  2. 1. From green to yellow : a leaf story

    Author : Olivier Keech; Per Gardeström; Pierre Dizengremel; Lee Sweetlove; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplasts; cytoskeleton; darkness; metabolism; microscopy; mitochondria; microtubules; senescence; system redox; Plant physiology; Växtfysiologi;

    Abstract : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. READ MORE

  4. 2. Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees

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

    Abstract : 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.

  5. 3. Thermal plasticity and limitations in tropical trees

    Author : Maria Wittemann; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; African tropical forest; chlorophyll fluorescence; climate change; drought; hydraulic; montane; photosynthesis; respiration; successional strategies; temperature; tropical trees; warming;

    Abstract : Tropical forests are the most carbon dense and biodiverse terrestrial biome on earth. In a time of global warming and biodiversity crisis, their preservation must be of high priority. At the same time, they likely operate close to their thermal limits because of a historically and seasonally stable environment. READ MORE

  6. 4. Preparation of leaf mitochondria and studies on mitochondrial photorespiratory reactions

    Author : Per Gardeström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; leaf mitochondria; photorespiration; aqueous two-phase system; Percoli gradient; cytochromes; glycine decarboyxlase; serine hydroxymethyltransferase; inhitors of photorespiration;

    Abstract : A procedure for the preparation of spinach leaf mitochondria was developed. The procedure combines differential centrifugation, partition in dextran- polyethyleneglycol two-phase system and Percoli density gradient centri- fugation. The different steps separate the material mainly according to size, surface properties and density, respectively. READ MORE

  7. 5. Low temperature acclimation in plants : alterations in photosynthetic carbon metabolism

    Author : Maria Lundmark; Vaughan Hurry; Charles Guy; Umeå universitet; []
    Keywords : Plant physiology; cold acclimation; carbon metabolism; photosynthesis; respiration; Växtfysiologi; Physiological Botany; fysiologisk botanik;

    Abstract : Although low temperature plays an important role in determining agricultural yield, little is known about the effect on the underlying biochemical and physiological processes that influence plant growth. Photosynthesis and respiration are central to plant growth and both processes are heavily affected by temperature. READ MORE
