  1. 1. Non-target Effects of Genetically Modified Trees

    Författare :Patrik Blomberg; Anders Wennström; Jan Stenlid; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetically modified; GM trees; secondary metabolism; phytochemistry; Populus; transgenic; non-target effects; natural enemies; plant-pathogen herbivore interaction; environmental effects; parasitic fungi; herbivorous insect; Terrestrial ecology; Terrestisk ekologi;

    Sammanfattning : To date, few studies have focused on the effects of genetically modified trees (GM trees) on the environment. One concern with GM trees is that they may have unanticipated effects on non-target organisms, i.e. effects on organisms that are not direct targets of the genetically modified trait. LÄS MER

  3. 2. Gene technology at stake : Swedish governmental commissions on the border of science and politics

    Författare :Jenny Eklöf; Kjell Jonsson; Christer Nordlund; Susanne Lundin; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Gene technology; biotechnology; recombinant DNA technology; bioethics; ethics; risk; GMO; embryo; transgenic organisms; boundary organization; boundary object; governmental commission; regulatory policy; Sweden; public; expertise; democracy; History of science and ideas; Idé- o lärdomshistoria;

    Sammanfattning : This thesis examines the Swedish political response to the challenges posed by gene technology, seen through the prism of governmental commissions. It discerns and analyses continuities and changes in the Swedish political conception of gene technology, over the course of two decades, 1980–2000. LÄS MER

  4. 3. A functional genomics approach to PDGF and pericyte biology

    Författare :Cecilia Bondjers; Göteborgs universitet; []
    Nyckelord :PDGF; hair follicle; skin; testis; epithelial-mesenchymal interaction; microarray; pericyte; transgenic mouse;

    Sammanfattning : The rapid expansion of genome sequence data demands for increased efforts and speed concerning functional analysis of gene products. Two approaches to such analysis, namely transgenic technologies and analysis of gene expression have successfully been used to study functions of gene products in complex organisms, such as mammals.

  5. 4. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

    Författare :Malin Mejàre; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

    Sammanfattning : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. LÄS MER

  7. 5. A Chloroplast Localized Small Heat Shock Protein, Hsp21. Importance of Hsp21 in stress protection of transgenic Arabidopsis thaliana, recombinant expression and characterization of oxidation-dependent conformational changes

    Författare :Ulrika Härndahl; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; a-crystallin; sHsp; chaperone; amphipathic a-helix; oligomer; redox-regulated; methionine sulfoxidation; oxidative stress; regulation; protein structure; circular dichroism; mass spectrometry; fluorescence spectroscopy; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : A specific group of heat shock proteins, the so called small heat shock proteins (sHsps), exists in all organisms but are especially abundant in plants. The sHsps prevent aggregation of other proteins (substrate proteins) during transient heat and oxidative stress. LÄS MER
