  1. 36. Symbiosis in Arbuscular Mycorrhizal Fungi : Unearthing genomic signatures

    Författare :Shadi Eshghi Sahraei; Anna Rosling; Vasilis Kokkoris; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; arbuscular mycorrhizal fungi; mutualistic symbiosis; soil microeukaryotic communities; phylogenomics; single spore assembly; gene family evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Arbuscular mycorrhizal (AM) fungi have been on earth since 470 million years ago. AM fungi form mutualistic symbiosis with most terrestrial plants and thus, are thought to have played important roles in land colonization together with plants. LÄS MER

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

    Författare :Feifei Xu; Jan O. Andersson; Staffan G. Svärd; Matt Berriman; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 38. Inference of Hierarchical Structure in Complex Systems

    Författare :Olof Görnerup; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein evolution; Substitution groups; Modularity; Hierarchical dynamics; RNA world; Genetic code; Aggregation; Primordial evolution; Molecular evolution; Model reduction; Self-organization; Lumping; Emergence; Coarse graining;

    Sammanfattning : Hierarchical organization is a central property of complex systems. It is even argued that a system is required to be hierarchical in order to evolve complexity within reasonable time. A hierarchy of a system is defined as the set of self-contained levels at which the system operates and can be described on. LÄS MER

  4. 39. The Role of Lhx2 During Organogenesis : - Analysis of the Hepatic, Hematopoietic and Olfactory Systems

    Författare :Åsa Kolterud; Leif Carlsson; Stefan Thor; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; LIM-homeobox gene; Lhx2; fetal liver; hepatic stellate cells; hematopoietic stem cells; septum transversum; self-renewal; odorant receptor genes; olfactory epithelium; olfactory sensory neuron; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : During embryonic development a variety of tissues and organs such as the lung, eye, and kidney are being formed. The generation of functional organs is regulated by reciprocal cell-cell interactions. Via the secretion of soluble molecules one type of cells affect the fate of their neighboring cells. LÄS MER

  5. 40. Database and Visualization for Advanced Systems Biology

    Författare :Natapol Pornputtapong; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; omic data visualization system; data standardization; data integration; database system; database design;

    Sammanfattning : In the information age, there is plenty of information available publicly in the field of biology. Utilization of biological data is still slow and inefficient compared to the amount of data generated. This problem arise due to the specific characteristics of biological data, which are complex, dynamic and variable. LÄS MER
