  • Interactions of auxin with ethylene and gravity in regulating growth and development in tomato (Lycopersicon esculentum, Mill.)

    Creator:
    Madlung, Andreas
    Abstract:
    Plant growth, development, and environmental responsiveness are dependent on hormone-induced gene expression. This dissertation reports multiple interactions between the plant hormones auxin and ethylene and investigates their contribution to the gravitropic response, elongation growth, adventitious root formation, callus and tracheary element initiation and growth, and flower development. Four mutants of...

  • Dissecting induction of cell cleavage

    Creator:
    Alsop, G. Bradley
    Abstract:
    Cytokinesis separates replicated chromosomes and cytoplasm into two daughter cells. In animal cells, this is achieved by the formation of a cleavage furrow that bisects the mitotic (or meiotic) spindle. It is known that the mitotic apparatus defines the cell cleavage plane. However, it is not clear how the mitotic...

  • Onset of symbiosis in a cnidarian-dinoflagellate association

    Creator:
    deBoer, Melissa L.
    Abstract:
    Scleractinian corals, like many other cnidarians, engage in intracellular symbiosis with dinoflagellates belonging to the genus Symbiodinium. This association makes invaluable structural and energetic contributions to the marine environment and to the coral reef ecosystem in particular. While many aspects of the cnidarian-dinoflagellate relationship have been well studied, nothing is...

  • Temperature stress, gene expression, and innate immunity at the onset of cnidarian-dinoflagellate symbiosis

    Creator:
    Schnitzler, Christine E.
    Abstract:
    The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...

  • Toward making the invisible visible : studying science teaching self-efficacy beliefs

    Creator:
    Perkins, Catherine J.
    Abstract:
    This dissertation consists of two articles to be submitted for publication. The first, a literature review, makes visible common influences on science teaching self-efficacy beliefs and also points to potentially invisible validation concerns regarding the instrument used. The second investigates the participants' invisible science teaching self-efficacy beliefs and, through the...
