  2. 16. Coping with Stress : Regulation of the Caulobacter crescentus cell cycle in response to environmental cues

    Author : Kristina Heinrich; Kristina Jonas; Emanuele Biondi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Caulobacter crescentus; bacteria; cell cycle; stress; filamentation; cell morphology; DNA replication; cell division; molekylär biovetenskap; Molecular Bioscience;

    Abstract : All organisms have to respond to environmental changes to maintain cellular and genome integrity. In particular, unicellular organisms like bacteria must be able to analyze their surroundings and rapidly adjust their growth mode and cell cycle program in response to environmental changes, such as changes in nutrient availability, temperature, osmolarity, or pH.

  4. 17. Exploring the Cell Cycle of Archaea

    Author : Magnus Lundgren; Rolf Bernander; William Margolin; Uppsala universitet; []
    Keywords : Microbiology; Archaea; Cell cycle; Replication; Mitosis; Cell division; Mikrobiologi;

    Abstract : Archaea is the third domain of life, discovered only thirty years ago. In a microscope archaea appear indistinguishable from bacteria, but they have been shown to be more closely related to eukaryotes than to bacteria. Especially central information processing is homologous to that of eukaryotes. READ MORE

  5. 18. Fluorescence Studies of Cell Division in Escherichia coli

    Author : Bill Söderström; Gunnar von Heijne; Jie Xiao; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; E. coli; Cell division; FtsZ; Fluorescence microscopy; FRAP; Biophysics; biofysik;

    Abstract : In Escherichia coli the cell division is carried out by a large dynamic protein complex called the divisome. The divisome assembles in a two-step manner starting with the localization of the eukaryotic tubulin homologue FtsZ to the midcell. Together with other early arriving proteins FtsZ form an intermediate structure called the Z-ring. READ MORE

  6. 19. Cytoskeletal filament systems : assembly, regulation, and interplay in mammalian cells

    Author : Mikael E Sellin; Martin Gullberg; Jeremy Thorner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell research; cellforskning;

    Abstract : The cell represents the basic unit of structure and function for all life. The interior of a eukaryotic cell is organized by an extensive array of protein filaments – collectively referred to as the cytoskeleton. These filaments serve diverse essential functions, e.g. READ MORE

  7. 20. Control of FtsZ-ring formation and cell division in Streptomyces venezuelae

    Author : Beer Sen; Klas Flärdh; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Streptomyces; SepIVA; SepF-like proteins; divisome; Z-ring assembly; Cooperativity; cell division; FtsZ;

    Abstract : Cell division is essential for all life forms. In bacteria, this fundamental process is precisely orchestrated by a protein, FtsZ, the ancestral homolog of eukaroytic tubulin. READ MORE
