3 new shuttle cloning vectors for gene transfer into Escherichia coli and Anacystis nidulans have been constructed by utilizing the cyanobacterial origin of replication of the small plasmid pANS from A. nidulans . 2 of these new vectors, pXB7 (pDPL13 derivative) and pECAN8 (pUC8 derivative), convey ampicillin resistance, and transform A. nidulans with relatively high frequencies. Vector pXB7 has 10 unique cloning sites; pECAN8 contains 4 cloning sites within the lacZ gene permitting rapid detection of DNA inserts in the presence of Xgal. The third vector, pKBX, has a lower transformation frequency but adds kanamycin resistance as a selectable gene for shuttle vectors of cyanobacteria.
