UNLABELLED Engaging large numbers of undergraduates in authentic scientific discovery is desirable but difficult to achieve. We have developed a general model in which faculty and teaching assistants from diverse academic institutions are trained to teach a research course for first-year undergraduate students focused on bacteriophage discovery and(More)
The bacteriophage population is large, dynamic, ancient, and genetically diverse. Limited genomic information shows that phage genomes are mosaic, and the genetic architecture of phage populations remains ill-defined. To understand the population structure of phages infecting a single host strain, we isolated, sequenced, and compared 627 phages of(More)
To increase science literacy and appreciation among nonscience majors, we offered a course in which 20 non-STEM (science, technology, engineering, math) undergraduates participated in a unique, two-semester research experience. Each student isolated and characterized his or her own bacteriophage from soil samples. One bacteriophage was selected for(More)
Mycobacteriophages are viruses that infect mycobacterial hosts such as Mycobacterium smegmatis and Mycobacterium tuberculosis. All mycobacteriophages characterized to date are dsDNA tailed phages, and have either siphoviral or myoviral morphotypes. However, their genetic diversity is considerable, and although sixty-two genomes have been sequenced and(More)
GlnR plays a major role in regulation in Bacillus subtilis by directly controlling expression of glutamine synthetase (GS) as well as several genes involved in nitrogen metabolism. A GlnR homolog from Staphylococcus aureus was found to complement a B. subtilis glnR mutant, regulating GS levels and glnRA expression in a nitrogen-dependent manner. In a GS(More)
Bacillus thuringiensis Kurstaki, a bacterium that is a source of biopesticides and a safe simulant for pathogenic Bacillus species, was used to isolate seven unique bacteriophages. The phage genomes were sequenced and ranged in size from 158,100 to 163,019 bp encoding 290-299 genes, and the GC content of ~38% was similar to that of the host bacterium. All(More)
