  2. 1. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

    Author : Kristofer Bodvard; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

    Abstract : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. READ MORE

  4. 2. Coordination of two different genomes in response to light and stress

    Author : Louise Norén Lindbäck; Åsa Strand; Antony Dodd; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

    Abstract : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. READ MORE

  5. 3. Illumination in single cell optical microscopy studies - friend and foe

    Author : Kristofer Bodvard; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; yeast; transcription factors; signalling; fluorescence microscopy; Saccharomyces cerevisiae; light-induced stress; phototoxicity; single cell imaging;

    Abstract : This thesis focuses on how to use light as a biological stress factor in optical microscopy experiments and simultaneously use the illumination to image the spatial and temporal protein dynamics in single yeast cells. The stress responses to environmental changes other than light have been extensively investigated in budding yeast, Saccharomyces cerevisiae, often using techniques based on population averages.

  6. 4. Communicate or die : signalling in Drosophila immunity

    Author : Karin Borge-Renberg; Dan Hultmark; Michéle Crozatier; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; innate immunity; PGRP-LC; pattern recognition; JNK; antimicrobial peptides; Molecular biology; Molekylärbiologi;

    Abstract : In general the work behind this thesis has revolved around the interesting pattern recognition gene family PGRPs (peptidoglycan recognition proteins). In particular the transmembrane PGRP-LC and to investigate its multifaceted role in the immune response of the fruit fly. READ MORE

  7. 5. Regulation of chloroplast development during the greening process

    Author : Yan Ji; Åsa Strand; Eevi Rintamäki; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; light response; anterograde signalling; plastid transcription; chloroplast development; photosynthesis; bZIP; PEP complex; de-etiolation; molekylärbiologi; Molecular Biology;

    Abstract : Upon light exposure, the expression of one-third of the nuclear-encoded genes is changing, including genes encoding many chloroplast-targeted proteins responsible for the initiation of plastid transcription and the establishment of photosynthesis. The control of the nuclear-encoded genes involved in the development of chloroplast is referred to as anterograde signalling. READ MORE
