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

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

    Abstract : 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. READ MORE

  2. 2. Studies on cell wall recycling and modification in Gram-negative bacteria

    Author : Michael C. Gilmore; Felipe Cava; Peter A Lind; Teresa Frisan; Jean-François Collet; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peptidoglycan recycling; bacterial cell wall; antibiotics; Agrobacterium tumefaciens; Escherichia coli; Legionella pneumophila; mikrobiologi; Microbiology; Biochemistry; biokemi;

    Abstract : The bacterial cell wall is made from peptidoglycan (PG), a heteropolymer which forms a bag-like exoskeleton that envelopes the cell. PG is constantly remodelled during growth and division, and in response to environmental stimuli. READ MORE

  3. 3. Influence of soil amendments and soil properties on macro– and micronutrient availability to microorganisms and plants

    Author : Atefeh Ramezanian Bajgiran; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Utilising by-products from industrial and domestic activities and from bioenergy production is one of the new ways of recovering and re-using nutrient resources in agriculture. However, these by-products can potentially add toxic elements or alter soil properties in ways that harm the soil and related environments. READ MORE

  4. 4. Lipids in seeds of oat (Avena spp.), a potential oil crop : content, quality, metabolism, and possibilities for improvement

    Author : Svetlana Leonova; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : New oil crops with high yield and oil content are urgently needed. Oat is the only cereal that accumulates substantial amount of lipids in the endosperm. This gives it potential as an oil crop, which could address both nutritional and environmental concerns of modern society. READ MORE

  5. 5. Quantum chemical studies of epoxide-transforming enzymes

    Author : Kathrin H. Hopmann; Hans Ågren; Margareta Blomberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Abstract : Density functional theory is employed to study the reaction mechanisms of different epoxide-transforming enzymes. Calculations are based on quantum chemical active site models, which are build from X-ray crystal structures. The models are used to study conversion of various epoxides into their corresponding diols or substituted alcohols. READ MORE
