  2. 21. Application of Molecular Markers in Sugar Beet Breeding

    Author : Annika Hjerdin Panagopoulos; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; breeding; marker application; molecular markers; sugar beet;

    Abstract : Around 1750 a German chemist discovered it to be possible to extract sugar crystals from beet juice. Since then, breeding and improved agricultural practices have increased the concentration of sucrose per root from around 4% to around 18%. READ MORE

  4. 22. Weighted Bergman kernels and biharmonic Green functions

    Author : Stefan Jakobsson; Matematikcentrum; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; singularity resolution of Bergman kernels; Hadamard s variational formula; weighted Bergman kernel; weighted biharmonic Green function; Friedrichs operator; Plant biochemistry; Växtbiokemi;

    Abstract : The main theme of this thesis is the connection between weighted biharmonic Green functions and weighted Bergman kernels. In the first paper, which is a joint work with H. Hedenmalm and S. Shimorin, we prove that weighted biharmonic Green functions are positive for weights which satisfy a mean-value condition and whose logarithms are subharmonic. READ MORE

  5. 23. Plant aquaporins

    Author : Ingela Johansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water deficit; calcium; plasma membrane; Plant biochemistry; channel; phosphorylation; Växtbiokemi;

    Abstract : Aquaporins are integral membrane proteins that specifically transports water. In plants, aquaporins have been identified in the plasma membrane and in the vacuolar membrane. READ MORE

  6. 24. Geophysical Applications of Vegetation Modeling

    Author : Jed O Kaplan; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Växtbiokemi; Plant biochemistry; CH4; CO2; stable isotopes; carbon cycle; wetland; ice core; methane; Holocene; mammoths; tundra; ice age; LGM; biogeography; biome; biogeochemistry; Vegetation model; Miljökemi; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Abstract : This thesis describes the development and selected applications of a global vegetation model, BIOME4. The model is applied to problems in high-latitude vegetation distribution and climate, trace gas production, and isotope biogeochemistry. READ MORE

  7. 25. The Aquaporins - Expression and Regulation of Water Channel Proteins

    Author : Maria Karlsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; immunocytochemistry; overexpression; phosphorylation; aquaporin; water channel; Växtbiokemi; Chemistry; Kemi;

    Abstract : Aquaporins are integral membrane proteins that function as water channels highly specific for water or as aquaglyceroporins permeable to water as well as small solutes such as glycerol and urea. The model plant Arabidopsis thaliana has 35 genes encoding aquaporin proteins. READ MORE
