Diseases of Rhododendron and Boxwood: Survey and Virulence of Phytophthora Root Rot and Management of Boxwood Blight with Systemic Fungicides

Creator:: Sacher, Gabriel
Abstract:: Diseases can be a substantial threat to woody plant production, a major industry in Oregon. Boxwood (Buxus spp.) and rhododendron (Rhododendron subgenus Rhododendron and Hymenanthes) represent the top two broadleaf evergreen woody plants by farmgate value in Oregon. Historically, Phytophthora root rot has been considered the most destructive disease of...

Community Ecology and Population Genomics of Rhizopogon in the Madrean Sky Island Archipelago

Creator:: Piña Páez, Carolina G.
Abstract:: Anthropogenic induced climate change is predicted to alter distribution of existing plant populations. As plants migrate over space and time, populations often fragment and contract, affecting basic elements of population dynamics (e.g., population size, gene flow, genetic diversity, etc.). Little is known, however, how these impacts on plant species will...

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...

Characterization of the transition to the progamic phase in Zea mays pollen

Creator:: Smyth, Johanna C.
Abstract:: The transition of mature pollen to the progamic phase represents an important step in the regulation of plant sexual reproduction. The progamic phase encompasses the initiation of pollen tube germination, growth of the pollen tube through the stigma (the silk in maize) and concludes with fertilization of the female gametophyte....

Pseudaleuria quinaultiana, a new genus and species of operculate ascomycete from the Olympic Peninsula

Creator:: Lusk-Newman, Demaris E.
Abstract:: Pseudaleuria quinaultiana gen. et sp. nova is described in English and Latin. P. quinaultiana is compared with Aleuria, Anthracobia Cheilymenia, Geopyxis, Humaria, lodophanus, Jafnea, Leucoscypha, Melastiza, Octospora, Pyronema, Scutellinia, Sphaerosporella, Tricharina, Morchella, Cookeina, Phillipsia, Pseudoplectania, Sarcoscypha, and Sarcosoma. Of these genera P. quinaultiana has hairs most similar to those found...

The effect of zinc limitation on the transcriptome of Pseudomonas protegens Pf-5

Creator:: Lim, Chee Kent, Hassan, Karl A., Penesyan, Anahit, Loper, Joyce E., and Paulsen, Ian T.
Abstract:: Zinc is an important nutrient but can be lacking in some soil environments, influencing the physiology of soil-dwelling bacteria. Hence, we studied the global effect of zinc limitation on the transcriptome of the rhizosphere biocontrol strain Pseudomonas protegens Pf-5 (formerly Pseudomonas fluorescens). We observed that the expression of the putative...

Abstract:: Despite a large and multifaceted effort to understand the vast landscape of phenotypic data, their current form inhibits productive data analysis. The lack of a community-wide, consensus-based, human- and machine-interpretable language for describing phenotypes and their genomic and environmental contexts is perhaps the most pressing scientific bottleneck to integration across...

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...

Emerging semantics to link phenotype and environment

Abstract:: Understanding the interplay between environmental conditions and phenotypes is a fundamental goal of biology. Unfortunately, data that include observations on phenotype and environment are highly heterogeneous and thus difficult to find and integrate. One approach that is likely to improve the status quo involves the use of ontologies to standardize...
