The Differences Of Prokaryotic Pan-Genome Analysis On Complete Genomes And Simulated Metagenome-Assembled Genomes, Tang Li
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Metagenomic assembly is often used in microbiome research. In metagenomic assembly, contigs are binned based on the shared nucleotide composition. These contig bins are called metagenome-assembled genomes (MAGs), each representing a unique bacterial genome recovered from metagenome sequencing. Hundreds of thousands of high-quality MAGs of various ecological environments have been published since 2017, and increasingly more MAGs are being used in pan-genome analyses where unculturable species or species without reference genomes are studied in microbiome research. However, compared to the traditional pan-genome analysis that uses isolate genomes (from a pure strain isolated from a mixed bacterial population), it is not …

Sensitive And Specific Detection Of Sars-Cov-2 In Saliva Using Reverse Transcriptase Loop-Mediated Isothermal Amplification, Casey Juntila
All NMU Master's Theses
A novel coronavirus called SARS-CoV-2 has caused the emergency release of the most well-known molecular assay, the CDC N1 RT-PCR assay, causing reports of poor analytical performance resulting in false-negative results (20, 26), and inconsistent testing kits received (23, 32). An immediate and dire need for a rapid and reliable SARS-CoV-2 testing workflow specifically designed for a university setting is the purpose this project is aiming and intended to fulfill. The workflow design uses a less invasive saliva sample for rapid screening using colorimetric RT-LAMP detection of three SARS-CoV-2 gene regions for Orf1ab, envelope, and nucleocapsid. Purified SARS-CoV-2 genomic RNA …

Evaluation Of Horizontal Gene Transfer Between Genetically Engineered Cyanobacteria And Gram-Negative Bacteria, Andriana Chrysovalanti Zourou
Chemistry & Biochemistry Theses & Dissertations
As the world population is increasing and societies become more technology driven, there is an imperative to develop ‘green energy’ sources to protect our planet. Cyanobacteria that have been genetically engineered to produce organic compounds that may be burnt as fuels show great potential, as they are an environmentally friendly and self-renewable, net carbon-neutral option. However, there are potential risks in the development and use of genetically modified organisms (GMOs). We need to understand in advance the risks that GMOs may pose to our environment and to animal and human health. This will enable experimental procedures, containment strategies and policies …

A clear understanding of genetic diversity in weedy rice is important in improving protocols for its conservation, ex situ. To this end, Asian collections of weedy rice together with accessions of the wild AA genome species Oryza nivara Sharma et Shastry and Oryza rufipogon Griffith, and the cultivated species, Oryza sativa L. were characterized using 16 qualitative morphological traits and 18 SSR markers. The Shannon-Weaver index (H’) revealed higher diversity in the weedy (mean H’ = 0.76) and wild O. nivara (mean H’ = 0.79) and O. rufipogon samples (mean H’ = 0.69) compared to the cultivated …

Grain Yield Variations In Rice Genotypes Under Different Growing Environments In The Philippines, Kim Nyka C. Perdiguerra, Shiro Mitsuya, Akira Yamauchi, Felino P. Lansigan, Maria Victoria O. Espaldon, Jose E. Hernandez, Pompe C. Sta. Cruz
The Philippine Agricultural Scientist
Grain yield variations in PSB Rc18, NSIC Rc222 (inbreds) and NSIC Rc202H (hybrid) were determined across growing environments as a function of cropping seasons and locations in rice producing areas in the Philippines. Contribution of location to variation in grain yield is 61.0%, while 12.7% for the season, and 6.1% for the genotype and this must be due location by season by genotype interactions. Dry season cropping in Nueva Ecija produced the highest mean grain yield. On the other hand, wet season cropping in Davao del Sur produced the least mean grain yield. The genotypes differed in their response to …

Genetic Variability In Fusarium Oxysporum F. Sp. Vasinfectum Causing Damping-Off Of Cotton (Gossypium Barbadense L.) Seedlings [Research Note], Reda Helmy Sammour, Salah Abdel Moemen, Eman Elagamy
The Philippine Agricultural Scientist
The genetic variability of Fusarium oxysporum f. sp. vasinfectum isolates from Gossypium barbadense L. seedlings were assessed using pathogenicity, mycelial compatibility, and RAPD analyses. The results showed that the disease incidence percentages and compatibility percentages considerably varied, extending from 33.2 to 86.6 % and 6 to 60 %, respectively in North Egypt and from 33.3 to 66.6 % and 0.0 to 20% in South Egypt. It also showed that the isolates ISO-8 and ISO-19 had the lowest disease incidence (33.2%) as compared with isolate ISO-5 (86.6%). Results of the mycelial compatibility had a reversible relationship with disease incidence percentage. Cluster …

