  1. 1. Cellular Control and Physiological Importance of Vascular Lignification

    Författare :Leonard Blaschek; Edouard Pesquet; Richard Sibout; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; växtfysiologi; Plant Physiology;

    Sammanfattning : Lignin is indispensable for vascular plants. It allows their cells to coalesce into gravity-defying giants, hardens them to withstand pressures and predators, and waterproofs them to allow the flow of water only where it is advantageous. LÄS MER

  2. 2. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways

    Författare :Daniela Geisler; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enzymology; Proteins; Kärlväxters fysiologi; Physiology of vascular plants; Växtekologi; Plant ecology; Växtbiokemi; Plant biochemistry; respiratory chain; plant mitochondria; nitrogen; NADPH dehydrogenase; NADH dehydrogenase; alternative oxidase; calcium; Proteiner; enzymologi; Bioenergetics; Bioenergetik; Lipids; steroids; membranes; Lipider; steroider; mebran;

    Sammanfattning : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. LÄS MER

  3. 3. Conifer embryology : a study of polar auxin transport and WOX transcription factors

    Författare :Joakim Palovaara; Inger Hakman; Wolfgang Werr; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Cell and Organism Biology; Cell- och organismbiologi;

    Sammanfattning : Plants, like animals, use endogenous signaling molecules to coordinate their own physiology and development. One such molecule in plants is the hormone auxin and recent research has implicated auxin and its polar transport, together with the WOX transcription factors, in regulating embryo patterning and development in angiosperms (flowering plants), the most diverse group of land plants.

  4. 4. Alternative NAD(P)H dehydrogenases in plant mitochondria - localisation, catalytic functions and physiological roles

    Författare :Agnieszka Michalecka; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kärlväxters fysiologi; Physiology of vascular plants; NAD P H dehydrogenase; light-dependence; electron transport chain; alamethicin; alternative oxidase;

    Sammanfattning : In addition to complex I, the plant mitochondrial electron transport chain possesses several alternative NAD(P)H dehydrogenases, not present in animals. These enzymes allow nonenergy-conserving electron transfer from cytoplasmic and matrix NAD(P)H to ubiquinone. LÄS MER

  5. 5. In vitro and in vivo approaches in the characterization of XTH gene products

    Författare :Nomchit Kaewthai; Harry Brumer; Jocelyn Rose; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabiodopsis thaliana; Hordeum vulgare; plant cell wall; xyloglucan; glycoside hydrolase family 16; xyloglucan endo-transglycosylase hydrolase gene family; xyloglucan endo-hydrolase; heterologous protein expression; Pichia pastoris; T-DNA insertion; in situ XET XEH assay; high-througput screening; Plant physiology; Växtfysiologi; Biochemistry; Biokemi; Functional genomics; Funktionsgenomik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : ABSTRACT The xyloglucan endo-transglycosylase/hydrolase (XTH) genes are found in all vascular and some nonvascular plants. The XTH genes encode proteins which comprise a subfamily of glycoside hydrolase (GH) family 16 in the Carbohydrate-Active enZYmes (CAZY) classification. LÄS MER
