ABSTRACT OF THE DISCLOSURE Novel compositions and methods for cloning DNA in a broad range of Gram-negative bacteria. Relatively small vectors are prepared substantially free of DNA sequences coding for transfer functions, while having a broad host range replication function. While the plasmid is not self- transmissible, it is transmissible by means of a helper plasmid, which desirably has a narrow host range replication function. Exogenous DNA may be inserted into the first plasmid and conjugally transferred to the target host by means of a convenient bacterial host.
