  1. 11. Atmospheric transport of persistent organic pollutants to aquatic ecosystems

    Författare :Cecilia Agrell; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Temperature; Latitude; Deposition; PCB; Baltic Sea; Ekologi;

    Sammanfattning : The load of persistent organic pollutants (POPs) is considered high in the Baltic ecosystem. The Baltic Sea spans over 12 latitudes and the regional differences in climate affect the behavior of POPs. LÄS MER

  3. 12. Trichoderma viride alamethicin and plant cells - Action, response and resistance

    Författare :Mari Aidemark; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; Nicotiana tabacum; cell cultures; alamethicin; cell permeabilisation; resistance; callose; BY-2;

    Sammanfattning : Alamethicin is a membrane active peptide secreted from the soil-living fungus Trichoderma viride. When coexisting with T. Viride, plant roots are exposed to alamethicin, which has the ability to elicit formation of volatile compounds involved in pathogen defence. LÄS MER

  4. 13. Murine Systemic Lupus erythematosus : cellular regulation and molecular mechanisms behind the formation of autoantibodies in autoimmune disease

    Författare :Marta E. Alarcón-Riquelme; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cytologi; Cellbiologi; Immunologi;

  5. 14. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil

    Författare :Louise Aldén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antibiotics; Bacteria; Community; Fungi; Leucine incorporation; Phenols; Soil; Pollution-Induced Community Tolerance PICT ;

    Sammanfattning : The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. LÄS MER

  7. 15. Defence and signalling in Potato-Phytophthora infestans interactions

    Författare :Ashfaq Ali; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytophthora infestans; Plant defence; hypersensitive response; resistance; susceptibility;

    Sammanfattning : Potato is one of the major food crops and its yield is severely affected by late blight disease caused by Phytophthora infestans. P. infestans has the ability to manipulate plant defence signalling by secreting effector molecules causing so called effector triggered susceptibility. LÄS MER
