  2. 1. Cellular Aspects of Lignin Biosynthesis in Xylem Vessels of Zinnia and Arabidopsis

    Author : Henrik Serk; Edouard Pesquet; Simon Hawkins; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin; tracheary elements; xylem wood; post-mortem lignification; non-cell autonomous process; xylem parenchyma; endoreplication; reactive oxygen species; laccases; peroxidases; molecular cell biology; molekylär cellbiologi;

    Abstract : Lignin is the second most abundant biopolymer on earth and is found in the wood (xylem) of vascular land plants. To transport the hydro-mineral sap, xylem forms specialized conduit cells, called tracheary elements (TEs), which are hollow dead cylinders reinforced with lateral secondary cell walls (SCW).

  4. 2. New regulators of xylem lignification in arabidopsis

    Author : Bernadette Sztojka; Hannele Tuominen; Simon Hawkins; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Xylem; lignin; Arabidopsis; secondary cell wall; transcriptional regulation; lignin-biosynthetic gene; S G lignin ratio;

    Abstract : The ability of land plants to grow upright, bear their own weight and withstand adverse environmental conditions is largely dependent on the secondary xylem tissues of the stem. The xylem cells acquire thick secondary cell walls which are composed of cellulose, hemicellulose and lignin. READ MORE
