Hundreds Of Scn-Resistant Soybean Varieties Available For 2014, Gregory L. Tylka 2014 Iowa State University

Hundreds Of Scn-Resistant Soybean Varieties Available For 2014, Gregory L. Tylka

Integrated Crop Management News

The soybean cyst nematode (SCN) is a serious yield-reducing pathogen of soybeans. It is present in many fields throughout the Midwest, wherever soybeans are grown.

To produce profitable soybean yields in fields infested with SCN, farmers should grow SCN-resistant soybean varieties. SCN-resistant soybeans can produce high yields while keeping SCN population densities from increasing.


Dahp Oxime: A Transition State Mimic Inhibitor Of Dahp Synthase, Naresh Balachandran 2014 McMaster University

Dahp Oxime: A Transition State Mimic Inhibitor Of Dahp Synthase, Naresh Balachandran

Open Access Dissertations and Theses

The rise of bacterial infections and increase of antibiotic resistant bacteria has become a major problem in the treatment of bacterial infections. The use and overuse of antibiotics, and the inherent ability of bacteria to adapt to their environment, have lead to the emergence of strains that are resistant to all antibiotics. Ideally, new targets for antibacterial drug therapy would be essential to the virulence of most or all bacteria. That is, antibiotics exploiting these targets would have broad spectrum activity. 3-Deoxy-D-arabinoheptulosonate-7- phosphate (DAHP) synthase could be such a target. This enzyme catalyzes the condensation of erythrose 4-phosphate (E4P) and ...


A Characterization Of The Dynamic Interaction Between The Pro-Apoptotic Protein Bid And The Mitochondrial Outer Membrane, Aisha Shamas-Din Ms. 2014 McMaster University

A Characterization Of The Dynamic Interaction Between The Pro-Apoptotic Protein Bid And The Mitochondrial Outer Membrane, Aisha Shamas-Din Ms.

Open Access Dissertations and Theses

Bcl-2 family of proteins regulate apoptosis at the level of the mitochondrial outer membrane (MOM) through both protein-protein and protein-membrane interactions. While the role of the membrane as the “locus of action” has been recognized, the detailed molecular mechanisms and the consequences of the interactions of Bcl-2 family members with the membrane are yet to be fully understood. The findings presented here focus on the dynamic interactions of Bcl-2 proteins, most notably tBid with the MOM, and their functional significance on mitochondrial outer membrane permeabilization. We show that the activation of tBid is a multi-step process that is regulated by ...


Investigation Of Competence Heterogeneity In Streptococcus Milleri Group Clinical Isolates, Anne-Marie G. Lacroix 2014 McMaster University

Investigation Of Competence Heterogeneity In Streptococcus Milleri Group Clinical Isolates, Anne-Marie G. Lacroix

Open Access Dissertations and Theses

The Streptococcus Milleri/Anginosus group (SMG) includes Streptococcus anginosus, Streptococcus constellatus and Streptococcus intermedius. The SMG is found in healthy individuals but these bacteria are most known clinically for being associated with invasive disease and more recently, airway infections including cystic fibrosis (CF). The SMG like many other streptococci are naturally competent, being able to actively bind, uptake and integrate extracellular DNA. Competence regulation involves a competence-stimulating peptide (CSP) derived from the ComC precursor and a two- component signaling system (a histidine kinase ComD and its response regulator ComE). In this study, I examined the distribution of CSP/ComD sequences ...


Diatom Flora In Subterranean Ecosystems: A Review, Elisa Falasco, Luc Ector, Marco Isaia, Carlos E. Wetzel, Lucien Hoffmann, Francesca Bona 2014 University of South Florida

Diatom Flora In Subterranean Ecosystems: A Review, Elisa Falasco, Luc Ector, Marco Isaia, Carlos E. Wetzel, Lucien Hoffmann, Francesca Bona

International Journal of Speleology

In scarcity of light and primary producers, subterranean ecosystems are generally extremely oligotrophic habitats, receiving poor supplies of degradable organic matter from the surface. Human direct impacts on cave ecosystems mainly derive from intensive tourism and recreational caving, causing important alterations to the whole subterranean environment. In particular, artificial lighting systems in show caves support the growth of autotrophic organisms (the so-called lampenflora), mainly composed of cyanobacteria, diatoms, chlorophytes, mosses and ferns producing exocellular polymeric substances (EPSs) made of polysaccharides, proteins, lipids and nucleic acids. This anionic EPSs matrix mediates to the intercellular communications and participates to the chemical exchanges ...

