  • Influence of the Environment and Morphology on Physiological and Genomic Homeostasis in a Temperate Cnidarian-microbe Symbiosis

    Creator:
    Koch, Jack C.
    Abstract:
    Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...

  • Characterization of the pathogenicity and phylogeny of members of the Rhodococcus genus

    Creator:
    Creason, Allison L.
    Abstract:
    Plant pathogenic Rhodococcus species are persistent pathogens able to cause severe growth deformities on a large range of hosts. The most well studied species, R. fascians is predicted by current models to synthesize a mixture of cytokinins that act to directly perturb the hosts' hormone balances, which results in abnormal...

  • The role of innate immunity in cnidarian-dinoflagellate symbiosis

    Creator:
    Poole, Angela Z.
    Abstract:
    Cnidarians, such as corals and sea anemones serve as hosts to a variety of organisms including symbiotic dinoflagellates, bacteria, virus, and apicomplexans. As corals are vital to the health and productivity of the reef ecosystem it is important to understand how these organisms interact with each component of the holobiont....

  • Transcriptomic analysis using high-throughput sequencing and DNA microarrays

    Creator:
    Fox, Samuel E.
    Abstract:
    Transcriptomics and gene expression profiling enables the elucidation of the genetic response of an organism to various environmental cues. Transcriptomics enables the deciphering of differences between two closely related organisms to the same environment and in contrast, enables the elucidation of genetic responses of the same organism to different environmental...

  • Genome-enabled discovery and characterization of type III effector-encoding genes of plant symbiotic bacteria

    Creator:
    Kimbrel, Jeffrey A.
    Abstract:
    Symbiosis is the close and protracted interaction between organisms. The molecular interactions that occur during symbiosis are complex with multiple barriers that must be overcome. Many Gram-negative, host-associated bacteria use a type III secretion system to mediate associations with their eukaryotic hosts. This secretion system is a specialized apparatus for...

  • Effects of DNA mismatch repair inhibition in Arabidopsis thaliana

    Creator:
    Wilcox, Buck W. L.
    Abstract:
    Genomic instability underlies diseases of unregulated cell growth that result in cancers and developmental abnormalities in humans. Similar genome destabilizing mechanisms are used to create genetic variety in crops for use in breeding and trait development. Errors that occur during DNA replication may cause mutations if they are not corrected...

  • Generation of expression plasmids to study the function of the PRC2 subunit Suz12 in Fusarium graminearum

    Creator:
    Park, Catherine
    Abstract:
    The Polycomb Repressive Complex 2 (PRC2) catalyzes genome transcription repression through the methylation of lysine residue 27 in the amino terminal region of histone 3 (H3K27me1/2/3) [2], [7]. PRC2 is made up of three highly conserved core subunits: Kmt6, Eed, and Suz12. Accurate distribution of PRC2 is essential for proper...

  • Chlamydiae Enhance Self-Antigen Presentation in a Mechanism that is Dependent on Biosynthesis of Lipooligosaccharide

    Creator:
    Cram, Erik D.
    Abstract:
    Chlamydia is a genus of obligate intracellular bacteria that undergo a unique, biphasic developmental cycle. The infectious and metabolically inert Elementary Bodies (EBs) begin the cycle of infection by attaching and invading a host cells. Once inside, the EBs differentiate into the metabolically active, dividing Reticulate Bodies (RBs) within their...

  • Investigating Transcriptional Control of Specialized Gene Expression in Plants

    Creator:
    Fraser, Valerie N.
    Abstract:
    Specialized or secondary metabolism is a collection of pathways and small molecules that, while beneficial to an organism, are not strictly necessary for survival. Plants use secondary metabolites to, among other things, attract pollinators, defend against biotic and abiotic stressors, and form symbioses. Natural products from plants have seen an...

  • Prostate cancer prevention with broccoli : from cellular to human studies

    Creator:
    Clarke, John D.
    Abstract:
    Prostate cancer is the second leading cause of cancer related death in American men. Epidemiologic studies suggest that cruciferous vegetable intake may lower the risk for many cancers, including prostate and colon. Isothiocyanates (ITC) are phytochemicals derived from cruciferous vegetables such as broccoli, Brussels sprouts, cauliflower, and cabbage that may...
