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...

Effects of the insecticide dieldrin on benthic algae in laboratory streams

Creator:: Rose, Frederick Louis
Abstract:: The accumulation of dieldrin and its effects on species composition of benthic algal communities were studied in laboratory streams. Effects of dieldrin on photosynthetic and respiratory rates of the blue-green alga Phormidium retzii were determined using a Gilson Differential Respirometer. Dieldrin concentrations ranging from 0.05 to 7.0 ppb were maintained...

The disease cycle of side rot of pear, caused by Phialophora malorum

Creator:: Sugar, David
Abstract:: Potential sources of inoculum of Phialophora malorum were investigated. P. malorum was found to be a soil-borne fungus whose role as a postharvest pathogen of pear is dependent upon passive dispersal with infested soil. P. malorum survived in soil under a wide range of conditions, with greatest survival in cool,...

Science Takes Flight: Detection of Black Leg on Turnip Gray Mold on Hemp

Creator:: Bates, Taylor A.
Abstract:: Disease detection through traditional techniques such as scouting fields on foot, molecular assays, or morphological identification of plant pathogens is time consuming and costly. Disease diagnosis in the field can be extremely subjective, and largely depends on the experience and knowledge of pathogen identification and disease quantification. This thesis provides...

Investigations of Black Leg and Light Leaf Spot on Brassicaceae Hosts in Oregon

Creator:: Claassen, Briana J.
Abstract:: The Pacific Northwest is an internationally important region for the production of Brassica seed and other seed crops including grass seed. Oregon lawmakers mandated research into the co-existence of canola (Brassica napus) with other Brassica production in the Willamette Valley and House Bill 2427 was signed into law in 2013,...

Plastome phylogenomics in the genus Pinus using massively parallel sequencing technology

Creator:: Parks, Matthew Benjamin
Abstract:: This thesis summarizes work completed over the previous four years primarily focusing on chloroplast phylogenomic inquiry into the genus Pinus and related Pinaceae outgroups using next-generation sequencing on Illumina platforms. During the time of our work, Illumina sequence read lengths have essentially been limited to 25 to 100 base pairs,...

Reconciling Conflicting Phylogenies in the Origin of Sweet Potato and Dispersal to Polynesia

Creator:: Muñoz-Rodríguez, Pablo, Carruthers, Tom, Wood, John R.I., Williams, Bethany R.M., Weitemier, Kevin, Kronmiller, Brent, Ellis, David, Anglin, Noelle L., Longway, Lucas, Harris, Stephen A., Rausher, Mark D., Kelly, Steven, Liston, Aaron, and Scotland, Robert W.
Abstract:: The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. Our...

Genome Organization in the Ectomycorrhizal Truffle Rhizopogon vesiculosus

Creator:: Lu, Dabao Sun
Abstract:: Rhizopogon vesiculosus is a common ectomycorrhizal (EM) symbiont of Pseudotusga menziesii (Douglas-fir) in the coast range of the Pacific Northwest. The species has been studied for its systematics, genet size, population structure, and competitive ability in several field and experimental studies. This thesis seeks to provide a more thorough characterization...

Comparative Genomics of a Plant-Pathogenic Fungus, Pyrenophora tritici-repentis, Reveals Transduplication and the Impact of Repeat Elements on Pathogenicity and Population Divergence

Creator:: Manning, Viola A., Pandelova, Iovanna, Dhillon, Braham, Wilhelm, Larry J., Goodwin, Stephen B., Berlin, Aaron M., Figueroa, Melania, Freitag, Michael, Hane, James K., Henrissat, Bernard, Holman, Wade H., Kodira, Chinnappa D., Martin, Joel, Oliver, Richard P., Robbertse, Barbara, Schackwitz, Wendy, Schwartz, David C., Spatafora, Joseph W., Turgeon, B. Gillian, Yandava, Chandri, Young, Sarah, Zhou, Shiguo, Zeng, Qiandong, Grigoriev, Igor V., Ma, Li-Jun, and Ciuffetti, Lynda M.
Abstract:: Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins ( HST), which are recognized by their host in a genotype-specific...
