The complete mitochondrial genome of Acanthastrea maxima (Cnidaria, Scleractinia, Lobophylliidae). Sclerophyllia maxima

The complete nucleotide sequence of the mitochondrial genome of the scleractinian coral Acanthastrea maxima has been obtained, representing the first sequenced mitogenome of a member of the Lobophylliidae. The mitochondrial genome is 18168 bp in length, the longest sequence among the robust corals sequenced mitogenome to date. The overall AT composition (66.3%) and the gene arrangement are similar to those of the others scleractinian corals, including 13 protein-coding genes, two rRNA genes (rnl and rns) and two tRNA genes (tRNA-Met and tRNA-Trp). All genes except tRNA-Trp, atp8, cox1, tRNA-Met and rnl are engulfed by a large group I intron in the nad5 gene. A second group I intron of 1077 bp in length is inserted in the cox1 gene and it encodes a putative homing endonuclease, as reported for other robust corals. There are four regions of gene overlaps totalling 22 bp and nine intergenic spacer regions for a total of 2111 bp, of which the cox3-cox2 region may correspond to the putative control region of A. maxima.
