  • Nitrogen partitioning and remobilization in field-grown apple trees

    Creator:
    Khemira, Habib
    Abstract:
    Uptake and cycling of nitrogen (N) in mature trees are not well understood. Fertilizer-N uptake, partitioning, and use-efficiency were studied in standard strain 'Topred Delicious' and spur strain 'Redspur Delicious' mature apple trees {Malus domestica Borck) on 'Malling 7A' (M.7A) rootstocks. The treatments consisted of a ground application in spring,...

  • 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...
