Editing Fusarium Graminearum Genome With Crispr/Cas9 [Poster], Grace Marie Sack, Tilahun Abebe
Editing Fusarium Graminearum Genome With Crispr/Cas9 [Poster], Grace Marie Sack, Tilahun Abebe
Summer Undergraduate Research Program (SURP) Symposium
Fusarium graminearum is a pathogenic fungus that causes scab or Fusarium head blight disease in barley and wheat. The disease not only reduces yield, but it also contaminates the kernel with harmful toxins. Therefore, the disease causes economic loss and poses a health risk to humans and animals (McMullen et al., 2012). There is no natural resistance to scab disease in barley and there are no effective fungicides to control it. Alternative approaches to protect barley from this devastating disease are badly needed. In recent years, an RNA-guided genome-editing system known as clustered regularly interspaced short palindromic repeat and CRISPR-associated …

Computations Of Top-Down Attention By Modulating V1 Dynamics, David Berga, Xavier Otazu
MODVIS Workshop
The human visual system processes information defining what is visually conspicuous (saliency) to our perception, guiding eye movements towards certain objects depending on scene context and its feature characteristics. However, attention has been known to be biased by top-down influences (relevance), which define voluntary eye movements driven by goal-directed behavior and memory. We propose a unified model of the visual cortex able to predict, among other effects, top-down visual attention and saccadic eye movements. First, we simulate activations of early mechanisms of the visual system (RGC/LGN), by processing distinct image chromatic opponencies with Gabor-like filters. Second, we use a cortical …

Loop-Ligation Of Dna Nanoswitch For Sensitivity Increase, Lillie Carnell
Loop-Ligation Of Dna Nanoswitch For Sensitivity Increase, Lillie Carnell
CURCE Annual Undergraduate Conference
DNA nanoswitches are tools to detect nucleic acids such as microRNAs and viral RNAs. The DNA nanoswitch is a linear duplex structure created from single-stranded circular viral M13 DNA using a DNA origami approach. Each nanoswitch can be designed to have explicit detector strands that bind to a specific DNA sequence. In the presence of a particular target sequence, the DNA nanoswitch will undergo a conformational change in which it switches from a linear “off” state to a looped “on” state. The shape of the DNA nanoswitch can then be detected using standard gel electrophoresis, a cheap and simple test. …
Times Of Action And Evolutionary Conservation Of Heterochronic Genes, Maria Ivanova, Eric G. Moss
Times Of Action And Evolutionary Conservation Of Heterochronic Genes, Maria Ivanova, Eric G. Moss
Rowan-Virtua Research Day
Specific genes called heterochronic genes control the timing and sequence of developmental events during larval stages of C. elegans. Mutations in heterochronic genes can cause skipping or reiteration of cell fates associated with certain larval stages. lin-14 and lin-28 are two well-studied heterochronic genes. LIN-14 acts during the first larval stage (L1) and controls events of the L1 and L2 stages, LIN-28 acts during the L2 stage and controls its events.

The Full Genome Sequence Of An Antarctic Microbe Constructed Using A Rapid, Portable Sequencer And A Hybrid Assembly, Bruce Wyatt Boles
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Microbial genomes contain combinations of nucleotides that code for genes which subsequently determines the function of the cell. This information provides significant insight into the unique niche of microbes from extreme environments. Here we use two sequencing technologies, the Oxford Nanopore MinION with accompanying software and Illumina HiSeq, to generate a hybrid genome for a Shewanella strain isolated from an Antarctic glacier. Bioinformatic programs, Albacore and SPAdes, allowed us to decrease the time of genome assembly while also obtaining a large quantity of information related to the Shewanella sp. Our combined approach yielded a high quality genome assembly 5.3 …
Circadian Rhythmicity And Neurodevelopment Of Disco And Grim Mutations In Drosophila Melanogaster, John Patrick Story
Circadian Rhythmicity And Neurodevelopment Of Disco And Grim Mutations In Drosophila Melanogaster, John Patrick Story
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
The death gene grim and its pathway for apoptosis has been studied extensively in Drosophila Melanogaster. The effects of grim mutations on circadian neurodevelopment and locomotor assays have yet to be investigated. Mutations in the gene disconnected (disco) has been shown to disrupt the normal development of the circadian circuitry, specifically the small ventro-lateral neurons (s-LNv’s). Which has shown to severely decrease rhythmicity during free-running periods. Alternatively, we have observed an increase in rhythmicity during free-running periods in grim mutations. Our goal is to investigate the neurodevelopment of the circadian circuitry and their associated locomotor activities in these Drosophila mutations.

