Lophotrochozoan mitochondrial genomes.
Progress in both molecular techniques and phylogenetic methods has challenged many of the interpretations of traditional taxonomy. One example is in the recognition of the animal superphylum Lophotrochozoa (annelids, mollusks, echiurans, platyhelminthes, brachiopods, and other phyla), although the relationships within this group and the inclusion of some phyla remain uncertain. While much of th...
متن کاملMitochondrial genomes: anything goes.
Mitochondria have their own genetic system – a vestigial genome originating from an endosymbiotic a-proteobacterial ancestor. The genetic function of mitochondrial DNA (mtDNA) is well-conserved, being involved in a maximum of five mitochondrial processes: invariantly in respiration and/or oxidative phosphorylation and translation, and also in transcription, RNA maturation and protein import. Re...
متن کاملAngiosperm mitochondrial genomes and mutations.
Flowering plants harbor the largest mitochondrial genomes reported so far. At present, the nucleotide sequences of 15 mitochondrial genomes from seven angiosperm species are available, making detailed comparative analysis feasible. The gene content is variable among the species, but the most striking feature is the fluidity of intergenic regions, where species-specific sequences predominate. Ad...
متن کاملThe Mitochondrial DNA Polymerase Promotes Elimination of Paternal Mitochondrial Genomes
Mitochondrial DNA (mtDNA) is typically inherited from only one parent [1-3]. In animals, this is usually the mother. Maternal inheritance is often presented as the passive outcome of the difference in cytoplasmic content of egg and sperm; however, active programs enforce uniparental inheritance at two levels, eliminating paternal mitochondrial genomes or destroying mitochondria delivered to the...
متن کاملBird mitochondrial gene order: insight from 3 warbler mitochondrial genomes.
Two main gene orders exist in birds: the ancestral gene order and the remnant control region (CR) 2 gene order. These gene orders differ by the presence of 1 or 2 copies of the CR, respectively. Among songbirds, Oscines were thought to follow the ancestral gene order, with the exception of the lyrebird and Phylloscopus warblers. Here, we determined the complete mitochondrial genome sequence of ...
