  2. 1. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

    Author : Joran Martijn; Thijs J.G. Ettema; Andrew Roger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cultivation independent genomics; metagenomics; single-cell genomics; metagenomic binning; phylogenetics; phylogenomics; phylogenetic artefacts; comparative genomics; gene tree-species tree reconciliation; rRNA amplicon sequencing; Tara Oceans; origin of mitochondria; Alphaproteobacteria; Rickettsiales; Haloarchaea; endosymbiosis; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. READ MORE

  4. 2. Evolutionary transitions across the tree of life : Phylogenomic case studies in environmental archaea, bacteria and eukaryotes

    Author : Max Emil Schön; Thijs J. G. Ettema; Fabien Burki; David Moreira; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary transitions; environmental sequencing; metagenomics; single-cell genomics; phylogenomics; haloarchaea; Hikarchaeia; Rickettsiales; Picozoa; plastid evolution; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Microbes form the majority of life on Earth, but have been systematically underrepresented in historical research. The sequencing revolutions of the last two decades have completely changed the way we can study microbial genomic information, giving us the means to probe ever deeper into their evolution.

  5. 3. Inferring Ancestry : Mitochondrial Origins and Other Deep Branches in the Eukaryote Tree of Life

    Author : Ding He; Sandra Baldauf; Siv Andersson; Andrew Roger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Phylogeny; Phylogenomics; Mitochondria; Eukaryote tree of life; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. READ MORE

  6. 4. Phylogenomics of Oceanic Bacteria

    Author : Johan Viklund; Siv Andersson; Edward DeLong; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phylogenetics; SAR11; mitochondria;

    Abstract : The focus of this thesis has been the phylogenomics and evolution of the Alphaproteobacteria. This is a very diverse group which encompasses bacteria from intraceullar parasites, such as the Rickettsiales, to freeliving bacteria such as the most abundant bacteria on earth, the SAR11. READ MORE
