Over the last three decades, mitochondrial DNA has been the most popular marker of molecular diversity, for a combination of technical ease-of-use considerations, and supposed biological and evolutionary properties of clonality, near-neutrality and clock-like nature of its substitution rate. Reviewing recent literature on the subject, we argue that mitochondrial DNA is not always clonal, far fr...
A new type of maize mitochondrial genome has been identified in the male fertile (normal) inbred line A188. It has been named NA (N in the A188 nuclear background). In comparison to previously described maize mitochondrial genomes, it is classified as a new type since the genome contains unique DNA sequences and unique sets of repeated sequences, and has a unique organization. This brings the n...
We report the complete mitochondrial genome sequence of Lichtheimia ramosa (syn. Lichtheimia hongkongensis), the first complete mitochondrial DNA sequence of the genus Lichtheimia. This 31.8-kb mitochondrial genome encodes 11 subunits of respiratory chain complexes, 3 ATP synthase subunits, 25 tRNAs, and small and large rRNAs, with the gene order atp9-cox2-atp6-cox3-cox1-nad2-nad3-cob-nad1-nad6...
BACKGROUND We re-assess support for our three stage model for the peopling of the Americas in light of a recent report that identified nine non-Native American mitochondrial genome sequences that should not have been included in our initial analysis. Removal of these sequences results in the elimination of an early (i.e. approximately 40,000 years ago) expansion signal we had proposed for the p...
Even though mitochondrial genomes, which characterize eukaryotic cells, were first discovered more than 50 years ago, mitochondrial genomics remains an important topic in molecular biology and genome sciences. The Phylum Alveolata comprises three major groups (ciliates, apicomplexans, and dinoflagellates), the mitochondrial genomes of which have diverged widely. Even though the gene content of ...
As a part of our initiative aimed at a large-scale comparative analysis of fungal mitochondrial genomes, we determined the complete DNA sequence of the mitochondrial genome of the yeast Candida subhashii and found that it exhibits a number of peculiar features. First, the mitochondrial genome is represented by linear dsDNA molecules of uniform length (29 795 bp), with an unusually high content ...
The genetic code is no longer universal, even in non-mitochondrial genomes. Recent studies have implicated the eukaryotic release factor eRF1 in mediating coding changes that are not as inconceivable as once thought. Specific residues in eRF1 proteins can be correlated with specific code changes in a wide variety of taxa.
The data in this paper are related to the research article entitled "Taxonomic status and phylogenetic relationship of tits based on mitogenomes and nuclear segments" (X.J. Li et al., 2016) [1]. The mitochondrial genomes and nuclear segments of tits were sequenced to analyze mitochondrial characteristics and phylogeny. In the data, the analyzed results are presented. The data holds the resultin...
Mitochondrial DNA (mtDNA) lineages of macro-haplogroup L (excluding the derived L3 branches M and N) represent the majority of the typical sub-Saharan mtDNA variability. In Europe, these mtDNAs account for <1% of the total but, when analyzed at the level of control region, they show no signals of having evolved within the European continent, an observation that is compatible with a recent arriv...
