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 ... -
Addressing Prey Selection And Predator Fitness: Ingestion By, And Growth Of Ochromonas danica On Multiple Bacterial Prey
(Biology, 2012-04-11)Nanoflagellates provide an important link in aquatic food webs by consuming bacterial biomass and subsequently providing nutrients to higher trophic levels by becoming prey themselves and regenerating nutrients consumed ... -
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 ... -
Anti-viral Activity Of Quillaja saponaria Molina Extracts Against HIV-1 And HIV-2
(Biology, 2007-08-23)It has been well established that extracts from the bark of the South American tree Quillaja saponaria Molina have the capacity to stimulate strong immune responses against exogenous antigen when used as an adjuvant. ... -
Anti-viral Capacity Of Quillaja Saponaria Molina Extract Against Vaccinia And Herpes simplex Virus-1
(Biology, 2007-08-23)It is well known that Quillaja saponins have the ability to elicit a strong immune response when used as an adjuvant in an ISCOM matrix. However, to date, the antiviral capability of Quillaja saponins has not been documented. ... -
Arctic Arthropod Communities In Habitats Of Differing Shrub Abundance
(Biology, 2012-07-25)Recent global warming, which has been severe in the Arctic, has caused advancement in the timing of snowmelt and expansion of shrubs into open tundra. Such an altered climate may directly and indirectly (via effects on ... -
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 ... -
A Biochemical Approach To Determine The Target Site Recognition Mechanism Of The R2 Retrotransposable Elements
(Biology, 2011-07-14)Non-LTR Retrotransposons (NLRs) are selfish mobile genetic elements which parasitize the genomes of many organisms including humans. These elements transpose through an RNA intermediate and integrate directly into their ... -
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 ... -
