Christopher D. Rice and Dr. William McCleary, Molecular and Microbiology Phosphate is a necessary chemical compound for life at any level. Organisms have developed different means of obtaining phosphate from their environments and maintaining an intracellular phosphate homeostasis. The creation and maintenance of such a homeostasis at the very least requires mechanisms for sensing phosphate […]
Detection of Streptococcus pyogenes on Applied Biosystems, Cepheid, and Rochereal-time PCR Platforms
Eldon Prince and Dr. Richard Robison, Microbiology & Molecular Biology Goal/Purpose Develop a real-time PCR assay to uniquely detect S. pyogenes on all three major real-time PCR platforms. Importance of Project A faster clinical test would enable doctors to more quickly diagnose and treat group A streptococcal infections. The test we developed can be run […]
Discovery and Development of New Tomato Spotted Wilt Virus Resistance Genes
David L. Price and Dr. Mikel R. Stevens, Plant and Wildlife Sciences The tomato is susceptible to more than 200 diseases. Tomato spotted wilt virus is one of the most damaging pathogens in tomatoes. Due to its wide spread, TSWV has become an important limiting factor in tomato production worldwide. Most often the virus is […]
Identification of Genes Related to Saponin Synthesis in Chenopodium Quinoa
Chris Nye and Dr. Jeff Maughan, Plant and Wildlife Sciences Chenopodium quinoa, commonly known as quinoa, is a vital crop to the subsistence farmers of the Altiplano region of South America. Quinoa has several unique characteristics which contribute to its ability to grow in a variety of harsh conditions found in the high altitudes and […]
Phosphorus, Zinc, and Manganese Interactions in Hydroponically Grown Maize
Brandt Nichols and Dr. Von D. Jolley, Plant and Wildlife Maize (Zea maize L.) roots prolifically explore soil and this requires less intensive phosphorus (P) fertilization than less efficient species, such as potato (Solanum tuberosum L.). Crops are not grown in isolation and species requiring high P are often grown in rotation with low P […]
Assessing the Effects of Primer Specificity on Eliminating Numt Co-amplification in DNA Barcoding
Matthew Moulton and Dr. Michael Whiting, Department of Biology Introduction DNA barcoding is a method of species identification based on sequencing a short mitochondrial DNA fragment of Cytochrome Oxidase I (COI). A database of over 500,000 of these COI fragments, known as “barcodes,” has been established for nearly 38,000 species and is currently being used […]
Bromus tectorum: Cheating its Way to the Top
Keith R. Merrill and Dr. Craig E. Coleman, BYU Plant and Wildlife Sciences Introduction Bromus tectorum (cheatgrass, or downy brome) is an exotic annual weed (recently?) introduced to the United States (ca. 1890) . Since its introduction, B. tectorum has been extremely effective at invading the Intermountain West, displacing native vegetation and causing extensive loss […]
Prolactin’s Effect on CCL28 Gene Expression
Susanne Linderman and Dr. Eric Wilson, Microbiology and Molecular Biology The purpose of my project was to determine whether or not the hormone prolactin had an effect on CCL28 gene expression. CCL28 is a chemotactic protein (chemokine) that attracts IgA antibody secreting cells (ASC) to the lactating mammary gland. Receptor proteins on the surface of […]
Stable Isotope Ratios in Leg Hairs A Better Diagnostic Tool for Eating Disorders
Stephanie Lindblad and Professor Beverly Roeder, Biology Anorexia and bulimia are eating disorders that are extremely harmful and difficult to accurately diagnose. Currently the most frequent methods of diagnosis are subjective interviews and questionnaires. One example of these psychological diagnostic tools is the DSM-IV test, which has some serious problems associated with it. It relies heavily on […]
Does SNAP-25 Act as a V-SNARE?
Nathan La Monica and Dr. Dixon Woodbury, Physiology & Developmental Biology SNAP-25, a protein that is found abundantly in the brain, is a key player in the process of releasing neurotransmitters. Vesicles, or small spheres of lipid membranes, contain neurotransmitters and have numerous proteins that extend outward from the vesicle. To release the neurotransmitters proteins […]
