Complete mitochondrial genome of the northern mauxia shrimp Acetes chinensis (Decapoda, Dendrobranchiata, Sergestoidae)

Abstract

Here, we report the first complete mitochondrial genome sequence of northern mauxia shrimp Acetes chinensis (Decapoda, Dendrobranchiata, Sergestoidae). The genome sequence was 15,740 bp in size, and the gene content, gene order and transcriptional polarity were almost identical to the pancrustacean ground pattern, with the one exception that an extra trnS₁^AGC was adjacent to the original trnS₁^AGA. The two tandemly duplicated trnS₁ showed a high sequence similarity (82.3%), with almost identical secondary structure lacking a DHU arm. Comparison of codon usage suggests that both of the trnS₁ genes were functional.
