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. Biosynthetic and synthetic studies of the fungal metabolite galiellalactone

   Författare :Martin H Johansson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknik; Organisk kemi; Organic chemistry; enzyme; mycelium; intramolecular Diels-Alder reaction; Diels-Alderase; asymmetric synthesis; biosynthesis; total synthesis; STAT3 inhibition; galiellalactone; fungal metabolite;

   Sammanfattning : Galiellalactone is a fungal metabolite found in the basidiomycetes Galiella rufa and the unidentified strain A111-95. It has been shown to possess promising activities as an inhibitor of the IL-6 mediated STAT3 signaling in HepG2 cells. LÄS MER

4. 3. The external mycorrhizal mycelium - growth and interactions with saprophytic microorganisms

   Författare :Pål Axel Olsson; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacteriology; Microbiology; Fatty acids; Mycorrhiza; Bacteria; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : The interactions between external mycorrhizal mycelia and saprophytic microorganisms were studied in experiments with growth chambers specially designed to enable the mycelia to develop in root-free soil compartments. The growth of the mycorrhizal mycelia was estimated by use of biochemical signature compounds. LÄS MER

5. 4. Ectomycorrhizal fungi: Their role in nitrogen retention and carbon sequestration in northern coniferous forests

   Författare :Adam Bahr; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ectomycorrhizal fungi; Carbon sequestration; Nitrogen deposition; Nitrogen leakage; Field survey; Boreo-nemoral forest; Boreal Forest; Ergosterol; Free ergosterol; Mesh-bags; Multivariate analysis;

   Sammanfattning : Almost all northern forest tree species live in symbioses with ectomycorrhizal fungi (EMF). The trees allocate up to half of the photoassimilated carbon (C) through the roots to EMF. In return EMF deliver nutrients from both inorganic and organic sources in the soil, as well as water.

7. 5. Transcriptome Analyses of the Nematode-trapping Fungus Monacrosporium haptotylum

   Författare :Margareta Tholander; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Microbiology; bacteriology; virology; mycology; Pathogenic fungi; Nematophagous fungi; Nematodes; Biological control; cDNA microarray; Transcriptome analysis; Nematode-trapping fungi; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Nematode-trapping fungi are soil living organisms with the ability to infect and kill nematodes. These fungi have developed specialized infection structures, traps for the capture of nematodes. To be able to identify genes in nematode-trapping fungi that are involved in the infection of nematodes cDNA microarrays were constructed. LÄS MER
