Response Of Sorghum Stalk Pathogens To Brown Midrib Plants And Soluble Phenolic Extracts From Near Isogenic Lines, Deanna L. Funnell-Harris, Patrick M. O'Neill, Scott E. Sattler, Tammy Gries, Mark A. Berhow, Jeffrey F. Pedersen

Department of Plant Pathology: Faculty Publications

Sorghum [Sorghum bicolor (L.) Moench] has drawn attention as potential feedstock for lignocellulosic biofuels production, and reducing lignin is one way to increase conversion efficiency. Little research has been previously conducted to assess the response of reduced lignin sorghum lines to the Fusarium stalk rot pathogens Fusarium verticillioides and Fusarium proliferatum and the charcoal rot pathogen, Macrophomina phaseolina. Loss of function mutations in either the Brown midrib (Bmr) 6 or 12 gene that both encode a monolignol biosynthetic enzyme in the pathway that produces subunits of the lignin polymer, results in reduced lignin content. Near-isogenic bmr6, …

Best Practices For Population Genetic Analyses, Niklaus J. Grünwald, Sydney E. Everhart, B. J. Knaus, Z. N. Kamvar

Department of Plant Pathology: Faculty Publications

Population genetic analysis is a powerful tool to understand how pathogens emerge and adapt. However, determining the genetic structure of populations requires complex knowledge on a range of subtle skills that are often not explicitly stated in book chapters or review articles on population genetics. What is a good sampling strategy? How many isolates should I sample? How do I include positive and negative controls in my molecular assays? What marker system should I use? This review will attempt to address many of these practical questions that are often not readily answered from reading books or reviews on the topic, …

The Assembly Factor Pet117 Couples Heme A Synthase Activity To Cytochrome Oxidase Assembly, Nicholas G. Taylor, Samantha Swenson, Nicholas J. Harris, Edward M. Germany, Jennifer L. Fox, Oleh Khalimonchuk

Department of Biochemistry: Faculty Publications

Heme a is an essential metalloporphyrin cofactor of the mitochondrial respiratory enzyme cytochrome c oxidase (CcO). Its synthesis from heme b requires several enzymes, including the evolutionarily conserved heme a synthase (Cox15). Oligomerization of Cox15 appears to be important for the process of heme a biosynthesis and transfer to maturing CcO. However, the details of this process remain elusive, and the roles of any additional CcO assembly factors that may be involved remain unclear. Here we report the systematic analysis of one such uncharacterized assembly factor, Pet117, and demonstrate in Saccharomyces cerevisiae that this evolutionarily conserved protein is necessary for …

Apocalypse Then, Apocalypse Now: Rethinking Joan Of Arc In The Twenty-First Century, Timothy M. Thibodeau

Quidditas

Joan of Arc has stood alone among legendary figures of the Middle Ages in her capacity to be appropriated and employed for a host of modern noble causes. However, a fresh examination of Joan’s words and deeds reveals that her aims and objectives were not the universal “greater goods” of modern activists who have used her story to craft their own narratives. I propose that Joan’s continued attractiveness as a cultural icon now faces two major obstacles. First, in the wake of the rapid secularization of modern western society and the evolution of social mores related to gender identity and …

Phenotypic And Genotypic Characterization Of Relevant Sclerotinia Sclerotiorum Isolates, Thomas J. Justo Miorini, Anthony G. Pannullo, T. Hornby, Robert Higgins, Sydney E. Everhart, James R. Steadman

Department of Plant Pathology: Faculty Publications

Knowledge of pathogen population structure is useful to identify isolates for screening cultivars and lines for resistance. For S. sclerotiorum, causal agent of white mold in more than 400 plant species, including common bean and soybean, breeding for resistance is particularly challenging. The objective of this study was to characterize phenotypic and genotypic variation of S. sclerotiorum isolates from soybean production areas of the U.S.A. (15), Brazil (75), and Argentina (5) to compare them with 366 isolates from dry bean characterized previously (Everhart et al., 2016).

