other related species in Phyllodocida inferred from mitochondrial genomes. Terebellides stroemi (EU236701) derived from Terebellida was used as outgroup for tree rooting. Data set for Phylogenetic trees were used nucleotide sequences of 13 protein-coding genes. Numbers above the branches indicate NJ bootstrap values from 1000 replication. ARTICLE HISTORY KEYWORDS

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.…”

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

“…Also, the comparison of partial mitochondrial COI sequences revealed significant difference between east and west north Pacific populations ( Figure 1(A); personal data of the author). Although, the comparison of complete mitogenome sequence may provide more valuable evolutionary information for phylogenetic studies (Chen et al 2016), only seven nereidids are available (Boore 2001;Won et al 2013;Kim et al 2014;Chen et al 2016;Kim et al 2016;Lin et al 2016;Park et al 2016). The purpose of this study was to determine the complete mitogenome sequence for eastern Asian population of C. cyclurus.…”

The complete mitochondrial genome of epitokous Nereis species (Phyllodocida, Nereididae) from Dok-do, Korea

“…by the Sanger method using each universal primer sets regarding the partial cox1, cox3, cytb, nad4 and 16S ribosomal RNA (rRNA) genes. The sequences were assembled and annotated in comparison with the previously reported mitogenome sequences of nereidid species (Boore 2001;Kim et al 2015Kim et al , 2016) using Geneious 9.1.8 (Kearse et al 2012). The phylogenetic tree was constructed using MEGA6 (Tamura et al 2013).…”
