  1. 1. Exploring the diversity and evolution of giant viruses in deep sea sediments using genome-resolved metagenomics

    Författare :Disa Bäckström; Thijs J. G. Ettema; Anna J. Szekely; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metagenomics; binning; viruses; NCLDV; Megavirales; viral evolution.;

    Sammanfattning : Viruses are the most abundant biological entities on this planet, which is impressive considering that they are completely dependent on their hosts for reproduction. Recently the idea of what viruses are has changed dramatically, with the discovery of giant viruses that belong to the Nucleocytoplasmic Large DNA Viruses (NCLDV), such as Mimiviridae, Marseilleviridae, and the proposed families Pandoraviruses, and Pithoviruses.

  3. 2. Genomic and evolutionary exploration of Asgard archaea

    Författare :Eva F. Caceres; Thijs J. G. Ettema; Simonetta Gribaldo; Uppsala universitet; []
    Nyckelord :archaea; Asgard; eukaryogenesis; metagenomics; genome binning; phylogenetics; phylogenomics; comparative genomics; gene tree-species tree reconciliation; ancestral reconstruction; long-read metagenomics;

    Sammanfattning : Current evolutionary theories postulate that eukaryotes emerged from the symbiosis of an archaeal host with, at least, one bacterial symbiont. However, our limited grasp of microbial diversity hampers insights into the features of the prokaryotic ancestors of eukaryotes. LÄS MER

  4. 3. Bioinformatic Methods in Metagenomics

    Sammanfattning : Microbial organisms are a vital part of our global ecosystem. Yet, our knowledge of them is still lacking. Direct sequencing of microbial communities, i.e. LÄS MER

  5. 4. Structure and function of microbial communities in acid sulfate soil and the terrestrial deep biosphere

    Författare :Xiaofen Wu; Mark Dopson; Ricardo Amils; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular phylogeny; acid sulfate soils; metal; acidophiles; deep biosphere; oligotrophy; biofilm formation; metagenome; binning; metabolism; Mikrobiologi; Microbiology;

    Sammanfattning : This thesis describes the use of different DNA sequencing technologies to investigate the structure and function of microbial communities in two extreme environments, boreal acid sulfate soil and the terrestrial deep biosphere.The first of the two investigated environments was soils containing un-oxidized metal sulfides that are termed ‘potential acid sulfate soil’ (PASS) materials.

  7. 5. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

    Författare :Joran Martijn; Thijs J.G. Ettema; Andrew Roger; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