Ultramicrobacteria Genome Database Project, Abdullah A. Salim, Tien Tran, Andrew Putt, Terry C. Hazen
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Ultramicrobacteria (UMB) are a largely uncultured, globally abundant, and metabolically active group of bacteria. UMB have cell diameters ≤0.3μm, cell volumes ≤0.1 μm3, and small streamlined genomes. Recent findings indicate that UMB aid in bioremediation and nutrient cycling, but future investigations and comprehension of current findings are skewed by highly variable nomenclature and a lack of databases for functional, genomic, geochemical, or spatial data specific to candidate UMB. We aim to develop a user-friendly open-access database of various UMB candidates linked to an open-access online map where researchers can gather genomic, spatial, and geochemical data. Our comprehensive review of literature …

Co-Occurrence Of Manganese Oxidase Genes Indicates Lateral Transfer Between Classes Of Proteobacteria, Jacob Olichney
Student Scholar Showcase
Pseudomonas putida GB-1 is a model organism for the study of manganese oxidation in bacteria, however, the frequency of co-localization of multiple known and suspected manganese oxidizing proteins, as well as their occurrence between species, is unknown. Eight different genes isolated from known manganese oxidizing bacteria (MnxG, MopA, McoA, PputGB1_2552, PputGB1_2553, MoxA, MofA, and Bacillus MnxG) were tested individually using BioPython and BLAST (Basic Local Alignment Search Tool) on multiple genomic databases. BLAST searches had an expect value cutoff of 1e-50, limiting gene homologs to those with high sequence similarity. The abundance of homologous genes across classes of proteobacteria point …

A Screen For Genetic Modifiers Of Protein Phosphatase 1 Function In Drosophila Collective Cell Cohesion And Migration, Carmen F. Del Real, Yujun Chen, Marissa Komp, Jocelyn A. Mcdonald
Kansas State University Undergraduate Research Conference
Cells can migrate collectively in tightly or loosely-associated groups during tissue and organ formation, during embryonic development, in tumor metastases, and in wound healing. Drosophilaborder cellsserve as an excellent genetic model of collective cell migration inside a developing tissue. During ovarian development, 6-8 cells form the border cell cluster and migrate together as a cohesive group to reach the large oocyte. Previous experiments have shown that Nuclear inhibitor of Protein Serine Threonine Phosphatase 1 (NiPP1) causes border cells to separate into single cells, rather than stay in a group, and limits their ability to migrate. NiPP1 inhibits the …

Meta-Analysis Of Characteristics In Upper Missouri River Fishes: Prediction Of Invasiveness, Steph Purcell
UNO Student Research and Creative Activity Fair
Invasive species are often considered a global threat due to their association with biodiversity loss and novel diseases. The Missouri-Mississippi River Watershed, including the Missouri River Basin, is particularly vulnerable to invasive species because of low species diversity following historic glaciation events. Management of invasive species is imperative in this watershed but continues to be challenging in that there are over 100 invasive species currently present in this region. The goal of this project is to identify characteristics associated with successful invasions that may assist in developing management strategies to reduce the negative outcomes caused by the establishment of invasive …

Investigating Comt Influence On The Proactive-Reactive Stress Coping Axis In Zebrafish, Sean T. Bresnahan, Ryan Y. Wong
UNO Student Research and Creative Activity Fair
Individuals of the same species often display differences in correlated suites of behaviors which are made conspicuous when challenges – stressful, fear-inducing, etc. – are presented. In many species, a specific suite of behaviors (risk-aversion, aggression, exploration, learning, and memory) characterize an alternative set of stress coping styles (proactive and reactive). Such behaviors are regulated in the brain by specific neurotransmitters along with proteins that regulate them. One neurotransmitter regulator protein, catechol-O-methyltransferase (COMT) shows higher baseline whole-brain expression in proactive relative to reactive animals. However, it is not known whether its expression is a cause or a consequence of the …

Non-Invasive Analysis Of The Sputum Transcriptome Discriminates Clinical Phenotypes Of Asthma, Xiting Yan
Yale Day of Data
Whole transcriptome wide gene expression profiles in the sputum and circulation from 100 asthma patients were measured using the Affymetrix HuGene 1.0ST arrays. Unsupervised clustering analysis based on pathways from KEGG were used to identify TEA clusters of patients from the sputum gene expression profiles. The identified TEA clusters have significantly different pre-bronchodilator FEV1, bronchodilator responsiveness, exhaled nitric oxide levels, history of hospitalization for asthma and history of intubation. Evaluation of TEA clusters in children from Asthma BRIDGE cohort confirmed the identified differences in intubation and hospitalization. Furthermore, evaluation of the TH2 gene signatures suggested a much lower prevalence of …
A Novel Pathway-Based Distance Score Enhances Assessment Of Disease Heterogeneity In Gene Expression, Yunqing Liu, Xiting Yan
A Novel Pathway-Based Distance Score Enhances Assessment Of Disease Heterogeneity In Gene Expression, Yunqing Liu, Xiting Yan
Yale Day of Data
Distance-based unsupervised clustering of gene expression data is commonly used to identify heterogeneity in biologic samples. However, high noise levels in gene expression data and the relatively high correlation between genes are often encountered, so traditional distances such as Euclidean distance may not be effective at discriminating the biological differences between samples. In this study, we developed a novel computational method to assess the biological differences based on pathways by assuming that ontologically defined biological pathways in biologically similar samples have similar behavior. Application of this distance score results in more accurate, robust, and biologically meaningful clustering results in both …
