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

    Author : Axel Künstner; Hans Ellegren; Hanna Johannesson; Chris Ponting; Uppsala universitet; []
    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

  4. 7. Comparative Genomics in Birds

    Author : Erik Axelsson; Hans Ellegren; Martin Lercher; Uppsala universitet; []
    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

  5. 8. Evolutionary Genomics of Nematode-Trapping Fungi

    Author : Tejashwari Meerupati; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nematode-trapping fungi; Comparative Genomics; Comparative Transcriptomics; Differential gene expression; Gene duplication; Parasitism; Protein family expansion.;

    Abstract : Nematode-trapping fungi are ubiquitous, soil-living organisms with the ability to infect and kill nematodes. These fungi have developed specialized infection structures for the capture of nematodes. READ MORE

  6. 9. Evolutionary genomics of symbiotic fungi

    Author : Balaji Rajashekar; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein family; Symbiosis; Paxillus involutus; Laccaria bicolor; Hydrophobin; Fungi; Ectomycorrhizae; Evolution; Comparative Genomics; Basidiomycetes;

    Abstract : Ectomycorrhizae is a mutualistic association between roots of woody plants and a diverse range of soil fungi. The fungi exchange soil derived mineral nutrients for photosynthetic sugars from the host plant. The mycorrhizal symbioses are commonly found in all forest ecosystems and have a major ecological and economical importance. READ MORE

  7. 10. Genome Evolution and Niche Differentiation of Bacterial Endosymbionts

    Author : Kirsten Maren Ellegaard; Siv Andersson; Andrés Moya; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; niche; habitat; endosymbiont; gut microbiome; honey bee; Wolbachia; comparative; genomics;

    Abstract : Most animals contain chronic microbial infections that inflict no harm on their hosts. Recently, the gut microflora of humans and other animals have been characterized. However, little is known about the forces that shape the diversity of these bacterial communities. READ MORE
