The NAM, ATAF1/2, and CUC2 (NAC) transcription factors form a large plant-specific gene family, which is involved in the regulation of tissue development in response to biotic and abiotic stress. To date, there have been no comprehensive studies investigating chromosomal location, gene structure, gene phylogeny, conserved motifs, or gene expression of NAC in pepper (Capsicum annuum L.). The recent release of the complete genome sequence of pepper allowed us to perform a genome-wide investigation of Capsicum annuum L. NAC (CaNAC) proteins. In the present study, a comprehensive analysis of the CaNAC gene family in pepper was performed, …

Abstract
Background: With approximately one-third of their genomes consisting of linear and circular plasmids, the Lyme disease agent cluster of species has the most complex genomes among known bacteria. We report here a comparative analysis of plasmids in eleven Borreliella (also known as Borrelia burgdorferi sensu lato) species.
Results: We sequenced the complete genomes of two B. afzelii, two B. garinii, and individual B. spielmanii, B. bissettiae, B. valaisiana and B. finlandensis isolates. These individual isolates carry between seven and sixteen plasmids, and together harbor 99 plasmids. We report here a comparative analysis of these plasmids, along with 70 additional …
R1 Retrotransposons In Drosophila Melanogaster Are Transcribed By Rna Polymerase I Upon Heat Shock, 2018 Louisiana State University and Agricultural and Mechanical College
R1 Retrotransposons In Drosophila Melanogaster Are Transcribed By Rna Polymerase I Upon Heat Shock, Himanshu Shekhar Raje
LSU Doctoral Dissertations
The ribosomal RNA genes of Drosophila melanogaster reside within centromere-proximal nucleolar organizers on both the X and Y chromosomes. Each locus contains between 200-300 tandem repeat rDNA units that encode 18S, 5.8S, and 28S ribosomal RNAs (rRNAs) for ribosome biogenesis. In arthropods like Drosophila, about 60% of rDNA genes are inserted with R1 and/or R2 retrotransposons at specific sites within the 28S regions; these units likely fail to produce functional 28S rRNA. We showed previously that R2 expression increases upon nucleolar stress caused by the loss of a ribosome assembly factor, the Nucleolar Phosphoprotein of 140 kDa (Nopp140). Here …

Changes In The Proliferation And Gene Expression Of Huvecs In Response To Treatment With Plant Secondary Metabolites, Caleigh Howard
Seaver College Research And Scholarly Achievement Symposium
Medicinal plants have historically been a valuable source of new drugs, and Southern California possesses a rich collection of native plants which have been used as medicines by native people groups for thousands of years. Angiogenesis is the biological process of new blood-vessel growth from endothelial cells. It is an essential part of the wound-healing process, and increased angiogenesis has also been implicated in the growth of some types of cancerous tumors. In this study, extracts of the Southern Californian native plants Red shanks (Adenostoma sparsifolium) and the alkaloid extract of Jimson weed (Datura wrightii) were …

Impacts Of Genome And Nuclear Architecture On Molecular Evolution In Eukaryotes, Xyrus Maurer-Alcalá
Doctoral Dissertations
The traditional view of genomes suggests that they are static entities changing slowly in sequence and structure through time (e.g. evolving over geological time-scales). This outdated view has been challenged as our understanding of the dynamic nature of genomes has increased. Changes in DNA content (i.e. polyploidy) are common to specific life-cycle stages in a variety of eukaryotes, as are changes in genome content itself. These dramatic genomic changes include chromosomal deletions (i.e. paternal chromosome deletion in insects; Goday and Esteban 2001; Ross, et al. 2010), developmentally regulated genome rearrangements (e.g. the V(D)J system in adaptive immunity in mammals; Schatz …
An Analysis Of Alu Elements In Baboons, 2018 Louisiana State University and Agricultural and Mechanical College
An Analysis Of Alu Elements In Baboons, Cody James Steely
LSU Doctoral Dissertations
Transposable elements compose a large portion of mammalian genomes and are estimated to make up anywhere from ~45% - ~70% of the human genome. Alu elements are primate-specific retrotransposons that are found in high copy number (> 1 million copies) and are spread throughout the genome. These elements are the most commonly repeated sequence in the human genome and have contributed to a number of disease states in humans. Alu elements are useful markers for population genetics and phylogenetics and have proven valuable in understanding difficult to determine relationships between species and within populations.
Baboons (genus Papio) are spread throughout …

