  1. 1. Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees

    Författare :Myriam Mujawamariya; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide; Climate change; Drought; Elevation gradient; Photosynthesis; Respiration; Tropical montane forest; Tropical trees; Warming;

    Sammanfattning : Tropical climate is getting warmer, with more pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, such as photosynthesis and leaf respiration, to these new conditions.

  3. 2. Molecular Mechanisms Optimizing Photosynthesis during High Light Stress in Plants

    Författare :Lan Yin; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; light stress; photosynthesis; chloroplast;

    Sammanfattning : Oxygenic photosynthesis is the process by which plants, algae and cyanobacteria use solar energy to convert water and carbon dioxide into molecular oxygen and carbohydrates. Photosynthesis sustains life on Earth since it provides not only energy for individual growth, but also represents the starting point of the food chain for most living organisms. LÄS MER

  4. 3. Protein phosphorylation and proteolysis - regulation and adaptive responses in photosynthesis

    Författare :Jens Forsberg; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; proteolysis; Plant biochemistry; protease; two-component systems; protein kinase; protein phosphorylation; state transitions; light-harvesting antenna; photosynthesis; chloroplast;

    Sammanfattning : Just as all other organisms, plants adapt to various environmental conditions. This work focuses on the role of chloroplast light harvesting complex II, LHCII, in adaptation of photosynthesis to changed light conditions. LÄS MER

  5. 4. Microbial Electrochemical System: extracellular electron transfer from photosynthesis and respiration to electrode

    Författare :Kamrul Hasan; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biological photovoltaics; electron transfer; electrode; Rhodobacter capslatus; thylakoid membranes; cyanobacteria; algae; photosynthesis; light; photocurrent; electrochemistry;

    Sammanfattning : The electrochemical communication between microorganisms and electrodes has substantial implications both for basic understanding of biological electron transfer as well as in diverse applications, such as, microbial electrochemical system (MES), microbial biosensors and in production of valuable chemicals. In these systems the extracellular electron transfer (EET) from microbial metabolism to electrodes is restricted due to the insulated cellular exterior made of lipid structures. LÄS MER

  7. 5. Methods for measurements of chlorophyll fluorescence, luminescence and photosynthesis in intact plants

    Författare :Erik Sundbom; Thor Bernt Trondheim Melö; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Luminiscence; delayed light emission; phytoluminography; fluorescence; in vivo chlorophyll a^ fluorescence; photosynthesis; electron transport; frost tolerance; intact plants; Physiological Botany; fysiologisk botanik;

    Sammanfattning : Methods were developed to study delayed light emission (luminiscence) and fluorescence changes in intact leaves of plants. Delayed light emission, detected from plants in darkness, was used to produce images of the plant leaves. The procedure was termed "phytoluminography". LÄS MER
