Phylogeny And Evolutionary Genomics Of Non-Photosynthetic Diatoms, Anastasiia Onyshchenko

Graduate Theses and Dissertations

Diatoms are prolific photosynthesizers responsible for some 20% of global primary production. In real terms, the oxygen in one of every five breaths traces back to photosynthesis by marine diatoms. Among the tens of thousands of diatom species, a small handful of colorless diatom species in the genus Nitzschia have lost photosynthesis altogether and rely exclusively on extracellular organic carbon for growth. I used DNA sequence data to reconstruct the phylogeny of this group, and found that nonphotosynthetic diatoms are monophyletic, indicating that photosynthesis was lost just one time over the course of some 200 million years of diatom evolution. …

Involvement Of The Ino80 Complex In Chromosome Segregation, Jesus Moreno

Graduate Theses and Dissertations

Chromatin remodeling complexes are multi-protein complexes that regulate the dynamics of the nucleosomes in the genome. The INO80 chromatin remodeling complex participates in varied biological processes such as: transcription, DNA repair, DNA replication and chromosome integrity. It catalyzes the eviction of the H2A.Z variant histone as well as whole nucleosome eviction. This complex is comprised of 15 subunits and the contribution of each to chromosome segregations remains unknown. To evaluate the contribution of each subunit to chromosome segregation, we tested deletion mutants of the non-essential subunits for DNA content and benomyl sensitivity. Also, we assessed members of the SWR1 and …

Regulation Of The Tubulin Homolog Ftsz In Escherichia Coli, Monika S. Buczek

Dissertations, Theses, and Capstone Projects

Escherichia coli is a well-known pathogen, and importantly, a widely used model organism in all fields of biological sciences for cloning, protein purification, and as a model for Gram-negative bacterial species. And yet, researchers do not fully understand how this bacterium replicates and divides. Every year additional division proteins are discovered, which adds complexity to how we understand E. coli undergoes cell division. Due to their specific roles in cytokinesis, some of these proteins may be potential targets for development of antibacterials or bacteriostatics, which are much needed for fighting the current global antibacterial deficit. My thesis work focuses on …

Using Molecular Markers To Trace The Population History Of Volant Organisms At Differing Temporal Scales, Noah A. Burg

Dissertations, Theses, and Capstone Projects

Using molecular markers to test phylogenetic and phylogeographic hypotheses is critical for tracking the population origin of invasive, introduced species (Chapter 2, Chapter 4) and to identify the systematic relationships of disparate lineages at both shallow and deep evolutionary time scales (Chapters 3, Chapter 4). In this thesis, Sanger Sequencing was used to generate datasets based on fresh and preserved tissue from specimens collected in the field, as well as museum tissue vouchers granted from various institutions in the US and Europe. In combining these source materials, data were generated for three focal studies: 1) In the first research section …

Development Of Endogenous Tagging Plasmids For Characterization Of Protein Interactions, Localization, And Post-Translational Modifications Of Tetrahymena Thermophila Rad23, Evan Andrew Wilson

Graduate Theses/Dissertations

Rad23 is a protein involved in both nucleotide excision repair (NER) and proteasome-mediated degradation, and has been suggested to facilitate interactions between these two pathways. The model organism Tetrahymena thermophila, which has a transcriptionally silent micronucleus, provides a useful platform for studying the role of Rad23 in global genome NER (GG-NER). However, the ectopic expression systems used thus far in T. thermophila to study Rad23 are repressed by UV light and do not account for the background expression of endogenous RAD23; these phenomena prevent insightful gains to the true dynamics of Rad23. In this thesis, endogenous tagging …

Functional And Structural Impact Of The Loss Of The Leucine-Rich Repeat Protein Lrit1 In The Mouse Retina., Catherine Ann Cobb

Electronic Theses and Dissertations

Mutations in genes encoding the leucine-rich repeat (LRR) proteins nyctalopin and LRIT3 lead to complete congenital stationary night blindness because they are critical to depolarizing bipolar cell function in the retina. LRIT3 has two closely related family members, LRIT1 and LRIT2. In silico analyses of publicly available RNA-Seq data showed that Lrit1 was highly expressed in the retina. Here I describe the expression pattern and impact of loss of LRIT1 on retinal function. To enable these studies, we used CRISPR/Cas9 technology to create an Lrit1^-/- mouse line. Retinal morphology and morphometry analyses showed no gross changes in retinal structure …

Genotype-Specific Insertion Of Cytotoxic Genetic Elements Into Cancer Cells, Ryan Englander

University Scholar Projects

The new gene editing system CRISPR/Cas9, composed of a complex composed of a guide RNA and the Cas9 endonuclease, promises to revolutionize biological research and potentially allow clinicians to directly modify patient DNA in vivo. While its applications in the treatment of genetic diseases and in modifying immune cells for immunotherapy are currently being explored, CRISPR/Cas9’s potential utility as a modular system for targeting tumor-specific mutated sequences has not as of yet been explored. While CRISPR/Cas9 is specific enough to target small insertions and deletions or gross chromosomal rearrangements, it is not specific enough to reliably restrict editing to …

