Using an Escherichia coli-Streptomyces shuttle vector derived from a bacterial artificial chromosome (BAC), we developed methodologies for the construction of BAC libraries of filamentous actinomycetes. Libraries of Streptomyces coelicolor, the model actinomycete, and Planobispora rosea, a genetically intractable strain, were constructed. Both libraries have an average insert size of 60 kb, with maximal insert larger than 150 kb. The S. coelicolor library was evaluated by selected hybridisations to DraI fragments and by end sequencing of a few clones. Hybridisation of the P. rosea library to selected probes indicates a good representation of the P. rosea genome and that the library can be used to facilitate the genomic analysis of this actinomycete.