Control Of White Mold Of Dry Bean And Residual Activity Of Fungicides Applied By Chemigation, Thomas J.J. Miorini, Carlos G. Raetano, Sydney E. Everhart

Department of Plant Pathology: Faculty Publications

Sclerotinia sclerotiorum is a necrotrophic fungal pathogen that causes white mold of dry bean (Phaseolus vulgaris L.). Chemigation with fungicides is used for disease control, but effectiveness of this application method and impact of irrigation level on residual fungicide activity in the plant over time under field conditions has not been well characterized. To assess the best method of application and fungicide for disease control, we conducted field studies in three field sites in São Paulo State in Brazil. Contact fungicide, fluazinam, was applied via center pivot at three irrigation levels (2.5, 5.1, 10.1 mm) at the Itaí field …

Structure Of The N-Glycans From The Chlorovirus Ne-Jv-1, Immacolata Speciale, Irina Agarkova, Garry Duncan, James L. Van Etten, Cristina De Castro

James Van Etten Publications

Results from recent studies are breaking the paradigm that all viruses depend on their host machinery to glycosylate their proteins. Chloroviruses encode several genes involved in glycan biosynthesis and some of their capsid proteins are decorated with N-linked oligosaccharides with unique features. Here we describe the elucidation of the N-glycan structure of an unusual chlorovirus, NE-JV-1, that belongs to the Pbi group. The host for NE-JV-1 is the zoochlorella Micractinium conductrix. Spectroscopic analyses established that this N-glycan consists of a core region that is conserved in all of the chloroviruses. The one difference is that the residue 3OMe-l-rhamnose is …

Glucose-Abl1-Tor Signaling Modulates Cell Cycle Tuning To Control Terminal Appressorial Cell Differentiation, Margarita Marroquin-Guzman, Guangchao Sun, Richard Wilson

Department of Plant Pathology: Faculty Publications

The conserved target of rapamycin (TOR) pathway integrates growth and development with available nutrients, but how cellular glucose controls TOR function and signaling is poorly understood. Here, we provide functional evidence from the devastating rice blast fungus Magnaporthe oryzae that glucose can mediate TOR activity via the product of a novel carbon- responsive gene, ABL1, in order to tune cell cycle progression during infection-related development. Under nutrient-free conditions, wild type (WT) M. oryzae strains form terminal plant-infecting cells (appressoria) at the tips of germ tubes emerging from three-celled spores (conidia). WT appressorial development is accompanied by one round …

The Environmental Impacts Of Alternative Food Waste Treatment Technologies In The U.S., Krista L. Thyberg, David J. Tonjes

Technology & Society Faculty Publications

A Life Cycle Assessment (LCA) was conducted to determine the environmental impacts of several waste treatment scenarios for a suburban New York (U.S.) municipality. The study goal was to determine if separate food waste recovery and management was environmentally sounder than waste-to-energy incineration (the baseline case). Three alternatives, enclosed tunnel composting, enclosed windrow composting, and anaerobic digestion with subsequent enclosed windrow composting of residuals, were examined considering the entire residual waste stream (not just separated food wastes). Impact categories assessed were climate change, environmental eutrophication and acidification, resource depletion, and stratospheric ozone depletion. A normalized, aggregated impact assessment was created …

Urban Elementary Science Teacher Leaders: Responsibilities, Supports, And Needs, Julianne A. Wenner

Curriculum, Instruction, and Foundational Studies Faculty Publications and Presentations

The challenge of science achievement gaps is one that scholars have struggled to solve. Teacher leadership holds great promise in closing those gaps. Therefore, the purpose of the research reported here was to explore the responsibilities and supports of formally designated science teacher leaders (STLs) in urban elementary schools that have been successful in closing science achievement gaps. Using York-Barr and Duke’s (2004) review on teacher leadership as a framework, findings from this study indicate that urban elementary STLs emphasize certain dimensions of practice (e.g., building partnerships) while deemphasizing or even omitting others (e.g., working with preservice teachers). Findings also …

Chemistry Faculty Publications

The impact of substituting Hg(II) for Zn(II) in a thiolate-bridged trinuclear cluster with parallels to a metallothionein metal cluster was investigated. A new solvomorph of [Zn(ZnL)₂](ClO₄)₂ (1) (L = N-(2-pyridylmethyl)-N-(2-(ethylthiolato)-amine) and five solvomorphs of a new compound [Hg(Zn_L)2](ClO₄)₂ (2) were characterized by single-crystal X-ray crystallography. The interplay of hydrogen bonding and aromatic-packing interactions in producing lamellar, 2D lamellar, and columnar arrangements of complex cations in the crystalline state is discussed. Both variable temperature proton nuclear magnetic resonance and electrospray ion-mass spectrometry (ESI-MS) suggest that the complex ions …

Background: The aims of this study were to determine whether a modified Qigong breathing exercise can reduce the sense of hunger and identify possible mechanisms.

