Full-length mitochondrial genome of the triton trumpet Charonia lampas (Littorinimorpha: Ranellidae)

Abstract

The full-length mitochondrial genome of the triton trumpet Charonia lampas (Linnaeus, 1758) was analyzed by the primer walking method. Its mitogenome is 15,382 bp in length, comprising 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The gene order of C. lampas is congruent with those previously reported for the infraorder Littorinimorpha. This is the first full-length mitogenome sequence for the genus Charonia. In the phylogenetic tree, C. lampas formed a monophyletic group with the other species of the superfamily Tonnoidea, but did not show the closest phylogenetic relationship to a species from the same family, Ranellidae.

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

“…Compared to the mitochondrial genome of C. lampas first characterized from South Korea (Cho et al. 2017 ), there exhibits 98% nucleotide similarity between the two: the 2% differences are not observed in specific genes, but scattered across the genes.…”

“…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.…”

“…KU237290), which is 15,330 bp in length, exhibits identical gene components and order to those of Charonia tritonis (MT043269) as well as C. lampas (NC_037188; Cho et al. 2017 ). It contains 37 genes including 13 PCGs including COX1 − 3 , ND1 − 6 , ND4L , CYTB , ATP6 , and ATP8 , 2 rRNAs including 16S rRNA and 12S rRNA , 22 tRNAs, of which 30 genes place on the heavy strand and the remaining seven genes are located on the light strand.…”

The complete mitochondrial genome of Echinoecus nipponicus Miyake, 1939 (Crustacea: Decapoda: Pilumnidae), a symbiont of sea urchins

“…As in the method of Cho et al (2017), the complete mitochondrial genome sequence was amplified by conducting two independent and overlapping PCR runs with forward and reverse primers. The PCR products were purified and directly sequenced using a set of 23 sequencing primers designed for this study.…”
