Characterization Of Five Brevibacillus Bacteriophages And Their Genomes, Michael Allen Sheflo Jun 2016

Characterization Of Five Brevibacillus Bacteriophages And Their Genomes, Michael Allen Sheflo

Theses and Dissertations

Brevibacillus laterosporus (B. laterosporus) is a pathogen difficult to distinguish from Paenibacillus larvae (P. larvae), and contributes to Colony Collapse Disorder (CCD) of honeybees. To develop a biocontrol agent to limit its presence, bacteriophages were isolated from Utah County soil samples and used to infect B. laterosporus isolated from Utah County honey and larvae samples. Since CCD is prevalent in Utah beehives, bacteriophage that infect and lyse B. laterosporus may be isolated and characterized. Pathogens were isolated from soil samples, and 16S rRNA gene tests initially identified the strains as P. larvae. Bacteriophages were isolated, purified, and amplified sufficiently to …

Glutamate And Gaba Receptor-Mediated Plasticity In The Mesolimbic Dopamine System By Alcohol, Ashley Cerise Nelson Jun 2016

Glutamate And Gaba Receptor-Mediated Plasticity In The Mesolimbic Dopamine System By Alcohol, Ashley Cerise Nelson

Theses and Dissertations

Alcoholism is a devastating chronic relapsing disorder with significant costs to individuals and society. The mesolimbic dopamine (DA) system plays an important role in regulating reward and addiction. GABA neurons located in the ventral tegmental area (VTA) regulate VTA DA neuron activity, and are a relevant target for alcohol in the brain. VTA GABA neurons exhibit marked hyperexcitability during withdrawal from ethanol. Past research has demonstrated that the motivational effects of opiates cause a change in VTA GABA(A) receptors in opiate-dependent animals, which switch from a GABA-induced hyperpolarization of GABA neurons to a GABA-induced depolarization. The focus of this study …

High-resolution genetic and physical maps are invaluable tools for building accurate genome assemblies, and interpreting results of genome-wide association studies (GWAS). Previous genetic and physical maps anchored good quality draft assemblies of the domestic cat genome, enabling the discovery of numerous genes underlying hereditary disease and phenotypes of interest to the biomedical science and breeding communities. However, these maps lacked sufficient marker density to order thousands of shorter scaffolds in earlier assemblies, which instead relied heavily on comparative mapping with related species. A high-resolution map would aid in validating and ordering chromosome scaffolds from existing and new genome assemblies. Here, …

Competition Dynamics Within Communities Of Desert Wildlife At Water Sources, Lucas Keith Hall Jun 2016

Competition Dynamics Within Communities Of Desert Wildlife At Water Sources, Lucas Keith Hall

Theses and Dissertations

Water is a vital resource for species inhabiting arid and semi-arid regions and can shape the biotic communities that we observe. Because water is considered a limiting resource for many species in desert environments, there is the potential for competitive interactions between species to occur at or around water sources. For this dissertation I tested hypotheses related to resource competition among different species of wildlife in the Great Basin and Mojave Deserts of western Utah. Chapter one evaluated the influence of feral horses (Equus caballus) on patterns of water use by communities of native birds and mammals. Chapter …

Effectiveness Of The Toxicant Drc-1339 In Reducing Populations Of Common Ravens In Wyoming, Luke W. Peebles, Michael R. Conover Jun 2016

Effectiveness Of The Toxicant Drc-1339 In Reducing Populations Of Common Ravens In Wyoming, Luke W. Peebles, Michael R. Conover

Wildland Resources Faculty Publications

Common raven (Corvus corax) populations have increased several-fold in the western United States during the past century; these birds cause problems when they kill new-borne lambs and calves and depredate nests of greater sage-grouse (Centrocercus urophasianus). The toxicant DRC-1339 is used by U.S. Department of Agriculture/Animal and Plant Health Inspection Service Wildlife Services to manage common raven populations and reduce the severity of these problems, but it is difficult to determine how many ravens are killed by an application because carcasses are rarely found. We examined the effectiveness of DRC-1339 applications for preventative control of ravens at 3 landfills and …

