  1. 6. 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

  3. 7. Gene silencing mechanisms in Phytophthora infestans

    Författare :Vetukuri Ramesh; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The hemibiotrophic oomycete, Phytophthora infestans, causes late blight on potato and tomato. This destructive pathogen is well known for the rapidity with which it overcomes host resistance. This thesis focuses on the molecular basis of gene (RNA) silencing in P. infestans and the role it may have in its genome biology and pathogenesis. LÄS MER

  4. 8. On aging and the role of Ubp3 in heterochromatic gene silencing and protein quality control

    Författare :David Öling; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aging; Protein damage; Segregation; Transcriptional silencing; rDNA; UBP3; SIR2; Protein aggregates;

    Sammanfattning : Aging is characterized by a build-up of damage in organisms ranging from protists to multi-cellular species. This damage adversely affects core components such as DNA and proteins which are necessary to sustain life. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 10. Mechanistic characterization of post-transcriptional gene silencing

    Författare :Cecilia Dahlgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : With the ongoing task of identifying and characterizing genes in the human genome, there is a great demand for tools to study these genes. Today, reverse genetics is the most effective way to explore gene function. This involves suppression of the gene of interest by a set of manipulation techniques. LÄS MER
