Quantitative Trait Loci Associated with the Tocochromanol (Vitamin E) Pathway in Barley

Creator:: Graebner, Ryan C., Wise, Mitchell, Cuesta-Marcos, Alfonso, Geniza, Matthew, Blake, Tom, Blake, Victoria C., Butler, Joshua, Chao, Shiaoman, Hole, David J., Horsley, Rich, Jaiswal, Pankaj, Obert, Don, Smith, Kevin P., Ullrich, Steven, and Hayes, Patrick M.
Abstract:: The Genome-Wide Association Studies approach was used to detect Quantitative Trait Loci associated with tocochromanol concentrations using a panel of 1,466 barley accessions. All major tocochromanol types- α-, β-, δ-, γ-tocopherol and tocotrienol- were assayed. We found 13 single nucleotide polymorphisms associated with the concentration of one or more of...

Phytophthora ramorum colonizes tanoak xylem and is associated with reduced stem water transport

Creator:: Parke, J. L., Oh, E., Voelker, S., Hansen, E. M., Buckles, G., and Lachenbruch, Barbara
Abstract:: Isolation, detection with diagnostic polymerase chain reaction (PCR), and microscopy demonstrated the presence of Phytophthora ramorum in the sapwood of mature, naturally infected tanoak (Lithocarpus densiflorus) trees. The pathogen was strongly associated with discolored sapwood (P < 0.001), and was recovered or detected from 83% of discolored sapwood tissue samples....

Phytophthora obscura sp nov., a new species of the novel Phytophthora subclade 8d

Creator:: Gruenwald, N. J., Werres, S., Goss, E. M., Taylor, C. R., and Fieland, V. J.
Abstract:: A new Phytophthora species was detected (i) in the USA, infecting foliage of Kalmia latifolia, (ii) in substrate underneath Pieris, and (iii) in Germany in soil samples underneath Aesculus hippocastanum showing disease symptoms. The new species Phytophthora obscura sp. nov. is formally named based on phylogenetic analysis, host range, Kochs...

Distribution and Population Dynamics of Plant-Parasitic Nematodes in Oregon Vineyards, and Their Effects on Vine Growth [1994-1995]

Creator:: Ingham, Russell E., Forge, Thomas, Strik, Bernadine C., and Pinkerton, J. N.
Abstract:: Objectives 1. Survey Oregon vineyards for the presence, identity and abundance of plant-parasitic nematodes. 2. Relate the distribution and abundance of potentially pathogenic species to viticultural practices and site characteristics. 3. Evaluate the efficacy of Nemacur for reducing populations of plant-parasitic nematodes. 4. Document seasonal changes in the abundance of...

Genome sequences of Phytophthora enable translational plant disease management and accelerate research

Creator:: Grünwald, Niklaus J.
Abstract:: Des séquences entières ou partielles de génomes deviennent de plus en plus accessibles. En ce qui concerne plusieurs systèmes plante-agent pathogène, nous abordons l’ère du recéquençage du génome. Les premiers génomes de Phytophthora, P. ramorum et P. sojae, ont été disponibles à partir de 2004, suivis de près par celui...

Abandoning Sverdrup’s critical depth hypothesis on phytoplankton blooms

Creator:: Behrenfeld, Michael J.
Abstract:: The Critical Depth Hypothesis formalized by Sverdrup in 1953 posits that vernal phytoplankton blooms occur when surface mixing shoals to a depth shallower than a critical depth horizon defining the point where phytoplankton growth exceeds losses. This hypothesis has since served as a cornerstone in plankton ecology and reﬂects the...

Kinetic and Spectroscopic Analysis of the Inactivating Effects of Nitric Oxide on the Individual Components of Azotobacter vinelandii Nitrogenase

Creator:: Hyman, Michael R., Seefeldt, Lance C., Morgan, Vance, Arp, Daniel J., and Mortenson, Leonard E.
Abstract:: The effects of nitric oxide (NO) on the individual components of Azotobacter vinelandii nitrogenase have been examined by kinetic and spectroscopic methods. Incubation of the Fe protein (Av2) for 1 h with stoichiometries of 4- and 8-fold molar excesses of NO to Av2 dimer resulted in a complete loss of...

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,...

Developing Models for the Forage Ratios of Culiseta melanura and Culex erraticus using Species Characteristics for Avian Hosts

Creator:: Estep, Laura K., McClure, Christopher J. W., Burkett-Cadena, Nathan D., Hassan, Hassan K., Unnasch, Thomas R., and Hill, Geoffrey E.
Abstract:: Studies of mosquito preferences for avian hosts have found that some bird species are at greater risk than others of being fed upon by mosquitoes. The ecological factors that determine this interspecific variation in avian host use by mosquitoes have been little studied, despite the possibility that such variation may...
