Mitochondrial DNA sequences, often in combination with nuclear markers and morphological data, are frequently used to unravel the phylogenetic relationships, population dynamics and biogeographic histories of a plethora of organisms. The information provided by examining complete mitochondrial genomes also enables investigation of other evolutionary events such as gene rearrangements, gene dupl...

The nuclear gene from Saccharomyces cerevisiae that encodes the major mitochondrial nuclease was cloned. Gene sequences were identified from a lambda gt11 library by antibodies specific to the mitochondrial nuclease. DNA from the phage recombinant was used to isolate the entire nuclease gene from a plasmid library. Yeast strains containing the nuclease gene on a multicopy plasmid vector overpro...

Abstract Mitochondria contain an organellar genome that encodes for subunits of the respiratory chain. Its coordinated expression is essential eukaryotic life and defects in this process lead to severe disease. However, molecular mechanisms underlying mitochondrial gene remain poorly understood. Recent structural functional studies have provided first mechanistic insights into highlight evoluti...

Two species of newts the genus Triturus are known to occur in Türkiye: ivanbureschi Wielstra & Arntzen, 2013 and T. anatolicus 2016. Here, we used mitochondrial ND4 gene as a genetic marker determine taxonomic position new population found Posof, Ardahan, northeastern Anatolia. It was shown belongs karelinii (Strauch, 1870), which is thus third present Türkiye.

We use full mitochondrial genomes to test the robustness of the phylogeny of the Octocorallia, to determine the evolutionary pathway for the five known mitochondrial gene rearrangements in octocorals, and to test the suitability of using mitochondrial genomes for higher taxonomic-level phylogenetic reconstructions. Our phylogeny supports three major divisions within the Octocorallia and show th...

Editing is a general event in plant mitochondrial messenger RNAs, but has never been detected in a plant mitochondrial transfer RNA (tRNA). We demonstrate here the occurrence of a tRNA editing event in higher plant mitochondria: in both bean and potato, the C encoded at position 4 in the mitochondrial tRNA(Phe)(GAA) gene is converted into a U in the mature tRNA. This nucleotide change corrects ...
