A Putative PAMP-Induced Peptide Family Member is Associated with Symptom Severity to the Necrotic Strain NTN of Potato Virus Y in Potato

Creator:: Combest, Max M.
Abstract:: Potato Virus Y (PVY) is an enduring problem for potato production worldwide. Potato varieties that resist the “ordinary” strain PVYO were developed by breeders, but in recent years, recombinant strains of PVY have been able to circumvent this strain-specific resistance and evade growers and seed certification officials by causing fewer...

Molecular Analysis of Environmental Water Samples as a Monitoring Method for the Fish Parasite Ichthyophthirius multifiliis

Creator:: Howell, Claire K.
Abstract:: Parasites are ubiquitous members of ecological communities, capable of contributing to the decline of vulnerable populations. Therefore, monitoring parasite level is a critical component for host management. Molecular tools, such as quantitative polymerase chain reaction (qPCR), can be valuable additions to monitoring protocols that assess parasitic disease risk to hosts....

Development of genetic resources for Rubus occidentalis from three segregating sources of resistance to Aphid Amphorophora agathonica

Creator:: Mulch, Christina M.
Abstract:: Black raspberry (Rubus occidentalis L.) is a US Pacific Northwest specialty crop prized for its unique flavor profile and nutritional attributes. A major obstacle for the raspberry industry is Black raspberry necrosis virus vectored by the large raspberry aphid (Amphorophora agathonica). Market expansion depends on production, which is currently hindered...

The Effect of Downed-trees on Harvesting Productivity and Costs in Beetle-killed Stands

Creator:: Kim, Yaejun
Abstract:: The mountain pine beetle has impacted over 5 million hectares of pine forests in the Rocky Mountains region in the United States. Although some beetle-killed stands are available for salvage harvesting, there are many uncertainties in harvesting beetle-killed stands including safety, costs, recoverable products and their values. These uncertainties impose...

Comparing Ectomycorrhizal Communities of Understory Giant Chinquapin (Chrysolepis chrysophylla) and Overstory Pinaceae Trees in a Mixed Conifer Forest in Central Oregon

Creator:: Longway, Lucas J.
Abstract:: Giant chinquapin (Chrysolepis chrysophylla) is an evergreen hardwood often found as a shrubby understory component of coniferous forests in the Pacific Northwest United States. Due to its ability to sprout quickly after disturbances such as fire and logging it is often viewed as a pest by forest managers. Like its...

Genome Resource Development for Advancement of Corylus avellana Breeding

Creator:: Talbot, Samuel Corcoran
Abstract:: The European hazelnut (Corylus avellana L.) is a tree nut crop that is important in Oregon, which produces 99% of the United States’ hazelnuts but only 5% of the world’s supply. In order to maintain this market share, farmers in Oregon need cultivars that produce high quality nuts, mature early,...

Problems of families with a diet-treated phenylketonuric child

Creator:: Mack, Marilyn Winnifred
Abstract:: The purpose of this study was to determine the possible problem areas in families with a diet-treated phenylketonuric child. Phenylketonuria is an inborn error of metabolism, which in the past caused mental retardation as well as behavioral disturbances. Initially the discovery of diet therapy eliminated the behavioral disturbances, but not...

Ethylene production from cultures of Cylindrocladium and from Cylindrocladium-infected azalea leaves

Creator:: Axelrood, Paige Ellen
Abstract:: Ethylene was produced by Cylindrocladium floridanum and C. scoparium in culture. Production was methionine dependent and maximal during the active growth phase of the fungus, beginning shortly after spore germination. More ethylene was produced sooner by C. floridanum than C. scoparium. Ethylene was produced by Cylindrocladium both from active mycelium...

Diet and nutrition of breeding canvasback and redhead ducks at Ruby Lake National Wildlife Refuge, Nevada

Creator:: Noyes, James Harry
Abstract:: Diet, nutrition, and foraging strategies of canvasbacks (Aythya valisineria) and redheads (A. americana) were studied by collecting actively feeding birds throughout the reproductive season in 1980 and 1981; samples of available foods were taken each time a bird was collected. Nutrient composition of the aggregate diet was determined for each...

Toxicity of some commonly used pesticides to Trioxys Pallidus and its establishment in filbert orchards of Willamette Valley

Creator:: Saeed, Mohammad
Abstract:: A parasitic wasp, Trioxys pallidus Haliday (Hymenoptera: Aphidiidae) was imported from Europe and initially released against the filbert aphid Mvzocallis coryli (Goetze) in hazelnut (filbert) orchards of the Willamette Valley, Oregon beginning in 1984. In the present study, I investigated the establishment rates of this parasitoid. A total of 13...
