Expression of secondary metabolites following manipulations of the C:N ratio in spotted knapweed, Centaurea maculosa Lam.

Creator:: Brodhagen, Marion L.
Abstract:: Spotted knapweed, Centaurea maculosa Lam. (Compositae) is an extremely successful introduced weed species in the northwestern United States. Multiple factors may be responsible for its success, including chemical defense. Two different types of putative chemical defense agents are the focus of this thesis. The first is a bitter-tasting sesquiterpene lactone,...

Understanding Host-Pathogen Interactions in the Sphaerulina musiva-Populus Pathosystem

Creator:: Dunnell, Kelsey Liann
Abstract:: Host-parasite interactions between the pathogen, Sphaerulina musiva, and its host, Populus spp., were examined in a series of studies. In the first study, variation in resistance of Populus nigra from 7 locations in Europe was differentiated based on the parameters cankers per cm and disease severity score. The analysis evaluated...

A G-type Lectin Receptor-like Kinase Associated with Septoria Canker Resistance and Susceptibility Described using Multi-omics and Biotechnology

Creator:: Lenz, Ryan R.
Abstract:: Managers of forest and plantation ecosystems are encountering growing problems involving plant pathogens and the expanding geographic ranges of these pathogens. Historically unexposed stands are exceptionally vulnerable when a non-native pathogen is introduced because these pathogens can cause devastating disease in a host population that lacks co-evolved resistance mechanisms. One...

The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...

Ca. Nitrososphaera and Bradyrhizobium are inversely correlated and related to agricultural practices in long-term field experiments

Creator:: Zhalnina, Kateryna, de Quadros, Patricia D., Gano, Kelsey A., Davis-Richardson, Austin, Fagen, Jennie R., Brown, Christopher T., Giongo, Adriana, Drew, Jennifer C., Sayavedra-Soto, Luis A., Arp, Daniel J., Camargo, Flavio A. O., Daroub, Samira H., Clark, Ian M., McGrath, Steve P., Hirsch, Penny R., and Triplett, Eric W.
Abstract:: Agricultural land management, such as fertilization, liming, and tillage affects soil properties, including pH, organic matter content, nitrification rates, and the microbial community. Three different study sites were used to identify microorganisms that correlate with agricultural land use and to determine which factors regulate the relative abundance of the microbial...

Role of inoculum sources of Botrytis cinerea in the epidemiology of gray mold of snap beans

Creator:: Johnson, Kenneth Bjorn
Abstract:: Spore dispersal gradients and pod disease gradients from point inoculum sources of Botrytis cinerea were measured over time in two snap bean field experiments. Laboratory grown inoculum was placed at ground level in a 30 x 30 cm square at bloom initiation and removed at full bloom. Dispersal of inoculum,...

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...

New perspectives on evolutionary relationships within Pinus (Pinaceae) and within subsection Ponderosae (subgenus Pinus)

Creator:: Willyard, Ann Nachreiner
Abstract:: A fossil-calibrated phylogenetic framework based on exemplars from each of the four taxonomic sections within Pinus was created using multiple nuclear and chloroplast loci. Calibration at the well-defined subgeneric split within Pinus with either fossil leaves and cones (ca. 45 million years ago) or fossil wood (ca. 85 million years...
