Leveraging The Genomic Tools To Explore The Molecular Basis Of Salinity Tolerance In Rice And Soybean, Rajat Pruthi Jul 2024

Leveraging The Genomic Tools To Explore The Molecular Basis Of Salinity Tolerance In Rice And Soybean, Rajat Pruthi

LSU Doctoral Dissertations

Salinity stress significantly challenges agricultural productivity, particularly affecting major crops like rice and soybean. This research investigates the genetic basis of salt tolerance in both crops through high-resolution genetic mapping, genome-wide association studies (GWAS), and RNA-Seq analysis. In rice, we examined quantitative trait loci (QTLs) associated with salt tolerance at the seedling and flowering stages using a population of advanced backcrossed introgression lines (ILs). A genetic map, constructed with 14,230 polymorphic SNP markers, identified distinct QTLs and candidate genes for salt tolerance at both stages, suggesting differential genetic controls. Notable genes such as OsHAK13 and OsCYP21-4 were upregulated under salt …


The Role Of Sexual Network Core Groups In Disease Epidemics, Jason Janeaux Jul 2024

The Role Of Sexual Network Core Groups In Disease Epidemics, Jason Janeaux

LSU Doctoral Dissertations

Sexually transmitted infections (STIs) remain an economic and social burden, non-discriminately affecting sexually active individuals worldwide. The unique transmission of STIs is dependent upon host and pathogen life histories, as well as the underlying network structure of the host population. Within a population there is a group of individuals, the core group, that maintains STI presence and helps sustain ongoing transmission both within the core group and in the surrounding population. While the presence of these core groups is well documented, the criteria for inclusion into a sexual core group is not. In this dissertation, I explore common factors that …


Digital Agriculture Applications In Maize Nutrient Management And Soybean Crop Stands Assessment, Bhawana Acharya Jul 2024

Digital Agriculture Applications In Maize Nutrient Management And Soybean Crop Stands Assessment, Bhawana Acharya

LSU Master's Theses

High soil moisture from frequent excessive precipitation can reduce maize (Zea mays L.) yield and increase nitrogen (N) loss. Early-stage soybeans (Glycine max) are also susceptible to damage under these conditions. Traditional methods for assessing N status in maize and plant stands in soybean are labor-intensive and time-consuming. In this study, UAV remote sensing was used to assess maize N status under different N rates and excessive soil moisture. For soybeans, we compared a blob detection method with the YOLOv8 model to estimate plant density using ground images from a handheld camera. Additionally, YOLOv8 performance was evaluated …

Although extensively studied in cutaneous epithelial neoplasms, the TRPS1 immunoreactivity in cutaneous mesenchymal neoplasms and tumors of uncertain differentiation (CMNTUDs), such as atypical fibroxanthoma (AFX), remains largely unexplored. We assessed TRPS1 immunoreactivity in 135 CMNTUDs, comprising 46 fibrohistiocytic/fibroblastic tumors, 28 vascular tumors, 24 peripheral nerve sheath tumors (PNSTs), 21 tumors of uncertain differentiation, and 16 smooth muscle tumors. Additionally, we included selected cases of melanoma with spindled cell morphology or desmoplastic features (n = 9) and sarcomatoid squamous cell carcinoma (SSCC) (n = 5) to compare TRPS1 expression patterns with those of AFX. TRPS1 expression was prevalent in dermatofibromas (24/24), …

Nrg Oncology And Particle Therapy Co-Operative Group Patterns Of Practice Survey And Consensus Recommendations On Pencil-Beam Scanning Proton Stereotactic Body Radiation Therapy And Hypofractionated Radiation Therapy For Thoracic Malignancies, Wei Liu, Hongying Feng, Paige A Taylor, Minglei Kang, Jiajian Shen, Jun Zhou, Nathan Y Yu, Terence S Sio, Pranshu Mohindra, Joe Y Chang, Jeffrey D Bradley, Ying Xiao, Charles B Simone, Liyong Lin

