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

    Författare :Henrik Serk; Edouard Pesquet; Simon Hawkins; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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).

  3. 2. Functional ecology of ectomycorrhizal fungi : peroxidases, decomposition, spatial community patterns

    Författare :Inga Bödeker; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Boreal forest ecosystems constitute a globally important carbon (C) sink, due to accumulation of complex organic matter, persistent to decomposition. Nitrogen (N) is immobilized in these complex compounds and, thereby, unavailable to the plant community. LÄS MER

  4. 3. Targeting glutathione peroxidases : identifying environmental modulators, and screening for novel small molecule inhibitors

    Författare :Dorian M. Cheff; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Glutathione peroxidases (GPXs) are a family of selenoproteins that are critical regulators of reactive oxygen species (ROS) in the cell, specifically hydroperoxides like hydrogen peroxide (H2O2). ROS are important for normal cell signaling and are tightly controlled to promote cell growth, proliferation, and survival. LÄS MER

  5. 4. RECOMBINANT PEROXIDASES AND XYLANASES: I. Cloning and production of a peroxidase from horseradish II. Characterisation of functional domains of thermostable xylanases from Rhodothermus marinus

    Författare :Eva Bartonek Roxå; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amorphous cellulose; xylan; CBD; carbohydrate binding domains; insect cells; Baculovirus; catalytically active; recombinant horseradish peroxidase; HRP-n; PASC; beta-glucan; Biotechnology; Bioteknik;

    Sammanfattning : Part I: Plant peroxidases are useful in many areas of application e.g. as tracer enzymes for clinical applications and in biosensors as well as for industrial purposes like in waste water treatment and bleaching processes. A gene encoding a new, neutral horseradish peroxidase isoenzyme, HRP-n, was isolated. LÄS MER

  7. 5. Asexual embryogenesis in plants

    Författare :Boel Mårtensson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; two-phase partitioning; somatic embryogenesis; pollen embryogenesis; plasma membrane; peroxidase; Daucus carota isoperoxidase; Nicotiana tabacum; Ca2 transport; cell shape; calmodulin; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Sammanfattning : The capacity of somatic cells and pollen grains or microspores to undergo embryogenesis is an important property used in improvement and regeneration of plants. Furthermore, somatic embryogenesis as well as pollen embryogenesis show many similarities with zygotic embryogenesis and are, thus, good model systems. LÄS MER
