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...

Assessment of potato tuber blight caused by Phytophthora infestans

Creator:: Glass, Jenny Rebecca
Abstract:: Late blight, caused by Phytophthora infestans, is a devastating problem to potato production in many parts of the world. While the foliar phases of this disease are well characterized, tuber infection, leading to quality losses and disease perpetuation, is less well understood. Experiments were conducted during 1998 and 1999 in...

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...

Irrigation water and plant density effects on the epidemiology of aerial stem rot of potatoes

Creator:: Cappaert, Marlys R.
Abstract:: Field plots of cv. Russet Burbank potatoes from a single seedlot were established at four sites over two seasons (1985-86) in two locations in Oregon to determine the role of water-borne inoculum of Erwinia carotovora in plant infection. One site at each location was irrigated from a surface-water source and...

Soil water pressure and Verticillium dahliae interactions on potato

Creator:: Gaudreault, Suzanne M.
Abstract:: A greenhouse experiment was conducted in 1991 and in 1992 to determine the effect of soil water pressure on potato (cv Russet Burbank) plant growth and infection by Verticillium dahliae. Soil water pressures of -0.01, -0.03, -0.08, or -0.15 MPa were combined factorially with two inoculum concentrations, 0 or 10...

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,...

The effects of DMSO on wound periderm formation in potato tuber tissue

Creator:: Davidson, Roy M., 1939-
Abstract:: A study was conducted to determine the influence of DMSO (dimethyl sulfoxide) on suberization and wound periderm formation in cut potato tuber tissue, and to determine the effectiveness of DMSO as a potato seedpiece treatment for prevention of seedpiece decay in the field. The influences of tuber storage conditions, varieties,...

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...
