  1. 1. Dispersal in free-living, marine, benthic nematodes : passive or active processes?

    Författare :Jörgen Ullberg; Emil Ólafsson; John Lambshead; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nematod; dispersial; water column; choice; algal mats; disturbance; meiofauna; community; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Meiofauna, and especially marine nematodes are common in sediments around the world. Despite very wide ranging distributions in many nematode species, little is presently known about their dispersal mechanisms shaping these patterns. Rafting, and perhaps ballast water transport has been suggested as viable means for nematode long-range transport. LÄS MER

  3. 2. Identification of Virulence Factors in Nematode-Trapping Fungi - Insights from Genomics, Transcriptomics and Proteomics

    Författare :Karl-Magnus Andersson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nematode-trapping fungi; comparative genomics; comparative transcriptomics; proteomics; virulence factors; parasitism;

    Sammanfattning : Nematode-trapping fungi are soil-living organisms with the unique ability to capture and infect free-living nematodes. The interest in studying these fungi arises from their potential use as biological control agents for plant- and animal-parasitic nematodes. LÄS MER

  4. 3. Ecology of nematophagous fungi in agricultural soils

    Författare :Lotta Persmark; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic farming; Fungistasis; Competition; Bacteria; Conidial traps; Rhizosphere; Seasonal variation; Distribution; Endoparasitic; Nematode; Nematode-trapping; Ecology; Ekologi;

    Sammanfattning : Nematophagous fungi possess various mechanisms for infecting nematodes, and are either obligate parasites or facultative saprophytes. Nematophagous fungi have a potential as biological control agents against plant- and animal-parasitic nematodes. LÄS MER

  5. 4. Fungal Lectins. Molecular structure and function of a member of a novel lectin family

    Författare :Stefan Rosén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; possible functions; expression; localization; binding specificities; primary and secondary structure; Agaricus bisporus; Arthrobotrys oligospora; Fungi; novel lectin family; Biology; Biologi;

    Sammanfattning : Lectins defined as non-enzyme, non-immunoglobulin carbohydrate binding proteins, have been found in a wide variety of viruses, bacteria, fungi, plants and animals. Although lectins have been purified from more than 60 different species of fungi, the structure and biological functions of these proteins are not well known. LÄS MER
