  1. 1. Cyanobacteria in symbiosis with plants : Protein patterns and regulatory mechanisms

    Författare :Martin Ekman; Birgitta Bergman; Dave G. Adams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; symbiosis; Nostoc; Gunnera; Azolla; nitrogenase; modification; heterotrophic; proteomics; unsequenced; Plant physiology; Växtfysiologi;

    Sammanfattning : Cyanobacteria belonging to the heterocystous genus Nostoc, capable of oxygenic photosynthesis and nitrogen fixation via the enzyme nitrogenase, may form symbiotic associations with plants. In these associations most of the N2 fixed by the symbiotic cyanobacteria (cyanobiont) is transferred to the host, which in turn supplies the cyanobiont with fixed carbon. LÄS MER

  3. 2. The puzzle of lichen symbiosis : Pieces from Thamnolia

    Författare :Ioana Onuț-Brännström; Hanna Johannesson; Leif Tibell; Anne Pringle; Uppsala universitet; []
    Nyckelord :Thamnolia; lichen; symbiosis; photobiont; mycobiont; phylogeography; MAT-loci; barcoding; NGS; genome; transcriptome; Ice Age; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Symbiosis brought important evolutionary novelties to life on Earth. Lichens, the symbiotic entities formed by fungi, photosynthetic organisms and bacteria, represent an example of a successful adaptation in surviving hostile environments. Yet many aspects of the lichen symbiosis remain unexplored. LÄS MER

  4. 3. Cyanobacteria in symbiosis with boreal forest feathermosses : from genome evolution and gene regulation to impact on the ecosystem

    Författare :Denis Warshan; Ulla Rasmussen; Elke Dittmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Feathermosses; Symbiosis; Boreal forest; Gene flow; Proteogenomic; Transcriptomic; Community structure and composition; Dinitrogen fixation; Plant Physiology; växtfysiologi;

    Sammanfattning : Among dinitrogen (N2)-fixing some cyanobacteria can establish symbiosis with a broad range of host plants from all plant lineages including bryophytes, ferns, gymnosperms, and angiosperms. In the boreal forests, the symbiosis between epiphytic cyanobacteria and feathermosses Hylocomium splendens and Pleurozium schreberi is ecologically important. LÄS MER

  5. 4. Nostoc-cycad symbiosis : with emphasis on the cyanobiont

    Författare :Peter Lindblad; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

  7. 5. 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
