  1. 36. Mechanisms of unreduced gamete formation in Arabidopsis thaliana

    Författare :Jun Yi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Polyploidy is a widespread phenomenon in plants, which is commonly believed to arise through the production of unreduced (2n) gametes due to meiotic failure. Despite the importance of unreduced gamete formation for plant polyploidization, the mechanisms leading to their formation are not well understood. LÄS MER

  3. 37. Genes encoding homeodomain-leucine zipper proteins in Arabidopsis thaliana

    Författare :Eva Söderman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Plant physiology; Växtfysiologi;

    Sammanfattning : A new class of transcription factors, the homeodomain-leucine zipper (HD-Zip) proteins,have been identified in Arabidopsis thaliana. These proteins contain a homeodomainfollowed by a leucine-zipper motif, a combination so far only found in plants. LÄS MER

  4. 38. Defense gene responses toward necrotrophic fungi in Arabidopsis thaliana

    Författare :Hanneke Marjolijn Peele; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Leptosphaeria maculans an ascomycete in the diverse class of Dothideomycetes, is an devastating pathogen on Brassica crops. In this thesis, tools and knowledge in Arabidopsis thaliana was explored to enhance our knowledge on plant defense to this fungus. Mechanisms that to large extent are shared with other necrotrophic fungi. LÄS MER

  5. 39. Functional studies of the PreP peptidasome in Arabidopsis thaliana

    Författare :Stefan Nilsson; Elzbieta Glaser; Hans-Peter Braun; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Two independent endosymbiotic events gave rise to mitochondria and chloroplasts. Despite the fact that both organelles have their own small genome the majority of organellar proteins are encoded in the nucleus, synthesized in the cytosol and imported into the organelles. LÄS MER

  7. 40. The HDZip Class I Transcription Factors in Arabidopsis thaliana : Characterisation of HDZip Genes Involved in the Mediation of Environmental Signals

    Författare :Eva Henriksson; Peter Engström; Julio Salinas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Plant physiology; Växtfysiologi;

    Sammanfattning : Homeodomain leucine zipper (HDZip) proteins constitute a large family of transcription factors characterised by the presence of a DNA-binding homeodomain and an adjacent leucine zipper motif, which mediates protein-dimer formation. The HDZip genes of Arabidopsis have been divided into four classes, HDZip I-IV. LÄS MER
