The life history of Anisogramma anomala (Pk.) E. Müller (Diaporthaceae) and its pathological and epidemiological association with Corylus avellana L.

Creator:: Gottwald, Timothy Ross
Abstract:: Eastern Filbert Blight, caused by Anisogramma anomala (Peck) E. Miller, was first discovered in the Pacific Northwest in 1974. Orchard experiments suggest that the fungus completes its life cycle in two years. Infection takes place from mid-January to May, mainly through mite-galled-buds infested with an Eriophyid mite, Phytocoptella avellanae Nal....

The Influence of Nitrogen Fertility on Hop Quality, Pest Management, and the Stability of Biological Control

Creator:: Iskra, Anne E.
Abstract:: A multi-year field study was conducted in Oregon and Washington to evaluate the influence of nitrogen fertilization rate and timing on cone quality, nitrate accumulation in cones, severity of powdery mildew (caused by Podosphaera macularis), arthropod pests, and the stability of conservation biological control of the twospotted spider mite (Tetranychus...

Is Resistance Futile: Examining Fitness Costs Associated with QoI Resistance in E. necator

Creator:: Newbold, Chelsea L.
Abstract:: Quinone outside Inhibitor (QOI) fungicides are one of the most widely used fungicide classes (FRAC 11) in the world. This popularity is the result of their ability to effectively manage a wide array of economically important pathogen species on a broad range of crops. While having mostly preventative activity, some...

Seeing Genes: Multiscale Phenotyping Reveals Gene Functions in Maize Pollen

Creator:: Warman, Cedar D.
Abstract:: Plant sexual reproduction requires a broad array of molecular mechanisms to proceed successfully. Some of these mechanisms are well-studied, but our knowledge of them as a whole is fundamentally incomplete. Pollen tube growth is a key part of this process, facilitating the delivery of the sperm cells to the female...

Quantitative Trait Loci Associated with the Tocochromanol (Vitamin E) Pathway in Barley

Creator:: Graebner, Ryan C., Wise, Mitchell, Cuesta-Marcos, Alfonso, Geniza, Matthew, Blake, Tom, Blake, Victoria C., Butler, Joshua, Chao, Shiaoman, Hole, David J., Horsley, Rich, Jaiswal, Pankaj, Obert, Don, Smith, Kevin P., Ullrich, Steven, and Hayes, Patrick M.
Abstract:: The Genome-Wide Association Studies approach was used to detect Quantitative Trait Loci associated with tocochromanol concentrations using a panel of 1,466 barley accessions. All major tocochromanol types- α-, β-, δ-, γ-tocopherol and tocotrienol- were assayed. We found 13 single nucleotide polymorphisms associated with the concentration of one or more of...

The effects of a mutation within vitamin E biosynthesis upon the development and function of the photosynthetic apparatus

Creator:: Sicher, Richard Charles
Abstract:: A new photosystem-II mutant of the green alga Scenedesmus obliquus D₃, strain PS-28, has been shown to lack a-tocopherol (vitamin E). The photosynthetic activity of dark grown samples of PS-28 is about 20% of the wild-type control. Culturing the mutant at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic activity...

The culture and biochemical analysis of some estuarine phytoplankton species

Creator:: DeMort, Carole Lyle
Abstract:: The biochemical composition of ten species of estuarine phytoplankton was determined. Studies were made of their growth in various culture media and of their relative value as food for oyster larvae. Nine of the species were isolated from Yaquina Bay, Oregon. An attempt was made to select species which commonly...

Distribution and prediction of Swiss needle cast of Douglas-fir in coastal Oregon

Creator:: Rosso, Pablo H.
Abstract:: This study was directed to improve our understanding of the ecology of Swiss needle cast (SNC) of Douglas-fir, a disease that produces extensive damage to forests and plantation in the coastal region of Oregon and Washington. A disease prediction model for the coastal area of Oregon was built by establishing...

Meta-Analysis Reveals a Critical Period for Management of Powdery Mildew on Hop Cones

Creator:: Nelson, Mark E., Gent, David H., and Grove, Gary G.
Abstract:: Results of 28 field trials conducted over a 12-year period investigating management of hop powdery mildew caused by Podosphaera macularis were quantitatively summarized by meta-analysis to compare product efficacy and use patterns by mode of action as defined by Fungicide Resistance Action Committee (FRAC) groups. Availability of original observations enabled...
