  1. 1. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification

    Författare :Gösta Lilius; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycine betaine; gene; freezing; flooding; drought; dicoteledones; desiccation; compatible solutes; cold; choline dehydrogenase; chill; CDH; betaine; betA; alkaloids anoxia; affinity purification; affinity tags; handles; hemoglobin; hypoxia; low temperatu; Biotechnology; Bioteknik;

    Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.

  3. 2. Physiological responses of marine and brackish Fucus vesiculosus L. with respect to salinity

    Författare :Maria Gylle; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acclimation; Bothnian Sea; compatible solutes; desiccation; fluorescence; F. vesiculosus; F. radicans; immunoblot; mannitol; photosynthesis; Rubisco; salinity; Algfysiologi; Biology; Biologi;

    Sammanfattning : The intertidal brown alga Fucus vesiculosus L. is mainly a marine species (34 practical salinity units, psu), but the alga also grows in the sublittoral of the brackish Bothnian Sea (part of the Baltic Sea; 5 psu). LÄS MER

  4. 3. Biological growth on rendered façades

    Författare :Sanne Johansson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; render; radiation; photosynthesis; moulds; mosses; mortar; moisture; lichens; Imaging-PAM; humidity; heat capacity; heat; ETICS; algae; biological growth; calorimetry; desiccation tolerance;

    Sammanfattning : Biological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on.

  5. 4. Planting and survivability of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) in Sweden : Questions of seedling storability, site preparation, bud burst timing and freezing tolerance

    Författare :Cecilia Malmqvist; Harald Säll; Douglass F. Jacobs; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; regeneration; provenances; coastal; interior; frost damage; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : The non-native Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) has been grown to a limited extent in the southern part of Sweden since the early 1900s. A more extensive use has probably been curtailed by its known susceptibility to damage by frost, pine weevil and other pests. LÄS MER

  7. 5. Genetic variation and local adaptation in peripheral populations of toads

    Författare :Björn Rogell; Jacob Höglund; Anssi Laurila; Josh Van Bushkirk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Populationsbiologi; Population Biology;

    Sammanfattning : Northern fringe populations generally have low amounts of genetic variation and inhabit habitats where specific adaptations are needed. On the Swedish west coast, the natterjack toad (Bufo calamita) inhabits skerry islands. LÄS MER
