The complete mitochondrial genome of Japanese spear lobster Linuparus trigonus (Von Siebold, 1824)

Abstract

In this study, we first determined and characterized the complete mitochondrial genome of Japanese spear lobster Linuparus trigonus from South China Sea. The L. trigonus mitogenome is 15,949 bp long, and consists of 22 tRNA genes, 2 rRNA genes, 13 protein-coding genes (PCGs), and 1 control region. The nucleotide composition of L. trigonus mitogenome is significantly biased (A, G, T, and C was 32.80%, 12.01%, 32.63%, and 22.56%, respectively) with A + T contents of 65.43%. Two PCGs used an unusual initiation codon, and most PCGs were terminated with an abnormal stop codon except ATP8. Three microsatellites were identified in L. trigonus mitogenome sequences. Phylogenetic tree showed that L. trigonus was first clustered with Puerulus angulatus.
