The complete mitochondrial genome of the mysid shrimp, Neomysis japonica (Crustacea, Malacostraca, Mysida)

Abstract

In this study, we determined the mitogenome sequence of Neomysis japonica (Crustacea, Malacostraca, Mysida), which is the first complete mitogenome sequence in the order Mysida. The mitogenome of N. japonica is 17,652 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and a control region (CR). Mitogenome analysis of N. japonica revealed a novel gene order that included inversions in three PCGs and five tRNAs, compared with H. americanus, the ancestral pancrustacean ground pattern. The results will be useful for the detailed study of mitogenome evolution and the phylogenetic relationships among the orders in the class Malacostraca. As seen from the phylogenetic tree, N. japonica belongs to the order Mysida within Malacostraca.

The complete mitochondrial genome of the Antarctic marine triclad, Obrimoposthia Wandeli (Platyhelminthes, Tricladida, Maricola)

“…Collected flatworms were transferred live to the laboratory and starved for a week to ensure that DNA from other organisms was not extracted during the DNA extraction step. Mitochondrial DNA extraction, sequencing, and gene annotation were performed using the methods described by Song et al (2016). The extracted mitochondrial DNA was deposited in the DNA collection at the National Institute of Biological Resources, Incheon, South Korea (deposit no.…”

The complete mitochondrial genome of squat lobster, Munida gregaria (Anomura, Galatheoidea, Munididae)

“…Among them, one specimen was deposited in the Korea Polar Research Institute (KOPRI, Incheon, South Korea). Genomic DNA extraction, sequencing and gene annotation were performed according to the methods described by Song et al (2015). Phylogenetic tree was constructed using MEGA 6.0 (MEGA Inc., Englewood, NJ) (Tamura et al 2013).…”

Complete mitochondrial genome of the marine mysid Siriella sp. (Crustacea, Mysida, Mysidae)

“…Mysids have been recognized as a model species for toxicity test, ecotoxicology, and environmental research due to several promising features, which include small size, fast growth rate with high productivity, sensitivity, high adaptability to diverse ranges of seawater conditions, feasibility of multi-generation test, good representatives of shrimp, and ease of aquaculture in the laboratory (Verslycke et al 2004;Hirano et al 2009;Do et al 2018;Haque et al 2018;Kim et al 2018;Min et al 2018). Despite the high species diversity and abundance of the order Mysida, only several studies have been investigated on characteristics and organization of whole mitogenomes (Shen et al 2015;Song et al 2016). Previously, 77 species have been recorded in the genus Siriella Dana, 1850 in the world (Murano and Fukuoka 2008), and the genus is divided into 9 groups with 5 subgroups that comprise 8 known species in the coastal regions of Korea (Lee et al 2017).…”
