Unique mitochondrial gene rearrangement in corals
Unique mitochondrial gene rearrangement in caryophylliid scleractinian corals
Traditional Caryophylliidae has been known as the most speciose scleractinian coral family. Mito/nuclear phylogenomics point that some caryophylliids that form a clade (“true” Caryophylliidae) have unique mt gene rearrangement: a transposition of the gene block containing cob, nad2, and nad6, which is located between nad5 5’ exon and trnW. Such mitochondrial gene rearrangement is proposed as a synapomorphy of “true” Caryophylliidae. Skeletal microstructure provides additional support for distinct position of “caryophylliids” with or without the mitochondrial gene rearrangement.
