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

    Author : Benjamin Bollhöner; Hannele Tuominen; Moritz Nowack; Umeå universitet; []
    Keywords : 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;

    Abstract : 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.