Effect Of Mutation Of Cvn7 Conservon Genes Sco6796 And Sco6798 Of Streptomyces Coelicolor., Caroline Fulmer

Undergraduate Distinction Papers

Abstract

Streptomyces coelicolor is a gram-positive Actinobacterium. It is a filamentous soil organism that performs complex multicellular development. Its physiological and morphological differentiation produces active secondary metabolite antibiotics that have pharmaceutical applications. Studies of S. coelicolor show that cyclic di-GMP proteins regulate physiological and morphological development. S. coelicolor has 13 copies of an operon that are collectively named “conservon” because they are highly conserved. The operons are named cvn1-13 and genes in each operon are denoted cvnA-D. RNA-Seq data of a cyclic di-GMP phosphodiesterase double mutant showed differential expression between wild type and many of the operons in the …

Identifying Rmda Protein Interactions In Streptomyces Using A Bacterial Two-Hybrid System, Rachel Nguyen

Undergraduate Distinction Papers

Streptomyces is a genus of the phylum actinobacteria most commonly found as soil bacteria and used as a major source of antibiotics. RmdA and RmdB are phosphodiesterases that break down the ubiquitous second messenger cyclic-di-GMP which determines colony morphology and development of Streptomyces. The objective of this research is to identify whether RmdA will have interactions with itself using the Bacterial Adenylate Cyclase Two-Hybrid (BACTH) System. Each gene was fused into one of two BACTH vectors that encode a different domain of a single protein (T18 and T25) and then cotransformed into the BACTH indicator strain. The transformants were …

The Identification And Characterization Of A Putative Chromosome Segregation Gene In Streptomyces Coelicolor, Sean Kirk

Undergraduate Distinction Papers

Streptomyces coelicolor is a soil bacterium that is a model for bacterial development. It is a filamentous, sporulating bacterium known to produce many medically utilized antibiotics. The goal of this research was to examine several developmental mutants and characterize novel genes of interest. Previously generated random transposon insertion mutants were analyzed using visual and microscopic phenotyping. Mutants of interest were further pursued and each transposon disruption site was identified by Inverse PCR and DNA sequencing. One of the novel genes is suspected to be involved in DNA segregation and codes for a putative membrane protein. Staining with propidium iodide was …

Efficient Reduced Bias Genetic Algorithm For Generic Community Detection Objectives, Aditya Karnam Gururaj Rao

Theses

The problem of community structure identification has been an extensively investigated area for biology, physics, social sciences, and computer science in recent years for studying the properties of networks representing complex relationships. Most traditional methods, such as K-means and hierarchical clustering, are based on the assumption that communities have spherical configurations. Lately, Genetic Algorithms (GA) are being utilized for efficient community detection without imposing sphericity. GAs are machine learning methods which mimic natural selection and scale with the complexity of the network. However, traditional GA approaches employ a representation method that dramatically increases the solution space to be searched by …

Characterizing The Role Of Cp1 In Drosophila Melanogaster: Its Effects On Basement Membrane Degradation And Signaling, Dane Alan Flinchum

Masters Theses & Specialist Projects

CP1 is a well-conserved cathepsin L-like protease essential for proper growth and development in Drosophila melanogaster. Previous research has demonstrated that CP1 has the ability to break down the extracellular matrix. Using the UAS-GAL4 system, immunohistochemistry, and antibody-staining, this research attempts to characterize the role of CP1 and its effects on basement membrane degradation and signaling. These effects include actions at the cellular level and on a known signaling pathway. The genes involved in this pathway are known to be required for proper development of the wing disc into the adult wing. We have demonstrated the collagenase activity of CP1 …

Neutrophils From Both Susceptible And Resistant Mice Efficiently Kill Opsonized Listeria Monocytogenes, Michelle G. Pitts, Travis A. Combs, Sarah E. F. D'Orazio

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Inbred mouse strains differ in their susceptibility to infection with the facultative intracellular bacterium Listeria monocytogenes, largely due to delayed or deficient innate immune responses. Previous antibody depletion studies suggested that neutrophils (polymorphonuclear leukocytes [PMN]) were particularly important for clearance in the liver, but the ability of PMN from susceptible and resistant mice to directly kill L. monocytogenes has not been examined. In this study, we showed that PMN infiltrated the livers of BALB/c/By/J (BALB/c) and C57BL/6 (B6) mice in similar numbers and that both cell types readily migrated toward leukotriene B4 in an in vitro chemotaxis assay. However, …

Characterization Of A Morphogenetic Furrow Specific Gal4 Driver In The Developing Drosophila Eye, Ankita Sarkar, Neha Gogia, Kevin Farley, Lydia C. Payton, Amit Singh

