  • In vivo Reactions of Tetrazines Incorporated through Genetic Code Expansion

    Creator:
    Blizzard, Robert J.
    Abstract:
    The inverse electron demand Diels Alder reaction between tetrazines and strained alkenes is an exceptionally useful tool in functionalizing to biomolecules since it is orthogonal to the chemistry of most living systems and have exceptionally high rate constants. In particular reactions between strained trans-cyclooctenes (sTCO) and tetrazines can achieve second...

  • Developing Tools to Utilize the Oregon State University Woody Plant Collection and Establish a Campus Arboretum

    Creator:
    Blanchard, William D.
    Abstract:
    Oregon State University campus grounds have long been admired for their beauty and the diversity of over 65,000 individual woody plants that grace the 570 acres of campus. The woody plant collection has provided a living learning laboratory for the university and surrounding community for decades. The campus grounds include...

  • π-line reconstruction formulas in computed tomography

    Creator:
    Hass, Ryan Andrew
    Abstract:
    X-ray computed tomography is a noninvasive imaging modality capable of reconstructing exact density values of 3D objects. Computed tomography machines are deployed across the world to provide doctors with an image that reveals more detail than a standard x-ray image. We investigate algorithms based on exact computed tomography reconstruction formulas...

  • Hybridization between yellow starthistle (Centaurea solstitialis) and meadow knapweed (Centaurea x moncktonii)

    Creator:
    Miskella, John
    Abstract:
    Centaurea solstitialis L. (yellow starthistle) and C. × moncktonii Britt. (meadow knapweed) are members of the genus Centaurea in the Asteraceae family. Both species have become serious management concerns as invasive species in North America, often displacing native vegetation and costing land managers millions of dollars to eradicate. Seven plants...

  • Phenotyping Ornamental Plants: Case Studies in Fruit Quality Attributes from Vaccinium ovatum and Disease Resistance of Cotoneaster spp.

    Creator:
    Neill, Kristin E.
    Abstract:
    Landscape plants are highly diverse and nursery producers often grow thousands of taxa to satisfy the varied needs and aesthetic tastes of consumers. Related to this diversity, ornamental plant breeders must be nimble and diverse in their approach. Two seemingly disparate studies were conducted to investigate improving ornamental shrubs –...

  • Employing Genetic Code Expansion Tools to Elucidate Disease Mechanisms and Generate New Therapeutics

    Creator:
    Van Fossen, Elise M.
    Abstract:
    In biology, function and disease are closely intertwined, requiring the coordination of hundreds of intricate chemical reactions. Interdisciplinary cooperation between chemical and biological approaches is necessary to decipher the chemical links between physiological and pathological conditions. In this arena, the precision tools made possible with chemical biology can manipulate and...

  • Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

    Creator:
    Wang, Lu
    Abstract:
    Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

  • Defining the Role of Tyrosine Nitration in Biology with Genetic Code Expansion

    Creator:
    Porter, Joseph J.
    Abstract:
    The buildup of reactive oxygen species (ROS) and reactive nitrogen and oxygen species (RNS) is known as oxidative stress. Oxidative stress results in a wide variety of modification to biological macromolecules including nucleic acids, lipids, and proteins. For at least 30 years it has been known that high levels of...

  • Exploring the Limits of Ligation Rate and Specificity in Protein Immobilization Using the Genetically Encoded Tetrazine Ligation

    Creator:
    Bednar, Riley M.
    Abstract:
    Immobilized proteins are integral components of a number of important technologies, including the principal component of many biosensors, as functional coatings in various implants, as catalysts is industrial biosynthesis, and as the building blocks of next-generation nanotechnologies. Despite their ubiquity, relatively little is known about the processes that shape immobilized...

  • Structural Insights into Novel Sugar Phosphate Cyclases and Flavoenzymes

    Creator:
    Kean, Kelsey M.
    Abstract:
    The function of a protein is defined by its three-dimensional structure, and in understanding the three-dimensional structure of a protein, we gain an understanding of its function and mechanism. Protein structures, especially at high resolution, can provide detailed insights into many elements of enzyme function and catalysis – identifying residues...
