  2. 1. On the ecophysiology of Baltic cyanobacteria focusing on bottom-up factors

    Author : Malin Mohlin; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Allelopathy; Aphanizomenon sp.; Baltic Sea; Cyanobacteria; Diazotrophic; Multi-factorial; Nitrogen; Nodularin; photosynthetic active radiation; Phosphorus; ultraviolet radiation; UV-A; UV-B;

    Abstract : Cyanobacterial blooms in the Baltic Sea are dominated by diazotrophic cyanobacteria, i.e. Aphanizomenon sp. and Nodularia spumigena. READ MORE

  4. 2. Cyanobacteria in symbiosis with boreal forest feathermosses : from genome evolution and gene regulation to impact on the ecosystem

    Author : Denis Warshan; Ulla Rasmussen; Elke Dittmann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Feathermosses; Symbiosis; Boreal forest; Gene flow; Proteogenomic; Transcriptomic; Community structure and composition; Dinitrogen fixation; Plant Physiology; växtfysiologi;

    Abstract : Among dinitrogen (N2)-fixing some cyanobacteria can establish symbiosis with a broad range of host plants from all plant lineages including bryophytes, ferns, gymnosperms, and angiosperms. In the boreal forests, the symbiosis between epiphytic cyanobacteria and feathermosses Hylocomium splendens and Pleurozium schreberi is ecologically important. READ MORE

  5. 3. Cyanobacterial Nitrogen Fixation in the Baltic Sea : With focus on Aphanizomenon sp

    Author : Jennie B. Svedén; Jakob Walve; Helle Ploug; Angela Wulff; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; Baltic Sea; nitrogen fixation; Aphanizomenon sp.; dissolved nitrogen; particulate nitrogen; sedimentation; Marine Ecology; marin ekologi;

    Abstract : Cyanobacteria are widely distributed in marine, freshwater and terrestrial habitats. Some cyanobacterial genera can convert di-nitrogen gas (N2) to bioavailable ammonium, i.e. perform nitrogen (N) fixation, and are therefore of profound significance for N cycling. READ MORE

  6. 4. Cyanobacteria in symbiosis with plants : Protein patterns and regulatory mechanisms

    Author : Martin Ekman; Birgitta Bergman; Dave G. Adams; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; symbiosis; Nostoc; Gunnera; Azolla; nitrogenase; modification; heterotrophic; proteomics; unsequenced; Plant physiology; Växtfysiologi;

    Abstract : Cyanobacteria belonging to the heterocystous genus Nostoc, capable of oxygenic photosynthesis and nitrogen fixation via the enzyme nitrogenase, may form symbiotic associations with plants. In these associations most of the N2 fixed by the symbiotic cyanobacteria (cyanobiont) is transferred to the host, which in turn supplies the cyanobiont with fixed carbon. READ MORE

  7. 5. Functional studies on the Light-harvesting-Like (LiL) Proteins in Cyanobacteria and Cryptophytes

    Author : Tania Tibiletti; Christiane Funk; Martin Hagemann; Umeå universitet; []
    Keywords : Photosynthesis; cyanobacteria; Guillardia theta; photosystem II; chlorophyll-binding proteins; onehelix LiL proteins; photoprotection; biokemi; Biochemistry;

    Abstract : The light-harvesting like (LiL) proteins are a widely spread group of proteins within photosynthetic organisms. They are membrane proteins composed of one to four transmembrane helices and – in homology to the light-harvesting complexes of algae and higher plants – at least one of these transmembrane helices contains the chlorophyll a/b-binding (CAB) domain.
