Complete mitochondrial genome of smoothshell shrimp Parapenaeopsis tenella (Bate, 1888) (Crustacea: Decapoda: Penaeidae)

Abstract

In this study, the complete mitochondrial genome of smoothshell shrimp Parapenaeopsis tenella was determined for the first time. The mitogenome of P. tenella is 15,893 bp in length and encodes 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and a control region (CR). The overall base composition is 34.0%, 35.3%, 11.9%, and 18.9% for A, T, C, and G, respectively. All PCGs are initiated by ATN codons. Four of the 13 PCGs harbor the incomplete termination codon by T. Twenty-one tRNA genes have a typical clover-leaf structure of mitochondrial tRNA, except for tRNA-Ser (AGC), in which the dihydrouridine (DHU) arm stem is absent. Phylogenetic analysis among the available malacostracans species supports the current morphology-based hypothesis that P. tenella is grouped to the genus Parapenaeopsis.
