Genetic And Transcriptomic Analyses Of The Rice Pathogenic Bacterium, Burkholderia Glumae, Reveal The Important Roles Of The Regulatory Gene, Tepr, For Bacterial Survival In Environmental Stresses, Jingyu Peng
LSU Master's Theses
Burkholderia glumae causes bacterial panicle blight in rice by producing the phytotoxin, toxoflavin, as a major virulence factor. Production of toxoflavin is negatively regulated by tepR, which encodes a sigma 54-dependent response regulator. In order to gain insights into the comprehensive biological functions of tepR, the genome-wide transcriptional profile dependent on tepR was analyzed through comparative transcriptome analysis between a tepR defective mutant and the wild-type strain, resulting in the identification of 238 differentially expressed genes (DEGs). Gene Ontology (GO) enrichment analysis indicated that genes involved in flagella assembly and stress response were highly enriched in tepR defective strain. Kyoto …
An Evaluation Of Close Reading For Fourth Grade Students Receiving Tier 2 Responsiveness To Intervention Services, Marcy Boudreaux-Johnson
An Evaluation Of Close Reading For Fourth Grade Students Receiving Tier 2 Responsiveness To Intervention Services, Marcy Boudreaux-Johnson
LSU Doctoral Dissertations
The primary purpose of the present study was to evaluate the effectiveness of a close reading instructional routine (also known as analytical reading decades ago) that has been described in the literature and promoted as a process to help students reading complex text independently and proficiently. A single subject alternating treatments design was implemented with six fourth grade students who had been identified as at risk for academic failure and were receiving supplemental, small-group instruction in their rural public school. The alternating treatments design allowed for a direct comparison of the close reading instructional routine and a validated reading comprehension …
Just Throw It In The Pot! The Cultural Geography Of Hidden Landscapes And Masked Performances In South Louisiana Gumbo Cooking, Corey David Hotard
Just Throw It In The Pot! The Cultural Geography Of Hidden Landscapes And Masked Performances In South Louisiana Gumbo Cooking, Corey David Hotard
LSU Doctoral Dissertations
One of Louisiana's gifts to the world is gumbo. Yet, gumbo is not just a local dish of renown. It is a metaphor which describes the people, a food that represents a region, and a symbol that stands in for the state. It is also the official dish of Louisiana. The association of gumbo with South Louisiana is recognized worldwide. The word itself evokes images of Louisiana's swampy Cajun landscapes. Yet gumbo is not indigenous to Louisiana nor is it a strictly Cajun dish. This dissertation is about the cultural and historical geography of gumbo. This study delves into the …
Pattern Mining And Events Discovery In Molecular Dynamics Simulations Data, Shobhit Sandesh Shakya
Pattern Mining And Events Discovery In Molecular Dynamics Simulations Data, Shobhit Sandesh Shakya
LSU Doctoral Dissertations
Molecular dynamics simulation method is widely used to calculate and understand a wide range of properties of materials. A lot of research efforts have been focused on simulation techniques but relatively fewer works are done on methods for analyzing the simulation results. Large-scale simulations usually generate massive amounts of data, which make manual analysis infeasible, particularly when it is necessary to look into the details of the simulation results. In this dissertation, we propose a system that uses computational method to automatically perform analysis of simulation data, which represent atomic position-time series. The system identifies, in an automated fashion, the …
Biostabilization Of Lipid Bilayers: Dealing With Water Stress In Embryos Of Artemia Franciscana, Daniel Steven Moore
Biostabilization Of Lipid Bilayers: Dealing With Water Stress In Embryos Of Artemia Franciscana, Daniel Steven Moore
LSU Doctoral Dissertations
The aim of this dissertation is to investigate stabilization of lipid bilayers during water stress by protectants found in embryos of Artemia franciscana. Two LEA proteins were used: AfrLEA2 and AfrLEA3m. AfrLEA3m was experimentally demonstrated to reside in the matrix. Two detergents were used to differentially solubilize the outer and inner membranes of mitochondria isolated from A. franciscana. Release of AfrLEA3m occurred simultaneously with the release of fumarase, a matrix-resident marker. As a second independent method to corroborate the above findings, I demonstrated that recombinant AfrLEA3m can be imported into mitochondria isolated from rat liver. Molecular modeling of AfrLEA2 and …
Gumbos As Matrices For Matrix-Assisted Laser Desorption Ionization Time Of Flight Mass Spectrometry, Hashim Abdullah Al Ghafly
Gumbos As Matrices For Matrix-Assisted Laser Desorption Ionization Time Of Flight Mass Spectrometry, Hashim Abdullah Al Ghafly
