Optimizing Citriculture In South Texas With Endemic Hlb, Ruth Lilia Galan

Theses and Dissertations

The Texas citrus industry has a long history of resilience, rebounding from environmental and economic disasters. Over the last decade it has endured several hurricanes, freezes, pests and diseases. Huanglongbing (HLB), a graft-transmissible disease caused by Gram-negative bacterium Candidatus Liberibacter asiaticus which is vectored by the Asian citrus psyllid (ACP) (Diaphorina citri Kuwayama), is an endemic citrus disease posing serious threat to the long-term viability of the industry. Rapid production of high quality nursery trees and effective protection of young citrus transplants from HLB are critical for long term sustainability of citriculture in this region. Studies were performed to improve …

The Effect Of Drought On Avian Migratory Patterns And Stopover Through Texas And Louisiana, Ian Becker

Theses and Dissertations

Extreme weather events pose a massive threat for native ecosystems. As precipitation and temperature patterns are altered due to climate change, drought may become an incredibly severe event on the landscape. Drought directly impacts resources that migratory birds need during stopover en route to breeding and non-breeding grounds. Here, I quantify the impacts of drought on migration through Texas and Louisiana using 26 years of weather surveillance radar data. To understand how drought interacts with the local environment to impact migration, I tested 4 hypotheses displaying drought’s ability to impact migrants in conjunction with climatic and habitat level characteristics. Fall …

Developing A Qpcr Method For Evaluating Parasitoid Wasps As A Potential Means Of Control Of The Southern Cattle Fever Tick Rhipicephalus (Boophilus) Microplus In South Texas, Abbey Abalos

Theses and Dissertations

Ixodiphagus spp. wasps are natural enemies of ticks that have been reported to cause mortality in multiple tick species. Parasitoid wasps may represent a potential biocontrol alternative to traditional chemical tick control methods, which are challenged by non-target toxicity and the development of pesticide resistance in species of concern such as Rhipicephalus microplus, a pest of livestock that causes billions of dollars in loss to the livestock industry worldwide. Rhipicephalus sanguineus s.l. is a congeneric species of R. microplus, and parasitism of R. sanguineus by Ixodiphagus sp. in areas of co-occurrence has been observed. It is unknown if R. microplus …

The Impact Of Nutrition On Insecticide Resistance And Gene Expression In Aedes Aegypti, Esmeralda Guadalupe Rosas

Theses and Dissertations

The development of insecticide resistance in Aedes aegypti, a major vector of dengue and Zika viruses, threatens vector control efforts, particularly in endemic regions such as South Texas. Insecticides remain widely used; however, their overuse has accelerated metabolic resistance mediated by cytochrome P450 enzymes. Environmental factors such as larval nutrition may influence mosquito physiology and resistance-associated gene expression, yet this relationship remains poorly understood. This study examines how larval nutritional conditions affect the expression of cytochrome P450 genes linked to pyrethroid resistance in Aedes aegypti. Larvae were reared under five dietary treatments differing in lipid and protein ratios, and adults …

Investigating The Ability Of Foxo1 To Maintain Stem Cells, Stella Aime Rios

Theses and Dissertations

Forkhead box O (Foxo) transcription factors are key regulators of stem cell identity and tumor aggressiveness. Prior work from our group and others demonstrates that Foxo factors maintain stem-like states across diverse biological systems; however, the mechanisms by which Foxo1 suppresses differentiation remain poorly defined.

Using C2C12 myoblasts as a model, we investigated whether Foxo1 preserves stem-like programs through regulation of the nuclear pore protein Nup210. RNA interference was used to generate Foxo1 knockdown cells, followed by qRT-PCR, RNA-sequencing, and fluorescence microscopy. Transcriptomic analysis revealed widespread gene expression changes involving metabolic, mitochondrial, and transcriptional pathways. Notably, Nup210 expression was significantly …

Bacillus Subtilis Parb C-Terminal Lysine Residues Are Essential For Dimerization And In Vivo Function, Indicating Their Roles In Dna Sliding, Aleksey Aleshintsev, Lindsey E. Way, Ngoc Khanh Lai, Bianca Guerra, Paloma Dorantes, Lois Akosua Serwaa, Sealtiel Anulao, Miranda Molina, Xindan Wang, Hyeongjun Kim

