Arabidopsis Shoot Gravitropism Requires The Mediator Coactivator Complex, Gabriella Newton

Honors Theses

Gravitropism is a plant response to gravity in directing the growth of its organs, such as the root and the stem. Gravity is sensed by statocytes, unique cells that contain starch-filled amyloplasts, which trigger gravitropic growth response by modulating the distribution of growth hormone auxin in the elongation zone of the stem and root. Despite the fact that multiple factors have been identified as key regulators of shoot negative gravitropism, how these factors are regulated at the transcriptional level is largely unknown. In this study, we explore the role of transcriptional machinery in regulating shoot gravity sensing and responses by …

The Transcriptional Regulator Ctra Controls Gene Expression In Alphaproteobacteria Phages: Evidence For A Lytic Deferment Pathway, Elia Mascolo, Satish Adhikari, Steven M. Caruso, Tagide Decarvalho, Anna Folch Salvador, Joan Serra-Sagristà, Ry Young, Ivan Erill, Patrick D. Curtis

Faculty and Student Publications

Pilitropic and flagellotropic phages adsorb to bacterial pili and flagella. These phages have long been used to investigate multiple aspects of bacterial physiology, such as the cell cycle control in the Caulobacterales. Targeting cellular appendages for adsorption effectively constrains the population of infectable hosts, suggesting that phages may have developed strategies to maximize their infective yield. Brevundimonas phage vB_BsubS-Delta is a recently characterized pilitropic phage infecting the Alphaproteobacterium Brevundimonas subvibrioides. Like other Caulobacterales, B. subvibrioides divides asymmetrically and its cell cycle is governed by multiple transcriptional regulators, including the master regulator CtrA. Genomic characterization of phage vB_BsubS-Delta identified the presence …

Computational Tools To Expedite The Identification Of Potential Pxr Modulators In Complex Natural Product Mixtures: A Case Study With Five Closely Related Licorice Species, Manal Alhusban, Pankaj Pandey, Jongmin Ahn, Bharathi Avula

Faculty and Student Publications

The genus Glycyrrhiza, comprising approximately 36 spp., possesses complex structural diversity and is documented to possess a wide spectrum of biological activities. Understanding and finding the mechanisms of efficacy or safety for a plant-based therapy is very challenging, yet it is crucial and necessary to understand the polypharmacology of traditional medicines. Licorice extract was shown to modulate the xenobiotic receptors, which might manifest as a potential route for natural product-induced drug interactions. However, different mechanisms could be involved in this phenomenon. Since the induced herb-drug interaction of licorice supplements via Pregnane X receptor (PXR) is understudied, we ventured out to …

Indoloquinoline-Mediated Targeted Downregulation Of Kras Through Selective Stabilization Of The Mid-Promoter G-Quadruplex Structure, Alexandra Maria Psaras, Rhianna K. Carty, Jared T. Miller, L. Nathan Tumey

Faculty and Student Publications

KRAS is a well-validated anti-cancer therapeutic target, whose transcriptional downregulation has been demonstrated to be lethal to tumor cells with aberrant KRAS signaling. G-quadruplexes (G4s) are non-canonical nucleic acid structures that mediate central dogmatic events, such as DNA repair, telomere elongation, transcription and splicing events. G4s are attractive drug targets, as they are more globular than B-DNA, enabling more selective gene interactions. Moreover, their genomic prevalence is increased in oncogenic promoters, their formation is increased in human cancers, and they can be modulated with small molecules or targeted nucleic acids. The putative formation of multiple G4s has been described in …

Mercury Methylation Potentials In Sediments Of An Ancient Cypress Wetland Using Species-Specific Isotope Dilution Gc-Icp-Ms, Derek D. Bussan, Chris Douvris, James V. Cizdziel

Faculty and Student Publications

Wetlands are of a considerable environmental value as they provide food and habitat for plants and animals. Several important chemical transformations take place in wetland media, including the conversion of inorganic mercury (Hg) to monomethylmercury (MeHg), a toxic compound with a strong tendency for bioconcentration. Considering the fact that wetlands are hotspots for Hg methylation, we investigated, for the first time, Hg methylation and demethylation rates in an old growth cypress wetland at Sky Lake in the Mississippi Delta. The Sky Lake ecosystem undergoes large-scale water level fluctuations causing alternating periods of oxic and anoxic conditions in the sediment. These …

The Ties That Bind: Creole Networks And Reform In New Granada During The Age Of Revolution, 1780-1811, Philip John Baltuskonis

Electronic Theses and Dissertations

At the beginning of the nineteenth century, Spanish Americans were immersed in a practical Enlightenment that aimed to improve society during the Age of Revolution (1780-1850). In the city of Santafé de Bogotá, elites comprised of Spaniards and creoles (Spaniards born in the Americas) joined in scientific expeditions, higher education, creating newspapers, and proposing economic and educational reforms that all promised to bring prosperity to the Viceroyalty of New Granada (present-day Colombia, Venezuela, Ecuador, and Panama). Rather than a source of major confrontation, elites’ activities aligned with the Spanish Crown’s interest in turning its American kingdoms into centers of wealth. …

