Abstract: Clausiliidae snails have been of great interest to conchologists for their unique clausilium structure and rich species diversity. We described the complete mitochondrial genome of Euphaedusa planostriata (Heude, 1882). The mitogenome is 15,041bp in length, with a total of 37 genes, including 13 proteincoding genes, 2 rRNA genes, and 22 tRNA genes. It is consistent with the basic characteristics of the known stylommatophoran mitochondrial genome. Phylogenetic analysis using mitogenomes showed that Euphaedusa p… Show more

The family Clausiliidae was proposed as a model for studying the diversity of breeding biology in land snails. This study assembled a nearly complete mitogenome (15,417 bp) for the clausiliid snail Euphaedusa aculus . The mitogenome includes 13 protein-coding genes (PCGs), two ribosomal RNAs, and 22 transfer RNAs, with a gene order consistent with other clausiliids. Most PCGs use ATN start codons and complete stop codons, except for atp6, nad4 , and nad5 , which start with TTG, and atp6, cox3 , and nad3 , which have incomplete stop codons. Phylogenetic analyses revealed that E. aculus is closely related to E. planostriata . This mitogenome provides a valuable molecular resource for future evolutionary research on land snails.

Molluscan mitochondrial genomes are unusual because they show wide variation in size, radical genome rearrangements and frequently show high variation (> 10%) within species. As progress in understanding this variation has been limited, we used whole genome sequencing of a six-generation matriline of the terrestrial snail Cepaea nemoralis, as well as whole genome sequences from wild-collected C. nemoralis, the sister species C. hortensis, and multiple other snail species to explore the origins of mitochondrial DNA (mtDNA) variation. The main finding is that a high rate of SNP heteroplasmy in somatic tissue was negatively correlated with mtDNA copy number in both Cepaea species. In individuals with under ten mtDNA copies per nuclear genome, more than 10% of all positions were heteroplasmic, with evidence for transmission of this heteroplasmy through the germline. Further analyses showed evidence for purifying selection acting on non-synonymous mutations, even at low frequency of the rare allele, especially in cytochrome oxidase subunit 1 and cytochrome b. The mtDNA of some individuals of Cepaea nemoralis contained a length heteroplasmy, including up to 12 direct repeat copies of tRNA-Val, with 24 copies in another snail, Candidula rugosiuscula, and repeats of tRNA-Thr in C. hortensis. These repeats likely arise due to error prone replication but are not correlated with mitochondrial copy number in C. nemoralis. Overall, the findings provide key insights into mechanisms of replication, mutation and evolution in molluscan mtDNA, and so will inform wider studies on the biology and evolution of mtDNA across animal phyla.
