  1. 1. Cantharellus cibarius : mycorrhiza formation and ecology

    Författare :Eric Danell; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : .... LÄS MER

  3. 2. Signalling between plants and microorganisms

    Författare :Ulrika Troedsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; symbiosis; Chitinase; rhizobium; mycorrhiza; plant; glucanase; Biology; Biologi;

    Sammanfattning : Plants and microbes can interact in several ways. Plants can be attacked by different types of pathogens like fungi, virus and bacteria, but can also form symbioses with fungi and bacteria. Certain common antimicrobial proteins are produced by the plants regardless of the type of microbial interaction with the plant. LÄS MER

  4. 3. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field

    Författare :Zsofia Réka Stangl; Vaughan Hurry; Lisa Ainsworth; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

    Sammanfattning : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. LÄS MER

  5. 4. Trophic interactions in the tundra: Impacts of large mammal herbivory on carbon processes and fungal communities

    Författare :Cole Brachmann; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Herbivory; Arctic; Fungi; Trace gas fluxes; Decomposition; Biogenic Volatile Organic Compounds; Mycorrhiza; Tundra; Reindeer;

    Sammanfattning : Plant productivity is generally increasing in the Arctic as a consequence of accelerated climate change. The change in plant communities may coincide with a loss of carbon from Arctic soils due to increased decomposition and respiration. LÄS MER

  7. 5. External Mycelia of Mycorrhizal Fungi - responses to elevated N in forest ecosystems

    Författare :Lars Ola Nilsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ericoid; arbuscular; mycorrhiza; nitrogen; deposition; fertilisation; nitrate leaching; retention; field; forest; Quercus; deciduous; Plant ecology; Växtekologi; mykologi; virologi; bakteriologi; mycology; Microbiology; External mycelia; ectomycorrhiza; Mikrobiologi; bacteriology; virology;

    Sammanfattning : Most plants live in symbiosis with mycorrhizal fungi. Mycorrhizal roots constitute the interface between the plant and the soil, and almost every fine root of forest trees in nitrogen-limited boreal and temperate forests is colonised by ectomycorrhizal (EM) fungi. LÄS MER