Seeing Queer Joy In Mississippi: Pride Parades In Tupelo, Starkville, And Oxford, Ellie Campbell

Electronic Theses and Dissertations

In May of 2016, Oxford, Mississippi, held its first LGBTQ+ Pride parade in recent memory. That first Oxford Pride was part of a wave of LGBTQ+ celebrations that began in the state in 2015 and 2016 and continue to the present day. Though the pandemic forced many to cancel or go online, communities across Mississippi have continued to organize Pride parades and other celebrations of LGBTQ+ identities since 2015, a marked contrast from earlier periods. In a state often depicted as actively hostile to queer people, these Pride events make queer southern communities visible in new ways, while also revealing …

Social Distance, Stigma, And Help-Seeking: A Comparison Of Lay And Professional Conceptualizations Of Autism In The Southern Us, Christian Shannon Courson

Electronic Theses and Dissertations

Understanding stigma, help-seeking and barriers to treatment for persons with Autism Spectrum Disorder (ASD) is essential for informing interventions toward increased relevance and utility. An array of sociocultural and individual factors can influence lay beliefs and behavioral responses to ASD, including stigma and social distancing (i.e., preference for distance from autistic individuals). It is important to consider the Explanatory Models of ASD among helping professionals (e.g., health care, education) as they are likely touchstones along the help-seeking pathway for children with ASD. The purpose of this study was twofold: 1) to explore factors in the southern United States associated with …

Perceptions Of Sexual Refusals: Not So Black And White, Lavina Ying Ho

Electronic Theses and Dissertations

Sexual assault is an issue affecting approximately 1 in 5 women. Compared to White women, Black women report higher rates of lifetime rape, are at risk of developing physical/mental health issues post-assault (e.g., depression, posttraumatic stress disorder, and substance abuse), and are less likely to engage in help-seeking after sexual victimization. Research reveals the manner in which a woman refuses a sexual advance can influence a man’s perceptions of the genuineness of her refusal. Sexual refusals that are explicit (e.g., not wanting to have sex due to religious beliefs) are identified more quickly as violating a woman’s boundaries than sexual …

Fabrication Of Porous Extended-Release Tablets Using Dual Nozzle Fused Deposition Modeling 3d Printing Techniques, Sung-Chi Lee

Electronic Theses and Dissertations

The aim of this study was to fabricate shell-core porous tablet formulations by fused deposition modeling dual nozzle three-dimensional printing coupled with hot-melt extrusion techniques. Acetaminophen was selected as the model drug for this study owing to its pH-independent property. The 3-point bend test and the stiffness test were performed to investigate the printability of filaments. The stiffness constant, k, was calculated to represent the printability by fitting the breaking distances and stress data into Hooke’s law. The formulation 1 (F1) and formulation 2 (F2) filaments were printed successfully by demonstrating the preferred hardness with 16.74±3.55 and 14.72±2.20 respectively in …

Mississippi Modernism: The River Valley And Race In American Culture, 1892-1945, William C. Palmer

Electronic Theses and Dissertations

Mississippi Modernism looks to the Mississippi River Valley of the last decade of the nineteenth century and the first few decades of the twentieth century to analyze the ways individuals expressed and determined their experience in the changing world. By engaging with theories of modernity from Marshall Berman and the Black modernism of Houston A. Baker, Jr. this work proposes the Mississippi watershed as a region where individuals indulge in the processes of modernism remaking the environments, both urban and rural, surrounding them. By thinking about the “dry” and “wet” valleys envisioned by European settlers as Christopher Morris terms it, …

Teaching In A Remediation Nation: Exploring Journalism And Mass Communication Faculty Perceptions Of Their Professional Practice, Andrew Mark Abernathy

Electronic Theses and Dissertations

Research shows many new college students may be remedial in English language arts or mathematics (Jaggers & Bickerstaff, 2018). For faculty in journalism and mass communication (JMC) fields, teaching struggling student writers can be especially challenging as these students may not have the fundamental knowledge to build applied writing skills upon. Thus, this lack of readiness for collegiate writing poses challenges to not only these students’ academic success, but also their transition into media professions. Embedded remediation—an alternative to traditional, prerequisite remediation—is one strategy that JMC faculty can use to support struggling student writers. This dissertation explores how JMC faculty …

Genomic Analysis And Metabolic Potential Of Myxobacteria, Hanan Albataineh

Electronic Theses and Dissertations

Myxobacteria are known for their large genomes that bestow them with a distinct lifestyle that is characterized by fruiting body formation, gliding motility, social interactions, predation, and secondary metabolite production. The powerful combination of whole-genome sequencing and bioinformatics-driven analysis of sequence data has delivered unexpected insights into myxobacterial microbial communities. We applied these two approaches to investigate the chemical space and biosynthetic potential of myxobacteria. Mining different myxobacterial genomes for biosynthetic gene clusters led us to the discovery of a cryptic acyl-homoserine lactone (AHL) synthase encoded in the genome of the myxobacterium Archangium gephyra. Bioinformatic analysis of this AHL synthase …
