  • Genome-enabled investigation of the minimal growth requirements andphosphate metabolism for Pelagibacter marine bacteria

    Creator:
    Carini, Paul J.
    Abstract:
    Members of the SAR11 clade of heterotrophic α-proteobacteria are ubiquitous and abundant in the world's oceans where they are thought to play a pivotal role in the global carbon cycle. The first SAR11 bacterium cultivated in vitro, 'Candidatus Pelagibacter ubique' HTCC1062 (Ca. P. ubique), was isolated by dilution into sterile...

  • Pheromone Variation in Plethodontid Salamanders

    Creator:
    Chouinard, Adam J.
    Abstract:
    Plethodontid salamanders have served as an informative vertebrate system for studying the role of chemical signals in facilitating social and reproductive behaviors. Individuals produce complex mixtures of chemicals from multiple glandular regions. In total, these secretions convey a wide variety of information, and are important for numerous inter- and intraspecific...

  • Insights into Novel Non-Fumigant Nematicides: Physiological and Cellular Responses of Meloidogyne Incognita and Other Plant-Parasitic Nematodes

    Creator:
    Wram, Catherine L.
    Abstract:
    Plant-parasitic nematodes (PPN) pose a severe threat to crop production with the economic losses due to nematode parasitism in excessive of US$ 80 billion each year. Meloidogyne incognita, a globally distributed pest with a diverse host range, contributes significantly to this economic loss. The most reliable way to manage PPN...

  • Phylogeny and Evolution of Gall-Associated Plant Pathogenic Bacteria

    Creator:
    Davis, Edward W., II
    Abstract:
    Gall-associated phytopathogens have unique evolutionary histories that haveshaped both their modes of infection and genomic structures. Pathogenicity of the gall-associated plant pathogens of the Rhodococcus, Agrobacterium, and Rathayibactergenera is mediated by horizontally acquired virulence loci. The relative ease of gainand loss of the virulence loci has confounded accurate characterization of...

  • Unearthing the Cretaceous Diversification of Cornales

    Creator:
    Atkinson, Brian A.
    Abstract:
    The order Cornales (dogwoods) is the earliest diverging lineage within the most diverse group of flowering plants, the asterids (>80,000 species). Although molecular phylogenetics have significantly improved our understanding of cornalean systematics, early phylogenetic relationships remain uncertain due to an initial rapid radiation. The fossil record of Cornales is extensive...

  • 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,...