Physics & Astronomy Faculty Publications

The broadly conserved ParB protein performs crucial functions in bacterial chromosome segregation and replication regulation. The cellular function of ParB requires it to dimerize, recognize parS DNA sequences, clamp on DNA, then slide to adjacent sequences through nonspecific DNA binding. How ParB coordinates nonspecific DNA binding and sliding remains elusive. Here, we combine multiple in vitro biophysical and computational tools and in vivo approaches to address this question. We found that five conserved lysine residues in the C-terminal domain (CTD) of ParB play distinct roles. While the two central rigid lysine residues provide the structural platform for the CTD, the …

Weather Conditions Associated With Citrus Canker Incidence Caused By Aw Strain In The Lower Rio Grande Valley Of South Texas, Amit Sharma, Teresa Patricia Feria-Arroyo, George Yanev, Madhurababu Kunta

School of Integrative Biological & Chemical Sciences Faculty Publications

Citrus canker, caused by bacterium Xanthomonas citri subsp. citri (Xcc), affects the citrus industry by making the fruit unmarketable due to unsightly lesions on the fruit. Citrus canker caused by a relatively new AWstrain of Xcc was reported on the citrus trees in the residential areas of the Lower Rio Grande Valley (LRGV) of South Texas. Xcc AW has a limited host range, predominantly affecting limes and a few other citrus species. Previous work has reported prevailing environmental conditions that influence the incidence and spread of the citrus canker caused by the Asiatic A strain. However, no information is available …

Spatiotemporal Analysis Of Genetic Perturbations Reveals A Genetic Cascade Driving Tribolium Gap Gene Initialization, Mahla Ahmadi, Heike Rudolf, Christine Mau, Jimena Garcia-Guillen, Ezzat El-Sherif

School of Integrative Biological & Chemical Sciences Faculty Publications

The ‘French flag’ model has long served as the prevailing framework for explaining how morphogen gradients generate spatial domains during embryonic development. However, recent evidence indicates that many tissues establish patterns by translating the sequential activation of genes into spatial domains. While the sequential nature of this process is becoming clear, the mechanisms that mediate these temporal dynamics and translate them into stable spatial boundaries remain debated. Using the gap gene network in the flour beetle Tribolium castaneum [which mediates the regionalization of the anterior-posterior (AP) axis into different axial fates through the regulation of downstream Hox genes] as a …

Modern guidelines emphasize individualized, team-based revascularization …

Synthesis Of Antibody Functionalized Polyaniline/Polystyrene/N-Gqds Composite Fibermats For Sweat Based Cortisol Biosensing Applications, Ashwin James

Honors Theses

Noninvasive, wearable biosensors capable of detecting stress biomarkers in sweat require electrodes that are flexible, conductive, insoluble in water, and highly sensitive at low concentrations of analyte. In this work, bovine serum albumin blocked and anti-cmab immobilized nitrogen doped graphene quantum dots integrated polyaniline/polystyrene composite fibermat electrodes (BSA/Anti-Cmab/N-GQDs/PANI/PS electrodes) were synthesized and evaluated as a potential platform for an electrochemical cortisol biosensor in sweat based systems. Polyaniline was utilized in order to provide electrical conductivity, while polystyrene served as a carrying polymer for mechanical support and its hydrophobicity. Composite fibermats were manufactured through Forcespinning™, followed by a secondary polyaniline graft …

Probing Prebiotic Rna Oligonucleotide Polymerization On A Mg-Fes Catalyst Using Microfluidics, Gabriella Garza

Theses and Dissertations

Non-enzymatic polymerization under aqueous conditions has long been viewed as unfavorable, due to product (H2O) inhibition in abiotic settings (Damer & Deamer, 2015); despite its efficiency in biology through ATP monomer activation. Geochemically sustained pH gradients may provide free energy for condensation of organic monomers (Martin & Russell, 2003). Here, we investigated a biologically analogous non-enzymatic mechanism for RNA oligomerization, by probing the catalytic properties of a Mg-rich FeS mineral under aqueous conditions. FeS minerals promote a diverse prebiotic reaction (Wächtershäuser, 1988) and would have precipitated at Hadean submarine hydrothermal systems (Sojo et al., 2016). Natural pH and redox gradients …

