“…While many studies examine mitochondrial gene order in the context of sequence phylogenies (e.g. Aguileta et al 2014, Weigert et al 2016), we found no studies that used MLGO or similar older programs (e.g. MGRA, Alekseyev and Pevzner 2009) to generate mitochondrial gene order phylogenies.…”

“…Mitogenome organization has several qualities that make it a valuable phylogenetic marker. For example, mitochondrial gene order and content can be highly variable in metazoans (Black and Roehrdanz 1998, Mindell et al 1998, Weigert et al 2016). Transposition of tRNA genes is more common than movement of protein coding or ribosomal RNA genes (Xu et al 2006) and may be weighted accordingly during analysis (Bader et al 2008).…”

Helicoidea is a diverse group of land snails with a global distribution. While much is known regarding the relationships of helicoid taxa, comparatively little is known about the evolution of the mitochondrial genome in the superfamily. We sequenced two complete mitochondrial genomes from Praticolella mexicana Perez, 2011 representing the first such data from the helicoid family Polygyridae, and used them in an evolutionary analysis of mitogenomic gene order. We found the mitochondrial genome of Praticolella mexicana to be 14,008 bp in size, possessing the typical 37 metazoan genes. Multiple alternate stop codons are used, as are incomplete stop codons. Mitogenome size and nucleotide content is consistent with other helicoid species. Our analysis of gene order suggested that Helicoidea has undergone four mitochondrial rearrangements in the past. Two rearrangements were limited to tRNA genes only, and two involved protein coding genes.

“…Annelids, like other bilaterians, typically have 37 mitochondrial genes 18–20 . Recent descriptions of mitochondrial genomes from several annelid linneages revealed marked differences in gene order that are helping to resolve phylogenetic relationships, even though some inconsistencies between sequence data and phylogenies remain 14, 20, 21 . There are currently about 90 complete annelid mitochondrial DNA sequences (mtDNA) published 14, 22 , with many underrepresented linneages, making broad scale mitogenomic comparisons limited given the extremely high number of species in the deep-sea 13 .…”

Wood falls provide episodic fluxes of energy to the sea floor that are degraded by a species-rich benthic fauna. Part of this rich diversity includes annelid polychaetes but unfortunately, our understanding of such fauna is limited and their genetic variability and evolutionary origins remain poorly known. In this study, we sequenced complete mitochondrial genomes from three congeneric Decemunciger (Ampharetidae) individuals that had colonized multiple wood falls in the deep (~1600 m) NE Pacific Ocean. Mitochondrial gene order within Decemunciger was similar to the three other available Terebellomorpha genomes, consistent with the relatively conserved nature of mitochondrial genomes within annelids. Unexpectedly, we found introns within the cox1, nad1 and nad4 genes of all three genomes assembled. This is the greatest number of introns observed in annelid mtDNA genomes, and possibly in bilaterians. Interestingly, the introns were of variable sizes suggesting possible evolutionary differences in the age and origins of introns. The sequence of the introns within cox1 is similar to Group II introns previously identified, suggesting that introns in the mitochondrial genome of annelids may be more widespread then realized. Phylogenetically, Decemunciger appears to be a sister clade among current vent and seep deep-sea Ampharetinae.
