Pathways of infection of Phytophthora ramorum in rhododendron

Creator:: Lewis, Carrie D.
Abstract:: Phytophthora ramorum, a plant pathogen, is the cause of sudden oak death and ramorum blight and shoot die-back. It has a wide host range including many native forest species and common nursery plants. The lack of knowledge regarding infection biology of P. ramorum limits our understanding of its ecology and...

Occurrence, transmission, and properties of strains of cucumber mosaic virus that are seed-transmitted in Phaseolus vulgaris

Creator:: Davis, Robert Francis
Abstract:: A survey of major bean (Phaseolus vulgaris) breeding programs and seed producing areas in Idaho, Washington, and Oregon was conducted to determine the occurrence of cucumber mosaic virus (CMV), recently reported to be seedborne in beans. Some 259 plants, sampled from breeding lines of diverse germplasm, were found by enzyme-linked...

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...

A method of improving power system transient stability using controllable parameters

Creator:: Mittelstadt, William Andrew
Abstract:: Controllable parameters in a power system include generator terminal voltage, generator input power and network admittances. These parameters can be controlled to damp mechanical rotor oscillation in the generators and thereby improve system transient stability. Explicit equations are derived in this thesis for the control of these parameters to introduce...

Effects of Tetranychus urticae Koch feeding injury on physiological processes in Mentha piperita L.

Creator:: DeAngelis, Jack D.
Abstract:: Studies were conducted to examine the effects of feeding injury by the twospotted spider mite (Tetranychus urticae Koch) on physiological processes of its host plant, peppermint (Mentha piperita L.). Aspects of mite-induced host plant physiological stress that were studied included: 1) effects of injury on plant-water relations; 2) photosynthesis and...

Detection and transmission of Mycobacterium marinum and Mycobacterium chelonae in zebrafish (Danio rerio)

Creator:: Peterson, Tracy Shawn
Abstract:: Mycobacteriosis is a common disease of laboratory zebrafish (Danio rerio). Different infection patterns occur in zebrafish depending on mycobacterial species. Mycobacterium marinum and M. haemophilum produce virulent infections associated with high mortality, whereas M. chelonae is more wide spread and not associated with high mortality. Identification of mycobacterial infections to...

Pseudoloma neurophilia : progression of infection and transmission characteristics of a microsporidian parasite in a model vertebrate, Danio rerio

Creator:: Sanders, Justin L.
Abstract:: The microsporidian parasite, Pseudoloma neurophilia, is the most commonly diagnosed infectious disease in laboratory populations of the zebrafish, Danio rerio. Infections by P. neurophilia are generally subclinical, however, they can become acute either incidentally or due to experimental immune suppression. Non-protocol induced variation can confound results in laboratory experiments using...
