  • Characterizing novel bacterial isolates that inhibit the growth of gall-forming phytopathogenic bacteria

    Creator:
    Belcher, Michael S.
    Abstract:
    Agrobacterium tumefaciens and Rhodococcus fascians are plant pathogenic bacteria that can induce crown and leafy galls on plants, respectively. Infection by these bacteria results in disfigured, unsellable plants, leading to significant economic losses to the nursery industry. A. tumefaciens and R. fascians are capable of infecting a broad range of...

  • The role of the actin cytoskeleton in plant/pathogen interactions

    Creator:
    Pena, Meesha and Chang, Jeff
    Abstract:
    As part of an HHMI funded research project, I showed that overexpression (OE) of actin (ACT2) in Arabidopsis thaliana alters the expression of genes involved in plant immunity. Others have previously shown that knockout (KO) mutants of actin depolymerizing factor 4 are affected in the same gene as ACT2-OE. For...

  • Development of a new molecular diagnostics tool for Agrobacterium tumefaciens

    Creator:
    Fuller, Skylar, Savory, Elizabeth, Weisberg, Alex, and Chang, Jeff
    Abstract:
    Agrobacterium tumefaciens causes the economically important plant disease, crown gall. These galls are the result of abnormal growth that manifests itself on either the root or the stem and can be devastating for the ornamental plant industry. Introduction of A. tumefaciens to a nursery can be highly detrimental and thus...

  • 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...

  • Alternative splicing in the obligate biotrophic oomycete pathogen, Pseudoperonospora cubensis

    Creator:
    Cumbie, Jason S.
    Abstract:
    Oomycetes are some of the most devastating pathogens, causing upwards of billions of dollars of damage each year to plants. They also diminish ecological diversity and health through the destruction of trees and shrubs. The genome sequence of Pseudoperonospora cubensis, an obligate plant pathogen and causative agent of downy mildew...

    Miller, Robert E.
    Abstract:
    The Teledyne Wah Chang facility is a manufacturer of the rare metal zirconium. The facility has been in constant production since 1956. In 1973 an attempt to utilize different sand ore sources from Nigeria and India in a new carbiding process, prior to chlorination, failed. The resulting byproducts of the...
