Abstract:
An expression cassette was constructed, which has the bacterial bleomycin (Bm) resistance-encoding gene (ble) fused to the Dictyostelium discoideum actin-6 promoter, with a segment of 3'-flanking DNA from the actin-8-encoding gene placed downstream from the ble gene to serve as a transcription terminator. Plasmid pMUW161, which contains this cassette and the D. discoideum plasmid Ddp2 origin of DNA replication, transformed D. discoideum with high efficiency under Bm selection. Hence, this construct is useful as a dominant selectable marker for D. discoideum.
