The Fungal Microbiome Associated with Grapevine Trunk Disease in Oregon Vineyards

Creator:: Zimmerman, Jessie
Abstract:: Grapevine Trunk Diseases (GTDs) are caused by a group of fungal pathogens that attack the xylem tissue of mature grapevines worldwide. In the past 30 years, their incidence has increased, both in emerging grape-producing regions, as well as those with an extended history of viticulture. In the same time span,...

Inferring Patterns and Processes of Emergence in Clonal Phytophthora Epidemics using Population Genomic Approaches

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

Toward a flexible and accurate approach to null network sampling

Creator:: Bright, Zachary A.
Abstract:: Null networks are a type of random graph that is favored for the analysis of a wide variety of real-world networks, including gene-regulatory networks, food webs, and species co-occurrence matrices. As a hypothesis-generating tool, null networks are invaluable because they can reveal network motifs and unusual large-scale properties of networks...

Silviculture Impacts and Population Genomics of Coniferiporia sulphurascens, the Causal Agent of Laminated Root Rot

Creator:: McMurtrey, Shawn
Abstract:: Within the Pacific Northwest, USA, root diseases of conifers are a major forest health concern. These diseases are primarily caused by basidiomycete fungi. These fungal associates play a vital role in carbon sequestration but also have a significant negative economic impact within the timber industry. As a result, research on...

Epidemic Dynamics of Sudden Oak Death in the Forests of Oregon

Creator:: Carson, Adam
Abstract:: Sudden Oak Death (SOD) is a forest disease caused by the oomycete pathogen Phytophthora ramorum, and infects trees in the Western United States and Europe. This generalist pathogen can infect over 130 species of plants, and causes rapid mortality in tree species in the Fagaceae. Sexual reproduction is thought to...

New Tools for Managing Erysiphe necator: Rapid Sampling Approaches and an Exploration of Grower Opinions and Perspectives towards Collective Action and Information Transfer

Creator:: Lowder, Sarah R.
Abstract:: The scale of pest and disease dispersal is often larger than the scale of individual farms. Therefore, an individual grower’s response to pests and diseases can affect and is affected by their surrounding growing region. Individual growers are also not isolated, and engage in various forms of information gathering, sharing,...

Permineralized Mesozoic Moss Gametophytes and their Implications for Bryophyte Evolution

Creator:: Bippus, Alexander C.
Abstract:: Mosses (Phylum Bryophyta) are widely considered to be among the most ancient groups of land plants (embryophytes) and they are the second most speciose embryophyte phylum with ~13,000 extant species. Despite their diversity and antiquity, mosses have a limited fossil record, which primarily consists of gametophytes entombed in Cenozoic amber....

Plant-Pollinator Interactions in a Changing World: Cryptic Specialization, Pollinator Movement, and Landscape Genetics of Pollinator-Dependent Plants

Creator:: Gannon, Dustin G.
Abstract:: Plant-pollinator mutualisms are one of the most prevalent and economically important mutualisms in nature. Like many other ecological systems, plant-pollinator communities are threatened by anthropogenic activity, both directly (e.g., habitat conversion and fragmentation) and indirectly (e.g., climate change). While we are aware of many of the activities that adversely impact...

Lichen Biomonitoring from Valley to Alpine in Central and Southern California

Creator:: Kovasi, Adrienne I.
Abstract:: In the mountains of central and southern California, high elevation wilderness areas lack epiphytic lichens that can be used to inform us about atmospheric deposition in multiple ways. Epiphytic lichens are capable of accumulating elements proportionally to the local atmospheric concentration, establishing them as commonly used biomonitor of key elements....

Host and Pathogen Genetics in the Sharp Eyespot Disease of Wheat

Creator:: Liu, Jiang
Abstract:: Wheat sharp eyespot (SES), caused by the soil-borne fungus Rhizoctonia cerealis is a common stem disease of wheat globally. The disease caused a severe and extensive epidemic throughout the Willamette Valley of Oregon in 2014 and has remained one of the most important wheat diseases in this region. However, litte...