Biology Faculty Publications

The ability to express a gene of interest in a spatio-temporal manner using Gal4-UAS system has allowed the use of Drosophila model to study various biological phenomenon. During Drosophila eye development, a synchronous wave of differentiation called Morphogenetic furrow (MF) initiates at the posterior margin resulting in differentiation of retinal neurons. This synchronous differentiation is also observed in the differentiating retina of vertebrates. Since MF is highly dynamic, it can serve as an excellent model to study patterning and differentiation. However, there are not any Gal4 drivers available to observe the gain- of- function or loss- of- function of a …

Copy Number Variation In The Porcine Genome Detected From Whole-Genome Sequence, Rebecca Anderson

Honors Program: Senior Projects (Public)

Copy number variations (CNVs) are large insertions, deletions, and duplications in the genome that vary between individuals in a species. These variations are known to impact a broad range of phenotypes from molecular-level traits to higher-order clinical phenotypes. CNVs have been linked to complex traits in humans such as autism, attention deficit hyperactivity disorder, nervous system disorders, and early-onset extreme obesity. In this study, whole-genome sequence was obtained from 72 founders of an intensely phenotyped experimental swine herd at the U.S. Meat Animal Research Center (USMARC) in Clay Center, Nebraska. This included 24 boars (12 Duroc and 12 Landrace) and …

A Comparison Of Oral And Intravenous Mouse Models Of Listeriosis, Michelle G. Pitts, Sarah E. F. D'Orazio

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Listeria monocytogenes is one of several enteric microbes that is acquired orally, invades the gastric mucosa, and then disseminates to peripheral tissues to cause systemic disease in humans. Intravenous (i.v.) inoculation of mice with L. monocytogenes has been the most widely-used small animal model of listeriosis over the past few decades. The infection is highly reproducible and has been invaluable in deciphering mechanisms of adaptive immunity in vivo, particularly CD8+ T cell responses to intracellular pathogens. However, the i.v. model completely bypasses the gut phase of the infection. Recent advances in generating both humanized mice and murinized bacteria, as well …

Advancing Behavioural Genomics By Considering Timescale, Clare C. Rittschof, Kimberly A. Hughes

Entomology Faculty Publications

Animal behavioural traits often covary with gene expression, pointing towards a genomic constraint on organismal responses to environmental cues. This pattern highlights a gap in our understanding of the time course of environmentally responsive gene expression, and moreover, how these dynamics are regulated. Advances in behavioural genomics explore how gene expression dynamics are correlated with behavioural traits that range from stable to highly labile. We consider the idea that certain genomic regulatory mechanisms may predict the timescale of an environmental effect on behaviour. This temporally minded approach could inform both organismal and evolutionary questions ranging from the remediation of early …

New Classification Of The Dictyostelids, Sanea Sheikh, Mats Thulin, James C. Cavender, Ricardo Escalante, Shin-Ichi Kawakami, Carlos Lado, John C. Landolt, Vidyanand Nanjundiah, David C. Queller, Joan E. Strassmann, Frederick W. Spiegel, Steven L. Stephenson, Eduardo M. Vadell, Sandra L. Baldauf

Biology Faculty Research

Traditional morphology-based taxonomy of dictyostelids is rejected by molecular phylogeny. A new classification is presented based on monophyletic entities with consistent and strong molecular phylogenetic support and that are, as far as possible, morphologically recognizable. All newly named clades are diagnosed with small subunit ribosomal RNA (18S rRNA) sequence signatures plus morphological synapomorphies where possible. The two major molecular clades are given the rank of order, as Acytosteliales ord. nov. and Dictyosteliales. The two major clades within each of these orders are recognized and given the rank of family as, respectively, Acytosteliaceae and Cavenderiaceae fam. nov. in Acytosteliales, and Dictyosteliaceae …

Entomology Faculty Publications

The Colorado potato beetle is one of the most challenging agricultural pests to manage. It has shown a spectacular ability to adapt to a variety of solanaceaeous plants and variable climates during its global invasion, and, notably, to rapidly evolve insecticide resistance. To examine evidence of rapid evolutionary change, and to understand the genetic basis of herbivory and insecticide resistance, we tested for structural and functional genomic changes relative to other arthropod species using genome sequencing, transcriptomics, and community annotation. Two factors that might facilitate rapid evolutionary change include transposable elements, which comprise at least 17% of the genome and …

A New Toolset For Protein Expression And Subcellular Localization Studies In Citrus And Its Application To Citrus Tristeza Virus Proteins, Amit Levy, Choaa El-Mochtar, Chunxia Wang, Michael M. Goodin, Vladimir Orbovic

Plant Pathology Faculty Publications

Background

Transient gene expression is a powerful tool to study gene function in plants. In citrus, Agrobacterium transformation is the method of choice for transient expression studies, but this method does not work efficiently with many gene constructs, and there is a need for a more robust transient expression system in citrus leaves. Biolistic particle delivery is an alternative to Agrobacterium transformation, and in some plants, such as Arabidopsis, gives higher transformation rates in leaf tissues than Agrobacterium.

Results

Here we describe an improved method for gene expression in epidermal cells of citrus leaves, using the Bio-Rad Helios gene-gun. …
