Mhc Gene Analysis And Immune Variation In Lepidodactylus Lugubris (The Mourning Gecko), Helen T. Vu Oct 2025

Mhc Gene Analysis And Immune Variation In Lepidodactylus Lugubris (The Mourning Gecko), Helen T. Vu

2025 Fall Honors Capstones Projects - Archive

The major histocompatibility complex (MHC) plays a central role in vertebrate immune defense by enabling pathogen recognition and initiating adaptive immune responses. While MHC diversity has been extensively studied in sexually reproducing species, comparatively little is known about its evolution in asexual lineages. The parthenogenetic gecko Lepidodactylus lugubris provides a unique opportunity to investigate how clonality and hybrid origins influence immune gene diversity. By leveraging whole-genome data, this study overcomes the limitations of previous transcriptome-based analyses and provides a more comprehensive view of MHC diversity in a clonal vertebrate. As the first step towards understanding MHC evolution in parthenogenetic lizards, …


Exploring The Role Of Ecological Traits In Shaping Spatial Patterns Of Genetic Diversity, Rilquer Mascarenhas Da Silva Sep 2025

Exploring The Role Of Ecological Traits In Shaping Spatial Patterns Of Genetic Diversity, Rilquer Mascarenhas Da Silva

Dissertations, Theses, and Capstone Projects

The field of comparative phylogeography aims at uncovering common underlying causes for shared patterns of diversity and diversification at the population level. However, it is now widely accepted that intraspecific genetic diversity patterns can differ considerably across co-occurring taxa due to ecological processes acting at the population level (and influencing individual movement and abundance). To model the processes underlying lineage diversification and demographic shifts in response to environmental changes, phylogeographers and population geneticists are now faced with the challenge of incorporating measurements of species ecological traits into their molecular studies. This dissertation aimed at investigating how different types of ecological …

Department of Animal Science: Dissertations, Theses, and Student Research

Project 1 focused on the central role that mitochondria play in ATP production, highlighting that variation within the mtDNA may influence feed efficiency. Variation in the mitochondrial genome was uncovered, and associations with feed efficiency in beef cattle were identified. Growth and feed intake phenotypes, as well as low-pass sequencing, were collected on beef steers across two populations. Protein coding variants were identified and used to classify animals into mitochondrial haplotypes. A linear mixed model was employed, which detected a significant association between mitochondrial haplotype and DMI. A significant haplotype with a variant in Complex I was associated with reduced …


Selecting For Less: How Much Methane Can We Truly Breed Away?, Sean B. Crowley Jun 2025

Selecting For Less: How Much Methane Can We Truly Breed Away?, Sean B. Crowley

ORBioM (Open Research BioSciences Meeting)

Background

Genetic selection has potential to reduce enteric methane emissions from cattle, but a key challenge is determining how much of the genetic variation in methane traits is independent of traits already targeted in breeding programs, such as feed intake and growth.

Methods

Methane and carbon dioxide emissions were recorded in 1,700 crossbred, indoor-fed beef cattle using Greenfeed systems. Performance data included feed intake, metabolic liveweight, average daily gain, carcass weight, and ultrasound and skeletal traits. Genetic parameters and correlations among traits were estimated using animal linear mixed models to quantify the independence of methane-related genetic variation.

Results

Daily methane …


Exploiting Genomics To Advance Genetic Gain For Reproductive Traits In Sheep, Mujibur Rahman Jun 2025

Exploiting Genomics To Advance Genetic Gain For Reproductive Traits In Sheep, Mujibur Rahman

ORBioM (Open Research BioSciences Meeting)

Poor reproductive performance has a negative impact on the profitability of sheep production systems with the number of lambs reared highlighted as a key driver of farm profitability. Nevertheless, the genetic improvement of reproductive traits in sheep has been constrained by their low heritability and pleiotropic nature. Understanding the underlying genetic architecture can improve genomic prediction estimates and enhance genetic gain.

This study will utilize large-scale genomic and phenotypic datasets to enhance genetic gain in sheep reproductive traits through four approaches: 1) to determine the effect of inbreeding depression on reproduction, 2) to identify causal variants impacting reproductive performance through …


Individual, Social, And Environmental Factors Associated With Patterns Of Parasitic Infection In Capuchin Monkeys (Cebus Imitator), Megan C. Henriquez Jun 2025

Individual, Social, And Environmental Factors Associated With Patterns Of Parasitic Infection In Capuchin Monkeys (Cebus Imitator), Megan C. Henriquez

Dissertations, Theses, and Capstone Projects

Parasites, and the infectious diseases they carry, are thought to have significantly impacted our evolutionary trajectory for millennia. Exploring how parasites are acquired and transmitted by their hosts in wild, natural populations is integral to understanding how similar processes may have shaped host-parasite co-evolutionary relationships over time. However, parasitological studies in humans and in non-human primates have produced inconsistent results, highlighting the dynamic, nuanced, and unique relationships individual parasites have with their hosts. These relationships are largely regulated by variation in factors at host, social, and environmental levels. Characteristics unique to the host (e.g., age and sex), factors pertaining to …


Rapid Identification Of Ambystoma Mexicanum Genotype Using Pcr Techniques, Elizabeth C. Dean May 2025

Rapid Identification Of Ambystoma Mexicanum Genotype Using Pcr Techniques, Elizabeth C. Dean

Undergraduate Honors Thesis Projects

Ambystoma mexicanum is an aquatic salamander species, commonly known as the axolotl, native to Mexico that is widely researched all over the world. In the wild, these salamanders have brown/black colored skin due to the presence of melanophores and xanthophores with shiny spots due to iridophores. In captivity, however, there are multiple different color morphs (phenotypes) of axolotls including leucistic, melanistic, and copper. Melanoid axolotls have black skin made by mostly melanophores, little xanthophores, and no iridophores. Melanistic genotypes such as melanoid and wild type color morphs are thought to be controlled by a single gene called Leukocyte Tyrosine Kinase …

The Design, Construction, And Testing Of Mrna Vaccine Against Equine Herpes Virus, Bhawana Devkota Mar 2025

The Design, Construction, And Testing Of Mrna Vaccine Against Equine Herpes Virus, Bhawana Devkota

LSU Master's Theses

Equine Herpesvirus-1 (EHV 1) is a worldwide significant pathogen that causes respiratory illness, abortion, and neurological disorders in equine. Current vaccines, including live attenuated, inactivated, and subunit platforms, do not prevent viral latency, mucosal shedding, or cross-strain immunity, requiring alternative approaches. To address these gaps, this project explores the design, synthesis, and in vitro testing of an mRNA vaccine targeting immunogenic EHV 1 glycoprotein (gB, gC, gD, gG, and gM). Epitopes were computationally predicted using the Immune Epitope Database (IEDB), codon-optimized for Bos taurus, and cloned into pUCIDT vectors using SP6/T7 promoters. In vitro transcription (IVT) used nucleotide modifications …