Evaluation Of The Estrogenic And Osmoregulatory Impacts Of Exposure To 4-Nonylphenol Pollution In The Estuarine Arrow Goby, Clevelandia Ios, Kaitlin Marie Johnson Jun 2016

Evaluation Of The Estrogenic And Osmoregulatory Impacts Of Exposure To 4-Nonylphenol Pollution In The Estuarine Arrow Goby, Clevelandia Ios, Kaitlin Marie Johnson

Master's Theses

Recent evidence indicates that some of California’s coastal estuaries are contaminated with the chemical 4-nonylphenol (4-NP). Tissue burdens of 4-NP detected in the intertidal arrow goby (Clevelandia ios) in California are among the highest recorded worldwide, however, it remains unknown whether these fish are impacted by this 4-NP contamination. 4-NP is an established endocrine disrupting compound with estrogenic properties that can alter reproductive function. Furthermore, evidence that estrogens can modulate iono- and osmo-regulatory function in fishes implies that estuarine fishes exposed to 4-NP may also experience an impaired ability to maintain hydromineral balance. In Chapter 1 of this …

Orrm6 Is A Novel Organellar Rna Recognition Protein Involved In Plastid Rna Editing In Arabidopsis Thaliana, Justin B. Hackett Jun 2016

Orrm6 Is A Novel Organellar Rna Recognition Protein Involved In Plastid Rna Editing In Arabidopsis Thaliana, Justin B. Hackett

Masters Theses

RNA editing is a conserved mechanism of post-transcriptional modification in eukaryotes that changes specific nucleotides in RNA transcripts. In flowering plants, this is limited to cytidine to uridine deaminations. Plastid RNA editing events are critical for plastid development and the loss of editing can result in untranslated or non-functional proteins. There have been 40 RNA editing events discovered in the Arabidopsis thaliana plastid. Recently organellar RNA recognition motif (ORRM) proteins have been shown to broadly affect plastid RNA editing and interact with sequence specific trans-factor pentatricopeptide repeat proteins (PPR). ORRM proteins contain a canonical RNA recognition motif that has been …

Influence Of Release Timing On Survival And Movements Of Translocated Mule Deer (Odocoileus Hemionus) In Utah, David C. Smedley Jun 2016

Influence Of Release Timing On Survival And Movements Of Translocated Mule Deer (Odocoileus Hemionus) In Utah, David C. Smedley

Theses and Dissertations

Translocation of wildlife has become common practice for wildlife managers charged with management of animals on increasingly modified landscapes. Translocation can be used to reduce population density in the source area, supplement existing populations, reestablish extirpated populations, and establish new populations. Mule deer (Odocoileus hemionus) are a species of great interest to the public in western North America. Although translocations have been used to manage mule deer, very little has been done to document the outcomes of this management practice. The purpose of this research was to evaluate movement, site fidelity, space use, and survival of translocated mule …

Narva, Blair D. Siegfried

Department of Entomology: Faculty Publications

The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, is an important maize pest throughout most of the U.S. Corn Belt. Bacillus thuringiensis (Bt) insecticidal proteins including modified Cry3Aa and Cry34/35Ab1 have been expressed in transgenic maize to protect against WCR feeding damage. To date, there is limited information regarding the WCR midgut target sites for these proteins. In this study, we examined whether a cadherin-like gene from Diabrotica virgifera virgifera (DvvCad; Gen-Bank accession # EF531715) associated with WCR larval midgut tissue is necessary for Cry3Aa or Cry34/ 35Ab1 toxicity. Experiments were designed to examine the sensitivity of WCR to …

Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay Jun 2016

Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay

Loma Linda University Electronic Theses, Dissertations & Projects

Touted among the major achievements in the diagnosis and management of Prostate cancer (PCa) in the past few decades has been, the dramatic decline of men with advanced/metastatic PCa at diagnosis coupled with a significant improvement ( >90%) in the five and ten year survival rates of the disease. Non-palpable PCa (potentially clinically treatable disease) now accounts for 70-80% of all newly diagnosed cases of PCa. Preceding these changes by about a decade was the introduction of Prostatic Specific Antigen (PSA) into clinical practice; first as biomarker for monitoring response to therapy and subsequently as a complementary screening tool. It …

