Cloning and Characterization of the Classical Maize Mutant, Polytypic1
(East Carolina University, 2019-07-15)Polytypic1 (Pt1) is a semi-dominant mutant in maize that affects inflorescence development. To understand how Pt1 functions in development, I examined the phenotype of Pt1 mutants in multiple inbred backgrounds. Pt1 defects ... -
Cloning, expression, and characterization of a membrane progestin receptor and evidence it is an intermediary in meiotic maturation of fish oocytes
(East Carolina University, 2003-03-04)The structures of membrane receptors mediating rapid, nongenomic actions of steroids have not been identified. We describe the cloning of a cDNA from spotted seatrout ovaries encoding a protein that satisfies the following ... -
Co-teaching Biology 1100 with Dr. Jason Gee
(2014)For my Senior Honors Project, I participated in co-teaching an Introductory Biology, or Biology 1100, class alongside department faculty member Dr. Jason Gee. My overall goals for this project were to better master the ... -
Coevolutionary analysis of Appalachian Xystodesmid millipedes and their symbiotic Mesostigmatid mites
(East Carolina University, 2010)Mites (Acari) form symbiotic relationships with many animal taxa including fish, amphibians, reptiles, birds, mammals, mollusks, and arthropods. They are frequently found living on millipedes, and it has often been ... -
Comparative genomics of cyclin-dependent kinases suggest co-evolution of the RNAP II C-terminal domain and CTD-directed CDKs
(East Carolina University, 2004-09-20)Background: Cyclin-dependent kinases (CDKs) are a large family of proteins that function in a variety of key regulatory pathways in eukaryotic cells, including control over the cell cycle and gene transcription. Among the ... -
Comparison of a Traditional Teaching Model to the SCALE-UP Teaching Model in Undergraduate Biology: A Mixed Method Study
(East Carolina University, 1/13/16)This project compared a SCALE-UP teaching model to a traditional teaching model. Traditional teaching is now considered a poor motivator for student performance and interests, and the SCALE-UP model was proposed to combat ... -
Comparison of the exoS Gene and Protein Expression in Soil and Clinical Isolates of Pseudomonas aeruginosa
(East Carolina University, 2001-04)Exoenzyme S (ExoS) is translocated into eukaryotic cells by the type III secretory process and has been hypothesized to function in conjunction with other virulence factors in the pathogenesis of Pseudomonas aeruginosa. ... -
Comparison of ZnO nanoparticles and ZnCl₂ induced germ cell apoptosis in Caenorhabditis elegans
(East Carolina University, 2014)There is inadequate research data available on manufactured ZnO nanoparticles. Manufactured nanoparticles are widely used in various products and production of manufactured nanoparticles is becoming increasingly abundant. ... -
Components of Reproductive Isolation between Subspecies of an Annual Plant
(2014)Reproductive isolation is required in the divergence of species. The components of reproductive isolation are separated into either ecological or genetic components. In plants these include: habitat, temporal, pollinator ... -
Comprehensive analysis of TCP transcription factors and their expression during cotton () fiber early development
(2016-02)TCP proteins are plant-specific transcription factors implicated to perform a variety of physiological functions during plant growth and development. In the current study, we performed for the first time the comprehensive ... -
A Comprehensive Approach to Identify Reliable Reference Gene Candidates to Investigate the Link between Alcoholism and Endocrinology in Sprague-Dawley Rats
(2014)Gender and hormonal differences are often correlated with alcohol dependence and related complications like addiction and breast cancer. Estrogen (E2) is an important sex hormone because it serves as a key protein involved ... -
Concerted gene recruitment in early plant evolution
(East Carolina University, 2008-07)Background: Horizontal gene transfer occurs frequently in prokaryotes and unicellular eukaryotes. Anciently acquired genes, if retained among descendants, might significantly affect the long-term evolution of the recipient ... -
Connecting Mutations of the RNA Polymerase II C-Terminal Domain to Complex Phenotypic Changes Using Combined Gene Expression and Network Analyses
(2010)The C-terminal domain (CTD) of the largest subunit in DNA-dependent RNA polymerase II (RNAP II) is essential for mRNA synthesis and processing, through coordination of an astounding array of protein-protein interactions. ... -
Consequences Of Long-Term Fertilization on Wetland Microbial Function
(East Carolina University, 2019-05-02)Anthropogenic disturbances have led to increased deposition of nitrogen (N) and phosphorus (P) into soils. Nutrient enrichment of soils is known to increase plant biomass and also increase rates of microbial litter ... -
Consequences of Reduced Versican Expression in Embryonic Chick Synovial Joint Development
(East Carolina University, 2012)The different mechanisms involved in vertebrate synovial joint development are actively being uncovered. A variety of studies have thus far discovered the involvement of several large molecules in the processes of joint ... -
CONSEQUENCES OF SALINIZATION ON CARBON AND NUTRIENT RELEASE FROM A RESTORED COASTAL FORESTED WETLAND
(East Carolina University, 2016-05-04)Given that wetlands provide important ecosystem services, such as improving water quality and protecting inland regions from storms, it is necessary to understand how sea level rise and climate change will alter their ... -
Conservation and Expression of SNF2 Proteins in Chondrus crispus
(2014)The SNF2 families of ATP-dependent helicases are the central catalytic subunits for chromatin remodeling complexes. The most widely studied is the multisubunit SWI/SNF complex, which has been found in plants, yeast, and ... -
Conspecific brood parasitism in the tropics: an experimental investigation of host responses in common moorhens and American purple gallinules
(2011-11)Species occupying a broad latitudinal range may show greater phenotypic plasticity in behavior than species with smaller ranges or more specific habitat requirements. This study investigates for the first time the occurrence ... -
Conspecific pollen precedence and its contribution to speciation in Triodanis perfoliata
(2015)Speciation is the process by which one species diverges into two distinct species. To fully understand speciation, it is important to understand reproductive isolation. Reproductive isolation, the inability of two individuals ... -
Conspicuous female ornamentation and male mate preference of Threespine Sticklebacks (Gasterosteus aculeatus)
(East Carolina University, 2012)Sexual selection drives the evolution of exaggerated male ornaments (traits showing little function outside social interactions) in many animal species. Female ornamentation is now acknowledged also to be common but is ...
