Structural Evidence For Innervation Of A Single Epitheliomuscular Cell By Multiple Sensory Neurons In The Sea Anemone Nematostella Vectensis, Aparajita Das
Graduate Theses and Dissertations
Abstract Here, I report new ultrastructural evidence for multineuronal innervation (many-one) of a single epithelia-muscular cell in sea-anemone cnidarian Nematostella vectensis. Using Serial Block-Face Scanning Electron Microscopy (SBF-SEM) and ImageJ, I found that EMCs are located at the base of ectoderm, with an elongated cell body that includes basal processes, a bilobed nucleus, and myofibrils aligned parallel to the basal surface along with their structural quantification. Notably, I found multiple mechanosensory neurons form synapses with a single EMC. These findings enhance our understanding of cnidarian neuromuscular organization and reveal that coordination between sensory and contractile systems in N. vectensis is …

Graduate Theses and Dissertations
Freshwater ecosystems are one of the most imperiled habitats across the world with biodiversity declining rapidly. There are many stressors contributing to freshwater species declines including habitat loss and degradation, land-use changes, anthropogenic water demands, changes in precipitation and weather extremes, and pollution. Current environmental projections predict that these stressors will continue to impact freshwater ecosystems to greater extents moving forward. Stream drying from drought conditions increasing in intensity and frequency is especially concerning in northern Arkansas where seasonal drought is typical in the summer and fall months. With increased drying conditions, the elimination of shallow-water riffle habitats in streams …
Mechanisms Of Bacterial Glucokinase Inactivation Through Site-Specific Lysine Modification And Chemical Inhibition, Joseph Robert Will Andrews
Mechanisms Of Bacterial Glucokinase Inactivation Through Site-Specific Lysine Modification And Chemical Inhibition, Joseph Robert Will Andrews
Graduate Theses and Dissertations
Glycolysis and related metabolic pathways are controlled by various post-translational modifications (PTMs) that affect enzyme activity and metabolic flow. In E. coli, glucokinase (GLK) sits at the crossroads of glycolysis and the pentose phosphate pathway and carries out the first committed step of glycolysis: ATP-dependent phosphorylation of glucose. While it's known that glucose binding causes GLK to close its domains, how phosphate binding, lysine modification, and small-molecule inhibitors regulate GLK's shape and function is still not fully understood. Here, I combine structural biochemistry and enzymology to figure out how phosphate binding, specific mutations, and chemical inhibitors affect E. coli GLK. …

Characterization Of Snrk1 Signaling In Rice Growth, Reproduction, And Stress Responses Using Phenotypic And Omics Analysis, Maria Clara Faria-Bates
Graduate Theses and Dissertations
SnRK1 is an evolutionarily conserved protein kinase belonging to the SNF1/AMPK family that is composed of a catalytic subunit (α) and two regulatory subunits (β and βγ), and it has a major role in adjusting growth in response to the energy status. SnRK1 phosphorylates and alters the activities of enzymes involved in metabolism and regulates gene expression by altering the activity of chromatin-remodeling enzymes or transcription factors. Rice contains three functional paralogs of SnRK1α: OsSnRK1αA (Os05g0530500), OsSnRK1αB (Os8g0484600), and OsSnRK1αC (Os03g0289100). Although SnRK1 is known to play a central role in plant growth and stress responses, the functional specialization of …
Bats And Bacteria: Infection Dynamics At The Human-Wildlife Interface, Isabella Katherine Deanglis
Bats And Bacteria: Infection Dynamics At The Human-Wildlife Interface, Isabella Katherine Deanglis
Graduate Theses and Dissertations
As the second most diverse mammalian order, bats host an array of pathogens, some of which are known to infect humans. Synanthropic bats share spaces with humans, resulting in bat-borne pathogen exposure. While most bat-borne disease research has focused on viral pathogens, bats host numerous bacterial pathogens with zoonotic potential. By integrating a global meta-analysis with field studies in Sub-Saharan Africa, I characterize the structural attributes that facilitate shared interfaces, the bacterial pathogens present in synanthropic bats of rural Kenya, and the physiological and environmental dynamics influencing odds of infection in these synanthropic bats. Finally, I evaluate the clinical relevance …

