Characterization Of A Novel Fungal-Specific Gene, Fug1, In Fusarium Verticillioides, John Byron Ridenour

Graduate Theses and Dissertations

Filamentous fungi are responsible for numerous plant and animal diseases. The filamentous ascomycete Fusarium verticillioides is a globally important pathogen of maize, capable of causing severe yield reductions and economic losses. Also of substantial concern is the contamination of infected kernels with fumonisins, toxic secondary metabolites linked to toxicoses in humans and livestock. The number of sequenced fungal genomes is rapidly increasing. However, functional characterization of fungal genes has not progressed at a comparable rate. In pathogenic fungi, uncharacterized genes represent a source for novel virulence factors or anti-fungal targets. Therefore, to fully understand the genetic mechanisms underlying fungal pathogenesis, …

Identification Of Root-Knot Nematodes (Meloidogyne Spp.) Of Arkansas Using Molecular Diagnostics, Churamani Khanal

Graduate Theses and Dissertations

Root-knot nematodes (Meloidogyne spp.) are highly-adaptable, obligate plant parasites distributed worldwide. In addition, root-knot nematodes are an economically important genus of plant-parasitic nematodes. Meloidogyne incognita, M. arenaria, M. javanica, M. hapla and M. graminis have been reported from Arkansas during 1964 to 1994. Previous identifications were based primarily on morphological characters and host differentials. In this study, identification using molecular diagnostics methods was performed to identify Meloidogyne species present in Arkansas. A total of 106 soil and root samples from 36 of the 75 counties were collected and processed to obtain root-knot nematodes. Polymerase chain reaction (PCR) was performed …

Dissection Of Gray Leaf Spot Of Maize Through Functional Genomics, Robert Louis Hirsch

Graduate Theses and Dissertations

Gray leaf spot, caused by Cercospora zeae-maydis, is a devastating disease of maize that reduces yields and increases management costs. C. zeae-maydis penetrates maize leaves through stomata, but the biological and molecular bases of this process are poorly understood. The goal of this research was to elucidate the biological parameters of stomatal infection in C. zeae-maydis, and to identify and characterize novel genetic pathways involved in stomatal sensing and pathogenesis. Histopathological observations of a GFP-expressing strain of C. zeae-maydis during infection of maize indicated that the fungus responded to host-derived stomatal cues during the infection process. C. zeae-maydis was observed …

Mangrove forests are national treasures of the United Arab Emirates (UAE) and other arid countries with limited forested areas. Mangroves form a crucial part of the coastal ecosystem and provide numerous benefits to society, economy, and especially the environment. Mangrove trees, specifically Avicennia marina, are studied in their native habitat in order to characterize their population structure, aboveground biomass, and soil properties. This study focused on Eastern Mangrove Lagoon National Park in Abu Dhabi, which was the first mangrove protected area to be designated in UAE. In situ measurements were collected to estimate Avicennia marina status, mortality rate (%), …

Evaluation Of Medicago Truncatula Accessions For Triterpene Saponins And Their Potential Impacts On Plant Pests, Samantha Roberson

Graduate Theses and Dissertations

Plants have developed numerous ways to protect themselves from microbes and insects, including producing secondary metabolites that negatively impact an invading pathogen or pest. Saponins are specialized metabolites found in many plant species and may play a role in protecting the plant. Though saponins are found in many plant species, triterpene saponins are found primarily in dicotyledons, including legumes. Medicago truncatula is a model system for studying legume biology and some accessions accumulate high concentrations of saponins. Accessions of M. truncatula known to have differing levels of saponins in both foliar and root tissues were tested for their suitability as …

Judge Posner, Judge Wilkinson, And Judicial Critique Of Constitutional Theory, Marc O. Degirolami, Kevin C. Walsh

Notre Dame Law Review

Judge Richard Posner’s well-known view is that constitutional theory is useless. And Judge J. Harvie Wilkinson III has lambasted constitutional theory for the way in which its “cosmic” aspirations threaten democratic self-governance. Many other judges hold similar views. And yet both Posner and Wilkinson—in the popular press, in law review articles, and in books—have advocated what appear to be their own theories of how to judge in constitutional cases. Judicial pragmatism for Posner and judicial restraint for Wilkinson seem to be substitutes for originalism, living constitutionalism, political process theory, and so on. But both Posner and Wilkinson also deny that …

Effects Of Operating Conditions On Removal Of Trace-Amount Testosterone By Nitrocellulose Filter Membrane, Ying Liang

