  2. 21. New regulators of xylem lignification in arabidopsis

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

    Abstract : 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. READ MORE

  4. 22. Regulation of mitochondrial gene expression in metazoa

    Author : Ana Bratic; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Drosophila melanogaster; ;

    Abstract : Mitochondria are essential organelles of eukaryotic cells and their main function is to provide the cell with the ubiquitously used energy currency ATP. Impaired energy conversion caused by mitochondrial dysfunction is a direct cause of several human diseases. READ MORE

  5. 23. Changes in global gene expression and auxin dynamics during embryo development in conifers

    Author : Daniel Vestman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Conifers are of great economical importance, but our knowledge about how the development of conifers is regulated is limited. The over-all aim of this study has been to gain a better understanding of the molecular regulation of embryo development in conifers. READ MORE

  6. 24. Gene Expression in the Brains of Two Lines of Chicken Divergently Selected for High and Low Body Weight

    Author : Sojeong Ka; Finn Hallböök; Tom Porter; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chicken; juvenile body weight; divergent selection; gene expression; DNA microarray; quantitiative RT-PCR; hypothalamus; neural plasticity; melanocortin system; endogenous retrovirus; carnitine palmitoyltransferase-1b; Neurobiology; Neurobiologi; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Abstract : Artificial divergent selection of chickens for high and low body weight at 8 weeks of age has produced two lines: the high (HWS) and low (LWS) body weight chicken lines. In addition to the difference in body weight, the lines show extreme differences in feeding behaviour and body composition. READ MORE

  7. 25. Gene silencing and expression during mammalian development : The special case of the imprinted H19 gene

    Author : Kristian Svensson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Biology; Biologi; zoologisk utvecklingsbiologi; Animal Development;

    Abstract : Embryonic development consists of a vast number of fine-tuned, complex processesthat organise the body plan and individual organs. To enable developmental decisions,genes pivotal for normal development must be stably activated and silenced, asappropriate. READ MORE
