Development of Diagnostic Assays for Race Differentiation of Podosphaera macularis

Creator:: Block, Mary H.
Abstract:: Hop powdery mildew (Podosphaera macularis) was confirmed in the Pacific Northwest in 1996. Before 2012, the most common race of P. macularis was able to infect plants that possessed powdery mildew resistance based on the R-genes Rb, R3, and R5. Post 2012, two additional races of P. macularis were discovered...

Identification and distribution of the mating-type locus and development of cleistothecia of Podosphaera macularis

Creator:: Wolfenbarger, Sierra N.
Abstract:: Podosphaera macularis, causal agent of hop powdery mildew, is known to produce cleistothecia (syn. chasmothecia) in eastern North America and Europe, but ascocarps are not reported from the Pacific Northwestern region of North America. Reasons for the apparent absence of cleistothecia in the Pacific Northwest are unknown. We established that...

Addressing the relationship between Pseudoperonospora cubensis and P. humuli using phylogenetic analyses and host specificity assays

Creator:: Mitchell, Melanie N.
Abstract:: The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...

The Influence of Nitrogen Fertility on Hop Quality, Pest Management, and the Stability of Biological Control

Creator:: Iskra, Anne E.
Abstract:: A multi-year field study was conducted in Oregon and Washington to evaluate the influence of nitrogen fertilization rate and timing on cone quality, nitrate accumulation in cones, severity of powdery mildew (caused by Podosphaera macularis), arthropod pests, and the stability of conservation biological control of the twospotted spider mite (Tetranychus...

A comparison of the effects of stretch duration and repetitions on hamstring extensibility

Creator:: Mende, Gent N.
Abstract:: The increase in tissue extensibility and joint range of motion through stretching has often been demonstrated. However, the existence of an optimal stretch duration has not been proven and the identification of an ideal number of repetitions of a stretch has received little attention in the literature. The purpose 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...
