  3. 22. Detection, transfer and role of an environmentally spread neurotoxin (BMAA) with focus on cyanobacteria and the Baltic Sea region

    Författare :Lotta Berntzon; Birgitta Bergman; Geoffrey Codd; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; β-N-methylamino-L-alanine; BMAA; cyanobacteria; Baltic Sea; blooms; neurotoxin; neurodegenerative diseases; amyotrophic lateral sclerosis; ALS; nitrogenase; nitrogen fixation; Plant Physiology; växtfysiologi;

    Sammanfattning : β-N-methylamino-L-alanine (BMAA) is one of the more recently discovered bioactive compounds produced by cyanobacteria. BMAA is a non-protein amino acid reported present in human brain tissues of patients deceased from a neurodegenerative disease, such as Alzheimer´s disease or amyotrophic lateral sclerosis (ALS).

  4. 23. Cellular Control and Physiological Importance of Vascular Lignification

    Författare :Leonard Blaschek; Edouard Pesquet; Richard Sibout; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; växtfysiologi; Plant Physiology;

    Sammanfattning : Lignin is indispensable for vascular plants. It allows their cells to coalesce into gravity-defying giants, hardens them to withstand pressures and predators, and waterproofs them to allow the flow of water only where it is advantageous. LÄS MER

  5. 24. Beyond carbon-limitation : A re-evaluation of the ecological role of photorespiration and direct oxygen photoreduction in seagrasses

    Författare :Pimchanok Buapet; Mats Björk; Ilana Berman-Frank; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon limitation; Chlorophyll fluorescence; Electron transport rate; Irradiance; Mehler reaction; Non-photochemical quenching; Photorespiration; Photosynthetic activity; Plant Physiology; växtfysiologi;

    Sammanfattning : Seagrasses living in shallow coastal waters are regularly subjected to changes in environmental conditions including the two essential factors for photosynthesis: dissolved inorganic carbon (DIC) and irradiance. This thesis focuses on the photosynthetic responses of seagrasses to carbon limitation induced by community metabolism and/or high light intensities. LÄS MER

  7. 25. MADS-Box Gene Phylogeny and the Evolution of Plant Form : Characterisation of a Family of Regulators of Reproductive Development from the Conifer Norway Spruce, Picea abies

    Författare :Annelie Carlsbecker; Quentin Cronk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Plant physiology; Växtfysiologi; Fysiologisk botanik; Physiological Botany;

    Sammanfattning : The evolutionary relationships between the angiosperm floral organs and the reproductive organs of other seed plants is not known. Flower organ development requires transcription factors encoded by the MADS-box genes. LÄS MER
