  2. 1. Infection biology of the plant pathogenic fungus Bipolaris sorokiniana

    Author : Dace Apoga; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microscopy; Hordeum vulgare; barley; virulence; prehelminthosporol; phytotoxins; proteins; adhesion; fimbriae; extracellular matrix; Helminthosporium sativum; Cochliobolus sativus; Plant pathogenic fungi; Bipolaris sorokiniana; two-dimensional gel electrophoresis; mass spectrometry; gas chromatography; Ecology; Ekologi;

    Abstract : Bipolaris sorokiniana is a fungal pathogen causing severe disease mainly in wheat and barley worldwide. In this thesis two aspects of the infection process were investigated: the adhesion mechanism of the fungus and the role of the non-host specific phytotoxin prehelminthosporol (PHL) in the disease. Adhesion of B. READ MORE

  4. 2. Prioritization of phytotoxins according to their threat to water quality

    Author : Inés Rodríguez Leal; Matthew MacLeod; Ullrika Sahlin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Natural toxins are pollutants of emerging concern. Despite being ubiquitous in the European environment, thus far little action has been taken to conduct screening-level assessment of their presence in drinking water. READ MORE

  5. 3. Internal oxygen transport to below-ground parts: importance for emergent macrophytes

    Author : Viveka Vretare Strand; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; water depth; zonation; phenotypic plasticity; biomass allocation; pressurised ventilation; oxygen; Phragmites australis; emergent macrophytes; common reed; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi;

    Abstract : This thesis examines factors regulating growth and distribution of emergent plants with focus on effects of oxygen supply to the roots. Greenhouse experiments revealed that P. australis acclimatizes to specific water depths with phenotypic plasticity. READ MORE
