Abstract

The complete mitochondrial genome was sequenced from the marine water flea Diaphanosoma celebensis. The sequenced mitochondrial genome size was 17,060 bp, possessing identical gene order of 13 protein-coding genes (PGCs) to those of the congeneric freshwater species Diaphanosoma dubium in the genus Diaphanosoma. The mitochondrial genome of D. celebensis had 13 PGCs, two rRNAs, and 22 tRNAs. Of 13 PGCs, three genes (CO3, ND3, and ND4) had incomplete stop codons. Furthermore, the stop codons of the remaining ten PGCs were TAA (for CO1, ATP8, ATP6, ND5, ND6, and ND1) and TAG (for NL4L, Cytb, and ND2). The second and third base composition of codon on 9 PCGs on the L strand in D. celebensis mitogenome showed an anti-G bias (11.0% and 15.0%), respectively.

Keywords: Diaphanosoma celebensis; complete mitochondrial DNA.
