The complete mitochondrial genome of a freshwater mussel Nodularia douglasiae (Bivalvia: Unionidae)

Abstract

The circular F-type mitochondrial genome (15,761 bp) was completely sequenced for a Korean freshwater mussel Nodularia douglasiae (synonym Unio douglasiae; Unionidae, Unionida, Bivalvia). It contains 13 PCGs, two rRNA genes, and 22 tRNA genes, as generally shown in metazoan mitochondrial genomes. Its gene order is identical to that of F-type mitochondrial genomes observed in other freshwater mussels. With nucleotide and amino acid sequences of the complete F-type mitochondrial genomes obtained from 38 unionid species reported so far, phylogenetic analyses were done and discussed. The present study may give valuable helps to explore genetic diversity and population structures of other freshwater mussels as well as N. douglasiae.

Molecular phylogenetic, population genetic and demographic studies of Nodularia douglasiae and Nodularia breviconcha based on CO1 and 16S rRNA

“…N. douglasiae has a bigger shell size than N. breviconcha . N. douglasiae is widely distributed throughout East Asia, while N. breviconcha is known to be a native species inhabiting only the Korean Peninsula 11 , 22 . N. breviconcha had previously been treated as a subspecies of N. douglasiae 21 , 23 , but it was recently revealed that these two species may be genetically and phylogenetically separated from each other 10 , 12 , 20 , 24 .…”

The complete mitochondrial genome of an endangered triton snail Charonia lampas (Littorinimorpha: Charoniidae) from South Korea

“…Among them, a marine snail Charonia lampas (Linnaeus, 1758) is registered as endangered and protected by law in South Korea since it has dramatically declined in its occurrence and population size, according to the report of the National Institute of Biological Resources. In mollusk phylogenetic and population genetic researches, mitochondrial genome information has been known to be useful (Hwang and Kim 1999;Hilgers et al 2016;Cho et al 2017;Cha et al 2018;Kim and Lee 2018;Jiang et al 2019;Choi et al 2017). In this study, we characterized the complete mitochondrial genome of the endangered C. lampas, expecting that the result will provide helpful information for making a conservation plan of the species in South Korea.…”

The mitochondrial genome of an Endangered freshwater snail Koreoleptoxis nodifila (Caenogastropoda: Semisulcospiridae) from South Korea

“…During the last decades, mitochondrial genomes have been considered useful phylogenetic markers in mollusks (Lee et al 2012;Zeng et al 2015;Hilgers et al 2016;Cha et al 2018;Kim and Lee 2018;Jiang et al 2019;Lee et al 2019;Tenorio et al 2020). Here, we characterized a nearly complete mitochondrial genome of the Endangered freshwater snail Koreoleptoxis nodifila (Martens 1886).…”
