Responses Of Predatory Myxobacteria To Prey Signaling Molecules & Features Of A Pseudomonas Prey Avoiding Predation, Shukria Akbar
Electronic Theses and Dissertations
Gram-negative unicellular myxobacteria, along with their multicellular lifestyle andbiologically active specialized metabolites, are known for the predatory interactions with Gram-negative/ Gram-positive bacteria and fungi. Although myxobacterial predation range have been exploited extensively, little is known about the prey associated molecules contributing to myxobacterial predator-prey dynamics. By employing transcriptomics and untargeted metabolomics approaches, we demonstrate two structurally distinct classes of signaling molecules from Gram-negative bacterial prey elicit significant omics responses from myxobacteria, Myxococcus xanthus and Cystobacter ferrugineus. An overlapping and general response to acylhomoserine lactones, whereas a distinctive response to a quinolone signaling molecule is observed from both myxobacteria. Similarly, by …
Quantifying Microbial Resistance To Nematode Predation, Tyler Bacon
Quantifying Microbial Resistance To Nematode Predation, Tyler Bacon
Electronic Theses and Dissertations
The selection pressure of predation has encouraged the development of defense traits that can make an individual species more environmentally stable. In addition to biotic pressures, abiotic factors could lead to disruption of predator-prey balance within ecosystems. Consequently, it is significant to better understand how environmental factors can influence predator-prey interactions and how responses may, in turn, affect communities. A current challenge within microbial communities is to understand which intraspecific traits associated with such defense strategies are important for microbial-prey responses to predation, and how the responses vary across environments revealing GxE interactions. In this study, I examined microbial-predator prey …

Responses Of Myxobacteria To Plant-Related Chemosignals Suggests Their Roles In The Rhizobiome, Barbara Iyare Adaikpoh
Electronic Theses and Dissertations
In the rhizosphere, plants curate and maintain distinct rhizobiome, some of which serve as secondary defense mechanisms against pathogenic microorganisms. Additionally, in response to biotic stress, plants generate phytohormones which regulate signaling pathways to activate systemic resistance. These phytohormones contribute to the chemical space within the rhizosphere in addition to other low-molecular-weight metabolites used for cell-to-cell communication within species and across kingdoms. However, little is known about the influences of stress-related phytohormones on beneficial bacteria even though biocontrol strategies abundantly explore plant-beneficial microorganisms to manage pathogens in agricultural systems. Myxobacteria are competent predators of plant pathogens and have demonstrated responses …

Comparative Study Of Agrogeophysical Methods For Identifying Soil Pipes, Md Abdus Abdus Samad
Electronic Theses and Dissertations
Soil erosion is considered the greatest challenge for soil management and agri-food production threatening human habitat and livelihood. Although soil erosion due to surficial processes has been well studied, the role of the subsurface process such as internal soil pipes has often been overlooked. Internal soil pipes directly contribute to total soil loss in agricultural fields that severely threaten agricultural sustainability. Locating, measuring, and mapping internal soil pipes and their networks are vital to assess the total soil loss in agricultural fields. Internal soil pipes are not commonly visible at the surface, and their subsurface networks rarely follow the surface …

Roll Down Like Water: Photography, Social Movements, And Surveillance In Memphis, Tenneessee, Andrea Morales
Electronic Theses and Dissertations
“There’s really no such thing as the ‘voiceless,’” Arundhati Roy said during a speech after earning her 2004 Sydney Peace Prize for literature. “There are only the deliberately silenced, or the preferably unheard.” These words help illuminate the tensions between dominant narrative and power, as well as photography’s role arbitrating both. This paper will explore those relationships and their impacts through existing documentary and sociological studies, but more pointedly will use the experience of making a body of work about social movements in Memphis, Tennessee. Over the last seven years, I’ve used critical race theory framework to make photographs rooting …

The Aesthetics Of Repair: The Way Of Zen And Appreciation, Tyler Ellis Dobbs
Electronic Theses and Dissertations
The nature objects and how beings interact with them has long been a debate in the philosophic tradition. One aspect of this I have taken a look at is the aesthetic qualities entailed in this with particular attention paid to repair. In particular I explore the blurring of the subject-object distinction and the role of narrative in human engagement. I based my research and arguments primarily from Buddhist and Japanese Zen theories and ideas. Special attention was paid to the philosopher Kitaro Nishida and the Kyoto School philosophy tradition and ideas from Mahayana Buddhism.

Components Of War: How Combat Shapes Political Behavior, Travis W. Endicott
Electronic Theses and Dissertations
After military service is over, veterans are left to try to acclimate to their new lives. They take the lessons learned through their military career and they apply it to their daily life. One area of veteran life that remains understudied is the way that military service, combat experience specifically, alters political attitudes and behavior. The main focus of this dissertation is to understand the way that military combat alters political attitudes among military veterans. Instead of analyzing military veterans as one homogenous group, I separate veterans by combat experience. Building from the military psychology literature on combat trauma, I …
Influence Of Rage Signaling On Cellular Communication In Diabetes-Mediated Vascular Calcification, Amber Michelle Kennon
Influence Of Rage Signaling On Cellular Communication In Diabetes-Mediated Vascular Calcification, Amber Michelle Kennon
Electronic Theses and Dissertations
Chronic hyperglycemia is one of the main characteristics of type 2 diabetes mellitus (T2DM). With the increased prevalence of T2DM, the risk of cardiovascular complications, including heart attack or stroke, is increased. Complications linked to the vasculature are increased vascular calcification (VC) or mineral deposition within the medial layer of conducting arteries. Under calcification conditions, vascular smooth muscle cells (VSMCs) undergo an osteogenic switch to an osteoblast-like cell and begin producing bone proteins. Chronic hyperglycemia can also result in increased extracellular matrix (ECM) synthesis, accumulation, and crosslinking. One of the cell types responsible for increased ECM synthesis are ‘activated’ fibroblasts …

The community engagement field has grappled with critical questions around its failure to effectuate institutional change that will permit colleges and universities to create a more just society. At the same time, the University of Mississippi has struggled to reconcile its own institutional legacy of forced integration alongside an ambitious public mission in a state recognized for persistent poverty and inequality.
Enzyme-Initiated Admicellar Polymerization, Elaheh Shakeri
Enzyme-Initiated Admicellar Polymerization, Elaheh Shakeri
Electronic Theses and Dissertations
Admicellar polymerization was developed in the 1980s as an economical method for modifying various surfaces. In admicellar polymerization, a low monomer to initiator (M/I) ratio was traditionally required to overcome this limitation and achieve high polymer conversion when oxygen was present in the headspace and dissolved in the reaction medium. To develop an environmentally friendly, cost-efficient, and feasible deoxygenation and initiation technique, we studied the use of glucose oxidase (GOx) in admicellar polymerization. In this method, GOx acts as the catalyst in the oxidation of ?-D-glucose, while consuming oxygen and generating hydrogen peroxide and D-glucono-?-lactone. There are many advantages of …
