CRF2 and its role in cytokinin response and abiotic stress
(2018-07-24)
Cytokinin Response Factors are a small family of plant transcription factors originally discovered in a screen for genes whose expression is controlled by cytokinin. Cytokinin is a plant hormone known to be involved in ...
Cytokinin Response Factor 4: A Role in Development During Cold Stress in Arabidopsis thaliana
(2012-07-20)
Cold stress is a major cause of crop loss annually in the United States such that a detailed study
of the mechanisms and genes behind these stresses are essential for improvement of crop plants.
This thesis investigated ...
Deep genetic divergence in the Deep South: An integrative approach to species delimitation reveals the paraphyletic nature of speciation in the trapdoor spider genus Cyclocosmia.
(2018-01-09)
Mygalomorph spiders house an incredible amount of cryptic genetic information, making them an excellent model for species delimitation. An integrative approach to species delimitation uses multiple lines of evidence to ...
Demography of the corkscrew sea anemone Bartholomea annulata in the Florida Keys and in laboratory culture: a giant sea anemone under pressure.
(2015-12-11)
The successful management of species requires information on their patterns of distribution, abundance, and population dynamics. Demographic studies are important for gauging how environmental conditions impact populations; ...
Descriptions and Phylogenetic Relationships of the Guiana Shield Pencil Catfishes
(2022-07-21)
The systematics of the catfish genus Trichomycterus Valenciennes 1832 are complicated and unresolved. This genus is paraphyletic, containing all members of the Trichomycterinae that cannot be adequately placed into an ...
Determining the spatial and seasonal influences of microbial community composition and structure from the Hawaiian anchialine ecosystem
(2016-12-09)
Characterized as coastal bodies of water lacking surface connections to the ocean but with subterranean connections to the ocean and groundwater, habitats belonging to the anchialine ecosystem occur worldwide in primarily ...
Developing omics and cell culture resources in non-model organism for their application in elucidating complex trait evolution in natural populations.
(2022-08-15)
In the past, researchers chose models organisms to answer research questions based on their simplicity in morphology, domestication, and/or life history traits. Now, with high throughput sequencing (HTS) rapidly becoming ...
Development of functional capacity and bactericidal activity in myeloid cells during GM-CSF driven differentiation
(2018-07-18)
Dendritic cells (DC) form an interface between the innate and adaptive immune systems. DC respond to infection or inflammatory signals by orchestrating other immune cells to perform protective functions. These include ...
The developmental environment and metabolism in the house mouse (Mus musculus)
(2014-07-09)
The environment under which an individual develops plays an important role in
determining its physiological phenotype. Maternal diet is one of several variables that can have
lasting impacts on offspring phenotype. ...
Dietary mercury and stress responses: how lifetime exposure to mercury alters stress responses and their relationship to spatial cognition
(2019-04-25)
Methylmercury is a widespread environmental contaminant that negatively impacts both humans and wildlife at sublethal levels. While environmental sources of methylmercury exist, the primary sources are anthropogenic, and ...
Differences in the Survival, Transmission, and Susceptibility to Disinfection of M1 and M5 Protein Possessing Streptococcus pyogenes and Other Pathogens on Airplane Cabin Surfaces
(2015-12-10)
Recent reports regarding the transmission of Mycobacterium tuberculosis and other microorganisms in airplane cabins compel us to examine the factors for pathogen transmission in that environment. We tested the survival and ...
Discovery and characterization of antibacterial compounds expressed by soil microorganisms using culture-dependent and -independent approaches
(2015-07-31)
The emergence of multidrug-resistant pathogens has increased the demand for discovery of novel antibiotics. Both culture-dependent and culture-independent approaches were used to discover antibiotics against methicillin-resistant ...
Discovery and Characterization of High-frequency Calls in North American Flying Squirrels (Glaucomys sabrinus and G. volans): Implications for Ecology, Behavior, and Conservation
(2013-02-11)
Studies of bioacoustics of vertebrates primarily have focused on amphibians and birds. Comparatively, the acoustic repertoire of mammals is poorly understood, and even less is known about the production of high-frequency ...
Discovery and Characterization of Novel Antibiotic Synthesis and Resistance Determinants from Diverse Microbial Metagenomes
(2010-07-09)
The application of metagenomics to investigate the genetic and functional diversity of as-yet-uncultured microorganisms from natural environments has been one of the most significant breakthroughs in molecular microbiology. ...
Discovery of the Gene Cluster in Bacillus velezensis AP183 Responsible for Bacillusin A Biosynthesis, Evaluation of the Use of B. velezensis AP183 in Preventing Staphylococcus aureus Infection, and Identification of Bacteriocins From a Soil Metagenome.
(2021-11-29)
The spread of multidrug resistance among pathogenic bacteria is increasing worldwide. One of the multidrug resistance pathogens is methicillin-resistant S. aureus (MRSA) which poses a significant threat to health and causes ...
