  1. 1. Dissecting the photosystem II light-harvesting antenna

    University dissertation from Umeå : Fysiologisk botanik

    Author : Jenny Andersson; Umeå universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; carotenoid; feedback de-excitation; fitness; LHC; NPQ; photosynthesis; state transitions; xanthophyll; Växtfysiologi; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; Physiological Botany; fysiologisk botanik;

    Abstract : In photosynthesis, sunlight is converted into chemical energy that is stored mainly as carbohydrates and supplies basically all life on Earth with energy.In order to efficiently absorb the light energy, plants have developed the outer light harvesting antenna, which is composed of ten different protein subunits (LHC) that bind chlorophyll a and b as well as different carotenoids.

  2. 2. 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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Annelie Carlsbecker; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; Fysiologisk botanik; Physiological Botany;

    Abstract : 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. READ MORE

  3. 3. Crustacean immunity : Characterization of some crayfish blood proteins

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pia Gambäck Keyser; Uppsala universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; fysiologisk mykologi; Physiological Mycology;

    Abstract : The cDNA sequence and some properties of a previously purified #x03B2;-1,3-glucan binding protein are reported here. The putative amino acid sequence (predicted molecular mass: 152 kDa) of the protein did not show any significant similarity to any known protein, but an RGD motif and a region with slight similarity to bacterial glucanase was found.

  4. 4. The light-harvesting antenna of higher plant photosystem I

    University dissertation from Umeå : Umeå universitet

    Author : Ulrika Ganeteg; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; fitness; LHC; photosynthesis; Växtfysiologi; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi;

    Abstract : During photosynthesis, two multi-protein complexes, photosystems (PS) I and II work in tandem to convert the light-energy absorbed by the light-harvesting antennae into chemical energy, which is subsequently used to assimilate atmospheric carbon dioxide into organic carbon compounds. This is the main nutritional basis for life on Earth. READ MORE

  5. 5. Genetic variability and nitrogenase activity of cyanobacterial communities associated with tropical seagrass meadows (western Indian Ocean)

    University dissertation from Stockholm : Department of Botany, Stockholm University

    Author : Mariam Hamisi; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; nitrogenase activity; diazotrophs; seagrass; western Indian ocean; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : Tropical seagrass ecosystems are highly productive and important for sustaining marine life and associated coastal societies. In this study, the diversity and role of nitrogen-fixing cyanobacteria associated with five common seagrass genera in coastal regions of the western Indian Ocean (WIO; Tanzania) were examined, as well as the impact of anthropogenic activities.
