Abstract The metal-responsivesmt operator/promoter region ofSynechococcus PCC7942 was fused to theluxCDABE genes ofVibrio fischeri. Plasmid DNA (pJLE23) carrying this fusion conferred metal ion-inducible luminescence to transformed cyanobacteria.Synechococcus PCC7942 (pJLE23) was sensitive to ZnCl2 concentrations within a range of 0.5–4 μM as demonstrated by induction of luminescence. Trace levels of CuSO4, and CdCl2 were also detected.
