  1. 1. Promoter Engineering for Cyanobacteria : An Essential Step

    Author : Hsin-Ho Huang; Peter Lindblad; James Golden; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; synthetic biology; cyanobacteria; promoter; engineering; TetR; DNA breathing dynamics; transcription; regulation;

    Abstract : Synthetic biology views a complex biological system as an ensemble in the hierarchy of parts, devices, systems, and networks. The practice of using engineering rules such as decoupling and standardization to understand, predict, and re-build novel biological functions from model-driven designed genetic circuits is emphasized.

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

    Author : Martin Ekman; Birgitta Bergman; Dave G. Adams; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  3. 3. Hetrocystous cyanobacteria living within symbiosomes : genetic and physiological aspects

    Author : Johanna Wouters; Birgitta Bergman; John Raven; Högskolan i Kalmar; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; Microbiology; cyanobacteria; plants; symbiosis; nitrogen-fixation;

    Abstract : The objective of the thesis was to get a deeper genetic and physiological insight into the two heterocystous cyanobacterial species known today to live within symbiosomes: the marine cyanobacterium Richelia and the terrestrial cyanobacterium Nostoc. Symbiosomes are organelle-like structures formed by algal and plant hosts that accommodate symbiotic microbes inside their cellular compartment. READ MORE

  4. 4. 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 : NATURAL SCIENCES; NATURVETENSKAP; 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. 5. Factors influencing the success of pelagic cyanobacteria

    Author : Per Hyenstrand; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Biology; cyanobacteria; inorganic nitrogen; competition; iron; phytoplankton succession; Biologi; Biology; Biologi; limnologi; Limnology;

    Abstract : Cyanobacteria are present in most aquatic systems, and pelagic bloom-forming species often flourish in lakes. Since blooms of cyanobacteria are undesirable for several reasons, e.g. they can result in foul odours and tastes as well as toxicity, these organisms have been subject to an extensive amount of research around the globe.