Faculty, Staff and Students Publications
Human heart failure, a leading cause of death worldwide, is a prominent example of a chronic disease that may result from poor cell renewal. The Hippo signaling pathway is an inhibitory kinase cascade that represses adult heart muscle cell (cardiomyocyte) proliferation and renewal after myocardial infarction in genetically modified mice. Here, we investigated an adeno-associated virus 9 (AAV9)–based gene therapy to locally knock down the Hippo pathway gene Salvador (Sav) in border zone cardiomyocytes in a pig model of ischemia/reperfusion-induced myocardial infarction. Two weeks after myocardial infarction, when pigs had left ventricular systolic dysfunction, we administered AAV9-Sav …

Telomeric And Sub-Telomeric Structure And Implications In Fungal Opportunistic Pathogens, Raffaella Diotti, Michelle Esposito, Chang Hui Shen
Publications and Research
Telomeres are long non-coding regions found at the ends of eukaryotic linear chromosomes. Although they have traditionally been associated with the protection of linear DNA ends to avoid gene losses during each round of DNA replication, recent studies have demonstrated that the role of these sequences and their adjacent regions go beyond just protecting chromosomal ends. Regions nearby to telomeric sequences have now been identified as having increased variability in the form of duplications and rearrangements that result in new functional abilities and biodiversity. Furthermore, unique fungal telomeric and chromatin structures have now extended clinical capabilities and understanding of pathogenicity …
Genome Wide Association Mapping Of Root Traits In The Andean Genepool Of Common Bean (Phaseolus Vulgaris L.) Grown With And Without Aluminum Toxicity, Daniel Ambachew, Matthew W. Blair
Genome Wide Association Mapping Of Root Traits In The Andean Genepool Of Common Bean (Phaseolus Vulgaris L.) Grown With And Without Aluminum Toxicity, Daniel Ambachew, Matthew W. Blair
Agricultural and Environmental Sciences Faculty Research
Common bean is one of the most important grain legumes for human diets but is produced on marginal lands with unfavorable soil conditions; among which Aluminum (Al) toxicity is a serious and widespread problem. Under low pH, stable forms of Al dissolve into the soil solution and as phytotoxic ions inhibit the growth and function of roots through injury to the root apex. This results in a smaller root system that detrimentally effects yield. The goal of this study was to evaluate 227 genotypes from an Andean diversity panel (ADP) of common bean and determine the level of Al toxicity …

Tree Establishment On Post-Mining Waste Soils: Species, Density, And Mixture Effects, Degi Harja Asmara, Suzanne Allaire, Meine Van Noordwijk, Damase P. Khasa
Aspen Bibliography
Tree establishment to restore degraded boreal post-mining lands is challenged by low soil productivity, a harsh microclimate, and potentially high contaminant levels. The use of mixed vegetation can facilitate the microclimate but increase competition for soil resources. A statistical accounting of plant–plant interactions and adaptation to multispecies conditions is hard to achieve in field experiments; trials under controlled conditions can distinguish effects of planting density and species interactions in the early stages of plant establishment. A greenhouse trial was established in containers (“mesocosms”) with waste rock or fine tailings from gold mines. Pregerminated (1-week-old) seedlings (Alnus viridis subsp. crispa …

Department of Biology Faculty Scholarship and Creative Works
While the desire to uncover the neural correlates of consciousness has taken numerous directions, self-face recognition has been a constant in attempts to isolate aspects of self-awareness. The neuroimaging revolution of the 1990s brought about systematic attempts to isolate the underlying neural basis of self-face recognition. These studies, including some of the first fMRI (functional magnetic resonance imaging) examinations, revealed a right-hemisphere bias for self-face recognition in a diverse set of regions including the insula, the dorsal frontal lobe, the temporal parietal junction, and the medial temporal cortex. In this systematic review, we provide confirmation of these data (which are …

Analysis Of Post-Traumatic Stress Disorder Gene Expression Profiles In A Prospective, Community-Based Cohort, Jan Dahrendorff
USF Tampa Graduate Theses and Dissertations
Post-traumatic stress disorder (PTSD) is a common and debilitating psychiatric disorder that may occur in individuals exposed to traumatic events such as accidents, interpersonal violence, war, combat-exposures or natural disasters. PTSD is a significant public health issue with a high disease burden associated with substantial health care costs and several comorbidities negatively affecting an individual’s quality of life. The biological underpinnings of the disorder are not well understood. Gene expression studies can shed light into the complex physiology of PTSD. However, to date, studies employing a hypothesis-free approach examining the whole transcriptome are scarce and are limited to assessment of …

