Aiding Plants and Humans by Targeting Virulence Strategies: Investigation of key protein residues involved in toxoflavin production

Creator:: Justen, Savannah F.
Abstract:: Toxoflavin, a toxic secondary metabolite produced by a variety of bacteria, has been implicated as a causative agent in food poisoning and a virulence factor in phytopathogenic bacteria. This toxin is produced by the tox operon in Burkholderia glumae, in which the encoded protein, ToxD, was previously characterized as essential...

The role of sigma factors in production of cyanobacterial natural products: Escherichia coli as a heterologous expression host

Creator:: Wells, Kaitlyn N.
Abstract:: Cyanobacteria represent an underexploited source of bioactive natural products of interest to the pharmaceutical industry. Lack of development of these compounds as drug leads is due mainly to myriad practical problems with the producing strains including long doubling times, genetic intractability, and low compound yields. Previous attempts at heterologous expression...

Analysis of SNPs in Mycoplasma cynos strains from canine hosts within the Pacific Coast animal shelter network

Creator:: Prymolenna, Anastasiya V.
Abstract:: Single nucleotide polymorphisms (SNPs) can be used as markers to infer population genetic structure. For Mycoplasma cynos, a pathogen associated with infectious respiratory disease among canines and other animals, SNPs may help to elucidate ecological and evolutionary relationships among the strains that reside in the upper respiratory tract of canines...

Characterizing the Interaction between BCL11B and TCF-1 transcription factors in the control of the BCL-xL gene

Creator:: Nagra, Alamjit K.
Abstract:: Immature T cells, known as thymocytes, undergo development through successive stages in the thymus and the periphery to become functional mature T cells. These stages are regulated by sequence specific transcription factors (SSTFs). Two such SSTFs, BCL11B and TCF-1, are both known master regulators of thymopoiesis, which is also known...

Isolation and Identification of Indole Metabolites from Pseudomonas fluorescens NZI7

Creator:: Vergis, John M.
Abstract:: Pseudomonas fluorescens NZI7 was first isolated from a New Zealand mushroom farm in 2001. This Gram-negative bacteria can cause brown blotch disease in the basidiomycete mushroom Agaricus bisporus. P. fluorescens NZI7 can also repel grazing by the nematode Caenorhabditis elegans, a natural predator of P. fluorescens NZI7. Potentially implicated in...

Stress and Learning in Larval Zebrafish (Danio rerio)

Creator:: Moussaoui, Bushra
Abstract:: In this study, we characterize the behavioral response of larval zebrafish (Danio rerio) to the noxious chemical allyl isothiocyanate (AITC), an agonist of the nociceptive TRPA1 ion channel, and utilize AITC as an aversive stimulus in an associative learning paradigm. We find that larvae exposed to AITC in both a...

Genetic and morphological evidence suggests cryptic speciation within the Torrent Sculpin, Cottus rhotheus, across the Pacific Northwest

Creator:: Nicholas, Benjamin P.
Abstract:: Dwelling on the bottom of large rivers to high alpine streams, freshwater sculpins (genus Cottus) occur in high densities across the Pacific Northwest, with 21 currently recognized species found in the Pacific Northwest. Sculpin fill many ecological roles, with some species serving as important prey sources, and others competing with...

A Graphical Method of Computing Offset Curves

Creator:: Weiss, Benjamin M.
Abstract:: Computation of offset curves is an operation critical to many computer-aided design and manufacturing (CAD/CAM) applications. Though simple on the surface, differences between the straightforward mathematical definition and the demands of CAD/CAM environment in the formulation and expression of an offset curve create a problem for which only complicated, approximate...

Old McDonald had a Microscope: The Impact of Research Spending on U.S. Agricultural Productivity

Creator:: Rietmann, Benjamin J.
Abstract:: The United States is a global leader in agricultural productivity. Much of its productivity growth can be attributed to public investments in agricultural research and development, starting in the 19th century and continuing until today. Past studies have shown high returns to agricultural research investments, but publicly funded agricultural research...

Locating Radio Signals Using Software Defined Radio

Creator:: Johnson, Benjamin E.
Abstract:: Locating sources of radio signals can be useful in many applications. From pointing antennas at nearby radio towers to fox hunting, being able to determine the relative location or direction to a radio transmitter can be very useful. Generally, it is necessary to have the current GPS locations of both...
