Cellular events conditioned by the Np gene of Pisum sativum L. in response to reduced UV light, weevil oviposition, and bruchins

Creator:: Ketter, Ann P.
Abstract:: In Pisum, the Np gene conditions two mitotic responses - to bruchid weevil oviposition on the pod and to reduced UV light. Oviposition by the weevil results in tumorous or neoplastic growth under the egg. Biochemically active compounds, called bruchins, were isolated from two bruchid insects (Doss et al, 2000)....

Identification of an aerotaxis transducer in Vibrio cholerae

Creator:: Boin, Markus A.
Abstract:: The ability to move towards favorable environmental conditions, called chemotaxis, is common among motile bacteria. In particular aerotaxis has been extensively studied in Escherichia coli. Three putative aer gene homologs were identified in the V. cholerae genome designated VCAer-1 (VC0512) VCAer-2 (VCA0658), and VCAer-3 (VCA0988). Deletion analyses indicated that only...

Initiation of coral/algal symbioses : the role of cell surface lectin/glycan interactions in recognition and specificity

Creator:: Wood-Charlson, Elisha M.
Abstract:: Mutualistic associations between cnidarians, such as corals, and photosynthetic dinoflagellate algae provide the trophic and structural foundation of coral reef ecosystems. In many cases, this intracellular mutualism is highly specific and must be established anew for each generation of host corals. The ability to maintain partner specificity across generations implies...

Decision support systems for forest biodiversity management : a review of tools and an analytical-deliberative framework for understanding their successful application

Creator:: Gordon, Sean N.
Abstract:: The complexity of forest management has increased with the scope of resources of concern and the level of scrutiny from stakeholders. The design and use of specialized computer software, often referred to as “decision support systems” (DSS), is one method for helping managers deal with this complexity. DSS have proven...

Glyphosate-resistance in Italian ryegrass (Lolium multiflorum): evaluation and investigation of the mechanisms of resistance

Creator:: Perez-Jones, Alejandro
Abstract:: A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....

Quantitative resistance to Puccinia striiformis f. sp. hordei in barley near-isogenic (BISON) lines

Creator:: Richardson, Kelley L.
Abstract:: Quantitative resistance (QR) to disease is usually more durable than qualitative resistance, but its genetic basis is not well understood. We used the barley/barley stripe rust pathosystem as a model for the characterization of the QR phenotype and associated genomic regions. As an intermediate step in the preparation of near-isogenic...

Inner-shelf circulation off the central Oregon Coast

Creator:: Kirincich, Anthony R.
Abstract:: Inner-shelf circulation and mechanisms of across-shelf transport of water masses were examined using seven years of observations collected by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) program, a long-term monitoring effort along the central Oregon coast. Since 1998, moored velocity and hydrographic measurements have been obtained during the...

Plasma enhanced growth of carbon nanotubes

Creator:: Ford, Neil I.
Abstract:: Carbon nanotubes (CNTs) are grown using plasma enhanced chemical vapor deposition (PECVD). A modified radio frequency (RF) parallel-plate plasma etching system serves as the growth reactor. The effects of process parameters, including temperature, pressure, and C2H2:NH3 ratio, are studied. CNTs are grown on glass substrates with Al underlayers and Ni...

Do settling mussels (Mytilus spp.) prefer macroalgae over artificial substrates? : a test of collector preference along the Oregon Coast

Creator:: Howieson, John
Abstract:: This study investigated whether a device commonly used to measure settlement of mussel larvae for ecological studies, the Tuffy™, functions uniformly whether placed in a bed of filamentous algae or on bare rock. During the summers of 2004 and 2005, the number of mussel larvae settling on Tuffys in patches...
