Susceptibility of Hop Crown Buds to Powdery Mildew and its Relation to Perennation of Podosphaera macularis

Creator:: Gent, David H., Claassen, Briana J., Twomey, Megan C., Wolfenbarger, Sierra N., and Woods, Joanna L.
Abstract:: In the Pacific Northwestern United States, the hop powdery mildew fungus, Podosphaera macularis, survives overwintering periods in association with living host tissue because the ascigerious stage of the pathogen is not known to occur in this region. Field experiments were conducted over a 5-year period to describe the overwintering process...

Pre- and Postinfection Activity of Fungicides in Control of Hop Downy Mildew

Creator:: Gent, David H., Twomey, Megan C., Wolfenbarger, Sierra N., and Woods, Joanna L.
Abstract:: Optimum timing and use of fungicides for disease control are improved by an understanding of the characteristics of fungicide physical mode of action. Greenhouse and field experiments were conducted to quantify and model the duration of pre- and postinfection activity of fungicides most commonly used for control of hop downy...

Distribution and Characterization of Podosphaera macularis Virulent on Hop Cultivars Possessing R6-Based Resistance to Powdery Mildew

Creator:: Wolfenbarger, Sierra N., Massie, Stephen T., Ocamb, Cynthia, Eck, Emily B., Grove, Gary G., Nelson, Mark E., Probst, Claudia, Twomey, Megan C., and Gent, David H.
Abstract:: Host resistance, both quantitative and qualitative, is the preferred long-term approach for disease management in many pathosystems, including powdery mildew of hop (Podosphaera macularis). In 2012, an epidemic of powdery mildew occurred in Washington and Idaho on previously resistant cultivars whose resistance was putatively based on the gene designated R6....

Unproductive alternative splicing and nonsense mRNAs: A widespread phenomenon among plant circadian clock genes

Creator:: Filichkin, Sergei A. and Mockler, Todd C.
Abstract:: Background: Recent mapping of eukaryotic transcriptomes and spliceomes using massively parallel RNA sequencing (RNA-seq) has revealed that the extent of alternative splicing has been considerably underestimated. Evidence also suggests that many pre-mRNAs undergo unproductive alternative splicing resulting in incorporation of in-frame premature termination codons (PTCs). The destinies and potential functions...

Burial increases seed longevity of two Artemisia tridentata (Asteraceae) subspecies

Creator:: Wijayratne, Upekala C. and Pyke, David A.
Abstract:: • Premise of the study: Seed longevity and persistence in soil seed banks may be especially important for population persistence in ecosystems where opportunities for seedling establishment and disturbance are unpredictable. The fire regime, an important driver of population dynamics in sagebrush steppe ecosystems, has been altered by exotic annual...

Abstract:: We provide here a comparative genome analysis of ten strains within the Pseudomonas fluorescens group including seven new genomic sequences. These strains exhibit a diverse spectrum of traits involved in biological control and other multitrophic interactions with plants, microbes, and insects. Multilocus sequence analysis placed the strains in three sub-clades,...

The Personal Sequence Database: a suite of tools to create and maintain web-accessible sequence databases

Creator:: Givan, Scott A., Sullivan, Christopher M., and Carrington, James C.
Abstract:: Background: Large molecular sequence databases are fundamental resources for modern bioscientists. Whether for project-specific purposes or sharing data with colleagues, it is often advantageous to maintain smaller sequence databases. However, this is usually not an easy task for the average bench scientist. Results: We present the Personal Sequence Database (PSD),...

Identification of quantitative trait loci (QTL) for resistance to Fusarium crown rot (Fusarium pseudograminearum) in multiple assay environments in the Pacific Northwestern US

Creator:: Poole, G. J., Smiley, R. W., Paulitz, T. C., Walker, C. A., Carter, A. H., and See, D. R.
Abstract:: Fusarium crown rot (FCR), caused by and , reduces wheat ( L.) yields in the Pacific Northwest (PNW) of the US by as much as 35%. Resistance to FCR has not yet been discovered in currently grown PNW wheat cultivars. Several significant quantitative trait loci (QTL) for FCR resistance have...

Population Density and Phenology of Tetranychus urticae (Acari: Tetranychidae) in Hop is Linked to the Timing of Sulfur Applications

Creator:: Woods, J. L., Dreves, A. J., Fisher, Glenn C., James, David G., Wright, Larry C., and Gent, D. H.
Abstract:: The twospotted spider mite, Tetranychus urticae Koch, is a worldwide pest of numerous agronomic and horticultural plants. Sulfur fungicides are known to induce outbreaks of this pest on several crops, although mechanisms associated with sulfur-induced mite outbreaks are largely unknown. Studies were conducted during 2007–2009 in Oregon and Washington hop...