Genes Encoding Flower- And Root-Specific Functions Are More Resistant To Fractionation Than Globally Expressed Genes In Brassica Rapa, Naiyerah F. Kolkailah Jun 2016

Genes Encoding Flower- And Root-Specific Functions Are More Resistant To Fractionation Than Globally Expressed Genes In Brassica Rapa, Naiyerah F. Kolkailah

Master's Theses

Like many angiosperms, Brassica rapa underwent several rounds of whole genome duplication during its evolutionary history. Brassica rapa is particularly valuable for studying genome evolution because it also experienced whole genome triplication shortly after it diverged from the common ancestor it shares with Arabidopsis thaliana about 17-20 million years ago. While many B. rapa genes appear resistant to paralog retention, close to 50% of B. rapa genes have retained multiple, paralogous loci for millions of years and appear to be multi-copy tolerant. Based on previous studies, gene function may contribute to the selective pressure driving certain genes back to singleton …

The Effects Of Quorum Sensing And Temperature On The Soluble Proteome Of Vibrio Salmonicida, Christopher L. Massey Jun 2016

The Effects Of Quorum Sensing And Temperature On The Soluble Proteome Of Vibrio Salmonicida, Christopher L. Massey

Master's Theses

Vibrio salmonicida causes cold-water vibriosis in salmon populations around the world and causes financial damage to fisheries designed to farm these salmon. Very little is known about the physiology of how V. salmonicida causes disease and measures to contain vibriosis are restricted to either vaccinating individual fish against disease or administering antibiotics when an outbreak is detected. These procedures are costly and increase the risk for selection of antibiotic-resistant V. salmonicida strains. A recent reoccurrence of outbreaks in Norwegian fisheries provided incentive to better understand the virulence mechanisms of V. salmonicida. In this thesis, a proteomic approach was used to …

Rearing Temperature Affects The Expression Of Proteins In The Adhesive Of The Striped Acorn Barnacle, Balanus Amphitrite, Melissa J. Daugherty Jun 2016

Rearing Temperature Affects The Expression Of Proteins In The Adhesive Of The Striped Acorn Barnacle, Balanus Amphitrite, Melissa J. Daugherty

Master's Theses

Barnacles are dominant hard–fouling organisms in marine waters. They attach to substrates by secreting a complex proteinaceous adhesive. Understanding the chemical composition of this multi–protein underwater adhesive and how it is affected by environmental variables, such as oceanic temperatures, is critical for developing nontoxic solutions to control biofouling. Previous experiments in our lab revealed an inverse relationship between critical removal stress (CRS) and temperatures at which barnacles were reared. Further investigations showed that this correlation is not attributed to differences in physical properties such as barnacle size or short–term changes in the viscosity of adhesive. Therefore, the observed effects may …

The Role Of The Transcriptional Antiterminator Rfah In Lipopolysaccharide Synthesis, Resistance To Antimicrobial Peptides, And Virulence Of Yersinia Pseudotuberculosis And Yersinia Pestis, Jared Michael Hoffman Jun 2016

The Role Of The Transcriptional Antiterminator Rfah In Lipopolysaccharide Synthesis, Resistance To Antimicrobial Peptides, And Virulence Of Yersinia Pseudotuberculosis And Yersinia Pestis, Jared Michael Hoffman

Theses and Dissertations

RfaH is a unique bacterial protein that enhances transcription of a select group of long operons in many Gram-negative bacteria. Operons regulated by RfaH possess an upstream operon polarity suppressor sequence, which recruits the RfaH protein to the RNA polymerase during transcription of genes, most of which are involved in the synthesis of cell-surface features. These include synthesis of the lipopolysaccharide (LPS) core and O-antigen in Salmonella and Escherichia coli, as well as F-plasmid conjugation pilus and capsule in E. coli. LPS is an important virulence factor in many Gram-negative bacteria, and protects Y. pseudotuberculosis against host antimicrobial …
