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...

Successional changes associated with benthic assemblages in experimental streams

Creator:: Busch, David E.
Abstract:: Experimental streams constructed by the Weyerhaeuser Company, Tacoma, Washington, at Kalama Springs, Washington, were used to observe successional changes in the benthos. Community changes were observed relative to experimental manipulations of light intensity and nitrate concentration in two experiments. The development of benthic assemblages was followed for 150 days after...

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...

Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:: David, Nicholas L.
Abstract:: Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...

The effects of native plants on non-native plant abundance in a restoration setting : differences among native species and the predictive ability of species traits

Creator:: Goodridge, Jennifer M.
Abstract:: Reducing the cover of non-native species is one of the challenges of ecosystem restoration. The goal of this study is to identify native species traits that will increase native species cover and reduce non-native species cover in the first growing season at upland and wetland prairie restoration sites. Native and...

Stand structures of Oregon white oak (Quercus garryana) woodlands and their relationships to the environment in southwestern Oregon

Creator:: Gilligan, Laurie A.
Abstract:: Large areas of non-coniferous communities in southwestern Oregon are thinned to reduce fire hazard and accomplish ecosystem restoration, under the assumption that current fuel loads are unnaturally high. Although Oregon white oak (Quercus garryana) woodlands are a characteristic landscape component in this region, little is known about their current or...

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...

Distributional patterns and taxonomic structure of diatom assemblages in Netarts Bay, Oregon

Creator:: Whiting, Mark Carlos
Abstract:: Epiphytic, planktonic and benthic diatom assemblages were investigated in Netarts Bay, Oregon. Samples were collected for a one-year period from February 1980 to March 1981. A planktonic flora was observed only during periods of offshore enrichment when marine neritic species were abundant and were transported into the bay by tidal...

Enhancement of biological control for postharvest diseases of pear

Creator:: Benbow, Jesse M.
Abstract:: Yeast biocontrol agents that were applied to 'Bose' and 'Anjou' pears in the field up to three weeks prior to harvest were found to survive on the fruit at high population levels on both pear varieties. Cryptococcus infirmo-miniatus, Cryptococcus laurentii, and Rhodotorula glutinis maintained populations averaging 5 x 10⁶ cfu/fruit...
