Sažetak
Poriferan mitochondrial DNA (mtDNA), especially large intergenic regions, is a target for the insertion of repetitive hairpin-forming elements. These elements are responsible for the large mt genome size differences observed even among closely related sponge taxa. In this study, we present the new, nearly complete, mt genome sequence of Ephydatia fluviatilis and compare it with previously published mt genomes of freshwater sponges. Special emphasis was placed on comparison with the closely related species Ephydatia muelleri, thereby comparing the only two species of the genus Ephydatia on the western Balkan Peninsula. In particular, we analyzed repetitive palindromic elements within the mitochondrial intergenic regions. The genomic distribution of these repetitive elements was analyzed and their potential role in the evolution of mt genomes discussed. We show here that palindromic elements are widespread through the whole mt genome, including the protein coding genes, thus introducing genetic variability into mt genomes.
