Complete mitochondrial genome of the calanoid copepod Eurytemora affinis (Calanoida, Temoridae)

The complete mitochondrial genome was sequenced from the calanoid copepod Eurytemora affinis. The sequenced total genome size was 18,553 bp. The mitochondrial genome of E. affinis has 13 protein-coding genes (PCGs), two rRNAs, and 22 tRNAs. Of 13 PCGs, ND1, ND5, and ATP6 genes had incomplete stop codons TA-, T-, and TA-, respectively. Furthermore, the stop codons of the remaining eleven PCGs were TAG or TAA while the start codon of 13 PCGs was ATG (Cytb, ATP8, ATP6, and CO3 genes), ATT (CO1, ND2, ND3, ND4L, ND5, and ND6 genes), and ATA (ND1, ND4, and CO2 genes), respectively. The ratio of A + T and G + C nucleotides of 13 PCGs of E. affinis mitogenome showed 63.9% and 36.1%, respectively while those ratio of the entire sequences were 65.5% and 34.5%, respectively.
