Mutagenic mechanisms associated with perturbations of DNA precursor biosynthesis in phage T4

Creator:: Ji, Jiuping
Abstract:: A crucial factor in determining the accuracy of DNA replication is maintenance of a balanced supply of deoxyribonucleoside triphosphates (dNTPs) at replication forks. Perturbation of dNTP biosynthesis can induce dNTP pool imbalance with deleterious genetic consequences, including increased mutagenesis, recombination, chromosomal abnormalities and cell death. Using the T4 bacteriophage system,...

Identification of candidate genes for survival and their use in predicting field performance of Pacific oyster Crassostrea gigas families in coastal waters

Creator:: Lang, Robert Paul
Abstract:: Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for...

Community organization and succession in rocky intertidal surfgrass beds

Creator:: Turner, Teresa
Abstract:: Succession and organization of rocky intertidal zone surfgrass beds (Phyllospadix scouleri Hook) were examined experimentally at two sites on the Oregon coast. The interaction of three attributes of the plant -- high persistence, high preemption, and slow recovery -- strongly influences the organization of surfgrass beds. Permanent plots indicate that...

The Miridae (Hemiptera : Heteroptera) associated with noble fir, Abies procera Rehd

Creator:: Cooper, G. M.
Abstract:: The Miridae, or plant bugs, associated with noble fir, Abies procera Rehd., are discussed. Thirty six species of the Miridae were collected from noble fir. Twenty five of these species are considered only "visitors" to noble fir. The study does not deal with these species. Noble fir is a host...

Sulfide metabolism in Lucina floridana, a sulfur symbiont-containing marine clam

Creator:: Larabee, Jeannine Kay
Abstract:: Lucina floridana is an intertidal clam that contains intracellular, sulfur-oxidizing symbiotic bacteria in its gills. These bacteria are chemolithoautotrophic, using the energy from the oxidation of reduced sulfur compounds to power carbon fixation. Although sulfide is an energy-rich compound, it is also toxic to aerobic metabolism and autooxidizes in the...

Gene expression in the liver of rainbow trout, Oncorhynchus mykiss, during the stress response

Creator:: Momoda, Tracey S.
Abstract:: The extent to which responses to stress are maladaptive or adaptive to the long-term survival of fish remains to be better understood. The aim of this study was to identify differentially expressed genes in the livers of rainbow trout, Oncorhynchus mykiss, responding to an experimental stressor. Gene expression responses were...

The detection of superoxide and implications for amyotrophic lateral sclerosis

Creator:: Robinson, Kristine M.
Abstract:: Mutations to superoxide dismutase were the first proven cause of Lou Gehrig’s disease (amyotrophic lateral sclerosis; ALS) implicating superoxide in the selective death of motor neurons that characterizes ALS. Nitric oxide competes effectively with superoxide dismutase for superoxide to form the powerful oxidant peroxynitrite. Endogenous formation of peroxynitrite can kill...

Novel icosanoids from the red marine alga Farlowia mollis

Creator:: Solem, Michele Lee
Abstract:: Farlowia mollis is a marine red alga that grows in the intertidal region along the coast of Oregon. We began studying the chemistry of this alga after a survey of Oregon seaweeds revealed possibly interesting chemistry and antimicrobial activity in its crude organic extract. Over the past three years the...

Isolation and characterization of a larval crustacean salt gland from the brine shrimp Artemia salina

Creator:: Lowy, Robert Joel
Abstract:: A method for isolating the salt gland (SG) from the larval brine shrimp has been developed. This extra-renal organ is removed from 5-10% of Stage Inauplii by vortexing after incubating the animals at 37°C for 8 hours in a saline solution buffered with 100 mM sodium phosphate at pH 7.6....

Characteristics of NADPH-cytochrome P-450 reductase in the house fly (Musca domestica, L.) and the blow fly (Phormia regina, Meigen)

Creator:: Vincent, Daniel R.
Abstract:: NADPH-cytochrome P-450 reductase, an important enzyme in the cytochrome P-450-dependent microsomal monooxygenase system, was purified from insecticide-resistant (R) and -susceptible (S) house flies (Musca domestica, L.) and from the black blow fly (Phormia regina, Weigen). Proteolytic degradation to a P-450 - inactive form of the reductase was reduced during the...