Methods: The results from the test group, which performed the exercise, are compared with the control group, which performed deep breathing. Intestinal pressure measurements, stomach pH monitoring, and participant surveys were used for assessment.

Results: Stomach pH was increased by 3 (0.2) and intestinal pressure was reduced by 12 (0.5) mm Hg in the experimental group and did not change significantly in the control group. The study provides strong evidence that the exercise can significantly …

Is High Folic Acid Intake A Risk Factor For Autism?—A Review, Darrell Wiens, M. Catherine Desoto

Faculty Work

Folate is required for metabolic processes and neural development. Insuring its adequate levels for pregnant women through supplementation of grain-based foods with synthetic folic acid (FA) in order to prevent neural tube defects has been an ongoing public health initiative. However, because women are advised to take multivitamins containing FA before and throughout pregnancy, the supplementation together with natural dietary folates has led to a demographic with high and rising serum levels of unmetabolized FA. This raises concerns about the detrimental effects of high serum synthetic FA, including a rise in risk for autism spectrum disorder (ASD). Some recent studies …

Diet Induced Obesity Alters Muscle Spindle Afferent Function In Adult Mice, Lubayna Elahi

Master's Theses

Individuals with obesity are more likely to fall and exhibit balance instability. The reason for this is likely multifactorial, but there is some evidence that sensory function is impaired during obesity. We tested the hypothesis that muscle proprioceptor function is compromised in a mouse model of diet induced obesity. We used an in vitro muscle-nerve preparation to record muscle spindle afferent responses to physiological stretch and sinusoidal vibration. We compared the responses of mice on a control diet (10% kcal fat) with those eating a high fat diet (60% kcal fat) alone or in combination with either aspirin (120mg/kg/day in …

Pfizer, Jeffrey S. Harrison, Ryan Mcgowan, Kevin O'Neill, Lauren Shotwell, Joshua Torres

Robins Case Network

Pfizer was established in 1849 in Brooklyn, New York by cousins Charles Pfizer and Charles Erhart with a loan of $2,500 from Pfizer’s father.² Today, 167 years later, Pfizer Inc. has international revenues of $49 billion, which makes it the second-largest pharmaceutical manufacturer in the world.³ Despite Pfizer’s success, the company has faced many challenges over the last few decades. The pharmaceutical industry is heavily influenced by legal, political, and technological forces, and all indications are that the industry will continue to experience dramatic changes.

The Morality Of Corporate Persons, Ladelle Mcwhorter

Women, Gender and Sexuality Studies Faculty Publications

This essay provides a genealogy of corporate personhood as it exists currently in US law and places moral personhood in a similar genealogical context. This treatment demonstrates that the two are inextricably intertwined in both conception and institutionalized practices. We would do well to dismantle both; meanwhile, however, corporate personhood's implicit illiberal notion of collective mentality and responsibility may suggest possibilities for establishing collective counterforces to oppose activities of transnational for-profit corporations and mitigate their devastating political, economic, and environmental effects upon actual people and the ecosystems upon which we depend.

Integrating Lecture And Laboratory In Health Sciences Courses Improves Student Satisfaction And Performance, Kevin E. Finn, Kathleen Fitzpatrick, Zi Yan

Health Sciences Faculty Publications

Students often struggle in introductory health sciences courses; some students have difficulty in upper level classes. To address this, we converted three lecture/lab courses, traditional firstyear Anatomy and Physiology (A&P I), upper level Biomechanics, and upper level Microbiology to an integrated studio model. We used the Student Assessment of Learning Gains perceptual survey to assess student and instructor reactions to the change and analyzed rates of unsatisfactory grades and quiz performance. Reaction (220 students, 15 instructors) to the new model was highly positive, and performance improvement was seen. Student perceptions were consistent across courses and agreed closely with instructor perceptions. …
