The complete mitochondrial genome of Chionoecetes japonicus (Crustacea: Decapoda: Majoidea)

Abstract

The complete mitochondrial genome of Chionoecetes japonicus was sequenced using a specimen collected offshore in the East Sea. The genome includes 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a control region (D-loop), with a total length of 16,060 bp. The overall nucleotide composition was 34.91% A, 17.29% C, 10.93% G, and 36.87% T, with 71.78% A þ T. In the phylogenetic tree was constructed using maximum-likelihood and Bayesian inference analyses, C. japonicus and C. japonicus pacificus formed a genetic clade that was sister to C. opilio.

The complete mitochondrial genome of Scyra compressipes Stimpson, 1857 (Decapoda: Epialtidae)

“…The molecular phylogeny suggested that S. compressipes clustered with Maguimithrax spinosissimus, a representative of the Mithracidae (Figure 1). The molecular phylogenetic relationship between families in the superfamily Majoidea presented in this study was consistent to previous studies (Hultgren and Stachowicz 2008;Jeong et al 2020;Kim et al 2020).…”