Applicability Of Cementochronology To Estimate Season-Of-Death In Humans: Insights From Modern Documented Collections, Olga Ibarra-Sanchez

Theses and Dissertations

Dental cementum is characterized by lifelong deposition of alternating opaque annuli in fall/winter and translucent bands in spring/summer. This study aims to test the applicability of cementochronology to estimate season-of-death, by observing the properties of the last layer, with direct implications for forensic anthropology and bioarchaeology. The sample includes canine teeth from 146 adults (84 males, 62 females), age-at-death ranging from 20-97 years (mean=61.7 years, SD=18.6 years), from two contemporary skeletal collections. Of these individuals, 78 (53.4%) died in spring/summer and 68 (46.6%) died in fall/winter. Overall accuracy was low at 64.4% (94/146). Accuracy was higher for spring/summer deaths 100.0% …

Testing Microscopic Approaches For Cementochronology In The 21st Century Identified Skeletal Collection, Portugal, Amando Luis Montalvo Jr.

Theses and Dissertations

Age-at-death estimation is a key component to the creation of a biological profile in forensic anthropology. Acellular extrinsic fiber cementum annulations have been shown to correlate with chronological age. Cementochronology examines this correlation through the sum of the alternating translucent bands and opaque annuli, and the age of eruption of a tooth. While several microscopy techniques have been used, there is no consensus on the most optimal. This study will assess the reliability, precision and accuracy of three microscopy techniques: Brightfield (BF), Phase Contrast (PC) and Differential Interference Contrast (DIC). PC was the most reliable (rTEM= 10.4%), the most precise …

Assessment Of Floral Resources From Three Tamaulipan Thornscrub Communities Of The Lower Rio Grande Valley, Gracie Makenna Granados

Theses and Dissertations

The Tamaulipan thornscrub is a transition zone between the neotropics and the temperate regions, harboring high biodiversity. This habitat supports a diverse insect community, including many pollinators of native and cultivated plants in Texas and northeastern Mexico. This ecosystem has been extensively degraded and lost; only 5% of its original cover remains north of the Rio Grande. Restoration of the Tamaulipan thornscrub has been ongoing for over three decades, but the important roles of pollinators in the success of such efforts and the functioning of the restored ecosystem have rarely been considered in restoration efforts. The purpose of this study …

Opa1-Mediated Mitochondrial Dynamics In Myogenic Differentiation Of C2c12 Myoblasts, Daniel Eloy Bazan

Theses and Dissertations

Mitochondria play a pivotal role in metabolic energy production, cellular signaling, and apoptosis. To carry out these key cellular roles, mitochondria dynamically balance their organization through opposing including fusion and fission processes. The balance between mitochondrial fusion and fission is regulated by key proteins such as OPA1 (optic atrophy 1) and OMA1 (overlapping activity with metalloprotease). More recently, mitochondria have been increasingly revealed to play key roles in cellular differentiation, where metabolic demands are reprogrammed. This study aims to elucidate the specific roles of OPA1 and OMA1 in the differentiation of C2C12 myoblast cells into myotubes.

Our data demonstrates that …

Phenotypic Plasticity In Response To Abiotic Factors In Silverleaf Nightshade (Solanum Elaeagnifolium), And The Effectiveness Of North American Lacebug (Gargaphia Arizonica Drake And Calvo) As A Biocontrol, Marco Andre Silguero

Theses and Dissertations

Silverleaf nightshade (Solanum elaeagnifolium) is a widespread invasive weed in South Texas and other arid regions, where it reduces crop productivity, competes with native vegetation, and resists conventional control methods. Its ability to thrive across different environments is linked to phenotypic plasticity, allowing it to adjust growth and physiology in response to light and water availability. In this thesis, I examine the role of plasticity in S. elaeagnifolium under field conditions and evaluate the potential of the North American lacebug (Gargaphia arizonica) as a biological control agent. Field observations were used to measure plant traits such as height, stem thickness, …

