  1. 1. Damage Segregation and Cellular Rejuvenation in Saccharomyces cerevisiae

    Författare :Sandra Malmgren Hill; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aging; protein damage; quality control; metacaspase; aggregates; segregation; vacuole;

    Sammanfattning : The process of aging is defined as a time-dependent decline in cellular functionality, and aging is thought to have evolved as organisms were optimized for reproduction, at the cost of an imperfect repair and maintenance system. As a consequence, different kinds of dysfunctional components and damage accumulate over time. LÄS MER

  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.

  4. 3. Significance of hydrolytic enzymes expressed during xylem cell death

    Författare :Benjamin Bollhöner; Hannele Tuominen; Moritz Nowack; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; Populus; xylem cell death; metacaspase; fiber; lateral root emergence; molekylärbiologi; Molecular Biology; Physiological Botany; fysiologisk botanik; molecular cell biology; molekylär cellbiologi;

    Sammanfattning : Xylem is an inherent feature of all vascular plants and functions in water transport and mechanical support. In order to efficiently transport water, xylem cells are reinforced by secondary walls before they undergo programmed cell death and their cell contents are removed by autolysis to create a hollow tube.
