Kinetic Mechanism of the Hydrogen-Oxidizing Hydrogenase from Soybean Nodule Bacteroids

Creator:: Arp, Daniel J. and Burris, Robert H.
Abstract:: The kinetic mechanism of the unidirectional H2-oxidizing hydrogenase from soybean nodule bacteroids has been investigated with highly purified enzyme. Measurements of the K, for H2 vary from 0.97 to 2.6 pM, and the K,,, for methylene blue varies from 6 to 17 pM. With H2 and methylene blue as substrates,...

Improbability mapping: a metric for satellite-detection of submarine volcanic eruptions

Creator:: O'Malley, Robert T., Behrenfeld, Michael J., Westberry, Toby K., Milligan, Allen J., Reese, Douglas C., and Halsey, Kimberly H.
Abstract:: Submarine volcanic eruptions can result in both real and apparent changes in marine algal communities, e.g., increases in phytoplankton biomass and/or growth rates that can cover thousands of square kilometers. Satellite ocean color monitoring detects these changes as increases in chlorophyll and particulate backscattering. Detailed, high resolution analysis is needed...

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...

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...

The Plant Actin Cytoskeleton Responds to Signals from Microbe-Associated Molecular Patterns

Creator:: Henty-Ridilla, Jessica L., Shimono, Masaki, Li, Jiejie, Chang, Jeff H., Day, Brad, and Staiger, Christopher J.
Abstract:: Plants are constantly exposed to a large and diverse array of microbes; however, most plants are immune to the majority of potential invaders and susceptible to only a small subset of pathogens. The cytoskeleton comprises a dynamic intracellular framework that responds rapidly to biotic stresses and supports numerous fundamental cellular...

Mutualistic Co-evolution of Type III Effector Genes in Sinorhizobium fredii and Bradyrhizobium japonicum

Creator:: Kimbrel, Jeffrey A., Thomas, William J., Jiang, Yuan, Creason, Allison L., Thireault, Caitlin A., Sachs, Joel L., and Chang, Jeff H.
Abstract:: Two diametric paradigms have been proposed to model the molecular co-evolution of microbial mutualists and their eukaryotic hosts. In one, mutualist and host exhibit an antagonistic arms race and each partner evolves rapidly to maximize their own fitness from the interaction at potential expense of the other. In the opposing...

Sclerotinia Wilt of Hop (Humulus lupulus) Caused by Sclerotinia sclerotiorum in the Pacific Northwest United States

Creator:: Kropf, S. M., Putnam, M. L., Serdani, M., Twomey, M. C., Woods, J. L., and Gent, D. H.
Abstract:: In June 2009, wilted hop bines were observed in a yard in Marion County, OR. The wilt was associated with a stem rot that occurred ∽1 m from the ground near the point where bines are tied together for horticultural purposes. Samples of affected stems were submitted to the Oregon...

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...

Regional to global assessments of phytoplankton dynamics from the SeaWiFS mission

G., and Yoder, J. A.
Abstract:: Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean ecosystems. Changes in the surface chlorophyll concentration, the primary...

Computational and analytical framework for small RNA profiling by high-throughput sequencing

Creator:: Fahlgren, Noah, Sullivan, Christopher M., Kasschau, Krisitin D., Chapman, Elisabeth J., Cumbie, Jason S., Montgomery, Taiowa A., Gilbert, Sunny D., Dasenko, Mark, Backman, Tyler W. H., Givan, Scott A., and Carrington, James C.
Abstract:: The advent of high-throughput sequencing (HTS) methods has enabled direct approaches to quantitatively profile small RNA populations. However, these methods have been limited by several factors, including representational artifacts and lack of established statistical methods of analysis. Furthermore, massive HTS data sets present new problems related to data processing and...
