  1. 1. New regulators of xylem lignification in arabidopsis

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

    Sammanfattning : 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. 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. Cell wall chemotyping for functional genomics : applications of pyrolysis-gas chromatography / mass spectrometry

    Författare :Lorenz Gerber; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The interest in lignocellulose as a sustainable resource for energy and materials has fueled research on biotechnology applications in tree breeding to improve biomass production and wood properties. An important aspect of this research is the basic understanding of gene function in wood formation, where analysis of wood chemistry and wood structure is of utmost importance. LÄS MER
