  1. 1. 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

  3. 2. The role of Nkx proteins neuronal and glial specification

    Författare :Anna Vallstedt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : During development, different classes of neurons and glia are generated from proliferative progenitor cells lining the ventricles of the brain and the lumen of the spinal cord. A central issue in developmental neuroscience is to understand the mechanisms by which these cells are generated in space and over time. LÄS MER

  4. 3. Interactions of the Cell-Penetrating Peptide Penetratin with Model Membranes and Live Cells

    Författare :Daniel Persson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antisense; antennapedia homeodomain; delivery vector; cell-penetrating peptide; protein transduction; uptake; membrane translocation; penetratin; confocal microscopy; vesicle;

    Sammanfattning : The delivery of large, hydrophilic molecules, such as proteins and oligonucleotides, to the cytoplasm and nucleus of cells is problematic due to their generally low plasma membrane permeability. With the identification of a number of cell-penetrating peptides, capable of mediating non-endocytotic, intracellular delivery of macromolecular cargos, this obstacle now seems surmountable. LÄS MER

  5. 4. Functional analysis of homeodomain-leucine zipper transcription factors in Arabidopsis thaliana

    Författare :Henrik Johannesson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

    Sammanfattning : Homeodomain-leucine zipper (HDZip) proteins constitute a large family of transcription factors apparently unique to plants. To elucidate the function of these factors, the biochemical properties in vitro as well as the effects on transgenic plants when expressed at high levels were studied. LÄS MER

  7. 5. HDZip I Transcription Factors in Arabidopsis thaliana : Expression and Function in Relation to Environmental Stress Conditions

    Författare :Anna S. B. Olsson; Peter Engström; Eva Söderman; Pieter B. F. Ouwerkerk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; homeodomain leucine zipper; ABA; transcription factor; water deficit; Arabidopsis thaliana; Biologi; Biology; Biologi;

    Sammanfattning : The homeodomain leucine zipper (HDZip) proteins constitute a plant-specific family of transcription factors, that based on sequence criteria have been grouped into four classes, HDZip I-IV. This thesis describes the phylogeny, function, expression patterns and regulation of the HDZip class I genes in the model species Arabidopsis thaliana. LÄS MER
