  2. 1. Comparative Genomics in Diplomonads Lifestyle Variations Revealed at Genetic Level

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Feifei Xu; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; comparative genomics; Giardia intestinalis; Spironucleus salmonicida; Trepomonas; diplomonad; intestinal parasite; free-living; sexual recombination; hydrogenosome; horizontal gene transfer; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : As sequencing technologies advance genome studies are becoming a basic tool for studying an organism, and with more genomes available comparative genomics is maturing into a powerful tool for biological research. This thesis demonstrates the strength of a comparative genomics approach on a group of understudied eukaryotes, the diplomonads. READ MORE

  4. 2. Speciation genomics A perspective from vertebrate systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nagarjun Vijay; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolution; speciation; genomics; vertebrate; adaptation; selection; linked selection; crow; killer whale; hybrid zone; transcriptomics; population genetics; behaviour; colouration; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Species are vital entities in biology. Species are generally considered to be discrete entities, consisting of a group of (usually interbreeding) individuals that are similar in phenotype and genetic composition, yet differ in significant ways from other species. READ MORE

  5. 3. Comparative Genomics of Endosymbiotic Bacteria

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ivica Tamas; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; comparative genomics; endosymbiotic bacteria; Buchnera; reductive evolution; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Genomes of intracellular bacteria are thought to be the products of reductive evolution. They have evolved from ancestral genomes of free-living bacteria through a process of massive gene loss. READ MORE

  6. 4. Birds as a Model for Comparative Genomic Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Axel Künstner; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Birds; Selection; Gene expression; Sequence evolution; Next-generation sequencing; Comparative genomics; Molecular evolution; Genomics; Substitution Rates; Non-coding DNA; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Comparative genomics provides a tool to investigate large biological datasets, i.e. genomic datasets. In my thesis I focused on inferring patterns of selection in coding and non-coding regions of avian genomes. READ MORE

  7. 5. Comparative Genomics in Birds

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Axelsson; Uppsala universitet.; [2007]
    Keywords : Molecular genetics; Birds; molecular evolution; macrochromosomes; microchromosomes; mutation rate; substitution rate; base composition; positive selection; genetic drift; population size; Genetik;

    Abstract : To shed light on forces that shape the molecular evolution of bird genomes, and in turn avian adaptations, comparative analyses of avian DNA sequences are important. Moreover, contrasting findings in birds to those of other organisms will lend a clearer view on general aspects of molecular evolution. READ MORE