Cucurbit Plant Defenses Against Aboveground Or Belowground Insect Herbivores Are Distinct And Shaped By Eco-Evolutionary Factors, Morgan N. Thompson, Emily M. Russavage, Jeremy G. Garces, B. Jack Bradford, Danielle Merrell, Charles P.-C. Suh, Anjel M. Helms

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Plant defense strategies against insect herbivores are classified broadly as resistance or tolerance. Resistance deters insect growth or feeding, while tolerance mitigates negative effects of herbivory on plant fitness. Plant investment into resistance or tolerance strategies likely falls along a continuum that has been shaped by eco-evolutionary factors, such as plant domestication or coexistence histories with herbivores. Relatively little is known about how general defense strategies differ against aboveground foliar herbivores and belowground root herbivores. In the current study, we investigated defense strategies of plant species in the gourd family (Cucurbitaceae) against aboveground squash bug (Anasa tristis) or …

Transformation With Genes To Improve Lipid Production And Barcoding To Identify Unknown Algal Species, Michelle T. Rada

Theses and Dissertations

With the rising demand for alternative fuels, algal-based biofuels are a promising, sustainable source that meets commercial interest while producing lower greenhouse gas emissions compared to fossil fuels. This thesis explored two studies, evaluating microalgae for their future potential in lipid yield for biofuel production.

The first study involved developing a cost-efficient electroporation protocol that allowed for the genetic transformation of Chlamydomonas reinhardtii using the pChlamy_4 vector, which supports future cloning of genes to enhance lipid production. Parameters affecting DNA uptake and integration into algal genomes were studied: the effect of cell density, the settings of the electroporation device, and …

Vibrio Cholerae Endemic To The Lower Rio Grande Delta Segregate Into Urban And Rural Phylotypes, Daniele Provenzano, Jeffrey W. Turner, Jorge Duran-Gonzalez, David A. Laughlin, David Silva, Viviana Trevino, Miguel F. Gonzales, Boris Ermolinsky, Stefan Pukatzki

School of Integrative Biological & Chemical Sciences Faculty Publications

The lifestyle of Vibrio cholerae is primarily environmental, yet a chance encounter with a human host can lead to cholera, a potentially lethal form of diarrhea. Strains belonging to O1 and O139 serogroups have pandemic potential, but the contribution of non-O1/non-O139 serovars towards the genesis of cholera remains unclear. Endemic V. cholerae lineages were investigated given several historical accounts describing cholera epidemics and sporadic, contemporary cholera-like outbreaks along the lower Rio Grande Delta (LRGD). Seven isolates were recovered from an urban segment of the Rio Grande and six from a rural segment where the river empties into the Gulf of …

Investigating The Threshold Of Opa1-Mediated Mitochondrial Fusion In Shsy5y Cells, Jorge Alberto Elizondo

Theses and Dissertations

Mitochondrial dynamics occurring under stress-induced conditions in SHSY5Y neuroblastoma cells provide insight into the OPA1-mediated mitochondrial fusion threshold in cells of varying energetic demands. Mitochondria are dynamic structures that are continuously balancing fusion and fission, depending on cellular needs. The ability to fuse and divide relies on the maintenance of the mitochondrial transmembrane potential. Stress-induced conditions in SHSY5Y cells were induced via utilization of carbonyl cyanide m-chlorophenylhydrazone (CCCP), a protonophore that disrupts the transmembrane potential. OMA1 protein reacts to the loss of transmembrane potential and subsequently cleaves the fusion-active isoforms of OPA1, L-OPA1. This causes an accumulation of S-OPA1, the …

Contributions Of Citizen Science Data To Butterflies Of The Lower Rio Grande Valley, Akane Jazmyn Benitez

Theses and Dissertations

Citizen science-provided insect data inherently exhibits variability in accuracy. In the Lower Rio Grande Valley (LRGV), butterfly occurrence reporting is predominantly reliant on citizen science contributions. My research compared fieldwork conducted monthly over a year to occurrence records submitted by visitors at the National Butterfly Center and in Mission, Hidalgo County, Texas. I hypothesized that butterfly occurrences at the Center would be maximized during the fall and minimized during winter and summer months. My research findings revealed that butterfly taxa richness is contingent upon the following factors: 1) the impact of citizen science submitting reports, and 2) monthly butterfly activity …

