  1. 1. Regulation of the cobalamin biosynthetic genes in Salmonella typhimurium

    Författare :Agneta A. Richter Dahlfors; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : .... LÄS MER

  3. 2. Studies of genes involved in regulating flowering time in Arabidopsis

    Författare :Maria Svensson; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; flowering time; fold recognition; GA biosynthesis; promoter trapping; RNA-binding; T-DNA tagging; Biology; Biologi; Naturvetenskap; Natural sciences;

    Sammanfattning : Transition from a vegetative growth phase to flowering in plants occurs in response to both environmental conditions and endogenous signals. Identification of genes that are involved in regulating the time of flowering is of great importance in agri- and horticulture. LÄS MER

  4. 3. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer

    Författare :Jean-Marc Lassance; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biosynthetic enzymes; evolution; Ostrinia nubilalis; mate choice; mate finding; olfaction; biosynthesis; speciation; moth; pheromone; olfactory receptors.;

    Sammanfattning : Chemical communication by means of sex pheromones is central to the mating systems of a wide range of organisms. Because reproductive isolation is often based on pheromone differences, understanding how pheromones diverge is necessary for a complete comprehension of the speciation process. LÄS MER

  5. 4. Effects of polyamine pool manipulation on genes expressed during the cell cycle

    Författare :Pia Berntsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal physiology; cyclin A; ODC; MCF-7; mitotic shake off; DENSPM; CHO; cDNA microarray; cell cycle; spermine; Djurfysiologi; AdoMetDC; 2D gel electrophoresis; polyamines; spermidine; putrescine;

    Sammanfattning : The polyamines - putrescine, spermidine and spermine - are polycations found within cells. They have been shown to be essential for optimal cell proliferation and cell survival. Cells maintain their polyamine levels in a well-regulated system involving biosynthesis, catabolism and uptake/excretion. LÄS MER

  7. 5. New regulators of xylem lignification in arabidopsis

    Författare :Bernadette Sztojka; Hannele Tuominen; Simon Hawkins; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Xylem; lignin; Arabidopsis; secondary cell wall; transcriptional regulation; lignin-biosynthetic gene; S G lignin ratio;

    Sammanfattning : The ability of land plants to grow upright, bear their own weight and withstand adverse environmental conditions is largely dependent on the secondary xylem tissues of the stem. The xylem cells acquire thick secondary cell walls which are composed of cellulose, hemicellulose and lignin. LÄS MER
