title: Complete mitochondrial genome of the Antarctic barnacle Lepas australis (Crustacea, Maxillopoda, Cirripedia).
abstract: We present the complete mitochondrial genome of the Antarctic barnacle Lepas australis (Cirripedia, Thoracica, Lepadidae). The genome sequence is 15,502 bp in size. Except for CO1, 12 protein-coding genes (PCGs) start with an ATN initiation codon (ATA, ATG, ATC and ATT). Twelve PCGs were terminated with TAA or TAG stop codon, whereas ND1 possessed an incomplete termination codon (T- -). We compared the mitogenome structure of L. australis to those of other cirripeds and a typical arthropod Homarus americanus. The PCGs in the L. australis mtgenome showed a typical gene arrangement, identical to the arthropod pattern in other cirriped genomes. However, at least 8 tRNA genes were translocated and 2 tRNA genes were inverted in the coding polarity. Unique differences in L. australis mtgenome included translocation of trnS2, trnD and trnI. These results are useful for understanding the phylogenetic relationships among cirripedians, and additional mtgenome information of barnacles including the polar species would allow exploration of the thoracican relationships and mtgenome modifications in the barnacle evolution.
