TITLE
3 new mitochondrial genomes of genus Mytilus of Bivalves. Phylogenetics and evolution of Doubly Uniparental Inheritance.
ABSTRACT
In animal species, mitochondrial DNA is inherited exclusively from the mother to sons and daughters (maternal inheritance). Several bivalve species are known to have two highly differentiated mitochondrial genomes, one of which follows the standard maternal inheritance (and is known as type F for female- transmitted) and the other is transmitted through the sperm (and is known as M for male-transmitted). This phenomenon is known as Doubly Uniparental Inheritance, or DUI. DUI has important consequences for the evolution of mitochondrial DNA in bivalve species. In the current study, 3 new mitochondrial genomes of the genus Mytilus are presented (M.trossulus M, M.californianus F and M). By using the new genomes together with 3 already published full mitochondrial genome sequences of the genus (M.edulis F and M, M.trossulus F), we propose hypotheses about the ways natural selection has acted on mitochondrial DNA in the context of DUI and infer the phylogenetic history of the genomes. The M were found to evolve faster than the F genomes, but no M-specific amino acids were found that could imply adaptive evolution of the M genome. Different areas of the genomes produced different phylogenies because of bias introduced by natural selection acting on them. The phylogeny of the genomes which is described, includes one event of masculinization in the common ancestor of Μ.edulis and M.trossulus species.
