Study on the Role of Mitophagy Receptor PHB2 in Doubly Uniparental Inheritance of Hyriopsis cumingii
In bivalves, the heterogeneity of mitochondrial DNA and its unique mode of transmission have been the focus of attention, which is called doubly...

An Unusual Evolutionary Strategy: The Origins, Genetic Repertoire, and Implications of Doubly Uniparental Inheritance of Mitochondrial DNA in Bivalves
Mitochondrial DNA (mtDNA) is typically passed on to progeny only by the female parent. The phenomenon of “doubly uniparental inheritance” (DUI) of...
-
Variability of mitochondrial ORFans hints at possible differences in the system of doubly uniparental inheritance of mitochondria among families of freshwater mussels (Bivalvia: Unionida)
BackgroundSupernumerary ORFan genes (i.e., open reading frames without obvious homology to other genes) are present in the mitochondrial genomes of...

Presence of male mitochondria in somatic tissues and their functional importance at the whole animal level in the marine bivalve Arctica islandica
Metazoans normally possess a single lineage of mitochondria inherited from the mother (♀-type mitochondria) while paternal mitochondria are absent or...

Doubly Uniparental Inheritance of mtDNA: An Unappreciated Defiance of a General Rule
We recount the basic observations about doubly uniparental inheritance (DUI) of mtDNA in bivalvian mollusks with an emphasis on those that were...

Mendelian nightmares: the germline-restricted chromosome of songbirds
Germline-restricted chromosomes (GRCs) are accessory chromosomes that occur only in germ cells. They are eliminated from somatic cells through...

Wolbachia and Cardinium infection found in threatened unionid species: a new concern for conservation of freshwater mussels?
Endosymbiotic bacterial species that manipulate host biology, reproduction and mitochondrial genetic diversity have been identified in many...

Complete mitochondrial genome of freshwater pearl mussel Lamellidens marginalis (Lamarck, 1819) and its phylogenetic relation within unionidae family
BackgroundFreshwater mussels play a key role in ecology and are often considered as ecological indicators. Conversely, these molluscs are one of the...

A new molecular method for fast differentiation of cockles Cerastoderma edule and Cerastoderma glaucum
Cerastoderma edule and C. glaucum are two species of cockles that co-exist in European waters. They are morphologically similar but exhibit...

Morphological and molecular evidence for natural hybridization between Sorbus pohuashanensis and S. discolor (Rosaceae)
In overlap** distribution areas of Sorbus pohuashanensis and S. discolor in North China (Mount Tuoliang, Mount **ling and Mount Baihua), Sorbus ...

Mitochondrial genomic analyses provide new insights into the “missing” atp8 and adaptive evolution of Mytilidae
BackgroundMytilidae, also known as marine mussels, are widely distributed in the oceans worldwide. Members of Mytilidae show a tremendous range of...

Disruption of doubly uniparental inheritance of mitochondrial DNA associated with hybridization area of European Mytilus edulis and Mytilus trossulus in Norway
Doubly uniparental inheritance of mitochondria (DUI) is best known in the blue mussel Mytilus . Under this model, two types of mitochondrial DNA...

Mitochondrial Genome of Nonmodel Marine Metazoans by Next-Generation Sequencing (NGS)
Mitochondrial genomes (mtgenome) represent an important source of information for addressing fundamental evolutionary, phylogeographic, systematic,...

High heteroplasmy is associated with low mitochondrial copy number and selection against non-synonymous mutations in the snail Cepaea nemoralis
Molluscan mitochondrial genomes are unusual because they show wide variation in size, radical genome rearrangements and frequently show high...

Population decline of an endangered unionid, Pronodularia japanensis, in streams is revealed by eDNA and conventional monitoring approaches
Environmental DNA (eDNA) is useful to detect the presence of aquatic organisms from water samples, especially for rare and cryptic species. Two...

Sexual conflict explains the extraordinary diversity of mechanisms regulating mitochondrial inheritance
BackgroundMitochondria are predominantly inherited from the maternal gamete, even in unicellular organisms. Yet an extraordinary array of mechanisms...
-
Plastome phylogenomics provide new perspective into the phylogeny and evolution of Betulaceae (Fagales)
BackgroundBetulaceae is a relatively small but morphologically diverse family, with many species having important economic and ecological values....

Doubly uniparental inheritance and highly divergent mitochondrial genomes of the freshwater mussel Unio tumidus (Bivalvia: Unionidae)
Unio tumidus is a native European freshwater mussel from the family Unionidae. These mussels have a unique system of mitochondrial DNA inheritance...

Complex mitogenomic rearrangements within the Pectinidae (Mollusca: Bivalvia)
BackgroundScallops (Bivalvia: Pectinidae) present extraordinary variance in both mitochondrial genome size, structure and content, even when compared...

Stable isotope analysis reveals trophic segregation between the invasive zebra mussel Dreissena polymorpha and the native duck mussel Anodonta anatina in Lake Trasimeno (Italy)
Non-indigenous freshwater bivalves negatively affect invaded ecosystems through different mechanisms, including inter-specific competition for...