Kaiso Mediates Transcription And Rna Splicing In Colorectal Carcinoma: Role Of Brca1 In The Kaiso Enhanceosome, Weifeng Luo, Manish Kumar Tripathi, Qi Liu, Lei Chen, Robert W. Cowan, Juliet M. Daniel, Chi Yan, Ann Richmond, Albert B. Reynolds

School of Medicine Publications

Kaiso (ZBTB33) is a transcription factor involved in mitotic clonal expansion and tumorigenesis in association with Adenomatous Polyposis Coli (APC) loss of heterozygosity. ENCODE data show strong overlap of the Kaiso promoter-binding site—encode-derived Kaiso-binding site (eKBS) and many other transcription factors, including BRCA1. Here we sought to determine whether BRCA1 is a component of the Kaiso enhanceosome that regulates gene transcription. Using proximal ligation assays, immunoprecipitation followed by mass spectrometry, luciferase assays and ChIP-seq experiments, we evaluated the association between BRCA1 and Kaiso. Kaiso nuclear extract immunoprecipitation experiments revealed that Kaiso associates strongly with genes involved in RNA splicing and …

Assessing Illegal Take Of Sea Turtle In Bocas Del Toro, Panamanian Caribbean, Daniela Carolina Rojas-Cañizales

Theses and Dissertations

In Bocas del Toro, Panama, sea turtles were exploited for generations to supply local, national, and international markets. Today, sea turtle species are globally protected by different laws, and Panama is no exception. However, the use of sea turtles in Bocas del Toro and local perceptions regarding the consumption of these reptiles are unknown. Accordingly, during May of 2024, I conducted twenty-five semi-structured interviews with key informants selected by targeted and snowball sampling. Sea turtle consumption persists, and there is a clandestine network to sell turtle meat and derived products in Bocas del Toro. This study provides the first assessment …

Quantification Of Blue Carbon Within The Marine Animal Forest On The Rio Grande Valley Artificial Reef, Michelle Kathryn King

Theses and Dissertations

The protection and enhancement of coastal ecosystems provides a number of benefits such as heightened biodiversity, increased fisheries, and enhanced carbon capture (Yeemin et al., 2024). The study of blue carbon ecosystems has expanded rapidly in the last two decades since the term was coined in 2009 (Lovelock & Duarte, 2019). The most well-known blue carbon ecosystems include vegetation-dominated ecosystems such as seagrass meadows, salt marshes, and mangrove forests (Howard et. al., 2014). Prior studies have overlooked Marine Animal Forests (MAF) ability to capture carbon, until recent studies on soft coral (Coppari et al., 2019) and sponge (Rix et al., …

A Comparative Study Of Urban And Natural Nesting Gray Hawks In The Lower Rio Grande Valley Of South Texas, Evan Farese

Theses and Dissertations

Urbanization can negatively impact birds of prey, which occupy higher trophic levels. The Gray Hawk (Buteo plagiatus) is a neotropical raptor inhabiting the Lower Rio Grande Valley (LRGV) of Texas, where it is threatened. The species’ ecology has been little studied and it is unclear how urbanization may affect population viability. I studied Gray Hawk reproductive success, diet, and thermal ecology at nests in urban and natural habitats in the LRGV. Camera trap data showed adults at urban nests delivered mostly avian prey, while mammalian prey was most frequently brought to natural nests. Data from temperature loggers showed …

Melanaphis Sacchari/Sorghi Complex: Current Status, Challenges And Integrated Strategies For Managing The Invasive Sap-Feeding Insect Pest Of Sorghum, Alejandro Vasquez, Joseph Belsky, Neetu Khanal, Heena Puri, Devi Balakrishnan, Neelendra K. Joshi, Joe Louis, Glenn Studebaker, Rupesh Kariyat

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Melanaphis sacchari (Zehntner;Hemiptera: Aphididae), sugarcane aphid (SCA), is an invasive phloem-feeder found worldwide with a wide host range of economically important plants including sorghum and sugarcane. Given its high reproductive capacity and ability to rapidly spread over long distances, SCA presents challenges for effective control, leading to substantial economic losses. Recent studies have identified two multiloci SCA genotypes specialized in feeding on sugarcane (MLL-D) and sorghum (MLL-F) in the USA, which raises concerns as the USA is the second largest sorghum-producing country. This has encouraged research towards identifying these two biotypes where some research has stated them as two species; …

