Stability of reporter gene expression and RNAi in transgenic poplars over multiple years in the field under vegetative propagation

Creator:

Li, Jingyi

Abstract:

Stable expression of transgenes is required for commercial uses of genetically engineered trees. To better understand the stability of transgene expression under field conditions, we studied transgene expression and RNA interference (RNAi)-induced transgene suppression in 2,480 transgenic poplars (460 transgene insertion events) over three years. Stability of expression was assessed...

Exploration of the feasibility of developing a winter hardy 'Marion' blackberry through genetic engineering

Creator:

Meng, Rengong

Abstract:

Experiments focusing on plant growth regulators’ concentrations and combination, mineral salt formulations and TDZ pretreatment formations were conducted to optimize in vitro shoot regeneration from leaf and petiole explants of 'Marion' blackberry. Optimum shoot formation was obtained when stock plants were incubated in TDZ pretreatment medium for three weeks before...

How do engineering students develop and reason with concepts of electricity within a project-based course?

Creator:

Bledsoe, Karen E.

Abstract:

Reform in science education has often emphasized task-based learning as an instructional method to improve student understanding and retention of concepts, and to promote the development of reasoning and problem-solving. Yet studies assessing student knowledge at the beginning and end of a task-based class show mixed results. Students in task-based...

Generative evaluation of instruction in an Honors College, using small group instructional diagnosis : more than dots on a page

Creator:

Ringle, Judith Ann

Abstract:

Instruction in a University Honors College was evaluated using Small Group Instructional Diagnosis (SGID), a qualitative evaluation process. Fifty-one class sections were evaluated over a three-year period to determine what worked to help students learn, what did not work, and suggestions for improvement. Seven instructors used both SGID and an...

Dissecting mechanics of chromosome segregation and cleavage furrow induction

Creator:

Chen, Wei

Abstract:

Accurate chromosome segregation and cell cleavage are critical to maintaining genomic integrity. Both events involve the spindle apparatus, but the exact mechanics is as puzzling as the contradicting models proposed in the last two centuries. In this dissertation, current prevailing models of chromosome segregation and cell cleavage are tested using...

The relationships between fluctuations in oceanographic conditions, forage fishes, predatory fishes, predator food habits, and juvenile salmonid marine survival off the Columbia River

Creator:

Emmett, Robert L.

Abstract:

Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...

Public investment policy and industry incentives in life science research

Creator:

Wang, Chenggang

Abstract:

The biorevolution in the 1970’s greatly stimulated investment in life-science research. The present dissertation is aimed at evaluating the impact of US public investment on industrial investment in life-science research. The focus is on three major life-science fields: biology, medicine, and agriculture. A dynamic model of industrial R&D investment is...

Oregon’s secondary agricultural education teachers’ level of computer-based technology integration, perceptions of barriers to computer-based technology integration, and the relationship to learning styles

Creator:

Gardner, Reynold D.

Abstract:

The focus of this research was to examine the relationship between the Oregon secondary agricultural education teachers’ level of computer-based technology integration, perceptions of barriers to computer-based technology integration, and learning style preferences. Additionally the correlational analysis of the level of computer-based technology integration and the following demographic variables was...

The economics of carbon sequestration in western Oregon forests

Creator:

Im, Eun Ho

Abstract:

This study considered regional forest policies for sequestering carbon in existing forests in western Oregon. A model of log markets in western Oregon was employed to examine the impacts of forest policy changes on future carbon stock, harvests, and management activities. A carbon tax program, as a mitigation option for...

Traditional ecological knowledge to develop and maintain fire regimes in northwestern California, Klamath-Siskiyou bioregion : management and restoration of culturally significant habitats

Creator:

Lake, Frank K.

Abstract:

The use of Native American fire regimes evolved in the Klamath-Siskiyou bioregion over millennia. A mixture of Native American and Euro-American socio-cultural management has developed from adaptations to climate, topography, ecological processes, and land use practices. This research incorporates Traditional Ecological Knowledge (TEK) to partially examine the role of tribal...