LSU Doctoral Dissertations
This work involves the investigation of a group of uniform materials based on organic salts (GUMBOS) as matrices for matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF) for analysis of hydrophobic biomolecules. GUMBOS are new class of materials that show great promise as MALDI matrices because they are able to form a thin-layer on the MS target, thereby enhancing the sample homogeneity, signal intensity, and shot-to-shot reproducibility. The detection of hydrophobic peptides using MALDI-TOF MS remains a challenge because the majority of matrices utilized are hydrophilic thereby exhibiting low affinity for hydrophobic molecules. To address this, I …
Paradoxical Agency: The Ethics Of Women's Rhetoric In Shakespeare's Rome, Catherine Riley Godbold
Paradoxical Agency: The Ethics Of Women's Rhetoric In Shakespeare's Rome, Catherine Riley Godbold
LSU Doctoral Dissertations
In this project, I address the problems of ethics and agency for women’s speech in Shakepseare’s Roman plays—Julius Caesar, Antony and Cleopatra, Titus Andronicus, and Coriolanus—and the narrative poem The Rape of Lucrece. Regardless of their rhetorical skill, virtue, or agency, it seems that the Roman women in these works are doomed to fail: either their lives become unlivable or they lose the people most important to them. This prompts the project’s initiating question: why do Shakespeare’s Roman women speak if their words have no long-term effect? For these characters, rhetorical success in Shakespeare’s Rome is dependent upon a particular …
A Peculiar Paradigm Of Perpetual Parallax, Randi Marie Willett
A Peculiar Paradigm Of Perpetual Parallax, Randi Marie Willett
LSU Master's Theses
Reality estranges as an encumbrance, a cage that traps with its clipped wings, layered veils, and stiff blankets. This hold subsists as an immovable vessel potted but never earthbound—mounted in a strained compartment, like jars with tight lids, lacking: in air, in breath, in imaginary attributes. Finally, with a last breath, an emergence blooms upon that which contextualizes momentary “reality” or rather that which defines a metaphorical escape from… actuality. My singular endeavor is to escape. My momentary escape is found in the illusory. My illusion is a perception of reality and with this perception I find my singular endeavor... …
Toll-Like Receptor 4 (Tlr4) In Acute And Chronic Renal Diseases, Anand R. Nair
Toll-Like Receptor 4 (Tlr4) In Acute And Chronic Renal Diseases, Anand R. Nair
LSU Doctoral Dissertations
Despite advances in its treatment, the incidence of renal diseases has been consistently increasing. Hence, there is a need to understand the underlying molecular mechanisms of the progression of kidney diseases. Recent research implicates inflammation as an important mediator of renal injury. We hypothesized that inhibiting Toll-like receptor 4 (TLR4), an upstream modulator of several inflammatory pathways, would prevent the progression of renal diseases. First, we determined the mechanism by which AngiotensinII (AngII)-induced inflammation is modulated by TLR4 using an in vitro model of rat tubulo-epithelial cells. We blocked TLR4 using gene silencing strategy in NRK52E cells. In TLR4-silenced cells, …

Development Of Disease Resistant Rice Using Whole Genome Sequencing And Standard Breeding Methods, Yamid Sanabria Gongora
LSU Doctoral Dissertations
Cultivated rice is the most important staple crop in the world, but diseases cause substantial losses in grain yield and quality. Sheath blight disease caused by the fungus Rhizoctonia solani is the second most important disease in rice. Most U.S varieties are tropical japonica type, but known sources of resistance in this subspecies are rare. Silva et al. (2012) identified candidate SNP associated with resistance to sheath blight by whole genome sequencing. The objectives of this study were to develop SNP-based markers from the information reported by Silva et al. (2012), to validate the markers by selective genotyping in the …

Effects Of Spinosad On Formosan Subterranean Termite, Coptotermes Formosanus Shiraki (Isoptera: Rhinotermitidae), Dependra Bhatta
LSU Master's Theses
Formosan subterranean termites, Coptotermes formosanus, are economically important structural pests of warm and humid regions. Different control measures have been developed to avoid the damage caused by them. Among the available measures, chemical treatments have predominated for the last five decades. In our study we tested the effect of spinosad, a biopesticide, on C. formosanus. Spinosad is composed of bacterial metabolites that have been widely used to control various agriculture pests. It has been tested on Kalotermitidae and Termitidae; however, not on Rhinotermitidae, the most destructive of termite families. Both no choice and choice tests were conducted using three concentrations, …

