Abstract
    The complete DNA sequences of three mitochondrial (mt) genomes were obtained from the scleractinian corals, Stylophora pistillata, Pocillopora damicornis, and Madracis mirabilis, and were compared to the published mt genomes to elucidate phylogenetically unique features of the family Pocilloporidae. The entire mt genomes of pocilloporid corals ranged from 16,951 to 17,425 bp with the A+T contents of their sense strands ranging from 68.4% to 70.2%. The gene order of protein-coding genes was identical to those of other scleractinian corals. The novel atp8 gene, first described in confamilial Seriatopora corals, was also confirmed using reverse transcription-polymerase chain reaction (RT-PCR), Northern blot, and sequence analyses in other genera of the Pocilloporidae. The intergenic spacer between atp6 and nad4, containing distinct repeated elements, conserved sequence blocks and domains, and functional structures, possesses typical characteristics of a putative control region for the four coral genera. A duplicated trnW, detected in the region close to the cox1 gene and which shares the highly conserved primary and secondary structures of its original counterpart, was discovered in both Seriatopora and Stylophora. These molecular characteristics are unique and provide the phylogenetic information for future evaluation of the status of the family Pocilloporidae in the evolutionary history of scleractinian corals.
