Development of Quantitative PCR Assays to Aid in Root-knot Nematode (Meloidogyne spp.) Diagnostics and Resistance Breeding Efforts in the Pacific Northwest

Creator:: Soule, Michelle L.
Abstract:: In the Pacific Northwest (PNW), the two most common root-knot nematodes are Meloidogyne hapla and Meloidogyne chitwoodi. These nematodes can infect a wide variety of crops and can cause significant losses. Currently, it is common for the field of nematology to use labor-intensive microscopy to identify plant-parasitic nematodes based on...

A Putative PAMP-Induced Peptide Family Member is Associated with Symptom Severity to the Necrotic Strain NTN of Potato Virus Y in Potato

Creator:: Combest, Max M.
Abstract:: Potato Virus Y (PVY) is an enduring problem for potato production worldwide. Potato varieties that resist the “ordinary” strain PVYO were developed by breeders, but in recent years, recombinant strains of PVY have been able to circumvent this strain-specific resistance and evade growers and seed certification officials by causing fewer...

Diversity and Impact of Soft Rot Pathogens of Potato in the Columbia Basin

Creator:: Brazil, Jessie A.
Abstract:: Bacterial soft rot of potato (Solanum tuberosum), caused by Pectobacterium and Dickeya species, is among the most common and destructive potato diseases in the United States. These pathogens cause a variety of vascular wilts, and in potato cause a disease complex that includes tuber soft rot, blackleg, aerial stem rot,...

Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:: David, Nicholas L.
Abstract:: Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...

Scratching the Surface of the Potato Geocaulosphere: Characterizing the Microbiome of Seed Tuber Tare Soil and its Impact on the Rhizosphere Microbiome

Creator:: Delventhal, Kayla D.
Abstract:: For tuberizing crops like potato (Solanum tuberosum), the geocaulosphere, or the zone of soil in contact with and influenced by the tuber, is a distinct sphere of microbial life and represents an important interface between the potato crop and the soil environment. Upon potato harvest, specific geocaulosphere soil called tare...

Seedborne Phytophthora infestans : effect of pathogen clonal lineage and potato cultivar on seed transmission of late blight and plant growth responses

Creator:: Partipilo, Heather M.
Abstract:: Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission rate across potato cultivars was 0.5 and 2.4% with US-8, and 0.8 and 1.0% with US-11 in 1999...

Improving Best Management Practices for Potato Production in the Columbia Basin : An Evaluation of Essential Oils for Control of Verticillium Wilt and the Fate of Chloride in the System

Creator:: Light, Sarah Elizabeth
Abstract:: Although the potato (Solanum tuberosum L.) is a global crop, few growing regions rival the high yields of the Columbia Basin of Eastern Oregon and Washington. Two research projects were conducted in Hermiston, OR to contribute to best management practices for the region. The first project evaluated the efficacy of...

Spatiotemporal Assessment of Crop Histories in the Pacific Northwest

Creator:: Kumbhakar, Ishika G.
Abstract:: The cultivated potato (Solanum tuberosum) is one of the most important food crops in the United States, as well as globally. As demand rises, growers in the Pacific Northwest are revisiting their crop management strategies to determine whether there are additional ways to enhance crop productivity while managing plant and...

Development and Application of Tools for Genetic Analysis of Clonal Populations

Creator:: Kamvar, Zhian N.
Abstract:: Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...

Phytosanitation of Douglas-fir (Pseudotsuga menziesii) logs to mitigate the risk of artificially disseminating Phytophthora ramorum within the global trade of timber

Creator:: Hulbert, Joseph M.
Abstract:: Phytophthora ramorum is a plant pathogen that was accidentally introduced to the United States. This invasive microorganism has killed over a million trees in California and Oregon, and continues to spread to new areas. Diseased areas have been nationally quarantined to prevent further spread and more than ninety countries include...