The Physical And The Divine: Images Of Inebriation In Medieval Islamic Art Of The Umayyads From The 7th To The 11th Century, Leslie Anne Schepp
The Physical And The Divine: Images Of Inebriation In Medieval Islamic Art Of The Umayyads From The 7th To The 11th Century, Leslie Anne Schepp
LSU Master's Theses
The holy text of Islam, the Qur’an, frequently refers to wine both praising and condemning the substance. Within the confines of earth, wine is prohibited because of its intoxicating nature. Believers who imbibe wine reaching an inebriated state separate themselves from God by failing to heed his law. However, for those believers righteous enough to enter the ideal, pastoral, paradisiacal afterlife, wine is not only permitted, but a great reward from Allah. In Paradise, the righteous will lounge on soft, supple couches, and will be served copious amounts of wine from goblets of silver and glass by beautiful, immortal youths. …
Identification Of Quantitative Trait Loci (Qtl) For Resistance To Stripe Rust In Wheat Variety Terral La841, Alejandro Castro Aviles
Identification Of Quantitative Trait Loci (Qtl) For Resistance To Stripe Rust In Wheat Variety Terral La841, Alejandro Castro Aviles
LSU Master's Theses
Wheat stripe rust, caused by Puccinia striiformis, is a common disease that was found primarily in the Pacific Northwest prior to 1990, with occasional minor outbreaks in the eastern wheat regions. A physiological adaptation to higher temperatures that occurred around 1990 led to stripe rust becoming a major disease problem in the Gulf Coast. Race (pathotype) changes have occurred several times since 2000, resulting in cultivars with previously effective resistance genes becoming susceptible. The cultivar LA 841, developed by the LSU AgCenter, has remained resistant to all races of stripe rust in the area for over 15 years. It contains …
This Is My Attempt To Hold On, Kimberly Reneé Jones
This Is My Attempt To Hold On, Kimberly Reneé Jones
LSU Master's Theses
I am an identical twin. The connection I share with my twin sister is intense and immediate. But now, we live over 800 miles apart. This Is My Attempt To Hold On serves as a visual metaphor for the longing for the undiluted rapport we have when we are together, and the frustrations of communicating with her through a digital device. I am constantly dissatisfied with my attempts to connect with her. I watch myself, my words, and my thoughts become diffused through the pixels. The work exists as composites of various mediums, creating a dialogue between photography, printmaking, sculpture, …
Identification Of The Causal Agent Of Leaf And Crown Rot Of Liriope In Louisiana, Carla Milena Proano
Identification Of The Causal Agent Of Leaf And Crown Rot Of Liriope In Louisiana, Carla Milena Proano
LSU Master's Theses
Leaf and crown rot of Liriope is an increasing problem affecting Liriope in the nursery and landscape for the past eight years primarily in the southeastern United States. Symptoms start with water soaking of leaves at the crown area, followed by yellowing of the entire leaf starting at the base. Affected crowns rot and leaves turn brown leading to death of the plants. Phytophthora palmivora and Fusarium oxysporum were isolated and identified from ‘Big Blue’ Liriope symptomatic plants taken from the nursery and landscape. The pathogens were positively identified by morphological features of the pathogens and then confirmed with polymerase …
Motion Analysis Of Biotin Carboxylase-Driven Robotic Nano-Swimmers, Sima Hannani
Motion Analysis Of Biotin Carboxylase-Driven Robotic Nano-Swimmers, Sima Hannani
LSU Master's Theses
The purpose of this study is to experimentally validate the hypothesis that the enzyme biotin carboxylase (BC) can behave as a bimolecular motor and propel nano-scale particles in fluidic environments. This hypothesis was proposed in the M.S. thesis “Toward the Development of Biotin Carboxylase Driven Robotic Nano-swimmer” by Rachel Yates (Yates, 2012). In (Yates, 2012), the nano-particle (called a nano-swimmer) is a Janus particle with BC molecules attached to one hemisphere. The idea is that in the presence of its substrates (i.e., fuel) BC will cause individual nano-particles to undergo non-Brownian motion by virtue of its conformational change. In order …
Three Year Assessment Of Nearshore Crude Oil Contamination In The Gulf Of Mexico Using Gulf Menhaden (Brevoortia Patronus) As An Indicator Species: Menhaden Watch, Gregory Michael Olson
Three Year Assessment Of Nearshore Crude Oil Contamination In The Gulf Of Mexico Using Gulf Menhaden (Brevoortia Patronus) As An Indicator Species: Menhaden Watch, Gregory Michael Olson
LSU Doctoral Dissertations
Approximately 4.9 million barrels of crude oil along with natural gas were released into the Gulf of Mexico (GoM) from April to July 2010 (Deepwater Horizon, DWH, spill). Impacts of this magnitude seldom occur in the GoM (Ixtoc I was the last spill close to this magnitude occurring in 1979), and one cannot predict when they will happen. Major constituents of concern found in crude oil are Polycyclic Aromatic Hydrocarbons (PAHs), which often have low volatility that allows for prolonged existence in the environment. PAHs are compounds of concern according to the United States Environmental Protection Agency (USEPA), with one …

