  1. 1. Evolution of symbiotic lineages and the origin of new traits

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Daniel Tamarit; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; symbiosis; host-association; Lactobacillus; Bifidobacterium; Rhizobiales; Bartonella; honeybees; ants; codon usage bias; genome architecture; genome organization; gene transfer agent; evolutionary genomics; comparative genomics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : This thesis focuses on the genomic study of symbionts of two different groups of hymenopterans: bees and ants. Both groups of insects have major ecological impact, and investigating their microbiomes increases our understanding of their health, diversity and evolution. READ MORE

  2. 2. Evolution of cellular complexity and other remarkable features in Gemmataceae Complex bacterial lineages defy prokaryotic trends

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mayank Mahajan; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; Planctomycetes; Gemmataceae; functional organization; signalling; protein interaction; peptidoglycan; membranes; cell division; radiation tolerance; Pfam; SCOP; comparative genomics; protein architecture; domain shuffling and orthologous clustering; Bioinformatics; Bioinformatik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : Bacteria of the family Gemmataceae belong the phylum Planctomycetes and are remarkable because of their complex cellular architectures, previously considered to be traits exclusive to eukaryotes. This thesis provides clues to the atypical cell envelope, the enhanced radiotolerance and the amazing cellular complexity of these bacteria. READ MORE

  3. 3. Surviving the ratchet Modelling deleterious mutations in asexual populations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Söderberg; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical biology; Population genetics; Stochastic modelling; Genome evolution; Muller s Ratchet; NATURAL SCIENCES Biology Cell and molecular biology Genetics; NATURVETENSKAP Biologi Cell- och molekylärbiologi Genetik; NATURAL SCIENCES Biology Organism biology; NATURVETENSKAP Biologi Organismbiologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : One of the most unforgiving processes in nature is that of Muller's ratchet, a seemingly irreversible accumulation of deleterious mutations that all organisms have to deal with or face extinction. The most obvious way to avoid fitness collapse is recombination, though asexual populations usually do not have the luxury of recombining freely. READ MORE

  4. 4. Mine the Gaps Evolution of Eukaryotic Protein Indels and their Application for Testing Deep Phylogeny

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pravech Ajawatanawong; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; indel; insertion deletion; protein evolution; bioinformatics; non-bilateria; eukaryotes; phylogeny; Biologi med inriktning mot systematik; Biology with specialization in Systematics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Insertions/deletions (indels) are potentially powerful evolutionary markers, but little is known about their evolution and few tools exist to effectively study them. To address this, I developed SeqFIRE, a tool for automated identification and extraction of indels from protein multiple sequence alignments. READ MORE

  5. 5. Hidden Diversity Revealed Genomic, Transcriptomic and Functional Studies of Diplomonads

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Giardia intestinalis; Spironucleus salmonicida; Spironucleus barkhanus; intestinal parasite; hydrogenosome; mitosome; lateral gene transfer; horizontal gene transfer; diplomonad; metamonad; sexual recombination; transfection; protein complex purification; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : The diplomonads are a diverse group of eukaryotic microbes found in oxygen limited environments such as the intestine of animals were they may cause severe disease. Among them, the prominent human parasite Giardia intestinalis non-invasively colonizes the small intestine of humans and animals where it induces the gastrointestinal disease giardiasis. READ MORE
