Title

The absence of canonical respiratory complex I subunits in male-type mitogenomes of three Donax species

Abstract

Bivalves are an extraordinary class of animals in which species with a doubly uniparental inheritance (DUI) of mitochondrial DNA have been described. DUI is characterized as a mitochondrial homoplasmy of females and heteroplasmy of male individuals where F-type mitogenomes are passed to the progeny with mother egg cells and divergent M-type mitogenomes are inherited with fathers sperm cells. However, in most cases only male individuals retain divergent mitogenome inherited with spermatozoa. Additionally, in many of bivalves, unique mitochondrial features, like additional genes, gene duplication, gene extensions, mitochondrial introns, and recombination, were observed. In this study, we sequenced and assembled male-type mitogenomes of three Donax species. Comparative analysis of mitochondrial sequences revealed a lack of all seven NADH dehydrogenase subunits as well as the presence of three long additional open reading frames lacking identifiable homology to any of the existing genes.