Faculty, Staff and Student Publications

Stereotactic body radiation therapy (SBRT) and hypofractionation using pencil-beam scanning (PBS) proton therapy (PBSPT) is an attractive option for thoracic malignancies. Combining the advantages of target coverage conformity and critical organ sparing from both PBSPT and SBRT, this new delivery technique has great potential to improve the therapeutic ratio, particularly for tumors near critical organs. Safe and effective implementation of PBSPT SBRT/hypofractionation to treat thoracic malignancies is more challenging than the conventionally fractionated PBSPT because of concerns of amplified uncertainties at the larger dose per fraction. The NRG Oncology and Particle Therapy Cooperative Group Thoracic Subcommittee surveyed proton centers in …

Adenoid cystic carcinoma (ACC) is a rare, usually slow-growing yet aggressive head and neck malignancy. Despite its clinical significance, our understanding of the cellular evolution and microenvironment in ACC remains limited. We investigated the intratumoral microbiomes of 50 ACC tumor tissues and 33 adjacent normal tissues using 16S rRNA gene sequencing. This allowed us to characterize the bacterial communities within the ACC and explore potential associations between the bacterial community structure, patient clinical characteristics, and tumor molecular features obtained through RNA sequencing. The bacterial composition in the ACC was significantly different from that in adjacent normal salivary tissue, and the …

Neuroblastoma (NB) is a cancer of the peripheral nervous system found in children under 15 years of age. It is the most frequently diagnosed cancer during infancy, accounting for ~12% of all cancer-related deaths in children. Leucine-rich repeat-containing G-protein-coupled receptor 5 (LGR5) is a membrane receptor that is associated with the primary tumor formation and metastasis of cancers in the gastrointestinal system. Remarkably, high levels of LGR5 are found in NB tumor cells, and high LGR5 expression is strongly correlated with poor survival. Antibody-drug conjugates (ADCs) are monoclonal antibodies that are covalently linked to cell-killing cytotoxins to deliver the payloads …


Revisionary Taxonomy Within The Acmaeoderini, Joel Dubois Jul 2024

Revisionary Taxonomy Within The Acmaeoderini, Joel Dubois

LSU Master's Theses

The jewel beetles (Coleoptera: Buprestidae) are the 8th largest family of beetles and fill various important ecological roles including decomposers, pollinators, and leaf miners. The cosmopolitan buprestid tribe Acmaeoderini is extremely diverse, with more than 700 species across 14 genera. Historically, the acmaederines from Afro-Eurasia have received thorough morphological treatment and nearly all species from these areas have been separated into various genus and subgenus groupings. Contrastingly, past studies in the Americas have been mostly restricted to alpha-level taxonomic descriptions, and only a very small percentage of species are placed into any formal group. The aim of this study was …


Set-Based Tests For Genetic Association Studies With Interval-Censored Competing Risks Outcomes, Zhichao Xu, Jaihee Choi, Ryan Sun Jul 2024

Set-Based Tests For Genetic Association Studies With Interval-Censored Competing Risks Outcomes, Zhichao Xu, Jaihee Choi, Ryan Sun

Faculty, Staff and Student Publications

Over the past decade, massive genetic compendiums such as the UK Biobank have gathered extensive genetic and phenotypic data that hold the potential to provide unparalleled insight into the genetic etiologies of various complex diseases. However, much of the disease information is collected as time-to-event outcomes in interval-censored form, and conventional tools for genetic association analysis are often not available for this type of data. For example, set-based inference for common and rare variants analysis is a fundamental investigation in germline genetics studies, but there is a lack of approaches that can perform set-based testing when the interval-censored outcome of …

Turkish Journal of Botany

During studies on the taxonomical delimitation of some species of Funalia, some inconsistencies were observed in the genus. Based on morphological and phylogenetic analyses, Fomitella supina was positioned within the Funalia clade, thus the synonymization of the genus and the new combination of F. supina are proposed. Funalia glabrorigens is also combinated in the genus, while Coriolopsis hainanensis is suggested as a synonym of F. floccosa and F. rigida is assumed as a distinct species from F. floccosa. A table with morphological comparison of the 10 Funalia species confirmed by molecular analyses is also presented.