Panicum Mosaic Virus Complex And Biofuels Switchgrass, Catherine Louise Stewart 2014 University of Nebraska - Lincoln

Panicum Mosaic Virus Complex And Biofuels Switchgrass, Catherine Louise Stewart

Biological Systems Engineering--Dissertations, Theses, and Student Research

New switchgrass (Panicum virgatum L.) cultivars are being developed for use as a biofuel pyrolysis feedstock. Viral pathogens have been reported in switchgrass, but their importance in biofuel cultivars is not well known. In 2012 surveys of five switchgrass breeding nurseries in Nebraska, plants with mottling and stunting— symptoms associated with virus infection—had an incidence of symptomatic plants within fields as high as 59%. Leaves from 120 symptomatic plants were analyzed by ELISA for Panicum mosaic virus (PMV) and four other viruses known to infect switchgrass. Most samples (87%) were positive for PMV, and fewer than 8% for the ...


Rna Interference As A Tool For The Functional Analysis Of Genes In The Colorado Potato Beetle, Leptinotarsa Decemlineata (Say), Ashley Danielle Yates 2014 University of Nebraska - Lincoln

Rna Interference As A Tool For The Functional Analysis Of Genes In The Colorado Potato Beetle, Leptinotarsa Decemlineata (Say), Ashley Danielle Yates

Dissertations and Student Research in Entomology

RNA interference (RNAi) is a naturally occurring phenomenon in eukaryotes in which a double-stranded RNA (dsRNA) suppresses the expression of a target gene. RNAi has markedly changed the way in which functional genetics studies are performed, especially in non-model organisms. In insects, the efficacy of RNAi is influenced by several factors, including the species and the methods of dsRNAs delivery.

The Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), is a pest of the plant family Solanaceae. RNAi in the CPB is of interest for potential use in insect management and as a tool to study the interaction with host plants ...

Effects Of Sorting Prior To Feeding Zilpaterol Hydrochloride And Effects Of Different Implant Strategies On Feedlot Performance And Carcass Characteristics Of Steers And Heifers, Fred H. Hilscher Jr

Theses and Dissertations in Animal Science

Two experiments evaluated the effects of sorting and feeding Zilpaterol hydrochloride (ZH) to steers on feedlot performance and carcass characteristics. In Exp. 1, treatments compared unsorted cattle either fed ZH or not, and three treatments utilizing 1 sort at the beginning, middle or end of the finishing period. In Exp. 2, treatments compared unsorted cattle fed ZH, and two treatments that utilized 1 sort based on initial BW or 4 sorts at the end of the finishing period. Feeding ZH increased BW, HCW and percentage of overweight carcasses; however, sorting decreased carcass weight standard deviations, and percent overweight carcasses. Feeding ...


The Evolution Of Genomic Imprinting: Theories, Predictions And Empirical Tests, M M. Patten, L Ross, J P. Curley, David C. Queller, R Bonduriansky, J B. Wolf 2014 Washington University in St. Louis

The Evolution Of Genomic Imprinting: Theories, Predictions And Empirical Tests, M M. Patten, L Ross, J P. Curley, David C. Queller, R Bonduriansky, J B. Wolf

Biology Faculty Publications

The epigenetic phenomenon of genomic imprinting has motivated the development of numerous theories for its evolutionary origins and genomic distribution. In this review, we examine the three theories that have best withstood theoretical and empirical scrutiny. These are: Haig and colleagues’ kinship theory; Day and Bonduriansky’s sexual antagonism theory; and Wolf and Hager’s maternal–offspring coadaptation theory. These theories have fundamentally different perspectives on the adaptive significance of imprinting. The kinship theory views imprinting as a mechanism to change gene dosage, with imprinting evolving because of the differential effect that gene dosage has on the fitness of matrilineal ...

