  1. 31. The actinorhizal symbiosis of Datisca glomerata: Search for nodule-specific marker genes

    Författare :Irina V. Demina; Katharina Pawlowski; Franziska Krajinski; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actinorhizal symbiosis; Datisca glomerata; nodule transcriptome; nodule-specific marker genes; cysteine-rich peptides; auxins and cytokinins; Plant Physiology; växtfysiologi;

    Sammanfattning : The actinorhizal symbiosis is entered by nitrogen-fixing actinobacteria of the genus Frankia and a large group of woody plant species distributed among eight dicot families. The actinorhizal symbiosis, as well as the legume-rhizobia symbiosis, involves the stable intracellular accommodation of the microsymbionts in special organs called root nodules. LÄS MER

  3. 32. Seagrass productivity : from plant to system

    Författare :Diana Deyanova; Mats Björk; Mirta Teichberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Seagrass; Chlorophyll a fluorescence; Ageing; Productivity; Seasonality; Stress response; Plant Physiology; växtfysiologi;

    Sammanfattning : Seagrasses form one of the most productive habitats on earth and are recognized as very efficient carbon sinks. The levels and patterns of productivity within and across different seagrass systems vary widely due to natural or human-induced factors. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 35. The neurotoxin β-N-methylamino-L-alanine (BMAA) : Sources, bioaccumulation and extraction procedures

    Författare :Sandra Ferreira Lage; Sara Rydberg; Ulla Rasmussen; Hanna Mazur-Marzec; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant Physiology; växtfysiologi;

    Sammanfattning : β-methylamino-L-alanine (BMAA) is a neurotoxin linked to neurodegeneration, which is manifested in the devastating human diseases amyotrophic lateral sclerosis, Alzheimer’s and Parkinson’s disease. This neurotoxin is known to be produced by almost all tested species within the cyanobacterial phylum including free living as well as the symbiotic strains. LÄS MER