Past human genetic diversity and migration between southern China and Southeast Asia have not been well characterized, in part due to poor preservation of ancient DNA in hot and humid regions. We sequenced 31 ancient genomes from southern China (Guangxi and Fujian), including two ∼12,000- to 10,000-year-old individuals representing the oldest humans sequenced from southern China. We discovered a deeply diverged East Asian ancestry in the Guangxi region that persisted until at least 6,000 years ago. We found that ∼9,000- to 6,000-year-old Guangxi populations were a mixture of local ancestry, southern ancestry previously sampled in Fujian, and deep Asian ancestry …
Literature Review Of Human Hdr Syndrome With Gata3 Haplo Insufficiency, Olivia Ambursley-Gries
Literature Review Of Human Hdr Syndrome With Gata3 Haplo Insufficiency, Olivia Ambursley-Gries
Honors Theses
This literature mining project is regarding mutations that cause hearing loss in patients with human hypo parathyroid, deafness, and renal dysplasia (HDR) syndrome caused by a mutation in the GATA3 gene. The disease is unique; not all diagnosed individuals present with all symptoms of the triad. Van Esh et al. found that the haploinsufficiency of the GATA3 is found on chromosome 10p14-p15 (ref.1). The focus of this work is to condense the literature on GATA3 haploinsufficiency correlating to human HDR syndrome. Due to the lack of global healthcare access, it can be assumed that many cases remain undiagnosed; 180 have …

An assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-seq) has become an increasingly popular method to assess genome-wide chromatin accessibility in isolated nuclei from fresh tissues. However, many biobanks contain only snap-frozen tissue samples. While ATAC-seq has been applied to frozen brain tissues in human, its applicability in a wide variety of tissues in horse remains unclear. The Functional Annotation of Animal Genome (FAANG) project is an international collaboration aimed to provide high quality functional annotation of animal genomes. The equine FAANG initiative has generated a biobank of over 80 tissues from two reference female animals and experiments to begin …
Spatial And Temporal Variation Of Epigaeic Beetle Assemblages (Coleoptera, Carabidae, Staphylinidae) In Aspen-Dominated Mixedwood Forests Across North-Central Alberta, H. E. James Hammond, Sergio García-Tejero, Greg R. Pohl, David W. Langor, John R. Spence
Spatial And Temporal Variation Of Epigaeic Beetle Assemblages (Coleoptera, Carabidae, Staphylinidae) In Aspen-Dominated Mixedwood Forests Across North-Central Alberta, H. E. James Hammond, Sergio García-Tejero, Greg R. Pohl, David W. Langor, John R. Spence
Aspen Bibliography
Epigaeic beetle assemblages were surveyed using continuous pitfall trapping during the summers of 1992 and 1993 in six widely geographically distributed locations in Alberta’s aspen-mixedwood forests prior to initial forest harvest. Species composition and turnover (β-diversity) were evaluated on several spatial scales ranging from Natural Regions (distance between samples 120–420 km) to pitfall traps (40–60 m). A total of 19,885 ground beetles (Carabidae) representing 40 species and 12,669 rove beetles (non-Aleocharinae Staphylinidae) representing 78 species was collected. Beetle catch, species richness, and diversity differed significantly among the six locations, as did the identity of dominant species. Beetle species composition differed …

A Screen For Sleep And Starvation Resistance Identifies A Wake-Promoting Role For The Auxiliary Channel Unc79, Kazuma Murakami, Justin Palermo, Bethany A. Stanhope, Allen G. Gibbs, Alex C. Keene
Life Sciences Faculty Research
The regulation of sleep and metabolism are highly interconnected, and dysregulation of sleep is linked to metabolic diseases that include obesity, diabetes, and heart disease. Furthermore, both acute and long-term changes in diet potently impact sleep duration and quality. To identify novel factors that modulate interactions between sleep and metabolic state, we performed a genetic screen for their roles in regulating sleep duration, starvation resistance, and starvation-dependent modulation of sleep. This screen identified a number of genes with potential roles in regulating sleep, metabolism, or both processes. One such gene encodes the auxiliary ion channel UNC79, which was implicated in …

