  1. 1. Plant aquaporins

    Författare :Ingela Johansson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water deficit; calcium; plasma membrane; Plant biochemistry; channel; phosphorylation; Växtbiokemi;

    Sammanfattning : Aquaporins are integral membrane proteins that specifically transports water. In plants, aquaporins have been identified in the plasma membrane and in the vacuolar membrane. LÄS MER

  2. 2. Plant polyploidy and interactions with insect herbivores

    Författare :Leena Arvanitis; Johan Ehrlén; Christer Wiklund; John N. Thompson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; diversicifation; herbivory; host plant preference; plant galls; plant-insect interactions; plant polyploidy; selection; spatial variation; trait-fitness relationship; Terrestrial ecology; Terrestisk ekologi; Plant Ecology; växtekologi;

    Sammanfattning : Polyploidization has been suggested to be a common mechanism for plant speciation. Polyploidy is associated with changes in plant traits and altered habitat preference. LÄS MER

  3. 3. Context dependency of plant – animal interactions

    Författare :Malin A. E. König; Johan Ehrlén; Christer Wiklund; John Stinchcombe; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Anthocharis cardamines; attack intensity; Cardamine pratensis; cytotype; herbivory; larval fitness; oviposition; phenology; plant-animal interactions; plant resistance; plant tolerance; polyploidy; spatial variation; trait variation; Plant Ecology; växtekologi;

    Sammanfattning : The strength and direction of interactions between organisms vary spatially across the landscape. Traditionally, the focus has been on how trait variation affects the interactions between species. However, differences in abiotic and biotic environmental factors may also alter the distribution, phenology and behavior of the interacting species. LÄS MER

  5. 5. Calcium transporting ATPases in plant cells

    Författare :Malin Olbe; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Triticum aestivum; calcium; Brij 58; calmodulin; Ca2 signalling; inside-out; endoplasmic reticulum; plant; plasma membrane; proteolysis; P-type ATPase; spinach; Spinacea oleracea; trypsin; two-phase; wheat.; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. LÄS MER
