  • Plant hormone-induced defense responses against Botrytis cinerea

    Creator:
    Akagi, Aya
    Abstract:
    Several plant hormones, including ethylene and jasmonates, are known to mediate responses against biotic and abiotic stress. The first and second objectives of this thesis were (i) to elucidate the role of ethylene in defense responses against Botrytis cinerea and specifically (ii) to determine the potential contribution of ethylene response...

  • Genetic resistance to white mold (Sclerotinia sclerotiorum (Lib.) De Bary) in scarlet runner beans (Phaseolus coccineus L.)

    Creator:
    Gilmore, Barbara S.
    Abstract:
    White mold, caused by Sclerotinia sclerotiorum (Lib.) De Bary, is a destructive yield-limiting disease of common bean (Phaseolus vulgaris L.). Genetic resistance to this pathogen is limited in common bean. Identification of high levels of partial physiological resistance in a genetically cross compatible species, Phaseolus coccineus, is advisable. The objectives...

  • Characterization, epidemiology, and ecology of a virus associated with black raspberry decline

    Creator:
    Halgren, Anne B.
    Abstract:
    The objective of this study was to characterize an unknown agent associated with decline in black raspberry (Rubus occidentalis) in Oregon. A virus was found consistently associated with decline symptoms of black raspberries and was named Black raspberry decline associated virus (BRDaV). Double stranded RNA extraction from BRDaV-infected black raspberry...
