  2. 16. Natural variation in cold adaptation and freezing tolerance in Arabidopsis thaliana

    Author : Antoine Bos; Pär Ingvarsson; Hans Stenøien; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; cold acclimation; freezing tolerance; flowering time; latitudinal clines; genetic variation; evolutionary genetics; Molecular biology; Molekylärbiologi;

    Abstract : Plants have spread to almost everywhere in the world. As they disperse, they meet many different environments to which they may be able to adapt. For a plant species to adapt to a new environment, genetic variation is needed. The individuals differ from each other in their genetic composition, which often means differences in phenotypes.

  4. 17. Phenotypic Plasticity and Adaptation Potential to Salinity in Early Life Stages of the Tunicate, Ciona intestinalis spB

    Author : Elin Renborg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transgenerational acclimation; Environmental variation; Tolerance range; Marine invertebrate; Quantitative genetics; Genetic structure; Local adaptation; Sexual selection; Gamete compatibility; Relatedness; Inbreeding; Heritability; Maternal effects;

    Abstract : Species respond to environmental heterogeneity through a variety of mechanisms such as plasticity, genetic adaptation and phenotypic buffering. Determining how gene flow, scale of environmental heterogeneity and trait heritability influence these responses is important for understanding how these different mechanisms arise, which is a central task in the field of evolutionary biology.

    Abstract : Plants and other green organisms harvest sunlight by green chlorophyll pigments and covertit to chemical energy (sugars) and oxygen in a process called photosynthesis providing the foundation for life on Earth. Although it is unanimously believed that oceanic phytoplanktons are the main contributors to the global photosynthesis, the contribution of coniferous boreal forests distributed across vast regions of the northern hemisphere cannot be undermined.

  7. 20. Regulatory proteolysis of higher plant thylakoid membranes : the significance of protein degradation in light acclimation of the photosynthetic apparatus

    Author : Marika Lindahl; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Although the acclimation of plants to light condition has been known and extensively described for many years the underlying mechanisms have remained largely unsolved. In this thesis I present new experimental data and a model for the mechanism behind acclimation of mature higher plants to increased light intensities. READ MORE
