Identification of Genetic Variation between Obligate Plant Pathogens Pseudoperonospora cubensis and P-humuli Using RNA Sequencing and Genotyping-By-Sequencing

Creator:: Summers, Carly F., Gulliford, Colwyn M., Carlson, Craig H., Lillis, Jacquelyn A., Carlson, Maryn O., Cadle-Davidson, Lance, Gent, David H., and Smart, Christine D.
Abstract:: RNA sequencing (RNA-seq) and genotyping-by-sequencing (GBS) were used for single nucleotide polymorphism (SNP) identification from two economically important obligate plant pathogens, Pseudoperonospora cubensis and P. humuli. Twenty isolates of P. cubensis and 19 isolates of P. humuli were genotyped using RNA-seq and GBS. Principle components analysis (PCA) of each data...

Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

Creator:: Stewart, Glenn H.
Abstract:: The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

Distribution and prediction of Swiss needle cast of Douglas-fir in coastal Oregon

Creator:: Rosso, Pablo H.
Abstract:: This study was directed to improve our understanding of the ecology of Swiss needle cast (SNC) of Douglas-fir, a disease that produces extensive damage to forests and plantation in the coastal region of Oregon and Washington. A disease prediction model for the coastal area of Oregon was built by establishing...

Dynamics of Zymoseptoria tritici Fungicide Resistance in the Willamette Valley of Oregon

Creator:: Hagerty, Christina H.
Abstract:: The development of resistance to multiple fungicide classes is currently limiting disease management options for many pathogens, while the discovery of new fungicide classes has become less frequent. To address this pressing issue, a three-part study with different layers of complexity, objectives, and experimental approaches was conducted using the model...

Location of prune dwarf and prunus necrotic ringspot viruses in sweet cherry pollen and fruit

Creator:: Kelley, Randall David
Abstract:: The location of prune dwarf virus (PDV) and Prunus necrotic ringspot virus (PNRSV) in pollen and seed from infected and healthy sweet cherry trees pollinated with infected pollen was investigated. Virus-like particles were observed in the cytoplasm of pollen grains from PDV-infected cherry trees using transmission electron microscopy. No particles...

Studies on canker in European filbert caused by Anisogramma anomala

Creator:: Postman, Joseph D.
Abstract:: Anisogramma anomala causes a stem canker of filberts, Corylus avellana. This disease became a threat to the main U.S. filbert growing region when it was introduced into the Pacific Northwest around 1968. Various methods of artificially inoculating filbert trees and seeds were explored. Less than 1% of potted filbert trees...

The detection of ilarvirus (subgroup B) by enzyme-linked immunosorbent assay

Creator:: McMorran, Jeffrey P.
Abstract:: The reliability and sensitivity of enzyme-linked immunosorbent assay (ELISA) in the detection of ilarvirus (isometric labile ringspot virus) subgroup B and prune dwarf virus (PDV) isolates in Prunus and Malus species has been well established. To use this technique in large scale virus indexing programs more information was required on...
