  1. 26. Energy balance during active carbon uptake and at excess irradiance in three marine macrophytes

    Författare :Herman Carr; Mats Björk; Lennart Axelsson; Félix López Figueroa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi;

    Sammanfattning : The marine environment is an important habitat where many processes occur that affect life conditions on earth. Macrophytes and planktonic oxygen evolvers are an essential component for almost all marine life forms and have developed in an environment that differs largely from the terrestrial habitats.

  3. 27. Mechanisms and genes controlling the signalling network for biotic and abiotic stress defences in Arabidopsis thaliana (L.) Heyhn : Functional cross-talk between photo-produced reactive oxygen species, photosynthesis and plant disease defence responses

    Författare :Christine Chi-Chen Chang; Stanislaw Karpinski; Christine Foyer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reactive oxygen species; Arabidopsis thaliana; signalling work; biotic stress; abiotic stress; Plant physiology; Växtfysiologi;

    Sammanfattning : Excess excitation energy, mechanical injury and defence against pathogens, each trigger rapid production of reactive oxygen species (ROS) in Arabidopsis thaliana leaves. ROS, such as hydrogen peroxide (H2O2), are required for the induction of systemic acquired acclimation and may lead to redox changes in photosynthetic electron transport (PET). LÄS MER

  4. 28. Analysis of sterol metabolism in the pathogenic oomycetes Saprolegnia parasitica and Phytophthora infestans

    Författare :Paul Dahlin; Vincent Bulone; Lisbeth Jonsson; Katharina Pawlowski; Lauren Mckee; Sophia Ekengren; Folke Sitbon; Steven Kelly; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant Physiology; växtfysiologi;

    Sammanfattning : The primary objective of this thesis was to investigate the sterol metabolism of two pathogenic oomycetes, specifically the processes of sterol synthesis and sterol acquisition in the fish pathogen Saprolegnia parasitica (Saprolegniales) and the plant pathogen Phytophthora infestans (Peronosporales). Furthermore, the effects of steroidal glycoalkaloids from Solanaceous plants, on P. LÄS MER

  5. 29. Phosphorylation in State Transition : Less cause more effect

    Författare :Jakob Damkjaer; Jansson Stefan; Eva-Mari Aro; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; Photoacclimation; State Transtion; LHCII Phosphorylation; Lhcb3; Lhcb6; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Study of the Arabidopsis thaliana knockout mutant lacking Lhcb3 (koLhcb3) have revealed a close similarity to the wild type plants. Growth rate, NPQ, qP, Φ(PSII), circular dichroism spectra, pigment composition and content of LCHII trimers have been found to be unaffected by this mutation. LÄS MER
