“…minima had 22 putative tRNA genes, 2 rRNA genes (12S rRNA and 16S rRNA), 12 PCGs and one control region (CR) including an origin of the light-strand replication (OL) region. According to our statistics, all species of Adapedonta we downloaded contained the atp8 gene, except for species of the family Pharidae [ 45 , 47 – 51 ]. The gene arrangement of the mitogenome of S .…”

Siliqua minima (Gmelin, 1791) is an important economic shellfish species belonging to the family Pharidae. To date, the complete mitochondrial genome of only one species in this family (Sinonovacula constricta) has been sequenced. Research on the Pharidae family is very limited; to improve the evolution of this bivalve family, we sequenced the complete mitochondrial genome of S. minima by next-generation sequencing. The genome is 17,064 bp in length, consisting of 12 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), and two ribosomal RNA genes (rRNA). From the rearrangement analysis of bivalves, we found that the gene sequences of bivalves greatly variable among species, and with closer genetic relationship, the more consistent of the gene arrangement is higher among the species. Moreover, according to the gene arrangement of seven species from Adapedonta, we found that gene rearrangement among families is particularly obvious, while the gene order within families is relatively conservative. The phylogenetic analysis between species of the superorder Imparidentia using 12 conserved PCGs. The S. minima mitogenome was provided and will improve the phylogenetic resolution of Pharidae species.

“…And the content and structure of control regions are vastly different across the major molluscan lineages, with high rates of evolutionary turnover by novel tandem duplications, often of previously duplicated regions [20,38,51,73,90,91]; transpositions, especially of tRNAs, into this region [21,32,73,92,93]; and newly evolved simple sequence repeats such as poly(AT) tracts [94,95]. Together these primary sequence features share the ability to produce secondary structures including stem-loop [34,96], cloverleaf [56,84,97,98] and cruciform [89] structures in the control region, which in other organisms appear to be related to mtDNA replication and transcription [1,56].…”

“…This hypothesis is attractive because it would also help explain why control regions often feature pseudo-tRNAs (e.g. scallops, oysters and clams [32,73,93]) and other tRNA-like secondary structures [56,84,97,98,104]. Misincorporation of tRNAs might also contribute to the high rates of evolutionary turnover in the control region, as new tRNA incorporation events push older sequences out of the control region.…”

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 description’. However, a more broad phylogenetic sampling of complete animal mitochondrial genomes has found many cases where these features do not exist, and the phylum Mollusca is especially replete with these exceptions. The characterization of full mollusc mitogenomes required considerable effort involving challenging molecular biology, but has created an enormous catalogue of surprising deviations from that textbook description, including wide variation in size, radical genome rearrangements, gene duplications and losses, the introduction of novel genes, and a complex system of inheritance dubbed ‘doubly uniparental inheritance’. Here, we review the extraordinary variation in architecture, molecular functioning and intergenerational transmission of molluscan mitochondrial genomes. Such features represent a great potential for the discovery of biological history, processes and functions that are novel for animal mitochondrial genomes. This provides a model system for studying the evolution and the manifold roles that mitochondria play in organismal physiology, and many ways that the study of mitochondrial genomes are useful for phylogeny and population biology. This article is part of the Theo Murphy meeting issue ‘Molluscan genomics: broad insights and future directions for a neglected phylum’.
