Zusammenfassung:	A method of cloning endogenously modified Streptomycetes DNA, which is normally rejected by restrictionless heterospecific hosts, is disclosed. The method uses bacteriophage lambda to construct a genomic library of modified Streptomycetes DNA; such lambda-containing Streptomycetes DNA is replicated to provide a source of non-modified Streptomycetes DNA. This non-modified DNA is subcloned into a selectable cloning vector and used to transform restrictionless hetero-specific hosts. The transformants can then be screened for clones containing genes of interest.
