  1. 1. Molecular and Metabolic Aspects of Plant and Bacterial Salt Tolerance

    Författare :Peter Olsson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknik; metabolism; gamma-aminobutyric acid; Nicotiana tabacum; salinity; hypoxia; heamoglobin; microarray; glycine betaine; NaCl; GABA; Vitreoscilla; calmodulin; Esherichia coli; tobacco; Biokemi; Metabolism; Biochemistry; Arabidopsis;

    Sammanfattning : Salt stress is one of the historically as well as potentially largest agriculture problem humans have faced. Researchers have investigated and tried to solve this problem for a long time. Over 20 reviews have been written on this topic the last five years. LÄS MER

  3. 2. Temperature effects on UV-B induced DNA damage and repair in plants and a lichen

    Författare :Markus Paulsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tobacco Nicotiana tabacum ; Temperature; Subarctic; Plants; Photoreactivation; Photolyase; Lichen; DNA damage; Cyclobutane pyrimidine dimers CPD ; 6-4 Photoproducts; Cladonia arbuscula ssp. mitis; Ultraviolet radiation; UV-B; Vaccinium vitis-idaea; Plant genetics; Växtgenetik;

    Sammanfattning : All living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. LÄS MER

  4. 3. Plant Calreticulins -Calcium-binding proteins with many functions

    Författare :Anna Christensen; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tobacco; plant; calreticulin; isoforms; Arabidopsis; localization; mouse embryonic fibroblasts;

    Sammanfattning : Endoplasmic reticulum (ER) plays an important role in protein synthesis, folding, maturation and transport of newly synthesized proteins, as well as the regulation of cellular Ca2+ homeostasis. A protein that is involved in several of these functions in the ER is calreticulin (CRT), which is a Ca2+-binding chaperone that resides in the lumen of the ER. LÄS MER

  5. 4. Asexual embryogenesis in plants

    Författare :Boel Mårtensson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; two-phase partitioning; somatic embryogenesis; pollen embryogenesis; plasma membrane; peroxidase; Daucus carota isoperoxidase; Nicotiana tabacum; Ca2 transport; cell shape; calmodulin; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Sammanfattning : The capacity of somatic cells and pollen grains or microspores to undergo embryogenesis is an important property used in improvement and regeneration of plants. Furthermore, somatic embryogenesis as well as pollen embryogenesis show many similarities with zygotic embryogenesis and are, thus, good model systems. LÄS MER

  7. 5. Understanding and manipulating primary cell walls in plant cell suspension cultures

    Författare :Felicia Leijon; Vincent Bulone; Katja Salomon Johansen; KTH; []
    Nyckelord :Callose synthase; carbohydrate-binding module; cell wall engineering; cellulose microfibril; cellulose nanocrystal; glycosyltransferase; mass spectrometry; plasmodesmata; Populus; primary cell wall; radiometric assay; spectrophotometric assay; Biotechnology; Bioteknologi;

    Sammanfattning : The cell wall is required for many aspects of plant function and development. It is also an accessible and renewable resource utilized both in unrefined forms and as raw material for further development. Increased knowledge regarding cell wall structure and components will contribute to better utilization of plants and the resources they provide. LÄS MER