Spinal muscular atrophy (SMA) is caused by homozygous mutations in human SMN1. Expression of a duplicate gene (SMN2) primarily results in skipping of exon 7 and production of an unstable protein isoform, SMNΔ7. Although SMN2 exon skipping is the principal contributor to SMA severity, mechanisms governing stability of survival motor neuron (SMN) isoforms are poorly understood. We used a Drosophila model system and label-free proteomics to identify the SCFSlmb ubiquitin E3 ligase complex as a novel SMN binding partner. SCFSlmb interacts with a phosphor degron embedded within the human and fruitfly SMN YG-box oligomerization domains. …
A Genetic Screen To Identify Fission Yeast Genes With Roles In Protecting Against Perturbation Of The Actin Cytoskeleton, 2018 The University of Western Ontario
A Genetic Screen To Identify Fission Yeast Genes With Roles In Protecting Against Perturbation Of The Actin Cytoskeleton, Dorota Michalski
Electronic Thesis and Dissertation Repository
In the fission yeast, Schizosaccharomyces pombe, stress upon the cell division machinery leads to the activation of a cytokinesis checkpoint. This checkpoint results in a delay in cell cycle progression and the prolonged maintenance of a cytokinesis competent cellular state. In this state the cell is able to continuously reform/repair the actomyosin ring until cell division is achieved. To uncover genes that play a role in enforcing this checkpoint, the actin depolymerizing drug Latrunculin A (LatA) was used to perturb the cytokinetic machinery in a set of 3400 viable haploid S. pombe gene deletion mutants. Thirty-eight gene deletion mutants hypersensitive …

Despite the devastating impact of the lionfish (Pterois volitans) invasion on NW Atlantic ecosystems, little genetic information about the invasion process is available. We applied Genotyping by Sequencing techniques to identify 1,220 single nucleotide polymorphic sites (SNPs) from 162 lionfish samples collected between 2013 and 2015 from two areas chronologically identified as the first and last invaded areas in US waters: the east coast of Florida and the Gulf of Mexico. We used population genomic analyses, including phylogenetic reconstruction, Bayesian clustering, genetic distances, Discriminant Analyses of Principal Components, and coalescence simulations for detection of outlier SNPs, to understand …

Recent study has shown that RNA interference (RNAi) is efficient in emerald ash borer (EAB), Agrilus planipennis, and that ingestion of double-stranded RNA (dsRNA) targeting specific genes causes gene silencing and mortality in neonates. Here, we report on the identification of highly effective target genes for RNAi-mediated control of EAB. We screened 13 candidate genes in neonate larvae and selected the most effective target genes for further investigation, including their effect on EAB adults and on a non-target organism, Tribolium castaneum. The two most efficient target genes selected, hsp (heat shock 70-kDa protein cognate 3) and shi (shibire), …

Food intake is necessary for survival, and natural reward circuitry has evolved to help ensure that animals ingest sufficient food to maintain development, growth, and survival. Drugs of abuse, including alcohol, co-opt the natural reward circuitry in the brain, and this is a major factor in the reinforcement of drug behaviors leading to addiction. At the junction of these two aspects of reward are alterations in feeding behavior due to alcohol consumption. In particular, developmental alcohol exposure (DAE) results in a collection of physical and neurobehavioral disorders collectively referred to as Fetal Alcohol Spectrum Disorder (FASD). The deleterious effects of …

Killifish Research Review
Valued readers, it is with a heavy heart that I inform you that this is the last issue of Killi-Data News. The good news is that we will be back as Killifish Research Review. The dissolution of Killi-Data International created a prob- lem: how can the newsletter of a defunct organization live on without that organization? But other additional problems were building in the background. The first issue numbered 15 pages. The previous issue was 28 pages. The number of killifish related papers is increasing while time on our end (the editorial team) is running out. It takes a lot …

Many interesting papers have been published over the last three months. The large volume of papers coupled with the start of the new college semester (and the workload it brings) delayed this issue of Killi-Data News. But better late than never—or so I hope! In this issue Richard van der Laan provides an insightful review of the recent Aphanius papers as to their taxonomic implications and questions. The systematic issues he raises show the importance of the Molecular project: we need to get more samples of the various cyprinodontiforme families to resolve unsettled systematic and taxonomic issues. In the Next …

Manipulation Of Ploidy In Caenorhabditis Elegans, Erlyana K. Clarke, Katherine A. Rivera Gomez, Zaki Mustachi, Mikaela C. Murph, Mara Schvarzstein
Advanced Science Research Center
Mechanisms that involve whole genome polyploidy play important roles in development and evolution; also, an abnormal generation of tetraploid cells has been associated with both the progression of cancer and the development of drug resistance. Until now, it has not been feasible to easily manipulate the ploidy of a multicellular animal without generating mostly sterile progeny. Presented here is a simple and rapid protocol for generating tetraploid Caenorhabditis elegans animals from any diploid strain. This method allows the user to create a bias in chromosome segregation during meiosis, ultimately increasing ploidy in C. elegans. This strategy relies on the transient …

Research into gene therapy for heart failure has gained renewed interest as a result of improved safety and availability of adeno-associated viral vectors (AAV). While magnetic resonance imaging (MRI) is standard for functional assessment of gene therapy outcomes, quantitation of gene transfer/expression relies upon tissue biopsy, fluorescence or nuclear imaging. Imaging of gene expression through the use of genetically encoded chemical exchange saturation transfer (CEST)-MRI reporter genes could be combined with clinical cardiac MRI methods to comprehensively probe therapeutic gene expression and subsequent outcomes. The CEST-MRI reporter gene Lysine Rich Protein (LRP) was cloned into an AAV9 vector and either …
