A DROUGHT-TOLERANT NITROGEN-FIXING SYMBIONT FOR SUSTAINABLE SOYBEAN PRODUCTION
(2023-01-02)Bradyrhizobia are an ideal model organism to study plant-microbe interactions due to dual lifestyles as free-living soil organisms and as endosymbionts for valuable cropping systems in agriculture. Farmers have been utilizing ... -
A Study Of The Function Of Two Nuclear Transport Retrogenes (dntf-2r And Ran-like) In Drosophila Melanogaster
(Biology, 2014-12)The genetic information, DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), is the hereditary material that forms the basis for the origin and evolution of life. These molecules encode and store information that can ... -
Analysis Of Novel Regulatory Region And Function Of A Young Drosophila Retrogene: Dntf-2r
(Biology, 2009-09-16)Dntf-2r is a young retroposed gene that originated from the nuclear transport gene Dntf-2. Here the function, quality and evolutionary origin of the regulation of this retrogene are explored. In Chapter 1, I introduce the ... -
Analysis Of The Suppressive Effects By Reovirus On Rotavirus Replication During Co-infections
(Biology, 2010-11-01)Reovirus and rotavirus are both members of the Reoviridae family and commonly occur in children. Rotavirus induced diarrhea is one of the leading causes of death in children under the age of five worldwide. Identifying ... -
An Analysis Of Tracheid Length Versus Age In A 4842-year Old Bristlecone Pine (Pinus longaeva D.K. Bailey) Called Prometheus
(Biology, 2009-09-16)After felling, it was revealed that Prometheus, an ancient bristlecone pine (Pinus longaeva D.K. Bailey) located in the Great Basin National Park, had been the oldest living organism at over 5000 years of age. Great Basin ... -
ARTHROPOD FOOD WEBS IN ARCTIC TUNDRA: TROPHIC INTERACTIONS AND RESPONSES TO GLOBAL CHANGE
(2017-08-09)Arctic ecosystems are undergoing rapid change. Terrestrial arctic arthropods (insects, spiders and others) are not only appreciably diverse, but also sensitive to their environment. As such, tundra arthropod communities ... -
Biodiversity in the Anthropocene, understanding the impacts of land-use change, and species interactions.
(2023-08-10)**Please note that the full text is embargoed until 8/1/2024** ABSTRACT: The extent of human influences on the environment and biodiversity has led to naming our current time period the Anthropocene. A primary way in which ... -
Bioinformatic Identification Of Small RNA (and Their Targets) In The Testis Of Clawed Frogs (Xenopus And Silurana): Implications For Male Fertility
(Biology, 2012-04-11)Chapter one sets the stage for this project, which lies somewhere near the intersection of speciation, genome, and reproductive biology. Chapter two identifies miRNA with shared expression profiles (Silurana and Xenopus). ... -
Biological Evaluation Of Membrane-active Compounds As Treatment For Clostridium Difficile Infection
(Biology, 2015)Clostridium difficile infection (CDI), which is caused by a spore-forming, gram-positive anaerobe, named C. difficile, is the leading cause of the hospital-acquired antibiotic-associated diarrhea. Hospitalized elderly ... -
Biological Relevance Of JAZ Proteins In The Interaction Between Pseudomonas syrinage And Arabiopsis thaliana
Stomata, micro-pores on the leaf surface, are formed by a pair of guard cells. In addition to controlling water loss and gas exchange between the plant and the environment, these cells act as immunity gates to prevent ... -
Cell division in Mycobacteria: the role of SepIVA
(2023-05-11)Today, about a quarter of the world’s population are infected with Mycobacterium tuberculosis (Mtb) and therefore, are at risk of developing tuberculosis (TB) disease. Tuberculosis, on average, takes about six months to ... -
Characterization Of Anti-rotavirus Activities Of Saponin Extracts From Quillaja Saponaria
(Biology, 2010-11-01)Rotavirus is the leading cause of severe diarrhea disease in newborns and young children worldwide, estimated to be responsible for over 500,000 adolescent deaths mostly in developing countries each year. Rotavirus-related ... -
CHEMICAL AND GENETIC ANALYSIS OF THE MITOCHONDRIAL UNFOLDED PROTEIN RESPONSE
(2021-06-29)Mitochondria are essential for energy production, metabolic signaling, calcium homeostasis, and other roles. Consequently, mitochondrial dysfunction can result in cellular decline and the onset of disease. Cells use the ... -
Circadian Orchestration of Symbiotic Genes in Photosynthetic Nitrogen-Fixing Bacteria
(2018-05-04)Rhizobia have long been known for their symbiotic association with the roots of legumes where they perform nitrogen fixation in specialized organs called nodules. The photosynthetic strains of Bradyrhizobia are of particular ... -
Combating Bacterial Infections with In-Situ Detection and Antibiotic Technology
(2020-08-10)Currently, there is a looming crisis in the field of antibacterial drug therapy. The emergence of antibacterial drug resistance because of poor antibacterial stewardship, coupled with booming elderly populations, economic ... -
A Comparative Approach To Elucidating The Physiological Response In Symbiodinium To Changes In Temperature
(Biology, 2014-03-10)Coral reefs are one of the most biodiverse ecosystems, and play a large role in the functioning of oceanic and coastal ecosystems. They are currently declining around the world, largely due to the effects of climate change ... -
