  1. 11. Plant-associated soil communities : Patterns, drivers and aboveground consequences

    Författare :Pil Uthaug Rasmussen; Ayco J. M. Tack; Martijn Bezemer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aboveground-belowground interactions; arbuscular mycorrhiza; climate; dispersal; environmental drivers; fungi; genetic variation; nematodes; plant-herbivore interactions; soil communities; spatial patterns; ekologi och evolution; Ecology and Evolution;

    Sammanfattning : Soil contains a wealth of diversity – bacteria, fungi, nematodes, arthropods and earthworms are just some of the many organisms found belowground. These organisms play an important role in shaping the soil environment and they strongly influence plant fitness, diversity and community composition. LÄS MER

  3. 12. 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

  4. 13. Phosphorus : flows to swedish food chain, fertilizer value, effect on mycorrhiza and environmental Impact of Reuse

    Författare :Kersti Linderholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Phosphorus is an essential element for plants, animals and humans and is also a scarce resource as a raw material for fertilizer production. The flows of phosphorus to and from Swedish agriculture and food chain was investigated with a material flow analysis (MFA). LÄS MER

  5. 14. The actinorhizal symbiosis of Datisca glomerata: Search for nodule-specific marker genes

    Författare :Irina V. Demina; Katharina Pawlowski; Franziska Krajinski; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actinorhizal symbiosis; Datisca glomerata; nodule transcriptome; nodule-specific marker genes; cysteine-rich peptides; auxins and cytokinins; Plant Physiology; växtfysiologi;

    Sammanfattning : The actinorhizal symbiosis is entered by nitrogen-fixing actinobacteria of the genus Frankia and a large group of woody plant species distributed among eight dicot families. The actinorhizal symbiosis, as well as the legume-rhizobia symbiosis, involves the stable intracellular accommodation of the microsymbionts in special organs called root nodules. LÄS MER

  7. 15. Black Truffles of Sweden : Systematics, Population Studies, Ecology and Cultivation of Tuber aestivum syn. T. uncinatum

    Författare :Christina Wedén; Leif Tibell; Eric Danell; James M. Trappe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Tuber aestivum; Tuber uncinatum; Tuber mesentericum; ITS; spore reticulum; truffle cultivation; island ecology; populations; morphology; ecotype; Quercus robur; Biologi; Biology; Biologi;

    Sammanfattning : Tuber aestivum is an ectomycorrhizal ascomycete with underground fruit bodies. It is an economically important species, but has been regarded as endangered in Sweden. My inventory has increased the number of reported localities from 3 to 31. It has long been debated whether T. LÄS MER