Stress, Anxiety Symptomology, And The Need For Student Support Services For University Freshmen Of First-Generation Status, Low-Ses Backgrounds, And Those Registered With Disabilities, Kelly Dale Allison
LSU Master's Theses
Three populations of concern for professional social workers in higher educational settings include first-generation college students (FGCSs), students from low socio-economic (low-SES) backgrounds, and students with disabilities. As the national demand for degrees in higher education rises both socially and economically, the push for young adults’ postsecondary success becomes increasingly crucial. In college and university settings, a significant portion of students may be classified as FGCSs, low-SES, or may be registered with a disability. Examining these vulnerable populations within higher education settings, particularly regarding stress and anxiety symptomology, can help social workers recognize the social, developmental, and academic inhibitions that …
Insights Into 5-Lipoxygenase Active Site And Catalysis, Sunayana Mitra
Insights Into 5-Lipoxygenase Active Site And Catalysis, Sunayana Mitra
LSU Doctoral Dissertations
Leukotrienes are potent immune-modulatory compounds involved in the inflammatory response. 5-Lipoxygenase (5-LOX) is the enzyme that catalyzes the production of Leukotriene A4 (LTA4), which is further metabolized to pro- and anti-inflammatory compounds derived from the substrate Arachidonic Acid (AA), a polyunsaturated fatty acid. The crystal structure of a stabilized form of 5-LOX has been recently reported (Gilbert, Bartlett et al. 2011). However, the structure does not reveal the mode of substrate entry or recognition. The first step in the enzymatic reaction involves the removal of a hydrogen from the central carbon of a pentadiene present in the substrate. It is …

Communicating Sustainability With Visuals: Issue Perception And Issue Engagement, Zeynep Melis Altinay
LSU Doctoral Dissertations
Today the list of environmental disasters threatening lives and natural resources has expanded to include many causes. Even though sustainable solutions have never been so urgent, public still issues low priority to many of these serious threats. Many impacts of environmental deprivation, such as coastal land loss, are invisible to the untrained eye, causing individuals to distance themselves psychologically from the risks. The slow pace of environmental degradation constitutes one of the biggest challenges in sustainability communication. The success of sustainable development will require the public to undergo a significant shift in thinking about environmental issues. This dissertation systemically investigates …
Stimulation Of Escherichia Coli Dna Damage Inducible Dna Helicase Ding By The Single-Stranded Dna Binding Protein Ssb, Zishuo Cheng
Stimulation Of Escherichia Coli Dna Damage Inducible Dna Helicase Ding By The Single-Stranded Dna Binding Protein Ssb, Zishuo Cheng
LSU Doctoral Dissertations
We investigate the regulation of an E.coli iron-sulfur protein DNA damage inducible DNA helicase (DinG) by single-stranded DNA binding protein (SSB). We find that SSB can form a stable protein complex with DinG and stimulate the DinG DNA helicase activity. On the other hand, SSB mutant that retains the single-stranded DNA binding activity but fails to form a protein complex with DinG becomes a potent inhibitor for the DinG DNA helicase. The results indicate SSB stimulates the DinG DNA helicase activity via direct protein-protein interaction. The results from these studies suggest that iron-sulfur proteins are regulated not only by intracellular …
Effects Of Light Quality And Light Quantity On The Growth Kinetics Of A Louisiana Native Microalgal/Cyanobacterial Co-Culture, Jonathan Zell Barnett
Effects Of Light Quality And Light Quantity On The Growth Kinetics Of A Louisiana Native Microalgal/Cyanobacterial Co-Culture, Jonathan Zell Barnett
LSU Master's Theses
One of the most important factors controlling the growth of microalgae is light. Light quality and light quantity have a dramatic effect on the production of biomass, lipids and pigments of microalgae. In this research, a native Louisiana co-culture containing Chlorella vulgaris (microalgae) and Leptolyngbya sp (cyanobacteria) was studied to determine the effects of various wavelength distributions and irradiance levels on growth kinetics. Growth rates, biomass levels, lipid contents and chlorophyll-a production was examined in batch cultures to determine which color light was optimum for cultivation. At 80 µmol/m^2-sec the species shifted from microalgae dominant to cyanobacteria dominant. The impact …
