Jeffrey Schachterle and David Erickson, Microbiology and Molecular Biology Introduction The bacteria Yersinia pestis is the causative agent of bubonic plague, and its ability to form biofilm in fleas is essential for plague transmission by fleas [1]. Y. pestis recently evolved from Y. pseudotuberculosis (Y. pstb), and the two have nearly identical genomes. Y. pestis […]

Cameron Woodward and William McCleary, Department of Microbiology and Molecular Biology Introduction Phosphate intake by Escherichia coli serves as a good model system to study phosphate intake by other bacteria. The pho phosphate uptake system used by E. coli is well conserved in pathogens like Vibrio cholerae (1). To better understand this important mode of […]

Connor Woodward and Brent Nielsen, Microbiology and Molecular Biology Introduction Dna2 is a protein that is known to be essential for DNA replication in human and yeast mitochondria. In these organisms it acts as both a helicase and an endonuclease. In the model plant Arabidopsis thaliana an ortholog of Dna2 exists but has never been […]

Hyrum Shumway and Dr. Steven Johnson, Microbiology and Molecular Biology Introduction Hershey and Chase proved DNA to be the genetic material of life in 1952. The structure of DNA largely eluded investigators until Watson and Crick discovered it a year later. These two landmark experiments laid a foundation so that questions in transcription, translation, gene […]

Josh Yates and Dr. Laura Bridgewater, Microbiology & Molecular Biology Introduction Bone morphogenetic proteins (BMPs) contribute to many different aspects of development including mesoderm formation, heart development, neurogenesis, skeletal development, and axis formation. They have previously been recognized only as secreted growth factors. Recently, researchers in the Bridgewater lab discovered a nuclear variant of Bone […]

Marcus Vranes and Dr. Steven Johnson, Molecular Biology Introduction Recent studies have attempted to discover the correlation that exists between DNA methylation and nucleosome positioning, but none have explored the direct effect of DNA methylation on nucleosome formation and positioning. This research is directly testing the effects of DNA methylation on nucleosome positioning, and whether […]

Lance A. Stutz and Dr. Brian Poole, Microbiology and Molecular Biology Introduction Epstein-Barr virus (EBV) is a common infectious agent which infects more than 95% of adults worldwide (1). EBV is related to a number of diseases, including cancers such as Burkitt’s lymphoma and nasopharyngeal carcinoma, and is the causative agent of infectious mononucleosis (2). […]

Cameron Sargent and Dr. Sandra Burnett, Microbiology and Molecular Biology Introduction Over the past few years at Brigham Young University and other colleges nationwide, members of the Phage Hunters program have endeavored to find and analyze novel mycobacteriophage in an attempt to create new treatment and research methods for the pathogen Mycobacterium tuberculosis. Not only […]

Bryan Merrill and Dr. Sandra Burnett, Department of Microbiology and Molecular Biology Introduction Honey bees pollinate one third of the crops in the U.S. diet. The spore-forming bacterium Paenibacillus larvae causes American Foulbrood (AFB), a highly contagious disease that is lethal in honey bee larvae. P. larvae is the most serious pathogen affecting honey bees. […]
