Determining the Chemical Structure of Brucebactin: The Sole Complex Siderophore Utilized by the Pathogenic Bacterium Brucella Abortus
(East Carolina University, 1/13/16)Brucellosis is a zoonotic bacterial disease that affects many around the world. There are over half a million new cases each year and prevalence rates in some areas of the world exceed 10 new cases per 100,000 in the ... -
Determining the Relationship Between Water Quality and Ulcerative Mycosis in Atlantic Menhaden
(East Carolina University, 1993-03)The objectives of this study were to investigate the possible causes of ulcerative mycosis (UM) in the Albemarle-Pamlico Estuary. Ulcerative mycosis is the commonest disease affecting the finfish populations of the ... -
Determining the role of the steroid hormone ecdysone in critical stages of Drosophila melanogaster early oogenesis
(East Carolina University, 2019-11-27)Reproductive function in many organisms, including Drosophila melanogaster, is controlled by steroid hormones. The main steroid hormone in Drosophila is ecdysone, which is structurally and functionally similar to estrogen. ... -
Developing a Panel of Microsatellite Markers for Common Moorhen (Gallinula chloropus) as a Research Tool for Population Studies
(East Carolina University, 2013)The common moorhen (Gallinula chloropus) sometimes exhibits brood parasitism - a parent manipulating a conspecific host to raise its offspring, relieving the parent of the encumbrance of parental investment. It has been ... -
Development of a RAD-Seq Based DNA Polymorphism Identification Software, AgroMarker Finder, and Its Application in Rice Marker-Assisted Breeding
(2016-01)Abstract Rapid and accurate genome-wide marker detection is essential to the marker-assisted breeding and functional genomics studies. In this work, we developed an integrated software, AgroMarker Finder (AMF: ... -
Development of an Optogenetic Tool for Targeted Sensory Hair Cell Ablation in Zebrafish
(East Carolina University, 2022-04-28)Mechanosensory hair cells convert mechanical information into neuronal signals. Mutations in the genes required for hair cell function cause deafness and lead to the degeneration of sensory hair cells. Mammals are unable ... -
Development of Computational Tools and Resources for Cotton microRNA Analysis
(East Carolina University, 2014)MicroRNAs (miRNAs) are an extensive class of small regulatory RNAs which regulate gene expression at the posttranscriptional levels. miRNAs target genes for mRNA cleavage or translation inhibition based on the complementary ... -
Development of Fed and Starved Striped Bass (Morone saxatilis) Larvae from the Roanoke River, North Carolina
(East Carolina University, 1986-07)Fed and unfed striped bass larvae were reared in a laboratory using ambient Roanoke River water to determine differences in growth and development. These differences were used to histologically determine the nutritional ... -
Developmental Patterns of Cleistogamy and Chasmogamy in Triodanis perfoliata
(2015-05)Some plants exhibit mixed mating, in which individual plants utilize both cross and self-fertilization. Dimorphic cleistogamy is one form of mixed mating. In plants that display dimorphic cleistogamy, both chasmogamous ... -
The dicer-like1 Homolog fuzzy tassel Is Required for the Regulation of Meristem Determinacy in the Inflorescence and Vegetative Growth in Maize
(2014-12)Plant architecture is determined by meristems that initiate leaves during vegetative development and flowers during reproductive development. Maize (Zea mays) inflorescences are patterned by a series of branching events, ... -
Did an ancient chlamydial endosymbiosis facilitate the establishment of primary plastids?
(East Carolina University, 2007-06)Background: Ancient endosymbioses are responsible for the origins of mitochondria and plastids, and they contribute to the divergence of several major eukaryotic groups. Although chlamydiae, a group of obligate intracellular ... -
Differential gene expression and alternative splicing in insect immune specificity
(2014-11)Background Ecological studies routinely show genotype-genotype interactions between insects and their parasites. The mechanisms behind these interactions are not clearly understood. Using the bumblebee Bombus terrestris ...
