The first animal mitochondrial genomes to be sequenced were of several vertebrates and
model organisms, and the consistency of genomic features found has led to a 'textbook …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

Our understanding of disease processes and host–pathogen interactions in model species
has benefited greatly from the application of medium and high-throughput genomic …

Heteroplasmy is the presence of more than one type of mitochondrial genome within an
individual, a condition commonly reported as unfavorable and affecting mitonuclear …

Maternal immunity refers to the immunity transferred from mother to offspring via egg,
playing an important role in protecting the offspring at early life stages and contributing a …

Typically, animal mitochondria have very compact genomes, with few short intergenic
regions, and no introns. Hence, it may seem that there is little space for unknown functions in …

Mitochondrial ORFans (open reading frames having no detectable homology and with
unknown function) were discovered in bivalve molluscs with doubly uniparental inheritance …

Bivalves exhibit an astonishing diversity of sexual systems and sex-determining
mechanisms. They can be gonochoric, hermaphroditic or androgenetic, with both genetic …

Bivalve mitochondrial genomes show many uncommon features, like additional genes, high
rates of gene rearrangement, high AT content. Moreover, Doubly Uniparental Inheritance …

More than 100 species of bivalve mollusks are currently known to carry two highly diverged
mitochondrial DNA (mtDNA) molecules, one of which is transmitted through the egg and the …
