Data from: Two complete mitochondrial genomes from Praticolella mexicana Perez, 2011 (Polygyridae) and gene order evolution in Helicoidea (Mollusca, Gastropoda)
Helicoidea is a diverse group of globally distributed land snails. While much is known regardingthe relationships of helicoid taxa, comparatively little is known about the evolution of themitochondrial genome in the superfamily. We sequenced two complete mitochondrial genomesfrom Praticolella mexicana Perez, 2011 representing the first such data from the helicoid familyPolygyridae, and used them in an evolutionary analysis of mitogenomic gene order. We foundthe mitochondrial genome of P. mexicana to be 14,008 bp in size, possessing the typical 37metazoan genes. Multiple alternate stop codons are used, as are incomplete stop codons, andmitogenome size and nucleotide content is consistent with other helicoid species. Our analysis ofgene order suggested that Helicoidea has undergone five mitochondrial rearrangements in thepast. Four rearrangements were limited to tRNA genes, including one homoplasticrearrangement in Helicidae and (Bradybaenidae+Camaena+P. mexicana). The fifthrearrangement, unique to Aegista, involved a protein coding gene.
Data from: Rapid evolution of cheating mitochondrial genomes in small yeast populations
Outcrossed sex exposes genes to competition with their homologues, allowing alleles that transmit more often than their competitors to spread despite organismal fitness costs. Mitochondrial populations in species with biparental inheritance are thought to be especially susceptible to such cheaters because they lack strict transmission rules like meiosis or maternal inheritance. Yet the interaction between mutation and natural selection in the evolution of cheating mitochondrial genomes has not been tested experimentally. Using yeast experimental populations, we show that although cheaters were rare in a large sample of spontaneous respiratory-deficient mitochondrial mutations (petites), cheaters evolve under experimentally enforced outcrossing even when mutation supply and selection are restricted by repeatedly bottlenecking populations.
Data from: Mitochondrial phylogeny of notothenioids: a molecular approach to Antarctic fish evolution and biogeography
Antarctic waters represent a unique marine environment delimited by an oceanographic barrier, the Polar Front Zone, and characterized by constant subzero temperatures and presence of sea ice. A group of teleost fish, the Notothenioidei, have adapted to these challenging environmental conditions, undergoing a remarkable diversification. In the present study a total of 798 base pairs, generated from partial sequencing of 16S and 12S mitochondrial ribosomal RNA genes, were examined in 33 notothenioid species representative of all families included in the suborder Notothenioidei. Phylogenetic trees, reconstructed on the basis of sequence data using different methods, indicate that traditional hypotheses on notothenioid systematics and biogeography might be in need of reexamination. Molecular evidence suggests that vicariant speciation could be invoked to explain the early divergence of Eleginops maclovinus, a species previously included in the family Nototheniidae, which is now proposed as the closest sister group to all the rest of notothenioids apart from bovichtids. On the other hand, repeated, independent dispersal through the Polar Front is proposed for the divergence of other subantarctic notothenioid species. Likewise, multiple, independent transitions from benthic to pelagic habit are inferred from molecular data, at variance with the more conservative hypothesis based on cladograms reconstructed from morphological data.
