The library is described in an upcoming publication, still in press at the time thiscatalog was printed: Rondon, M. R., S. J. Raffel, R. M. Goodman, and J. Handelsman. 1999. Towardfunctional genomics in bacteria: analysis <strong>of</strong> gene expression in Escherichia coli from a bacterial artificialchromosome library <strong>of</strong> <strong>Bacillus</strong> cereus. Proc. Natl. Acad. Sci. USA 96: (in press). We thank these members<strong>of</strong> the University <strong>of</strong> Wisconsin Plant Pathology B. cereus group for their generosity.The library was constructed in a bacterial artificial chromosome vector in E. coli, a system that <strong>of</strong>fers somedistinct advantages over YAC vectors. First, BAC libraries appear to be quite stable. Secondly, manybacterial genes will be expressed in E. coli. Indeed, Rondon, et al. were able to detect six <strong>of</strong> ten B.cereus-specific activities they screened for among the E. coli clones. Thirdly, BAC clones can bemanipulated rapidly and easily for electrophoretic analysis, DNA sequencing, and mutagenesis.The BGSC will distribute copies <strong>of</strong> the library at no cost to serious researchers at academic, government,and other non-pr<strong>of</strong>it organizations. Interested parties at for-pr<strong>of</strong>it companies are encouraged to contactthe BGSC to discuss distribution options. As individual clones are better characterized, they will be madeavailable separately as well.Description <strong>of</strong> LibraryDNA source:<strong>Bacillus</strong> cereus UW85E. coli host strain: DH10BCloning vector:pBeloBAC11 (see Shizuya, et al.1992.
