Yosemite region nitrogen deposition and patterns in the composition of lichen communities

Creator:: Hutten, Martin
Abstract:: This dissertation describes patterns in epiphytic macrolichen community composition along a nitrogen deposition gradient in the Yosemite region of the Sierra Nevada in California. This region is part of the largest federal air quality Class 1 designated air-shed in the western United States, covering the entire crest of the Sierra...

Yield responses of invasive grasses to carbon doses

Creator:: Brunson, Jessi L.
Abstract:: The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...

Within-population genetic structure differs between two sympatric sister-species of ectomycorrhizal fungi, Rhizopogon vinicolor and R. vesiculosus

Creator:: Dunham, Susie M., Mujic, Alija Bajro, Spatafora, Joseph W., and Kretzer, Annette M.
Abstract:: Using spatial autocorrelation analysis, we examined the within-population genetic structure of Rhizopogon vinicolor and R. vesiculosus, two hypogeous ectomycorrhizal (EM) species that are sympatric sister taxa known to differ in their clonal structure. We collected 121 sporocarps and 482 tuberculate EM of both species from a 20 ha forest stand...

Wind farm potential is higher in prime habitat for uncommon soil crust lichens

Creator:: Root, Heather T., McCune, Myrica, and McCune, Bruce
Abstract:: Introduction: Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi are associated with fine-textured soils along rivers of the Columbia Basin. A. schleicheri and R. diploschistidina indicate late-successional habitat and may serve as...

Why pest plant control and native plant establishment failed : a restoration autopsy

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., Clark, Deborah Louise, 1950-, and Wilson, Mark G.
Abstract:: Explaining restoration failure can be as important as touting success. We used a series of studies to understand the failure of techniques commonly used to restore wetland prairies in the Willamette Valley of western Oregon. Burning, fallowing, and solarization (covering tilled plots with plastic sheeting to heat the soil) had...

Whole-Plant Growth Stage Ontology for Angiosperms and Its Application in Plant Biology

Creator:: Pujar, Anuradha, Jaiswal, Pankaj, Kellogg, Elizabeth A., Ilic, Katica, Vincent, Leszek, Avraham, Shulamit, Stevens, Peter, Zapata, Felipe, Reiser, Leonore, Rhee, Seung Y., Sachs, Martin M., Schaeffer, Mary, Stein, Lincoln, Ware, Doreen, and McCouch, Susan
Abstract:: Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process. The terms describing these developmental stages record the morphological appearance of the plant at a specific point in its life cycle. The widely differing morphology of plant species consequently gave rise to heterogeneous vocabularies describing growth...

Water deficit stress effects on bacterial ring rot of potato caused by Clavibacter michiganensis subsp. sepedonicus

Creator:: Crabtree, Kristine L.
Abstract:: Population size of Clavibacter michiganensis subsp. sepedonicus in potato cv Russet Burbank and plant response as affected by drought were assessed in a greenhouse experiment. Water deficit stress and no stress treatments, and inoculum densities of 0 or 2 X 10⁷ cfu C. m. sepedonicus/seed piece were arranged factorially. Stem...

Vitamin B1 content in potato: effect of genotype, tuber enlargement, and storage, and estimation of stability and broad-sense heritability

Creator:: Goyer, Aymeric and Haynes, Kathleen G.
Abstract:: Thiamine pyrophosphate (vitamin B1) is an essential nutrient in the human diet, and is often referred as the energy vitamin. Potato contains modest amounts of thiamine. However, the genetic variation of thiamine concentrations in potato has never been investigated. In this study, we determined thiamine concentrations in freshly-harvested unpeeled tubers...

Virus-Derived Gene Expression and RNA Interference Vector for Grapevine

Creator:: Kurth, Elizabeth G., Peremyslov, Valera V., Prokhnevsky, Alexey I., Kasschau, Kristin D., Miller, Marilyn, Carrington, James C., and Dolja, Valerian V.
Abstract:: The improvement of the agricultural and wine-making qualities of the grapevine (Vitis vinifera) is hampered by adherence to traditional varieties, the recalcitrance of this plant to genetic modifications, and public resistance to genetically modified organism (GMO) technologies. To address these challenges, we developed an RNA virus-based vector for the introduction...

Viability and infective potential of Phytophthora pini zoospores in a recirculating irrigation system

Creator:: Shay, Sarah D.
Abstract:: Phytophthora pini Leonian, recently re-established from P. citricola I, is a pathogen with a wide range of forest and nursery hosts. It causes foliar infections in horticultural nurseries in Oregon, where recirculating irrigation systems are common. Increased use of recirculating irrigation systems may contribute to disease caused by waterborne plant...