The rebound-competent viral reservoir, composed of a virus that is able to persist during antiretroviral therapy (ART) and mediate reactivation of systemic viral replication and rebound viremia after ART interruption (ATI), remains the biggest obstacle to treating HIV infection. A better understanding of the cellular and tissue origins and the dynamics of viral populations that initiate rebound upon ATI could help develop therapeutic strategies for reducing the rebound-competent viral reservoir. In this study, barcoded simian immunodeficiency virus (SIV), SIVmac239M, was used to infect rhesus macaques to enable monitoring of viral barcode clonotypes contributing to virus detectable in plasma after ATI. …


Gene Expression Analysis Reveals Dysregulation In Traumatic Brain Injury Leading To Tauopathy, Kristina M. Tosi Jul 2024

Gene Expression Analysis Reveals Dysregulation In Traumatic Brain Injury Leading To Tauopathy, Kristina M. Tosi

USF Tampa Graduate Theses and Dissertations

Traumatic Brain Injury (TBI) causes a cascade of detrimental events within neurons, contributing to a host of neurological diseases relating to dementia. In this study we have performed a meta-analysis comparing differentially expressed genes (DEG) in specific cell types such as neurons and microglia revealing inflammation as a common driver of neurological deficiencies post TBI. Inflammation and hypoxia are well characterized features of TBI; however, the molecular mechanisms causing tau hyperphosphorylation by tauopathy associated genes (TAG) post-TBI are currently poorly understood. Furthermore, there are limited in-vitro neuroinflammatory models that mimic primary and secondary TBI. We hypothesize that inducing hypoxia and …

Role Of Sds-22/Pp1 Phosphatase In Polarizing The Germplasm Of Caenorhabditis Elegans Embryo, Aparna Nurni Ravi Jul 2024

Role Of Sds-22/Pp1 Phosphatase In Polarizing The Germplasm Of Caenorhabditis Elegans Embryo, Aparna Nurni Ravi

Dartmouth College Ph.D Dissertations

During asymmetric cell division, cell polarity and cell cycle are tightly coupled to ensure robust segregation of cell fate determinants and generation of cellular diversity. In the one-cell C. elegans embryo, multiple cell cycle kinases regulate cell polarization and posterior segregation of germline fate determinants (germplasm). For example, PLK-1 kinase inhibits the retention of its germplasm substrate POS-1 in the anterior, driving POS-1 segregation to the posterior (Han et al., 2018). Additionally, MBK-2 kinase disassembles P granules in the anterior through phosphorylation of the P granule scaffold MEG-3, helping to drive P granule segregation to the posterior (Wang et al., …

Functional And Structural Analysis Of The Neimann-Pick Disease Type C Pathway To Include Caveolin-1, Anthony Michael Seat

Chemistry and Chemical Biology ETDs

Human disease is often thought of as an all or nothing prospect, either one has the disease or one does not. This does not bear out in clinical or personal experiences, instead demonstrating that disease occurs within a spectrum ranging from presumed unaffected to demonstrably and detrimentally affected.Neimann-Pick disease is one example of this spectrum look into diseased states, with multiple named versions of a phenotypically similar disease. We focus on Neimann-Picktype C (NPC), which is the result of a disruption in the efflux of cholesterol and sphingolipids from the endocytic pathway. NPC demonstrates this concept of a spectrum of …

Leucaena is a versatile legume shrub/tree used as tropical livestock forage and in timber industries, but it is considered a high environmental weed risk due to its prolific seed production and broad environmental adaptation. Interspecific crossings between Leucaena species have been used to create non-flowering or sterile triploids that can display reduced weediness and other desirable traits for broad use in forest and agricultural settings. However, assessing the success of the hybridisation process before evaluating the sterility of putative hybrids in the target environment is advisable. Here, RNA sequencing was used to develop breeding markers for hybrid parental identification in …

Background: The overall landscape of health-related quality of life (HRQoL) has not been thoroughly investigated in adolescents and young adults (AYAs) with cancer. Data are also lacking on how well HRQoL at the time of cancer diagnosis can prognosticate long-term survival in AYA survivors.

Patients and methods: We included 3,497 survivors of AYA cancer (age 15-39 years at diagnosis) who completed the Short-Form 12 Health Survey (SF-12) HRQoL questionnaire at diagnosis. Physical component summary (PCS) and mental component summary (MCS) scores were generated, with scores < 50 representing poor HRQoL. Differences in HRQoL by patient characteristics and tumor type were investigated using violin plots and t tests/analysis of variance. The effect of HRQoL on overall survival was assessed using Kaplan-Meier plots and Cox proportional hazards models.

Results: Overall mean PCS and MCS scores in this racially/ethnically diverse cohort (64% White, 19% …
