  1. 1. Mitochondrial Evolution : Turning Bugs into Features

    Author : Olof Karlberg; Siv Andersson; Michael Gray; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Biology; Biologi; Biology; Biologi;

    Abstract : The bacterial origin of mitochondria from an ancient endosymbiosis is now widely accepted and the mitochondrial ancestor is generally believed to belong to the bacterial subdivision α-proteobacteria. The high fraction of mitochondrial proteins encoded in the nucleus has commonly been explained with a massive transfer of genes from the genome of the ancestral mitochondrion. READ MORE

  2. 2. Phylogeny of Artiodactyla and Cetacea - based on mitochondrial genomes

    Author : Björn M Ursing; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Genetics; mitochondrial genome; phylogeny; Artiodactyla; Cetacea; cytogenetics; Genetik; cytogenetik;

    Abstract : Artiodactyla (eved-toed ungulates) and Cetacea (whales) are two mammalian orders that are commonly recognised as sistergroups. Recently it has been suggested that Cetacea originated within Artiodactyla, but the relationships among the different artiodactyl lineages and Cetacea have not been conclusively established.

  3. 3. Mitochondrial and Eukaryotic Origins : A Phylogenetic Perspective

    Author : Björn Brindefalk; Siv Andersson; James McInerney; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; Phylogenetics; Mitochondrial origin and Evolution; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Mitochondria are eukaryotic cellular organelles responsible for power-generation, believed to have come into existence by an endo-symbiontic event where a bacterial cell was incorporated by an un-specified "proto-eukaryote". Phylogenetic analysis have shown that the mitochondrial ancestor was most related to present-day alpha-proteobacteria, although the exact nature of the mitochondrial progenitor remains disputed.

  4. 4. A new perspective on avian phylogeny - a study based on mitochondrial genomes

    Author : Anna Bartosch-Härlid; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Genetics; thyroid; neoteni; mitochondrial DNA; phylogeny; Class Aves; Palaeognathae; cytogenetics; Genetik; cytogenetik;

    Abstract : The Class Aves (birds) is generally divided into two main groups - the Palaeognathae and the Neognathae. Paleognathous birds are the flightless ratites and the tinamous, while Neognathae include all other extant birds (more than 9,000 species). READ MORE

  5. 5. Methods for Analyzing Genomes

    Author : Patrik L. Ståhl; Joakim Lundeberg; Ivo Gut; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; array; sequence capture; genotyping; trinucleotide threading; sequencing; massively parallel sequencing; single molecule sequencing; Visual DNA; p53; single nucleotide polymorphism; biomarker; Genetics; Genetik;

    Abstract : The human genome reference sequence has given us a two‐dimensional blueprint of our inherited code of life, but we need to employ modern‐day technology to expand our knowledge into a third dimension. Inter‐individual and intra‐individual variation has been shown to be larger than anticipated, and the mode of genetic regulation more complex. READ MORE