Lumbopelvic Kinematics And Muscular Co-Contractions In Walking Prior To And Immediately Following A Bout Of Prolonged Standing., Stephanie Cotariu
Lumbopelvic Kinematics And Muscular Co-Contractions In Walking Prior To And Immediately Following A Bout Of Prolonged Standing., Stephanie Cotariu
Graduate Theses and Dissertations
Background: Prolonged standing is a common daily activity in a wide array of occupations, and approximately 44% of sample populations develop low back pain (LBP) during prolonged standing. Prolonged standing-induced LBP developers (“Pain Developers”) are three times more likely to develop clinical LBP and can therefore be considered a pre-clinical LBP population. Changes in typical gait have been observed in LBP patients, and walking has been hypothesized as being protective or preventive against LBP development. However, it is unknown whether Pain Developers exhibit similar kinematic adaptations to chronic LBP patients during common daily activities, such as walking. The exact muscular …

Dissecting The Complex Genomic Landscape Underlying Oxidative Stress Resistance Using Natural Variation In Yeast, Sonali Lakshika Anne Lenaduwe
Dissecting The Complex Genomic Landscape Underlying Oxidative Stress Resistance Using Natural Variation In Yeast, Sonali Lakshika Anne Lenaduwe
Graduate Theses and Dissertations
Stress is experienced across the tree of life. Survival in fluctuating environments depends on a robust genetic architecture. This dissertation examines the genetic and metabolic determinants underlying one such adaptive response: cross-protection. Leveraging natural variation in the stress responses of budding yeast, Saccharomyces cerevisiae, I examine the genetic variation contributing to ethanol-induced cross-protection against oxidative stress. Acquired stress resistance, in which mild pre-exposure improves survival to subsequent stresses, is prevalent across diverse organisms and can involve both same-stress and cross-protection. Using high-throughput bulk segregant analysis (BSA-seq) and advanced intercross mapping populations derived from natural yeast isolates, I identify quantitative trait …

Hormonal Control Of Seawater Acclimation In The Intestine Of The Atlantic Killifish (Fundulus Heteroclitus), Karma Je Hine
Hormonal Control Of Seawater Acclimation In The Intestine Of The Atlantic Killifish (Fundulus Heteroclitus), Karma Je Hine
Graduate Theses and Dissertations
The Atlantic killifish (Fundulus Heteroclitus) is a teleost found in brackish water estuaries, which are subject to large fluctuations in salinity, that handles osmotic stress by triggering compensatory actions across their osmoregulatory organs. As the external salinity increases, the killifish intestine exhibits a high degree of phenotypic plasticity, as the protein composition of the gut epithelium can be modified to absorb desalinated water (H2O) from ingested seawater (SW). Three osmoregulatory hormones, prolactin (P), growth hormone (GH), and cortisol (F), have been observed to be crucial for these transitions to occur in many species of teleosts, including killifish. This research sought …
Validation Of Diagnostic Markers And Linkage Mapping In Vitis × Muscadinia Hybrids, Isabella Vaughn
Validation Of Diagnostic Markers And Linkage Mapping In Vitis × Muscadinia Hybrids, Isabella Vaughn
Graduate Theses and Dissertations
The Vitis genus comprises two subgenera, Vitis (2n = 38) and Muscadinia (2n = 40), both cultivated for wine, juice, and fresh-market fruit. Vitis vinifera cultivars produce high-quality fruit but are highly susceptible to diseases endemic to the southeastern United States, while muscadines (Muscadinia rotundifolia) provide exceptional disease resistance, heat tolerance, and environmental adaptability. Hybridizing these subgenera offers a path to combine fruit quality with disease resistance; however, wide Vitis × Muscadinia (V × M) crosses remain difficult due to differences in chromosome number, genetic divergence, and reproductive barriers that reduce fertility and recombination. Recent breeding efforts have introgressed stenospermocarpic …
