  • Endosperm morphogenesis in wheat (Triticum aestivum L.)

    Creator:
    Huber, Andrew Gail, 1944-
    Abstract:
    Wheat endosperm morphogenesis was studied by light microscopy during the entire growth period of anthesis to maturity. Four developmental stages have been described in this thesis: (1) double fertilization, (2) formation of the lower endosperm cells, (3) termination of nuclear divisions, and (4) initiation of protein bodies. The first manuscript...

  • Bacterioplankton in the Oregon upwelling system: distribution, cell-specific leucine incorporation, and diversity

    Creator:
    Longnecker, Krista
    Abstract:
    Marine bacterioplankton play an important role in global elemental cycles because they return carbon dioxide and nutrients to the biosphere as they reduce organic matter. Furthermore, marine bacterioplankton are not uniformly active, and subpopulations of the in situ community may be more or less active at any given time. Defining...

  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • Modeling protein structure at atomic resolution

    Creator:
    Berkholz, Donald S.
    Abstract:
    This thesis includes three studies involving different aspects of modeling protein structure. The first study illustrates the levels of insight available from atomic-resolution protein structures. The second study derives general trends of protein geometry from atomic-resolution structures and shows their implications for modeling. The third study creates a model of...

  • Canopy Ecology of Swiss Needle Cast in Young and Mature/Old-growth Douglas-fir (Pseudotsuga menziesii)

    Creator:
    Lan, Yung-Hsiang
    Abstract:
    Swiss needle cast (SNC) is a foliage disease of Douglas-fir caused by Nothophaeocryptopus gaeumannii, an Ascomycete fungus (Mycosphaerellaceae) that causes growth reductions in Douglas-fir plantations across the Pacific Northwest. Epidemiology of the fungus is generally well known in plantation trees, but the relationship between disease expression and foliage nutrition and...

  • Regulation of skeletal muscle protein degradation by u-calpain and development of a skeletal muscle-specific inducible expression system

    Creator:
    Xiao, Ying-Yi
    Abstract:
    The first goal of this study was to understand the role of u-calpain in skeletal muscle protein degradation in cultured muscle cells. Several strategies were developed to down-regulate endogenous u-calpain activity and m-calpain activity in rat myotubes. These included over-expression of antisense u-calpain (AnsL), dominant negative u-calpain (DN-u-CL), antisense 30K...

  • Gene Networks of the Skeletal Muscle Cell

    Creator:
    Singh, Arun J.
    Abstract:
    Skeletal muscle is the largest organ in the body by mass, comprising roughly 40% of total bodyweight in adults. It plays diverse and unique roles that include movement, locomotion, and support for posture and internal organs, among others. The structural foundation for all skeletal muscle in adults is formed early...

  • Oxidative stress and muscle dysfunction following anterior cruciate ligament surgery

    Creator:
    Barker, Tyler
    Abstract:
    Despite the advances in surgery, physical therapy, and pharmaceutical agents, muscle dysfunction (i.e., atrophy and weakness) continues to impair recovery from an anterior cruciate ligament (ACL) injury and surgery. Ischemia-reperfusion injury during surgery and the subsequent limb disuse are two events experienced by patients having ACL surgery. Oxidative stress and...

  • Relationships of ammonium and nitrate status with inflorescence necrosis in 'Pinot noir' grapevines

    Creator:
    Gu, Sanliang
    Abstract:
    Inflorescence necrosis (IN) is a recently described disorder in grapes characterized by partial or complete deterioration of the pedicel and rachis near bloom. Elevated levels of ammonium in the rachis are associated with the incidence of IN and hypothesized as the cause of the disorder. An incubation system with single-node...

  • Quorum-sensing-controlled public goods in Pseudomonas aeruginosa : regulation and application

    Creator:
    Mellbye, Brett L.
    Abstract:
    Cell-to-cell communication by chemical signals, termed quorum sensing (QS), is a common regulatory scheme in the microbial world. Pseudomonas aeruginosa¸ an opportunistic pathogen of burn wounds and cystic fibrosis lungs, uses QS to control the expression of hundreds of genes, particularly those necessary for population level benefits such as biofilm...
