  • Characterizing the Plant-Associated Symbionts, Rhodococcus and Agrobacterium

    Creator:
    Fuller, Skylar L.
    Abstract:
    Symbioses are a spectrum of interactions between organisms living in closeassociation. These intimate interactions range from mutualism, in which bothorganisms benefit, to parasitism, where one organism benefits at the expense ofthe other. Horizontal gene transfer is the acquisition of genes independent ofvertical transmission and demonstrably promotes the transition of bacteria...

  • 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...

  • 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...
