  1. 1. 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

  3. 2. Evolutionary genomics of symbiotic fungi

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

    Sammanfattning : 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. LÄS MER

  4. 3. Effects of nitrogen deposition on the growth, metabolism and activity of ectomycorrhizal fungi

    Författare :Magnus Ellström; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nitrogen deposition; Ectomycorrhizal fungi; Symbiosis; SOM modification; Carbon starvation; Metabolism; Nitrogen leakage; IR-spectroscopy; Mesh bags; Microarray; Axenic growth; Transcriptomics.;

    Sammanfattning : Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. LÄS MER

  5. 4. Genome Evolution in Maternally Inherited Insect Endosymbionts

    Författare :Lisa Klasson; Siv Andersson; Jonas Sandström; George Weinstock; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Biology; Biologi;

    Sammanfattning : Symbiosis is a widely common phenomenon in nature and has undoubtedly contributed to the evolution of all organisms on earth. Symbiotic associations can be of varying character, such as parasitic or mutualistic, but all imply a close relationship. LÄS MER
