  1. 26. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae

    Författare :Helene Larsson Jönsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; UV-B; plant nutrients; photosynthesis; oxygen evolution; chlorophyll fluorescence; Cd uptake; cadmium; Arabidopsis thaliana; Brassica napus; Plant biochemistry; Växtbiokemi; Botany; Botanik;

    Sammanfattning : Plants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. LÄS MER

  3. 27. Vacuolar Ca2+-ATPases in Plants. Regulation by calmodulin binding to a N-terminal autoinhibitory domain

    Författare :Susanna Malmström; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; N terminus; autoinhibitory domain; vacuole; calmodulin; calcium; plants; Ca2 -ATPase; Växtbiokemi;

    Sammanfattning : The calcium ion (Ca2+) is essential for all plant and animal life. One important function of Ca2+ is as a second messenger in the responses of the cell to environmental and hormonal signals as well as in some intrinsic developmental processes. LÄS MER

  4. 28. Molecular Breeding of Sugar Beet, Transformation, Transgene silencing, Virus and Herbicide resistance

    Författare :Marie Mannerlöf; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agrobacterium tumefaciens; BNYVV; coat protein; CP4epsps; gene silencing; glyphosate; herbicide; rhizomania; transformation; sugar beet; Beta vulgaris L.; virus; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The main objectives in sugar beet breeding, are to improve yield, quality and to develop disease resistance. The disease resistance may be developed either by conventional, or molecular breeding techniques. The molecular breeding techniques include, methods to genetically engineer plants for expression of introduced genes. LÄS MER

  5. 29. Sesquiterpene synthases in Artemisia annua: Cloning, Expression, and Characterisation of the Recombinant Enzymes

    Författare :Per Mercke; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artemisia annua; Sesquiterpene synthases; artemisinin; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Plants produce a multitude of different compounds that may have biotic effects. Artemisia annua, produces a compound used as a drug against multi-drug-resistant strains of Plasmodium falciparum, the parasite causing malaria. LÄS MER

  7. 30. Calcium transporting ATPases in plant cells

    Författare :Malin Olbe; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Triticum aestivum; calcium; Brij 58; calmodulin; Ca2 signalling; inside-out; endoplasmic reticulum; plant; plasma membrane; proteolysis; P-type ATPase; spinach; Spinacea oleracea; trypsin; two-phase; wheat.; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. LÄS MER
