  1. 1. Programmed Cell Death in Xylem Development

    Författare :Laetitia Charleen Courtois-Moreau; Hannele Tuominen; Stefan Jansson; Christina Dixelius; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCD Programmed Cell Death ; Xylem; Apoptosis; Autophagy; Secondary Cell Walls; Microscopy; Microarrays; Comet Assay; TUNEL Assay; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : Concerns about climate changes and scarcity of fossil fuels are rising. Hence wood is becoming an attractive source of renewable energy and raw material and these new dimensions have prompted increasing interest in wood formation in trees, in both the scientific community and wider public.

  3. 2. Xylem cells cooperate in the control of lignification and cell death during plant vascular development

    Författare :Sacha Escamez; Hannele Tuominen; Andrew Groover; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Xylem; Arabidopsis; programmed cell death; tracheary element; xylem vessel; autophagy; metacaspase; lignin; secondary cell wall; chromatin; gene expression;

    Sammanfattning : The evolutionary success of land plants was fostered by the acquisition of the xylem vascular tissue which conducts water and minerals upwards from the roots. The xylem tissue of flowering plants is composed of three main types of cells: the sap-conducting tracheary elements (TE), the fibres which provide mechanical support and the parenchyma cells which provide metabolic support to the tissue.

    Sammanfattning : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. LÄS MER

  5. 4. Molecular mechanisms of cell death and cell clearance

    Författare :Katharina Klöditz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Programmed cell death (PCD) is a naturally occurring event in multicellular organisms. It is part of the development as well as ensuring tissue homeostasis and cellular turnover. LÄS MER

  7. 5. Who is killing whom? Hantaviruses vs programmed cell death

    Författare :Shawon Gupta; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hantaviruses belong to the Bunyaviridae family of negative stranded RNA viruses. They carry a tri-segmented genome and consist of four structural proteins. The four structural proteins are two glycoproteins Gn and Gc, a nucleocapsid (N) protein and an RNA-dependent RNA-polymerase. LÄS MER
