A Panel of Histone H3 Mutations to Investigate Centromere Maintenance and Gene Silencing

Creator:: Esposito, Madison L.
Abstract:: Modifications of histone tail amino acid residues are necessary for many reactions involving chromatin. These processes can produce transcriptionally active, euchromatic, or inactive, heterochromatic, segments of DNA. The formation and maintenance of facultative heterochromatin is critical for the proper growth and development of many eukaryotes. Euchromatin can be changed into...

A phenological examination of terrestrial invertebrate abundance at H. J. Andrews Experimental Forest, Oregon

Creator:: Mackereth, Kailan F.
Abstract:: Abstract Understanding the effects of climate change on forest ecosystems requires exploration of the relationships of different components of the system, such as the response of biota to local hydrology, temperature, precipitation, and elevation. The Long-term Ecological Research Program at the H. J. Andrews Experimental Forest, located in the Western...

Analysis of threats to Galápagos Marine Iguanas (Amblyrhynchus cristatus)

Creator:: Spangler, Sarah Elizabeth
Abstract:: Galápagos marine iguana population sizes have been declining since first contact with humans.This decline has historically been attributed mainly to predation by invasive species, but additional human-caused threats exist today. My thesis conducts an analysis of the present threats to the species and determines which are the most severe.Modern threats...

Biosorption Studies of Acid Green 3 Dye

Creator:: Torres, Martine I.
Abstract:: Abstract Current methods employed in the textile industry are unsustainable because they use an abundance of water in the dying process, and discharge the waste into the environment, causing adverse health effect on aquatic life and local communities. The technology that is in place to remove dye from textile effluents...

Creating Isogenic Cell Cultures for Functional Studies of DNA Mismatch-Repair

Creator:: Sarver, Kimberly
Abstract:: Colorectal cancer (CRC), the third leading cause of cancer death in the USA, depends on early detection for patient survival. Early detection is improved with the identification of high risk individuals. Risk of CRC development is a complex interaction between an individual’s genetics and environmental exposures. Polycyclic Aromatic Hydrocarbons (PAHs)...

Cyclic electron flow : Powering unique motility and alternative nitrogen uptake in Synechococcus WH8102 during nitrogen limited growth

Creator:: Dittrich, Jake E.
Abstract:: Global atmospheric carbon levels are continuing to rise from pre-industrial revolution levels. One of the main regulators of global atmospheric carbon levels, and thus climate, is the world's oceans. Unicellular marine cyanobacteria account for a large percent of total marine carbon fixation. We measured chlorophyll-specific ¹⁴C uptake rates (P[superscript b])...

Developing Trap and Kill Technologies to Improve Management of the Western Spotted Cucumber Beetle (Diabrotica undecimpunctata undecimpunctata) and the Western Striped Cucumber Beetle (Acalymma trivittatum)

Creator:: Alderman, Katie
Abstract:: The western spotted cucumber beetle (Diabrotica undecimpunctata undecimpunctata) and the western striped cucumber beetle (Acalymma trivittatum) are pests of many crops, including vegetable, fruit, and nursery crops. Pesticides are commonly used to control this pest. Trap and kill technologies are under development as use in an alternative control for cucumber...

Development, adaptation and testing of remote, non-powered sampling systems fortemporal characterization of hydraulically fractured shale systems

Creator:: Neumann, Kyle
Abstract:: Extraction of natural gas from shale formations using the process of hydraulic fracturing (fracking) requires the use of thousands of cubic meters of fluid. Hydraulic fracturing fluids are pumped under pressure into shale formations, fracturing the shale and releasing pockets of trapped gases. When the pressure in a natural gas...

DNA Mismatch Repair-Dependent Suppression of Genotoxicity of Benzo[a]pyrene Diol Epoxide

Creator:: Kernan, Casey P.
Abstract:: DNA mismatch repair (MMR) plays an important role in preserving genomic stability and reducing cancer risk. Environmental exposures to polycyclic aromatic hydrocarbons (PAHs) are believed to contribute significantly to carcinogenesis. PAHs are found in food, air, water and soil and upon bioactivation can form diol epoxides which are electrophilic in...

EBB1, an AP2/ERF Transcription Factor, Promotes Transgenic Shoot Development in Populus

Creator:: Ree, Joseph
Abstract:: Recalcitrance to transformation makes genetic engineering of many valuable plants infeasible for practical use. Transitory host modification during transformation using transgenes offers a possible means of overcoming this obstacle. In prior work in our laboratory, the genes GA20ox7 and EBB1 were found to increase regeneration in vitro. In this project,...
