  1. 1. The Ecophysiology of Arbuscular Mycorrhizal Fungi: Phosphatase Activity Associated with Extraradical and Intraradical Mycelium

    Författare :Ingrid van Aarle; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Scutellospora; polyphosphate; phosphorus uptake; phosphorus transfer; phosphatase; pH; mycelium; Glomus; fatty acid; Gigaspora; arbuscular mycorrhiza; ELF;

    Sammanfattning : Arbuscular mycorrhizal (AM) fungi colonise a wide range of plant species and are especially common in soils with a relatively high pH, where phosphorus availability is a limiting factor for primary production. The aim of this thesis was to study the ecophysiology of arbuscular mycorrhizal (AM) fungi when exposed to different environments. 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