Genetic mutations are alterations in DNA that may result in the development of a disease later in life. A BRCA gene is a tumour suppressor gene that helps to prevent the development of some cancers, particularly breast cancer. If a mutation occurs, this gene no longer functions at preventing these cancers. Genetic screening is when a population is tested for a mutation in an attempt to identify a group of people that are positive for the mutation. This can help identify cancer in different populations as well as track their inheritance. This study was conducted online, questioning the Irish populations …

Synphilin-1 And Its Effects On Pathogenesis Of Parkinson’S Disease, Mirghani Mohamed
Honors Scholar Theses
Parkinson's Disease (PD) is a progressive neurodegenerative and movement disorder primarily caused by the degradation of dopaminergic neurons. Known markers of neurodegeneration in PD are Lewy Bodies, which are fibrillar aggregates that are found in the brains of PD patients. Lewy Bodies can accumulate from specific mutations in the SNCA gene that codes for alpha-synuclein, a protein enriched in presynaptic neurons. A mutated SNCA gene can cause conformational aggregates of alpha-synuclein to form toxic species mediating neuronal death. Research into alpha-synuclein has led to the discovery of a binding partner known as synphilin-1 that is also found in protein aggregates …

Levels of sex differences for human body size and shape phenotypes are hypothesized to have adaptively reduced following the agricultural transition as part of an evolutionary response to relatively more equal divisions of labor and new technology adoption. In this study, we tested this hypothesis by studying genetic variants associated with five sexually differentiated human phenotypes: height, body mass, hip circumference, body fat percentage, and waist circumference. We first analyzed genome-wide association (GWAS) results for UK Biobank individuals (~194,000 females and ~167,000 males) to identify a total of 114,199 single nucleotide polymorphisms (SNPs) significantly associated with at least one of …

Temperature Regulation Of Plant Hormone Signaling During Stress And Development, Christian Castroverde, Damaris Dina
Biology Faculty Publications
Global climate change has broad-ranging impacts on the natural environment and human civilization. Increasing average temperatures along with more frequent heat waves collectively have negative effects on cultivated crops in agricultural sectors and wild species in natural ecosystems. These aberrantly hot temperatures, together with cold stress, represent major abiotic stresses to plants. Molecular and physiological responses to high and low temperatures are intricately linked to the regulation of important plant hormones. In this review, we shall highlight our current understanding of how changing temperatures regulate plant hormone pathways during immunity, stress responses and development. This article will present an overview …

Investigation Of Rack1 Effect On Mor Expression Using Crispr Technology, Zil Modi
Seton Hall University Dissertations and Theses (ETDs)
The µ-opioid receptor, MOR, is the primary target for exogenous and endogenous analgesics, such as morphine or oxycodone, used to relieve pain following physical trauma or invasive procedures. When opioid analgesics are utilized extensively, patients can develop tolerance heightening the risk of respiratory depression and subsequently death. MOR gene expression is known to be regulated by several transcription factors including poly-C binding protein 1, PCBP1, which also interacts with receptor for activated C kinase, RACK1. Using overexpression and siRNA RACK1 was shown to be inversely related to MOR expression. To further investigate the relationship of RACK1 and MOR expression, RACK1 …

Microbial-Host Dynamics And The Evolution Of Nearshore Diversity In Hippocampus Abdominalis, Jimiane L. Ashe
Dissertations, Theses, and Capstone Projects
Local adaptation is a fundamental concept at the core of evolutionary process. Devising means to break down larger concepts and systematically test internal mechanisms are key to understanding the driving forces behind the influence of environmental differences on biological systems. To understand dynamic processes in the natural world, we must strip away layers and confounding variables that may mask the signal we hope to understand. In this case seahorse species, Hippocampus abdominalis, or the pot-bellied seahorse, made an unlikely but ideal study system. The first layer to strip away was neutral genetic variation within the population. A multilocus genetic …

A long history of isolation coupled with complex topographic and ecological landscapes makes Madagascar ideal for exploring the historical factors that have shaped patterns of population diversity and endemism. Many species-level studies have suggested Late Quaternary climate change may have influenced population dynamics in the tropics, but Madagascar’s ecologically unique biomes or individual species properties may have driven idiosyncratic responses to these shifts. Using community-scale population genetic data I implement a hierarchical approximate Bayesian computation (hABC) approach to evaluate the degree of synchronous population expansion during glacial cycles across herpetofaunal assemblages both within and across discrete biomes and taxonomic groups. …