Feeding Condensed Distillers Solubles To Feedlot Finishing Steers And The Effects Of Feed Additives In Adaptation Diets, Marie E. Harris

Theses and Dissertations in Animal Science

By-products from the dry-milling ethanol process can be used in cattle diets to replace corn. There is a significant interaction between corn processing methods as CCDS concentration increases in the diet. Improvements are observed for SFC in final BW, ADG, and G:F over DRC. An experiment was conducted to determine if greater concentrations of CCDS could be fed in SFC based diets and maintain or improve performance. Performance and carcass characteristics were evaluated with increasing concentrations of CCDS at 0, 9, 18, 27, or 36% in place of SFC in feedlot finishing diets. As CCDS concentration increased, DMI decreased ...


Single Tube, Multiple Enzyme Reaction For Detection Of Uv And Oxidative Damage In Forensic Physiological Stains, Nicholas J. Eurek 2014 University of Nebraska - Lincoln

Single Tube, Multiple Enzyme Reaction For Detection Of Uv And Oxidative Damage In Forensic Physiological Stains, Nicholas J. Eurek

Theses and Dissertations in Biochemistry

For decades, the use of DNA as a biological tool has revolutionized forensic investigations. The primary use of this genetic evidence is for identification of a victim or suspect through short tandem repeat (STR) profiling. However, the usefulness of this evidence can be compromised through inhibition of PCR, damage to the DNA, or low copy number. Here, we investigate damage induced to DNA by environmental factors. UV light is known to damage DNA by the formation of cyclobutane pyrimidine dimers, 6-4 photoproducts, and strand breaks. These lesions can stall polymerase action or misincorporate bases during extension. Oxidative damage is also ...


Characterization Of Protein-Protein Interactions Mediated By The Second Exon Of The Varicella-Zoster Virus Orf45/42 Terminase Subunit, Elizabeth A. Syster-Clevenger 2014 Indiana University – Purdue University Fort Wayne

Characterization Of Protein-Protein Interactions Mediated By The Second Exon Of The Varicella-Zoster Virus Orf45/42 Terminase Subunit, Elizabeth A. Syster-Clevenger

Master's Theses

Varicella-zoster virus (VZV), a member of the Herpesviridae, is ubiquitous human pathogen with significant morbidity and mortality in healthy and immunocompromised individuals. Primary infection causes a systemic viremia and skin rash known as varicella, and more commonly referred to as chickenpox. Latency is established in the nervous system during primary infection and can reactivate to cause zoster, more commonly known as shingles. Current treatments for VZV infection target viral DNA replication, primarily the DNA polymerase. However, novel small molecule inhibitors that target other viral replication processes, for example viral DNA encapsidation, offer additional therapeutic options. Seven conserved open reading frames ...

The Show Cave Of Diros Vs. Wild Caves Of Peloponnese, Greece. Distribution Patterns Of Cyanobacteria, Vasiliki Lamprinou, Daniel B. Danielidis, Adriani Pantazidou, Alexandra Oikonomou, Athena Economou-Amilli

International Journal of Speleology

The karst cave ‘Vlychada’of Diros, one of the oldest show caves in Peloponnese, sustains extended phototrophic biofilms on various substrata – on rocks inside the cave including speleothems, and especially near the artificial lighting installation (‘Lampenflora’). After a survey of the main abiotic parameters (Photosynthetically Active Radiation -PAR, Temperature -T, Relative Humidity -RH, Carbon Dioxide -CO2) three clusters of sampling sites were revealed according to Principal Component Analysis (PCA): i) the water gallery section predominately influenced by CO2, ii) the dry passages influenced by RH and PAR, and iii) the area by the cave exit at the dry ...


Some Effects Of The Human Genome Project On The Erdős Collaboration Graph, Chris Fields 2014 Claremont Colleges

Some Effects Of The Human Genome Project On The Erdős Collaboration Graph, Chris Fields

Journal of Humanistic Mathematics

The Human Genome Project introduced large-scale collaborations involving dozens to hundreds of scientists into biology. It also created a pressing need to solve discrete mathematics problems involving tens of thousands of elements. In this paper, we use minimal path lengths in the Erdős Collaboration Graph between prominent individual researchers as a measure of the distance between disciplines, and we show that the Human Genome Project brought laboratory biology as a whole closer to mathematics. We also define a novel graph reduction method and a metric that emphasizes the robustness of collaborative connections between researchers; these can facilitate the analysis of ...
