  1. 11. Metabolic engineering of Crambe abyssinica for producing high erucic acid oil

    Författare :Rui Guan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Vegetable oils are renewable and more environmentally friendly than fossil oils, and thus are good alternatives to fossil oils for industrial applications. Erucic acid (C22:1Δ13) is a valuable feedstock in the chemical industry. The current plant sources for erucic acid production are high erucic acid rapeseed (HEAR) and mustard. LÄS MER

  3. 12. Carbon allocation in underground storage organs : studies on accumulation of starch, sugars and oil

    Författare :Helle Turesson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : By increasing knowledge of carbon allocation in underground storage organs and using the knowledge to improve such crops, the competitiveness of these types of storage organs can be strengthened. Starch is the most common storage compound in tubers and roots, but some crops accumulate compounds other than starch. LÄS MER

  4. 13. Analyses of genetic diversity and desirable traits in sesame (Sesamum indicum L., Pedaliaceae) : implication for breeding and conservation

    Författare :Toan Duc Pham; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Sesame (Sesamum indicum L., Pedaliaceae) is a traditional oil crop cultivated in Vietnam and Cambodia. It is known as the king of oil seeds in Vietnam due to the high oil content (50-60%) in its seed. LÄS MER

  5. 14. Characterization of auxiliary membrane proteins in the chloroplast of Arabidopsis thaliana

    Författare :Lotta von Sydow; Christiane Funk; Wolfgang Schröder; Thomas Pfannschmidt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Arabidopsis; chaperone; chloroplast; Cytochrome b559; FtsH; membrane proteins; photosynthesis; Photosystem II; protease; PsbY.; Arabidopsis; chaperone; Cytochrome b559; fotosyntes; fotosystem II; FtsH; kloroplast; membranprotein; proteas; PsbY.; biokemi; Biochemistry;

    Sammanfattning : In nature, sessile plants have to adapt to their environment and to the never ending changes they are exposed to. They do so mainly by proteomic and metabolomic changes. In all cells, there are complex networks of auxiliary proteins that are responsible for quality control of all the cell's proteins. LÄS MER

  7. 15. Regional and local variation in plant species richness

    Författare :Cecilia Dupré; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; coastal meadows; deciduous forests; dry grasslands; grazing; habitat configuration; habitat quality; hump-shaped curve; life history traits; regional species pool; soil factors; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : In this thesis, I examine the variation in plant species richness along gradients of productivity and disturbance in grasslands and forest habitats in southern Sweden, and I compare the documented patterns with theoretical predictions. Moreover, I evaluate the relative importance of habitat quality and habitat configuration for the occurrence of field layer species in deciduous forests. LÄS MER