Darkwah, Aaron George, Sheema Khan, Nadeem Zafar, Santosh Kumar, Namita Sinha, Meena Jaggi, Subhash C. Chauhan

Research Symposium

Background: High-risk strains of HPV are known to cause cervical cancer. Multiple clinical studies have emphasized that smoking and drinking are critical risk factors for cervical cancer and its high-grade precursors. In this study, we investigated if smoking and/or drinking augment the molecular mechanisms of the cervical carcinogenesis and defined a potential therapeutic approach for their attenuation.

Methods: The impact of benzo[a]pyrene (B[a]P) and/or ethanol (EtOH) exposure on cervical cancer cells was assessed by measuring changes in their cell migration and invasion characteristics. Expression of HPV16 E6/E7, NF-κB, cytokines, and inflammation mediators was determined using qRT-PCR, immunoblotting, ELISA, luciferase reporter …

Novel Nanoformulation Of Piperlongumine Attenuates Pancreatic Tumor Desmoplasia And Modulates Tumor Immune Responses, Vivek K. Kashyap, Reinaldo Mandes, Neeraj Chauhan, Daniel Zubieta, Mohammed Sikander, Eswara N.H.K Ghali, Bilal B. Hafeez, Murali M. Yallapu, Subhash C. Chauhan

Research Symposium

Pancreatic cancer (PanCa) is characterized by a lack of early diagnosis, poor response to available therapeutic modalities, and chemoresistance. Gemcitabine (GEM) is currently considered the most effective therapy for PanCa; however, it shows only a marginal survival benefit of 6 months. This poor drug response has been attributed to desmoplasia, causes suboptimal drug delivery, alters tumor microenvironment (TME), which includes tumor surrounding blood vessels, fibroblasts, immune cells, extracellular matrix, and other signaling molecules and induces chemo-resistance in tumors. To overcome these existing issues associated with chemotherapy, the identification and development of novel therapeutic modalities are a pressing need. Piperlongumine (PL) …

Ormeloxifene-Mediated Attenuation Of Β-Catenin Signaling In Hepatocellular Carcinoma Progression, Mohammed Sikander, Shabnam Malik, Daniel Zubieta, Anyssa Rodriguez, Molly Vela, Sheema Khan, Fathi T. Halaweish, Murali M. Yallapu, Meena Jaggi, Subhash C. Chauhan

Research Symposium

Background: Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer, with approximately 41,000 new cases and 29,000 deaths annually in the U.S. The management of HCC poses significant challenges due to severe toxicity and inadequate responses to existing chemotherapeutic agents. Aberrant β-catenin signaling is recognized as a crucial factor influencing the differentiation grades of HCC patients. Therefore, there is an urgent need to identify more effective and non-toxic β-catenin inhibitors for cancer treatment. Notably, ormeloxifene (ORM), a clinically approved selective estrogen receptor modulator with a favorable therapeutic index, has demonstrated remarkable anticancer activity, making it a promising …

Trpv1 And Its Co‑Expressed Genes Are Associated With The Progression Of Hepatocellular Carcinoma, Bhuvnesh P. Sharma, Himanshu N. Singh, Sanjay Kumar, Deepak Verma, Deepak Parashar, Murali M. Yallapu, Everardo Cobos, Subhash C. Chauhan, Vivek K. Kashyap

Research Symposium

Background: Hepatocellular carcinoma (HCC) is the most common type of liver cancer. Transient receptor potential vanilloid 1 (TRPV1) is a nonselective Ca²⁺ channel protein widely expressed and plays a significant role in cancer initiation and progression. However, the biological significance of TRPV1 in HCC has not been systematically and comprehensively investigated. This study used deep data mining and transcriptomics analyses to describe the significance of TRPV1 expression and its association with HCC prognosis.

Methods: Download the RNA expression of TRPV1 from the Cancer Genome Atlas (TCGA), Genotype Tissue Expression Atlas (GTEx), Tumor Immune Estimation Resource (TIMER), and the UALCAN …