Department of Environmental Engineering: Theses and Other Student Research

Hormone can be removed by membrane filtration via membrane interception, sorption and diffusion. However, the effects of operating conditions of membrane filtration on hormone removal have not been evaluated systematically. In this study, the removal of testosterone by nitrocellulose membranes under different operating conditions (e.g., initial testosterone concentrations, sample volumes, flow rates and membrane pore sizes) was investigated. ¹⁴C-labeled testosterone was used as a tracer to determine the removal of testosterone in the filtration process, and a hydrodynamic model was used to determine dispersion coefficient (D) associated with the operating conditions and radius of hormone molecule. Results indicate that …

A Large-Scale, Rapid Public Health Response To Rabies In An Organ Recipient And The Previously Undiagnosed Organ Donor, R. M. Wallace, Danielle Stanek, S. Griese, D. Krulak, Neil M. Vora, Virginia Kan, +14 Additional Authors

Medicine Faculty Publications

This article describes and contrasts the public health response to two human rabies cases: one organ recipient diagnosed within days of symptom onset and the transplant donor who was diagnosed 18 months post-symptom onset. In response to an organ-transplant-related rabies case diagnosed in 2013, organ donor and recipient investigations were conducted by multiple public health agencies. Persons with potential exposure to infectious patient materials were assessed for rabies virus exposure. An exposure investigation was conducted to determine the source of the organ donor's infection. Over 100 persons from more than 20 agencies spent over 2700 h conducting contact investigations in …

Granularity Helps Explain Seemingly Irrational Features Of Human Decision Making, Joe Lorkowski, Vladik Kreinovich

Departmental Technical Reports (CS)

Starting from well-known studies by Kahmenan and Tarsky, researchers have found many examples when our decision making -- and our decision making -- seem to be irrational. In this chapter, we show that this seemingly irrational decision making can be explained if we take into account that human abilities to process information are limited; as a result, instead of the exact values of different quantities, we operate with granules that contain these values. On several examples, we show that optimization under such granularity restriction indeed leads to observed human decision making. Thus, granularity helps explain seemingly irrational human decision making.

Methods: This four-phase study employed a case study design allowing for multiple means of data collection …

Recruitment Facilitation And Spatial Pattern Formation In Soft-Bottom Mussel Beds, John A. Commito, Ann E. Commito, Rutherford V. Platt, Benjamin M. Grupe, Wendy Dow Piniak, Natasha J. Gownaris, Kyle A. Reeves, Allison M. Vissichelli

Environmental Studies Faculty Publications

Mussels (Mytilus edulis) build massive, spatially complex, biogenic structures that alter the biotic and abiotic environment and provide a variety of ecosystem services. Unlike rocky shores, where mussels can attach to the primary substrate, soft sediments are unsuitable for mussel attachment. We used a simple lattice model, field sampling, and field and laboratory experiments to examine facilitation of recruitment (i.e., preferential larval, juvenile, and adult attachment to mussel biogenic structure) and its role in the development of power-law spatial patterns observed in Maine, USA, soft-bottom mussel beds. The model demonstrated that recruitment facilitation produces power-law spatial structure similar …

Voys Lessons: Whirling Words In Chaucer’S “House Of Rumour", Nicola Blake

Publications and Research

“Voys Lessons: Whirling Words in Chaucer’s ‘House of Rumour’” examines the lability of sound and its use in the dissemination, transposition, and authorship of stories within The House of Fame, a text exemplifying the mobility and flexibility of misused or unhinged words, as expressed through sound as opposed to text. By engaging the use and interpretation of sound in contrast to words, this new reading concentrates on the idea of narrative as material artifact with limited stasis. Geffrey’s pseudo-authorship, through his voyeuristic stance, engages the textuality of sounds and shows the related subtlety, elasticity, and democratic sociohistorical aspect of …

Transformative Skin: The Ongoing Legacy Of Inuit And Yupik Women's Tattoos, Mariah Carrillo

Art & Art History ETDs

Feminine indigenous tattoo traditions of the American Arctic have often been overlooked in scholarly literature due to colonial pre-conceptions regarding native gender roles and the nature of adornment. Modern Euro-American conceptions of skin and self often rely on rigid, essentialized categories, such as race and gender, to mark identity onto the individual body. However, the Inuit and Yupik peoples of Alaska and Canada regarded personal essence as fluid and transformative, a belief made visible in the networks of sewn lines that declared a womans status and agency. This text examines both written ethnological records and a diverse range of material …

Listening To Silence: A Rhetorical Examination Of Silence In The Tale Type The Maiden Who Seeks Her Brothers, Crystal Stephens

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Fairy tales are an integral part of our culture and have been for hundreds of years. Most of us grew up hearing certain stories, reading the Grimm brothers, watching Disney adaptations of classic tales, and passing these things on to the next generation. But even though we sometimes dismiss fairy tales as we get older as “stories for children,” that does not mean that fairy tales do not play an important role in our lives and cultures. Studying and understanding fairy tales can provide insight into our history, our cultures, and ourselves. As stated by Dan Ben-Amos, “The folktale has …
